Having an oxygen converter steelmaking method with addition of slag
2015
A method with addition of oxygen steelmaking slag material, the CaO content in the selection of raw materials 53% to 55% limestone, lime CaO content of 90% to 92% and SiO2≤2.5%, light burned dolomite MgO content of 28% to 32% and SiO2≤2.5%, the sludge ball T, Fe content of 52% to 56% iron ore for steel making T, Fe content of 61 to 63%. Slag weight percentage distribution is as follows: 12% to 14% limestone, lime 28% to 30% light burned dolomite 26% to 28% sludge 14% to 16% ball, 15% to 17% iron, division multiple batches to join. By optimizing the present invention with addition of lime, dolomite and other batches of slag, the slag and the end of the optimization process control, reduce splashing and to smoking process, and can significantly reduce the cost of smelting.
