【摘要】 在对RH精炼工艺研究的基础上,探索了高CaO渣系对钢水脱硫作用的规律,研究表明,只要渣系组成合适,获得w(S)<0.005%以下是完全可能的。同时,渣系中碱度、渣指数及渣量等对钢液终点硫有重要影响。更多还原

【Abstract】 Based on the study of RH refining process the law of effects of high CaO slag series on the hot metal desulphurization is explored.Results show that it’s definitely possible to refine the clean steel with(S) <0.005% provided that the constituents of the slag series are appropriate.In the meanwhile other factors such as the basicity of the slag series,slagging index and slag quantity will also have great effects on the end-point sulphur content in steel.更多还原
