摘要
国内硅热还原法炼镁品质总体仍有提高空间,原生镁锭中硅、铝、锰、铁杂质元素含量均处于不同程度超标情况,几乎都达不到Mg9995以上高纯镁成分。本文拟通过在还原系统中增加还原罐结晶过滤器、添加特殊精练剂,并对生产工艺全过程进行有效控制,实现一步法生产高纯镁。
The quality of domestic smelting magnesium by silicon thermal process is not ideal overall, the primary magnesium ingot usually contains some impurity elements, such as sihcon, aluminum, manganese and iron, the content of them is frequently over standard in varying degees, all the high purity magnesium cant reach the content requirements of Mg9995. In this paper smelting high purity magnesium by one - step method is realized by adding reduction jar filter crystallizer and special refining agent in reduction system and has effective control of the whole production process.
