摘要
试验研究了在铁水预处理脱磷脱硫过程中 ,铁水中氮含量的变化规律。结果表明 ,铁水中的氮含量与脱磷粉剂性能和脱碳程度有关 ,铁水中的氮含量与碳含量呈线性关系 ,而碳含量与预处理的时间也呈线性关系 ,得到了铁水预处理中脱氮速率与脱碳速率的关系为 d [N]/ dt=19.0 8d [C]/
The experimental study was performed for nitrogen control in hot metal pretreatment The results showed that nitrogen content in hot metal is influenced by dephosphorization fluxes and degree of decarbonization Nitrogen content is in linear relation with carbon content in hot metal, and carbon content is in linear relation with process time The following equation was obtained: d/dt=19 08d/dt
