本文研究了高炉铝酸钙炉渣的浸出动力学,考察了搅拌强度、浸出反应温度、浸出剂初始浓度以及炉渣粒度对浸出速率的影响。结果表明,浸出过程符合一级反应的收缩未反应核模型,宏观动力学方程为1+2(1-xB)-3(1-xB)2/3=[1.108exp(-1906/T)]t,其表观活化能为15.84KJ/mol。过程速率为固膜内扩散速率控制。通过用实验数据进行验证,表明所得模型能较好地描述炉渣的浸出过程。

研究了采用高岭土型煤矸石为原料,经碳热还原制取的铝硅铁合金为还原剂热还原炼镁的工艺条件。发现,与传统的硅铁还原剂相比,此还原剂具有还原温度低、还原速度快、过量系数小、制团压力低等优点。经初步估算采用此种还原剂,在相同的还原率下,把每日二个生产周期改成每日三个生产周期是完全可能的。若如此,在镁的产量可增加产品产量约1/3的同时,镁的成本约降低1680元/吨镁左右。
