Abstract:

The interface bonding method has a great influence on the mechanical properties of aluminum foam sandwich (AFS). This study aims to investigate the effect of different interface bonding methods on the mechanical properties of AFS. In this paper, the metallurgical-bonding interface-formation mechanism of AFS prepared by powder metallurgy was investigated. The shear properties of metallurgical-bonded AFS were determined by the panel peeling test. The flexural properties and energy absorption of metallurgical-bonded and glued AFS were analyzed through the three-point bending test. The results show that the magnesium, silicon, and copper elements of the core layer diffuse to panels and form a metallurgical composite layer. The metallurgical-bonding strength between the panel and core layer is higher than that of the foam core layer. The peak load of metallurgically-bonded AFS is 24% more than that of glued AFS, and energy absorption is 12.2 times higher than that of glued AFS.

Abstract:

In order to improve the surface Performance of thick copperplate, A Ni- Cr alloy coating metallurgically bonded onto thick copperplate is performed by YAG laser remelting plasma spraying coating process. In laser cladding processing, it is difficult to get good metallurgical bonding between the layer and copperplate. Plasma spraying technology is developed to get a alloy layer on the surface of thick copperplate, and then using YAG laser cladding method to make a coating. The results of Micro organization analysis indicate that the cladding layer and substrate form favorable metallurgical bonding, as a narrow metallurgical bonding zone, about 3m in thickness. The structure is more compact compared with witch of plasma spraying coating, and the crystal grains are refined grain.

Abstract:

The article analyzes multiple definitions of enterprise investment policy. It reveals the scientists’ judgments on the essence of the enterprise investment policy and presents the term definitions integrated with the scientific approach, applying semantic-syntactic criteria in the ontological analysis methodology. In terms of the scientific approaches, suggested by the authors, the objectives of the industrial enterprise investment policy, methods for evaluating the investment policy in general, and the capital investment projects specifically are considered. The authors outline the main problematic issues that require further in-depth research. Differences in the objectives of the investment policy between the enterprises inside the branch, as well as factors of influence on institutional conditions of investment into the metallurgical industry are identified based on the analysis of the strategic profile of the national metallurgical companies and analytical data of the World Steel Association. The authors give the essential criteria of the investment activity efficiency in the field, among which are: fluctuation in world metal prices; the national currency exchange rate volatility; vertical integration in metallurgic enterprise management; oligopoly in the domestic metallurgical market. Approaches, proposed by the authors, are relevant both methodologically and practically, and encourage to further investigation of the enterprise investment policy and investment activity specifics in the metallurgical industry sector.

Abstract:

The iron and steel industry is one of the largest sources of waste materials, primarily in the form of steelmaking dusts, sludge and slag. Those wastes are a serious threat to the environment. Main precondition for the protection of natural resources in the environment is to recover raw material and energy from waste. The use of waste as raw materials does not involve the storage and creates the possibility of closure of the existing landfill. The article presented utilization of same metallurgical waste containing 4-20 wt. % zinc in non-metallurgical industry. Performed chemical analyzes of pollutants contained in waste tested (dusts, sludge and slag) and in manufactured products (cement bricks, ceramic construction materials, colored glass products and slag for road construction). Aqueous extracts analysis results were compared with the maximum values for the sewage entering into water and soil. The performed research proves that proposed technologies (production of cement clinker, construction bricks, hollow glass, decorated glass) do not pose threat to environment. Harmful impurities are eluted from the products – clinker, constructions bricks and slag after the recovery of zinc recovery. Proposed technologies substitution of primary raw materials recyclable materials can reduce environmental degradation.

Abstract:

The metallurgical aspects of weld cracking in Ni-based superalloys remain relatively unexplored in existing research. The present study performed comprehensive metallurgical and manufactural investigations into the weldability of an Ni-based superalloy, CM247LC, from the viewpoint of the liquation cracking behavior and its susceptibility. Metallurgical solutions to suppress the liquation-cracking susceptibility were derived via the visualization-based Varestraint test, and the possibility of liquation crack-free welding was explored by employing pre-weld heat treatments and laser beam welding. The alloy that was subjected to aging treatment exhibited the lowest liquation-cracking susceptibility (liquation cracking temperature range: 66 K), while the as-cast alloy specimen exhibited the highest liquation-cracking susceptibility (liquation cracking temperature range: 620 K). The metallurgical mechanisms of the liquation cracking susceptibility of as-cast CM247LC weld were elucidated via microstructural analyses and thermodynamic calculations. The suppressed liquation cracking susceptibility of the aged CM247LC can be attributed to the MC-type carbide fraction and homogenized matrix phase, as compared with those of as-cast CM247LC. The aged CM247LC specimen was subjected to gas tungsten arc welding to validate its minimal liquation-cracking susceptibility. The results confirmed the suppression of liquation cracking, due to the low susceptibility of the specimen. However, crackfree welds could not be obtained. Finally, metallurgically sound welds without liquation cracks were successfully obtained via laser beam welding. The outcomes of the present study will facilitate the generation of electric power from fossil fuels via a clean and efficient gas turbine-based power generation cycle.

Abstract:

For the prediction of mechanical properties of hot strip from production conditions by metallurgically oriented computer assisted simulation it is necessary to model all the numerous metallurgical processes leading to the microstructure of the finished product. The relevant microstructural parameters, calculated in this way, finally are converted into mechanical properties by application of suitable algorithms. At ThyssenKrupp Stahl such a metallurgically oriented simulation system has been developed and established under the name TK-StripCam. It is based on empirical-physical models. It allows on the one hand to predict important mechanical properties with considerable precision from production parameters as rolling schedule, cooling conditions etc. On the other hand by means of the simulation system course and kinetics of each metallurgical process included may be studied. It is evident that in a steel plant such a powerful tool finds a great variety of applications extending from offline use as a tool for development of steels and processes to inline use in the rolling mill to control the mechanical properties during production. In this work details of the philosophy and structure of the simulation system and examples for its application are presented.

Abstract:

The article discusses the results of the analysis covering the current state of the external business environment of metallurgical enterprises and the level of digitalization of significant metallurgical leaders in Russia. Based on them, the authors examined the possibilities and risks that are associated with the digitalization of the metallurgical industry, as well as their effects on the competitive ability of such industry in Russia in general. The general analysis of the metallurgical industry portrays the economic and political instability caused by supply chain disruption, anti-Russian sanctions, the downturn driven by the coronavirus pandemic and general geopolitical tension that has been dictating the performance of metallurgical enterprises for a long period and thus affects their sustainable development. The authors analyzed findings of the SWOT analysis of metallurgical enterprises, using Severstal PJSC as an example, and developed strategic reactions that serve as the foundation for the development of the digitalization strategy of the metallurgical industry. In addition, the evaluation of the connection between the level of digitalization of metallurgical enterprises’ performance and their profitability demonstrates that there is a direct connection. The level of digitalization of business processes of a metallurgical enterprise has a direct impact on its competitive ability, implying the necessity to establish a set of strategic reactions that make it possible to develop a strategy for digitalization of metallurgical enterprises’ business processes. This strategy helps increase their performance and minimize risks, resulting in an increase in the efficiency and competitive ability of the Russian metallurgical industry on the global market. The evaluation of the efficiency of the digitalization strategy proposed reveals that its successful implementation contributes to a significant increase in the metallurgical enterprises’ profitability.

Full text

Abstract:

The increase of long-term service exposure to thermal power plants, the tendency toward intermediate and cyclic operation to meet the change in electric power demand and supply situation, and the requirement to develop higher-temperature and higher-pressure plants have led to increasing attention towards the reliability improvement. This paper presents findings from field experiences of cracking or failure and two types of damage analyses—(1) creep-fatigue damage analysis based on the life fraction rule and (2) metallurgical damage analysis—of boiler pressure parts that have been exposed to long-term elevated temperature service. The field experiences are (1) cracking or failure of thick-walled Type 316 stainless steel pressure parts in the main steam line of an ultra-supercritical thermal power plant and (2) dissimilar metal weld joints for boiler tubing. The creep-fatigue damage analysis of these pressure parts showed a reasonable correspondence with the field experience. According to the creep-fatigue damage analysis and the metallurgical damage analysis, most of damage was restrained creep mode phenomenon without deformation. The creep damage was composed of metallurgical damage and mechanical damage such as microvoids and structural defects. One method of simulating field experienced creep damage was proposed and performed. As a result, the process of creep voids being generated and growing into cracks without deformation was successfully observed. Also a review of the current status of nondestructive detecting methods of creep damage suggests that detecting the creep voids metallurgically is more practical at the present time than doing so analyzing the changes in physical properties of the material. It is also suggested that, in the metallurgical approach, detecting the creep voids and cracks by replica method and anlayzing precipitates for evaluation of material deterioration by precipitate extraction method will make it possible to successfully address the problem of plant equipment creep damage evaluation and life prediction.

Full text

Abstract:

Increasing global cement and steel consumption means that a significant amount of greenhouse gases and metallurgical wastes are discharged every year. Using metallurgical waste as supplementary cementitious materials (SCMs) shows promise as a strategy for reducing greenhouse gas emissions by reducing cement production. This strategy also contributes to the utilization and management of waste resources. Controlled low-strength materials (CLSMs) are a type of backfill material consisting of industrial by-products that do not meet specification requirements. The preparation of CLSMs using metallurgical waste slag as the auxiliary cementing material instead of cement itself is a key feature of the sustainable development of the construction industry. Therefore, this paper reviews the recent research progress on the use of metallurgical waste residues (including blast furnace slag, steel slag, red mud, and copper slag) as SCMs to partially replace cement, as well as the use of alkali-activated metallurgical waste residues as cementitious materials to completely replace cement for the production of CLSMs. The general background information, mechanical features, and properties of pozzolanic metallurgical slag are introduced, and the relationship and mechanism of metallurgical slag on the performance and mechanical properties of CLSMs are analyzed. The analysis and observations in this article offer a new resource for SCM development, describe a basis for using metallurgical waste slag as a cementitious material for CLSM preparation, and offer a strategy for reducing the environmental problems associated with the treatment of metallurgical waste.

Abstract:

Abstract Several samples of dusts from steel and coke plants (collected mostly with electro filters) were subjected to the investigation of content of mineral phases in their particles. Additionally, sample of bog iron ore and metallurgical slurry was studied. Next, the magnetic susceptibility of all the samples was determined, and investigations of iron-containing phases were performed using transmission Mössbauer spectrometry. The values of mass-specific magnetic susceptibility χ varied in a wide range: from 59 to above 7000 × 10−8 m-3·kg−1. The low values are determined for bog iron ore, metallurgical slurry, and coke dusts. The extremely high χ was obtained for metallurgical dusts. The Mössbauer spectra and X-ray diffraction patterns point to the presence of the following phases containing iron: hematite and oxidized magnetite (in coke and metallurgical dusts as well as metallurgical slurry), traces of magnetite fine grains fraction (in metallurgical dusts), amorphous glassy silicates with paramagnetic Fe3+ and Fe2+ ions, traces of pyrrhotite (in coke dusts), α-Fe and nonstoichiometric wüstite (in metallurgical slurry), as well as ferrihydrite nanoparticles (in bog iron ore). For individual samples of metallurgical dusts, the relative contributions of Fe2+/3+ ions in octahedral B sites and Fe2+ ions in tetrahedral A sites in magnetite spinel structure differs considerably.

Full text

Abstract:

Automatic identification of metallurgical phases based on thresholding methods in microstructural images may not be possible when the pixel intensities associated with the metallurgical phases overlap and, hence, are indistinguishable. To circumvent this problem, additional visual information about the metallurgical phases, referred to as textural features, are considered in this study. Mathematically, textural features are the second order statistics of an image domain and can be distinct for each metallurgical phase. Textural features are evaluated from the gray level co-occurrence matrix (GLCM) of each metallurgical phase (ferrite, pearlite, and martensite) present in heat-treated ASTM A36 steels in this study. The dataset of textural features and pixel intensities generated for the metallurgical phases is used to train supervised machine learning classifiers, which are subsequently employed to predict the metallurgical phases in the microstructure. Naïve Bayes (NB), k-nearest neighbor (K-NN), linear discriminant analysis (LDA), and decision tree (DT) classifiers are the four classifiers employed in this study. The performances of all four classifiers were assessed prior to their deployment, and the classification accuracy was found to be >97%. The proposed technique has two unique advantages: (1) unlike pixel intensity-based methods, the proposed method does not misclassify the grain boundaries as a metallurgical phase, and (2) the proposed method does not require the end-user to input the number of phases present in the microstructure.

Abstract:

According to the classical model of the metallurgical raw material supply chain proposed by Eugeniy Chernykh, the Eneolithic and Early Bronze age cultures of Ukraine were completely dependent on imported raw material. It seems that the main supplier of metal, as well as some complete goods during the 5th and 4th Millennia BC, was the ‘Carpatho-Balkan Metallurgical Province (CBMP)’ while during the 3rd Millennium BC, the provision chain was reoriented towards the ‘Circumpontic Metallurgical Province (CMP)’. Yet, new discoveries that were made during the 1990s-2020s indicate the need for the amendment of such a model. This is the aim of the current paper. In the following text, the concept of four Ukrainian local metallurgical provinces and two metalworking foci will be introduced. The typology and dating of the recently discovered metal objects as well as metallurgical tools will be provided. The question of the existence of domestic metallurgical raw material deposits will be discussed.

Structural changes in the production of metallurgical products in Ukraine are studied. The importance of this sector in the Ukrainian industry and the high level of competitiveness in the world market are noted. The article determines that the key metallurgical industries are concentrated in three oblasts: Dnipropetrovska, Donetska, and Zaporizka, which account for about 80% of metallurgical output and about 90% of metallurgical exports in Ukraine. At the same time, metallurgy became the main industrial sector of the indicated regions: in Donetska oblast, the share of metallurgy in the region’s industry is 53.20%, in Zaporizka - 39.50%, in Dnipropetrovska - 34.20% (in 2021). Taking into account the fact that active military operations on the territory of Ukraine during 2022 had a significant impact on business conditions, the article examines the impact of the war on the activities of the largest metallurgical enterprises. In particular, physical destruction of fixed assets, logistics, shortage of energy supply, etc. The share of the largest metallurgical enterprises in the metallurgical industry until 2022 is determined, and changes in the production activity of enterprises after a full-scale military invasion of the territory of Ukraine are indicated. The article notes that in 2022, about 30% losses in production can be predicted for the metallurgical enterprises of Dnipropetrovska oblast, about 50% - in Zaporizka oblast, and almost all metallurgical enterprises of Donetska oblast have suspended their work. Practical examples of preserving the functional capacity of the enterprise due to effective decision-making are given. In particular, some enterprises are moving their production facilities to a safer area (in particular, to the west of the country); the most destroyed industries are filing lawsuits in international courts for compensation of damages at the expense of the aggressor (Russia); some enterprises are changing the sales market to optimize the costs of logistics and other things. Variants of solutions to the specified problems are offered to restore the work of metallurgical enterprises and strengthen their competitiveness in the domestic and foreign markets.

Abstract:

This article presents the results of a research on the recycling of wastes from metallurgical plants in the city of Pavlodar at a steel smelting plant KSP Steel. The pellets were produced with aspiration dust and mixed with steelmaking (white) slag, ferrous sand, scale. The produced pellets were fired at a temperature of 600 ° C. The experience with the use of 20% white slag, 20% ferrous sand mixed with aspiration dust and 10% mill scale shows, after burning in a furnace, quite satisfactory strength, which is 80 kg / pellet. The principal possibility of steelmaking using pellets is shown. A positive effect on the recovery process of steelmaking has a carbonaceous reducing agent, which is in the composition of the charge. The pellets are fully capable of partially replacing iron and steel scrap, reducing the cost of metal.

Abstract:

Abstract The article characterizes microstructures of metallurgic slag of varying age remaining from the production of iron and steel and the Zn-Pb ore processing in relation to magmatic rocks and ores. Based on microscopic observations - among others - hypocrystalline, hyaline and felsite (characteristic for magmatic rocks) microstructures were observed in the slag. Also microstructures related to ores, including framework and dendritic, colomorphic and corrosive structures were noted. The diversity of the microstructures presented in the article is a result of the differentiation in the formations of individual components of the slags, which depends, inter alia, on the method and the rate of cooling of the alloys.
