摘要
基于生产实践,分析了石灰质量及消耗变化对转炉工艺操作及生产成本的影响。石灰生(过)烧率高,SiO2高,造成有效CaO降低,影响石灰渣化速度,过程返干严重;活性度低导致渣量增加,铁损增加,计算可知,石灰消耗每增加1kg/t,影响生产成本升高1.36元/t。
Based on the process practice, this paper analyzed the effect of lime quality and consumption on process operation and production cost in converter. The high rate of raw and over burning and high SiO2 content in lime caused the lower of effective CaO, influenced the lime residue speed and the process drying badly. The low active degree of the lime caused the increase of slag quantity and iron loss, the results showed the lime consumption increased 1 kg/t, and the production cost increased 1.36 Yuan per ton by calculating.
