用铝渣和石灰对铁水预脱硫的热力学

Thermodynamics of desulphurization with aluminate and lime in the pretreatment of hot metal

    摘要
  • 摘要: 通过热力学计算分析了Al在铁水中与氧和硫反应的平衡活度,当CaO和Al同时加入铁水中,适量的Al会提高CaO的脱硫能力.探讨了在Al的参与下,CaO作为脱硫剂时的脱硫热力学反应机理,以及Al2O3和CaF2对铁水脱硫的作用.

     

    Abstract: The activities of sulfur and oxygen reacted with aluminum in hot metal were calculated by the thermodynamics data. The capability of desulphurization for hot metal could be increased as aluminum and lime were added into hot metal together. In this case, the thermodynamics reaction mechanism of desulphurization and the effect of Al2O3 and CaF2 in desulphurization in hot metal were discussed.
