摘　　要：对“留渣+双渣”冶炼工艺的热力学条件进行了计算分析。计算表明,脱磷期温度在1360~1410℃之间,碱度在1.6~1.7之间,TFe含量在15%~20%之间最利于“留渣+双渣”工艺转炉脱磷。经现场实际试验表明该工艺能够降低炼钢渣料的消耗,减少渣量,进而降低炼钢工序成本。The thermodynamic conditions of the"residue residue+double slag"smelting process are calculated and analyzed.The calculation shows that the dephosphorization period temperature is 1360~1410℃,the alkalinity is 1.6~1.7,and the TFe content is 15%~20%,it is most beneficial to dephosphorization of the“retaining slag+double slag”process converter.The actual experiments on site show that the process can reduce the consumption of steel slag and the amount of slag,thus reduce the cost of steelmaking process.
