[0107] To produce a certain steel grade, the sulfur requirement for the steel grade is S 钢种成品硫含量% is 0.0125%, converter end point sulfur requirement S 转炉终点硫含量 % is 0.0095%, S 转炉回硫量 % is 0.003% to 0.006%. Current heat S 铁水初始硫 % is 0.025%, the sulfur content in steel scrap (S 废钢硫含量 %) is 0.025%, scrap weight (M 废钢重量 ) is 38 tons, the weight of molten iron (M 铁水重量 ) is 252 tons, the mass percentage of sulfur in molten iron slag (S 高炉渣硫含量 %) is 0.9%, the ladle area is the internal molten iron surface area of the ladle (S 铁水包面积 ) is 15.2m 2 , to measure the thickness of molten iron slag of the current heat (h 渣厚 ) is 0.06m, the density of molten iron slag (ρ 铁水渣密度 ) is 2.0t / m 3 , A 钢水收得率 Value 95%, A 转炉脱硫效率 The value of % is 20%, X 带铁系数 The value range is 0.2 to 0.5.
[0108] 1. Determine the proportion of slag remaining under different initial sulfur conditions: first, determine the S 风险预留 % = 0.003%. Thirdly, calculate the sulfur return amount S in the converter...
