在以前的报告中曾阐明了用Na_2CO_3精炼钢水的脱磷特征。本文叙述的是精炼钢水的脱硫,由于是用氧气吹炼,所以远远不同于只用Na_2CO_3精炼钢水的脱硫,然而用与脱磷相同的方法测定了操作结果。在铝坩埚(Al_2O_3>99％)高频感应炉中熔炼了4公斤钢水。通过水冷喷枪将氧气吹入炉内,并且仅仅在熔炼的开始就把粒状Na_2CO_3加入。当把Na_2CO_3加入后,铝坩埚内就充
In the previous report, the dephosphorization characteristics of molten steel with Na_2CO_3 were clarified. Described in this paper is the desulfurization of molten steel, which is much different from the desulphurization of molten steel using only Na_2CO_3 because it is oxygen-blown. However, the operating results are determined in the same way as dephosphorization. Four kilograms of molten steel was melted in an aluminum crucible (Al 2 O 3> 99%) high frequency induction furnace. Oxygen was blown into the furnace by a water-cooled spray gun, and granular Na 2 CO 3 was added only at the beginning of smelting. When Na_2CO_3 is added, the aluminum crucible is filled
