【摘要】 研究了皮江法炼镁工艺过程中影响镁收得率的主要因素.合格的球团,白云石煅后的活性,炉料的配比,还原剂的添加量和种类,还原时间和温度以及真空度和炉料的粉碎粒度对镁收得率有很大影响.找出还原时间和温度的最佳配合点尤其重要.实验结果表明:在温度为1 230℃,还原时间为10 h,还原料比例为1.15的情况下,镁的收得率最高,平均收得率大于75%,与国家精镁标准相比处于一个比较好的水平.通过分析,此工艺生产金属镁经济效益可观.更多还原

【Abstract】 The main factors that influence the yield of magnesium in Pidgeon process are discussed.The study shows that making qualified spheric agglomeration,the activity of incinerated dolomite,the ratio of charging materials,the kind and amount of reductant added,the time and temperature of reducing,vacuum level,and the grain size of charging materials have effects on the yield of magnesium.It are found out The best adaption of reducing time and temperature.The result shows that the yield of magnesium reaches the highest point when the temperature is 1 230 ℃,the reducing time is ten hours and the ratio of charging materials is 1.15.The average yield is more than 75%,a better level than international standard.After analysis,the economic effects is considerable by this way.更多还原
