摘　　要：AFC 操作工艺具有较好的动力学和热力学条件,冶金效果得到明显改善。与顶吹法比,磷和硫的分配比提高;钢中氧含量降低 10—300 ppm;渣中 ∑(FeO)降低2.0％—6.0％;终点余锰提高0.015％—0.03％。It has been poved that AFC process applied to 180-t converters inAnshan Iron and Steel Complex can provied favorable kinetic and thermody-namic conditions in operation with metallurgical effects greatly improved. Incomparison with top blowing, the process will not only increase the partitionratios of both phosphorus and sulfur but decrease the oxygen content in steelby 10-300 ppm andΣ(FeO) in slag by 2.0%-6.0%. The manganese content inmolten steel will also be raised by 0.015%-0.03% at the very end of blowingprocess.
