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。 In this paper, the application of silicon carbide as deoxidizer in open hearth steelmaking was introduced and compared with the traditional diffusion deoxidizer (carbon powder, ferrosilicon powder). The results show that using SiC as the open hearth steelmaking deoxidizer can increase the recovery rate of the alloy, reduce the cost of steel making, and the tendency of returning phosphorus is weakened, which has no obvious effect on the hydrogenation and sulfurization of molten steel. Therefore, the use of silicon carbide as a diffusion deoxidizer in a flat oven is completely feasible.
