School of Materials Science...) by electromagnetic induction slag melting (EISM). Vacuum melting furnace was used to purify boron in different slag systems. The results show that the removal effect in SiO2-CaO-Al2O3 systems is better than......
转炉冶炼工艺过程中炉渣的岩相研究李建新1,郝旭东1,韩秀丽2,刘丽娜2,仇圣桃0,赵沛2(1.北京市钢铁研究总院连铸中心2.河北理工大学 资源与环境学院,河北唐山 063009)摘 要:不同转炉冶炼工艺对转炉渣的稳定性有较大影响,运用岩相检验的方法分析了不同转炉冶炼工艺和调整脱磷剂成分后转炉渣的岩相结构.通过比较常规工艺与新工艺的岩相结构,发现采用新工艺冶炼,岩相分布更加均匀,而且使用新型脱磷剂后高熔点相减少.转炉渣岩相分析结果为合理改进转炉冶炼工艺和改善转炉渣成分提供了科学依据.关键词:转炉炼钢......
Equilibrium between Slag and Molten Iron in the Direct Alloying of Steel with Nb2O5-Bearing Slag陈伟庆,周荣章,林宗彩摘 要:<正> Equilibrium between slag and molten iron at 1600℃ was investigated for the direct alloying of steel with Nb2O6-bearing slag. The activity of niobium oxide in the slag was measured. The αNb2O5 is in the range of 10-2-10-4. TheδNb2O5......
