摘　　要：文中介绍了碳化硅作为脱氧剂在平炉炼钢中的应用,并与传统的扩散脱氧剂(碳粉、硅铁粉)进行了比较。结果证明,用碳化硅作为平炉炼钢脱氧剂,可提高合金回收率,降低炼钢成本,而且回磷趋势减弱,对钢液增氢、回硫影响不明显。因此,碳化硅作为扩散脱氧剂在平炉上应用是完全可行的。The application of carbofrax as deoxidant in open-hearth steelmaking has been introduced in this paper·By comparison with traditional deoxidant (carbon powder, ferrosilicon powder), the results have been obtained that using carbofrax can increase the recovery rate of alloy, reduce the cost of steelmaking, subside the tendency of rephosphoration to liquid steel and have hardly influence on liquid steel increasing hydrogen and sulphur. So it is practicability that the carbofrax is used in open-hearth steelmaking as deoxidant.
