Abstract:
Problem statement. Development of an effective technology for the skin-rolling will allow the production of hot-rolled sheet products with quality indicators that meet the requirements of standards for cold-rolled sheets. Consumers with significant economic benefits will be able to use relatively inexpensive hot-rolled sheets instead of expensive cold-rolled sheets. The purpose of the article: establishment of the effect of skin-rolling to various technological schemes for the production of hot rolled fine and thickness rolled for cold stamping on the structure and properties of the metal. Conclusion. The patterns of the formation of the structure and properties after skin-rolling of hot rolling sheet steel and plate steel for cold stamping are established. It is shown that with an increase in the degree of deformation during skin-rolling in the unit cutting unit, there is a decrease in the plasticity of hot-rolled plate steel strips of low carbon steels. As a result of heat treatment and skin-rolling on a separately located mill of hot rolled, thin-sheet low carbon steel, the plasticity of the metal rises and a homogeneous structure is formed in accordance with the requirements of ДСТУ 2834-94. Obtaining hot-rolled thin-sheet steel with quality indicators at the level of requirements for cold-rolled metal will allow the use of hot-rolled steel instead of cold-rolled one, which will ensure an increase in labor productivity and savings electricity.

Abstract:
This study investigated the microstructure and mechanical properties of hot-rolled and cold-rolled medium-Mn transformation-induced plasticity (TRIP) steel. The experimental steel, processed by quenching and tempering (Q & T) heat treatment, exhibited excellent mechanical properties for hot-rolled and Q & T steels (strength of 1050–1130 MPa and ductility of 16–34%), as well as for cold-rolled and Q & T steels (strength of 878–1373 MPa and ductility of 18–40%). The mechanical properties obtained after isothermal holding at 775 °C for one hour for cold-rolled/Q & T steel were superior to that of hot-rolled/Q & T steel. Excellent mechanical properties were attributed to the large amount of retained austenite, which produced a discontinuous TRIP effect. Additionally, the differences in mechanical properties correlated with the morphology, stability and content of retained austenite. The cold-rolled sample, quenched from 650 °C (CR 650°C) had extensive TRIP effects in the middle and late stages of the deformation, leading to better mechanical properties. The fracture modes of the hot-rolled sample, quenched from 650 °C, and the cold-rolled sample quenched from 650 °C, were ductile fractures, resulting in excellent ductility.

Abstract:
This paper provides the study of aging hot dip galvanized rolled products of low-carbon high-resistance automotive steels featuring good formability, weldability and dent-resistance. The authors carried out the experiment to obtain data on the period of warranty of mechanical properties of rolled products manufactured at OJSC Magnitogorsk Iron and Steel Works at storage and processing at the customer's site. The following assortment of hot-dip galvanized rolled products was selected for the experiment: 08ps and DX52D steels rolled coated products, rolled products of high-strength HX220YD and 006/IFgr steels as well as those of high-strength steels hardening at coating afterbaking – HX180BD and A341-A5. Tensile test was carried out at the experimental stage to determine changes of mechanical properties of the assortment under study due to aging. Based on the experimental outcome, the graphs were plotted, which clearly demonstrated changes of mechanical properties of rolled products due to aging. It has been found that the warranty period for mechanical properties of hot-dip galvanized rolled products of DX52D, HX220YD and 006/IFgr steels is 3 to 6 months since the confirmation of the delivery date; the storage period for hot-dip galvanized rolled products of HX180BD and A341-A5 steels shall be no more than 3 months. Aging 08ps steel hot-dip galvanized rolled products begins in as little as 10 days.

The fire-resistant hot-rolled H-beam steel is the newly developed structure material. The development situation of the fire-resistant H-beam steel is briefly introduced. The chemical composition, microstructure, room temperature and high temperature mechanical properties and weldability of several batches of the developed domestic fire-resistant hot-rolled H-beam steels are comprehensively analyzed. The results show that the newly developed hot-rolled fire-resistant H-beam steel has very high room temperature strength, certain high temperature strength, good welding performance, but the toughness needs to be further improved.

Abstract:
Hot- and cold-rolled steel sheets are the most important substrate materials for enamelling applications. Currently, industry is actively seeking ways to widen the area of application of hotrolled steel sheets for double-face enamelling. Another important task is search for new steel compositions that might substitute for currently used open-coil annealed, cold-rolled steel sheet for direct white enamelling applications. The purpose of this research project was the investigation of influence of chemical composition and processing conditions of several microalloyed steels on mechanical properties and fish-scale resistance of hot and cold rolled sheets. The results show that a high fish-scale resistance of the hot-rolled steel is achieved by creating a high volume fraction of fine precipitates (nitrides, carbides, carbonitrides, sulphides, etc.). By partial replacement of titanium with other carbide and nitride forming elements, such as niobium and/or boron, the suitability of cold-rolled IF steels for white direct-on enamelling can be remarkably improved without open-coil annealing. However, the processing conditions have to be tuned to ensure high fish-scale resistance without impairing formability.

Abstract:
The addition of titanium is a well-known microalloying concept for hot rolled structural steels. Concerning advanced high strength steels for the automotive sector, the use of Ti microalloying (usually with Nb-V) has been an active research area. However, Ti addition has not been explored in depth. For the current contribution, a laboratory hot rolled 0.2C-2.4Mn-1.5Si steel with and without Ti addition was studied. Mechanical testing of the hot strip revealed a very high UTS (1GPa) for the Ti added steel, whilst for the unalloyed chemistry the UTS was some 300 MPa lower. Observation of the hot rolled microstructures via optical microscopy showed a significantly higher hardenability for the Ti added steel. Moreover, X-ray diffraction analysis indicated a significant amount of retained austenite in the Ti added strip, which transformed completely to martensite after the tensile test. Further analysis via TEM and chemical extraction indicated that Ti was present both as Ti (C,N) precipitates and in solution. Finally, in light of these observations, the possible mechanisms leading to the enhanced hardenability observed for the Ti added hot rolled strip steel were discussed.

With the help of orientation distribution function (ODF) analysis, experiments of different hot band grain microstructure 0.33% silicon steel were cold-rolled and annealed in the laboratory，to study the effect of the microstructure hot-rolled steel strip for cold rolled non-oriented silicon steel microstructure and texture of recrystallization annealing. The results show that hot rolled microstructure on cold rolled Non-Oriented Electrical Steel cold-rolled sheet evolution of texture and recrystallization have important influence, the quiaxed grain structure of steel by cold rolling and recrystallization annealing, the recrystallization speed than the fiber grain-based mixed crystals recrystallization fast , With the equiaxed grains made of cold rolled silicon steel after annealing the {110}<UVW> texture components was enhanced and {100}<uwv> texture components weakened. Different microstructure condition prior to cold rolling in the recrystallization annealing process the texture evolution has the obvious difference, the equiaxial grain steel belt cold rolling and annealing, has the strong crystal orientation. This shows that the equiaxed grain when hot microstructure is detrimental to the magnetic properties of cold-rolled non-oriented silicon steel to improve and increase.

Abstract:
Abstract The effect of rare earth Y on precipitates and textures of the grain-oriented silicon steels, the composition, morphology, size, quantity of inclusions and texture evolution of hot-rolled and cold-rolled oriented silicon steel containing rare earth Y were studied using transmission electron microscopy, field emission scanning electron microscope, and electron backscatter diffraction. The results show that there are mainly spherical or ellipsoidal Y2O2S precipitates in the Y bearing silicon steel. Rare earth treatment effectively improves the precipitates’ morphology and restrains the precipitation of the long-strip MnS in the hot-rolled plate. Meanwhile, the microstructure is more uniform, and the recrystallized grains on the surface and the fiber structure in the central layer are larger after hot rolling compared with Y-free steel. Furthermore, with the addition of rare earth Y, the unfavorable brass texture and rotational cube texture in the hot-rolled plate are reduced. Meanwhile, the number of shear bands is increased and the strength of the favorable {111} 〈112〉 texture is improved in the cold-rolled plate, which helps develop the Goss texture during the annealing process.

Abstract:
Dual-phase steels are the most important AHSS grades for automotive applications. Microalloying elements such as Ti, Nb or B are widely used to improve the strength of dual-phase steels. Thus, understanding the influence of these elements on the microstructure and mechanical properties of dual-phase steels along the processing route is critical for the development of new steel grades. In this work, different microalloying elements were investigated, separately or in combination. The influences of the different elements on the microstructure and mechanical properties of dual-phase steels in the hot-rolled condition and after annealing of cold-rolled material. Dilatometer measurements were performed to investigate phase transformation during a typical continuous annealing treatment of dual-phase steel after cold rolling. It was shown that, for example, Ti has a strong influence on the mechanical properties of hot-rolled material while its influence on annealed materials after cold rolling was relatively small. Conversely, B had a strong influence on cold-rolled materials but an insignificant influence on hot-rolled materials.

Abstract:
The work is in the form of a project aimed at furthering the understanding of metallurgical interactions during the processing of hot rolled CMn (-Si) steel grades. The aim has been achieved through a number of complimentary investigations. Through-coil mechanical testing and metallographic examination, coupled with detailed analyses of relevant process parameters, have highlighted the typical properties and property variations within Corus' CMn (-Si) products. Deformation dilatometry experiments have allowed the transformation behaviour of CMn (-Si) compositions to be assessed and compared with that predicted by transformation theory. Laboratory-scale rolling and cooling experiments have demonstrated the effects of composition and process variations on steel properties. These combined discoveries have contributed to a deeper understanding of the metallurgy of CMn (-Si) steel manufacture. The project has illustrated where product design changes can contribute to enhanced properties, helping Corus to ensure the long-term success of its CMn (-Si) steels within the automotive market.

Abstract:
High strength, low alloy, hot rolled strip steels with yield stresses in the range 700 to 1300MPa are required for the Lifting and Excavating product sector. Improved combination of strength and toughness in these high strength steels is desired, requiring a detailed understanding of the relationship between microstructure and mechanical properties. In this work 12mm thick 700MPa yield stress strip steels with fully bainitic microstructures, with different compositions and/or processing conditions, have been studied. The microstructures of the steels were investigated with both optical microscopy and SEM. Micro-hardness and Charpy impact tests (at different temperatures) were carried out to investigate the mechanical properties, followed up with fracture surface analysis and unit crack path (UCP) analysis. Three types of bainitic microstructures were identified and quantified, including upper bainite, lower bainite and granular bainite. The fracture surface and UCP analysis indicating that granular bainite is detrimental to toughness, but cannot necessarily be avoided in the steels investigated; while the presence of a small amount of lower bainite (above 5%) was found to improve the impact toughness significantly. Continuous cooling transformation (CCT) diagrams for steels with different compositions were produced, which allowed investigation of the phase transformation behaviour and selection of optimum chemical composition/coiling temperature for improved properties. The effects of alloying elements (B, Mo and V) on the transformation behaviour have been confirmed through the experiments. An optimised combination of alloying and coiling temperature has been proposed and validated via investigating plant trial products with similar alloying and processing parameters.

Abstract:
Hot rolling process is heat input process. The heat energy in hot rolled steel coils can be utilized. At SSAB Strip Product Borlänge when the hot rolled steel coils came out of the hot rolling mill they are at the temperature range of 500°C to 800°C. Heat energy contained by the one hot rolled steel coil is about 1981Kwh whereas the total heat energy for the year 2008 is 230 GWh/year.The potential of heat is too much but the heat dissipation rate is too slow. Different factors on which heat dissipation rate depends are discussed.Three suggestions are proposed to collect the waste heat from hot rolled steel coils.The 2nd proposal in which water basin is suggested would help not only to collect the waste heat but to decrease in the cooling time.

Abstract:
The mechanical anisotropy of hot rolled coils for linepipe grades in the range between X52 and X80 have been investigated in terms of tensile strength and Charpy impact toughness. Samples were taken in different orientations with respect to the strip rolling direction: 0, 30, 45, 60 and 90 degrees. Tensile tests were performed on round tensile specimens to avoid the need for strip levelling. Results from this investigation reveal that the hot rolled coils display different degrees of anisotropy varying as function of strength level and thickness. The material anisotropy is reflected in variations in yield, tensile strength and ovality of the gauge section after fracture. At the same time, variations of the CVN absorbed energy in the upper shelf energy and in the ductile to brittle transition temperature were also observed. Finally, detailed texture studies revealed a relation between mechanical anisotropy and crystallographic texture.

Abstract:
Abstract During the hot rolling of carbon steel, austenite phase transforms into a pearlitic morphology, which essentially is a matrix of ferrite lamellae (α-Fe) and cementite (Fe3C). This transformation occurs at the cooling bed after an equalisation temperature of around 600 °C. Pearlitic steels find their use in ropes for bridges and elevators, rails, and tyre cords among others. Characterisation of microstructure has not been broadly applied to pearlitic steels because of their complex microstructures. Therefore, the characterisation of this morphology becomes inevitable, in order to identify potential weaknesses in the matrix. In this study, hot-rolled reinforcement bars (rebars) produced from recycled steel and direct reduced iron (DRI), were used for microstructural examination using standard metallurgical procedures. Although the optical microscope (OM) and scanning electron microscope (SEM) were used to obtain qualitative microstructure, they could not characterise the pearlite morphology quantitatively because of their three-dimensional (3D) limitation. Hence, the image analyser - Gwyddion Software, was used to quantify the pearlite morphology of these Y16 rebars. The results indicate that the pearlite colony is characterised by 3D single interpenetrating crystals of ferrite and cementite running parallel to each other due to their common growth during the transformation process of austenite. It was further observed that, the dimensional properties of the phases in the morphology in terms of their width and Interlamellar spacing (S), including the roughness of the pearlite colony can vary significantly. These results could be used to enhance the processing methodology of the industrial production processes.

COMPARATIVE STUDY ON STABILITY OF WELDED AND HOT-ROLLED Q420 L300×30 COLUMNS. The Hong Kong Institute of Steel Construction, 2022. http://dx.doi.org/10.18057/icass2020.p.255.

Abstract:
More heavy latticed steel transmission towers are being proposed and constructed in response to the increasing power demand of the rapid developments in China; new steel sections, Q420 L300×30 equal-leg angles, both welded and hot-rolled, are now available in the market. However, previous studies focused less on these large angles and their stability; corresponding design methods were also insufficient. Thus, this research aims to reveal the residual stress distributions and the axial-loaded behaviors of the L300×30 columns, in which sectioning method and FEM analysis were used. The stress distribution models of the welded L300×30 (WL30) and the hot-rolled L300×30 (RL30) sections were compared. Several φ-λ curves in the strong and weak axes were calculated with ABAQUS and compared with the Chinese and European design codes. While axially loaded, it is found that the WL30 columns, which have tensile residual stress at the heel and the toes, are stronger in both axes than the RL30 columns; selections of the design column curves were recommended.

FATIGUE BEHAVIOUR OF TITANIUM-CLAD BIMETALLIC STEEL PLATE WITH DIFFERENT INTERFACIAL CONDITIONS. The Hong Kong Institute of Steel Construction, 2022. http://dx.doi.org/10.18057/icass2020.p.273.

Full text
Abstract:
Titanium-clad (TC) bimetallic steel is a type of high-performance steel, with high corrosion resistance attributed to the titanium alloy and economy as well as excellent mechanical properties resulted from structural steel. Such advanced bimetallic steel is suitable for marine structures, bridges, and buildings exposed to the highly corrosive environment. This paper aims to clarify the high cycle fatigue properties of the hot-rolled TC bimetallic steel with two interface shear strengths of 40MPa and 140MPa. Their stress-strain curves were obtained by the tensile coupon tests. The fatigue S-N curves of TC bimetallic steel at a stress ratio of 0.1 are introduced, which show excellent fatigue performance compared with structural steel. In addition, the hot-rolled TC bimetallic steel with 140 MPa interface shear strength has 21% improvement in fatigue performance than the other one. Despite this, the influence of the interfacial conditions on the high cycle fatigue performance is generally limited. Finally, the S-N curves suitable for these two kinds of TC bimetallic steel are suggested. The research outcomes can provide a reference for understanding the fatigue behaviour of the TC bimetallic steel and the selection of different interfacial conditions in structural engineering
