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... 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。 展开更多

The lattice structure of filters in residuated lattice was established. It is proved that the set of all filters forms a distributive lattice. Also, the concept of prime filter in residuated lattice was proposed and some equivalent conditions about prime filter were given. 展开更多
