摘　　要：本文介绍上钢五厂在20t钢包中进行的109炉喂Ca-Si线工艺试验结果。钢包喂线工艺改善了钢的浇注性能,提高了钙的回收率和夹杂物去除能力及其球化程度,从而改善了钢的力学性能。喂线法与喷粉法相比,成本下降5.8元/t以上。This paper describes the results of 109 heats in Ca-Si wire feeding tests which were carried out in a 20 t ladle at Shanghai No.S Steel works, with the wire feeding process, steel casting performance has been improved, Ca-yield, removal of inclusions and degree of globular inclusions has been increased, thus mechanical properties of steel have been improved. Comparing with powder injection process, production cost of the process is reduced by more than 5.8 yuan/t.
