摘要
泰钢炼钢厂SPHC钢种转炉直上工艺存在浇注过程中间包下水口絮流、连浇炉数偏低的问题。通过稳定钢水酸溶铝含量,实施钢包渣洗工艺,优化钢包吹氩模型,SPHC钢转炉直上连续浇注炉数由平均11炉提高到25炉,优化效果显著。
In the direct casting process of the SPHC after converter smelting in Taishan Steel Group, due to pouring box flocculating flow in nozzle, the number of continuous casting heats is low. Through stabilization of acid-soluble aluminum content, implement of ladle slag washing process and optimization of the ladle argon blowing model, the heat number of continuous casting is increased from 11 to 25. The effect of optimization is remarkable.
