摘　　要：为了减少转炉下渣量,莱钢在分析借鉴国内外下渣控制技术的基础上,采用红外下渣检测+自动滑动水口开闭挡渣方式,挡渣成功率达到100%,平均下渣厚度仅为32mm,出钢滑动水口挡渣后LF精炼平均回磷量只有0.0014%,同时减少了精炼扩散脱氧剂用量,提高了精炼节奏。In order to reduce the amount of converter slag, based on analyzing and profiting from the domestic and foreign control technologies of slag stopping, Laiwu Steel adopted infrared slag detection and the slag stopping mean of auto sliding gate opening and closing. The success rate of slag stopping reached 100% and the average thickness of slag carry-over was only 32 mm. After slag stopping by it, the average rephosphorization in LF refinement was only 0.001 4%, while reducing the amount of the deoxidation reagents and improving refining rhythm.
