摘　　要：河钢舞钢二炼钢存在严重的炉机不匹配问题。通过对河钢舞钢二炼钢车间布局、工艺流程等方面的系统调研和分析,发现合理安排转炉准备时间,避免浇次内更换水口和滑板,可有效控制转炉周期;增加并稳定出钢量,在恒拉速的情况可有效延长连铸周期,炉机不匹配得到有效缓解;同时,使用"转炉→3#LF→2#VD→连铸"的工艺流程,能耗降低。There is a serious mismatch between BOF and caster in No.2 steelmaking plant of HBIS Wusteel.Based on the systematic investigation and analysis of workshop layout and process flow,it is found that the converter cycle can be effectively controlled by the rational arrangement of the converter preparation time and avoiding the replacement of the water inlet and the skateboard during cast.Increasing and stabilizing tapping quantity can prolong the continuous casting cycle at constant drawing speed and alleviate effectively the mismatch.At the same time,energy consumption is reduced by adopting the process flow of converter→3#LF→2#VD→continuous casting.
