摘要
The paper focuses on an evaluation of the slag regime and steel desulphurisation in a ladle with the help of synthetic slags based on Al2O3 containing various mass amounts of Cr2O3 varying from 0.3 % to 3.0 %. The aim of the plant experiments was to assess the achieved results when using two types of synthetic slag focusing on the course of desulphurisation, an analysis of the achieved chemical composition of the slag and an evaluation of the influence of oxide Cr2O3 on the increase in the chromium amounts in steel during secondary metallurgy. During the evaluation of the slag regime in the ladle, samples of steel from various technological nodes for a determination of the desulphurisation degree and the achieved chromium amounts in steel were taken. Samples of slags for the evaluation of the achieved chemical composition and amounts of Cr2O3 in the slag were also taken. The results mentioned in this paper represent the basic information about the possibilities of applying synthetic slags with increased amounts of Cr2O3 within secondary metallurgy.
