碱性中间包覆盖剂的研究与应用
Research and Application of Basic Tudish Covering Flux
摘要: 通过理论分析、夹杂物含量分析、气体含量监测分析等手段,研究了不同成分中间包覆盖剂对于中合金钢液纯净度的影响规律,结果表明,二元碱度5.0左右的超高碱度覆盖剂应用时,中间包冶金过程夹杂物总量下降最多,[N]含量保持稳定,纯净度最优,是最适合中合金钢的覆盖剂类型。
Abstract:
With methods of theoretical analysis, inclusion content analysis and gas content monitoring anal-ysis, the influence of tundish covering flux with different compositions on the purity of medium alloy steel was studied. The results show that when the ultra-high basicity covering flux with ba-sicity of about 5.0 is applied, the total amount of inclusions in molten steel decreases most, the [N] content keeps stable, and the cleanness is the best type of covering flux for alloy steel.
