摘要: 以某厂100t转炉生产实践为例,从降低成本角度,研究了转炉原辅料结构的优化。并通过调整铁水废钢比,优化造渣、吹炼工艺,避免了原辅料变化对转炉终点控制的影响,保证了转炉终点C、P的成分控制以及温度控制,降低了钢水的氧化性,转炉钢铁料消耗降低4.78kg/t,终点钢水碳氧积降低至0.0027左右,减少了综合铝耗1.31kg/t。

Abstract: In order to reduce the production cost, the raw material structure was optimized on 100t converter in some plant. The influence of raw material structure change on end point control of converter was avoided through adjusting the hot metal scrap ratio, optimization of slagging and smelting process. The mass fractions of carbon and phosphorus and temperature at end point were controlled, and the oxidization of molten steel was reduced. The ferrous charge consumption in the converter was decreased by 4.87 kg/t, and the carbon-oxygen equilibrium of molten steel at end point was decreased to 0.0027 or so, and the consumption of aluminum was decreased by 1.31 kg/t.

Key words: converter, charge structure, blowing process, optimization
