摘要
为减少LATS-OB精炼浸渍罩粘渣及提高浸渍罩寿命,分别用CaO-CaF2、CaO-B2O3及Li2O作为钢包渣的调质剂进行调质实验。熔渣半球点法的熔点测试结果表明,采用CaO／CaF2=1或2,CaO／B2O3=1或2和Li2O作调质剂能显著降低钢包渣的熔点;渣-金平衡试验表明,调质后的钢包渣可使钢中的硫含量进一步降低。
The CaO-CaF2, CaO-B2O3 and Li2O were respectively used as modifying agent adding to ladle slag to decrease slag adhesion of LATS-OB refining immersion cover and increase service life of cover. Test results of melting point of slag measured by hemisphere method showed that using CaO： CaF2 = 1 -2, CaO： B2O3 = 1 - 2 or Li2O as modifying agent could remarkably decrease melting point of ladle slag. And metal-slag equilibrium test indicated that the sulphur content in steel further decreased by ladle slag added modifying agent.
