在固定武汉钢铁有限公司二炼钢厂转炉白云石加入量与加入方式的条件下,对比了半自动炼钢与手动炼钢对钢水C,Mn,Si,P,S的影响,结果表明,半自动炼钢条件下使用白云石造渣能够满足钢种成分要求,其中钢水C,Mn,P成分相比手动炼钢波动性小,重现率高,而钢水Si、S成分主要受入炉铁水成分影响,与操作方式无关。
The effect of semi-automatic steel-making and manual steel-making on C, Mn, Si, P and S in molten steel was compared under the condition of adding dolomite and adding method of converter dolomite in the second steelmaking plant of Wuhan Iron and Steel Co., Ltd. The results showed that semi- The use of dolomite slagging in steel can meet the requirements of steel composition. The steel C, Mn and P have less volatility and higher reproducibility than manual steelmaking. However, the contents of Si and S in molten steel are mainly affected by the composition of hot metal, Mode of operation has nothing to do.
