Abstract:
The effects of operation parameters on desulphurization of hot metal with passive magnesium and calcium oxide injection in CSP plant of WISCO. have been studied in this paper. On basis of industrial optimization trials’ results on hot metal desulphurization, the original desulphurization process had been modified. Through the new-developed desulphurization process, desulfurizer consumptions have been decreased a lot by 40% with passive magnesium and 34% with lime respectively. Economical profits can be seen from the desulphurization process.

Abstract:
In cognizance of the problems of low desulphurization rate for hot metal, large sulfur-recovery in converter, as well as high sulfur content in products when producing non-oriented electrical steel with vanadium-content hot metal, countermeasures have been carried out. Sulfur content in non-oriented electrical steel is decreased obviously with the study on technologies of desulphurization for hot metal with vanadium & titanium, sulfur-recovery control in converter, and desulphurization in RH refining process as well. The results of industrial tests show that the rate of w(S)≤0.008 % is as

Abstract:
In the conditions of JSC Ural Steel, the most costly technological task in the production of high-quality steel is to provide the required sulfur content. The analysis of the sulfur removal in the production of high-quality steel in the technological conditions of JSC Ural Steel was performed. An increase in the sulfur content of the pig iron at 0,007-0,010% of the tapping from the blast furnace until used in an electric arc furnace was founded. The need for preliminary hot metal desulphurization before pouring in the electric arc furnace was justified. The method of calculating the cost of ho

Application of dispersed reagents in hot metal ladle treatment processes enabled for solving a wide range of tasks of increasing metal products quality and improving technical and economic indices of metal smelting processes. But there are reserves of existing technologies improving, since during their application a whole number of peculiarities of heat- and mass exchange processes, having place in ladle at wide range of parameters and refining conditions, are not taken into consideration. Therefore, elaboration of conceptions about exchange processes mechanisms at different reagents injection

Abstract:
The desulphurization process parameters of vanadium bearing hot metal were optimized. It is found that it has the best desulfurization effect in 100t hot metal ladle, when the lance position is 280mm, the ratio of lime to Mg is 3:1, and the Mg injection rate is 9kg/min. The Si and Ti content of hot metal can increase the activity of S. With the increase of Si and Ti content of hot metal, the final sulfur content has a reduction trend. When the content of Si and Ti is lower than 0.35%, the final sulfur content of hot metal increases, and the hit rate decreases. The effect of hot metal temperatu

Abstract:
Reduction of high-phosphorus titanomagnetite was studied for future comprehensive utilization of resource. Experimental temperature (T), burden alkalinity (CaO/SiO2) and carbon-oxygen ratio (C/O) had an influence on the content of [P] and [S] in hot metal. Highest dephosphorization rate in hot metal appeared at C/O=1, high temperature was beneficial to desulphurization, but not for dephosphorization. High CaO/SiO2may decrease the content of [P] and [S]. C/O and CaO/SiO2had great influence on the content of [P] and [S] in hot metal.

In this thesis work, some basic concepts about desulphurizationof hot metal have been done based on a literature study. Two experimentaltrials have also been carried out to study the slags: one consider as areference and in the other trial, the amount of calcium carbide was reduced by150 kg. The average carbide efficiency has been improved from 21.3% in trial 1 to 26.0% in trail 2. Metaldroplets containing iron oxides are found in three of eight heats and most ofmetal droplets are surrounded by Ti-compounds. The slags mainly consisted of (Ca,O, Si) and (Ca, S), with some low content of other e
