Abstract (sommario):
Two models able to predict Time-Temperature-Transformation (TTT) diagrams for liquid oxides and oxyfluorides have been developed. One on the basis of the Johnson-Mehl-Avrami-Kolmogorov (JMAK) equation and the other – using Classical Nucleation Theory (CNT). The most recent FactSage database was used for calculating the thermodynamic properties of the liquid and solid phases. The model based on the JMAK equation provided much better agreement with experimental data than the CNT model. The model developed in this study was used to successfully predict TTT diagrams for binary, ternary and multico

Abstract (sommario):
Abstract Composition Adjustment by Sealed argon bubbling – Oxygen Blowing (CAS-OB) process is a ladle treatment process that was developed for chemical heating and alloying of steel. The main stages of the process are heating, (possible) alloying and reduction of slag. The CAS-OB process aims for homogenization and control of the composition and temperature of steel. In this dissertation, a mathematical reaction model was developed for the slag reduction stage of the CAS-OB process. Slag reduction is carried out by applying vigorous bottom stirring from porous plugs at the bottom of the ladle.

Abstract (sommario):
The objective of this research work was to develop a methodology for experimentally estimating the interfacial properties at slag-metal interfaces. From previous experiments carried out in the division, it was decided to use surface active elements like sulfur or oxygen to trace any motion at the interface. For this purpose the following experimental investigations were carried out. Firstly the density of slag was estimated using the Archimedes Principle and the Sessile Drop technique. The density of the slag would give the molten slag height required for the surface active element to travel b

Abstract (sommario):
During the pyrometallurgical extraction of copper, a significant part of the copper is lost with discard slag, which decreases profits, overall copper recovery, and efficiency of raw material usage. Smelting furnace slag usually has a copper content that is close to or higher than that of copper ores. The investigation of copper losses to slag is thus a task of practical significance, as the ore grades are depleting. Slag cleaning, e.g., a settling furnace, can reduce copper losses to slag as the mechanically suspended copper-containing droplets separate from slag under the action of gravity a

A 1/12 scale tank was constructed to physically simulate the metallurgical skimming process in order to gain a better insight of the skimming of fluid slag from copper anode furnaces. 1-decanol and water were used to represent the slag and the underlying liquid metal respectively. It was observed that slag skimming was comprised of two steps, a transportation step to carry slag to the skimming lip, and a removal step to move the slag across the lip. The efficiency of the transportation by bath surface circulation was strongly affected by the method of creation of the surface movement. Submerge

Iron and steel production is a rapidly growing industry with global outputs increasing 65% over the last ten years (World Steel Association, 2012).

In this thesis, alkali activation of fayalite slag was investigated.

The need for a reduction in overall waste output as well as the cementitious properties exhibited by this slag motivated this study. The literature section of this research provides an insight on the previous work in the area of geopolymerization, the source materials used, the activators employed as well as the properties exhibited by various geopolymer products.

The work presented here focuses on the impact of slag composition on the resistance of slag composite cements exposed to sulfates. Such composite systems can be an effective way to provide better sulfate resistance of the binder. However, the differing composition and hydration kinetics between slag and cement results in a change in the phases present and their quantities, the effect of which is often overlooked when assessing their sulfate resistance. Rather, the composition of the slag is typically considered. Compared to cement, slags are richer in Si, Al and Mg, but poorer in Ca. Blended w

The present work deals with some aspects of slags related to secondary metallurgy in the steelmaking process. More specifically the focus is given to sulfur and nitrogen in ladle slags. Even though slags have been fairly well-researched in the past, the available data for these elements in typical ladle slag compositions is rather scarce. In some cases the available data is in discordance. There are also inconsistencies between the literature data and what is commonly observed in the industrial processes.

The wide variability in the use of GGBS as a SCM in different climates, coupled with differences in chemical composition, is bound to have impact on the performance of slag blends.

The stable trench is then backfilled with a mixture of soil and slurry having a consistency of high slump concrete.

Abstract (sommario):
Zinc slag fuming is a kinetically controlled process based on the direct reduction of slag by entrained coal. The kinetics of the process are governed primarily by two factors: (1) the fraction of coal entrained in the slag, and (2) the rate of ferrous iron oxidation. A series of high-pressure coal injection trials have been completed at Cominco's lead smelter in Trail, British Columbia in order to facilitate increased coal entrainment. Fuming rates were increased substantially and over-all efficiencies were improved. These results are in direct contradiction to the predictions of models b

Background and objective: Removal of boron is one of the main challenges in the purification of metallurgical grade silicon (MG-Si) for solar cells and a simple low cost method is therefore needed. Boron removal by slag treatment is today regarded as the most promising method, but the efficiency of the refining method is relatively low. Slag refining as a method for boron removal can be improved by optimization of the slag composition by changing the components and/or the composition of the slag. Another method for improving the slag refining efficiency is to remove boron containing species fr

Under the conditions of 3 different fineness modulous of offshore sand,5 different slag substitutes,1 slump and 4 different water-cement ratios, properties such as workability,compressive strength,tensile strength,durability,diffusibility,elapsing

Abstract (sommario):
abstract: Alkali-activated aluminosilicates, commonly known as "geopolymers", are being increasingly studied as a potential replacement for Portland cement. These binders use an alkaline activator, typically alkali silicates, alkali hydroxides or a combination of both along with a silica-and-alumina rich material, such as fly ash or slag, to form a final product with properties comparable to or better than those of ordinary Portland cement. The kinetics of alkali activation is highly dependent on the chemical composition of the binder material and the activator concentration. The influence of

Abstract (sommario):
Generation of wastes in the form of liquid, solid or gas is inevitable in any industry.Industrial Solid Waste is the waste that is generated from an industrial or manufacturing process and includes the waste generated from non-manufacturing activities as well.Most of these wastes fall under the category of Ashes, Slagsor Sludges. For the present work, three types of secondary lead slag, two types of granulated blast furnace slag (GBS) or iron slag and four types of steel slags were procured and studied.An elaborate study on various characteristics of the slags has been performed.
