硅热法炼镁,是因为可以直接采用分布广泛的白云石资源,能利用多种热源,设备和工艺流程较简单,建厂投资少,投产速度快,非常适合战争时期制镁的要求,所以同时在几个国家里迅速发展起来。但是,当时建设的硅热法炼镁厂,所用还原炉的结构不够完善,大多数是间断操作,设备产能低,劳动条件差,然而战后却引起各国对硅热法炼镁的重规,从工艺 Silicon thermal refining of magnesium, because the direct use of widely distributed dolomite resources, can use a variety of heat sources, equipment and process is relatively simple, less investment in plant, put into operation fast, very suitable for the requirements of magnesium during the war, so At the same time in several countries rapidly developed. However, at that time, the structure of the reduction furnace used in the smelting furnace was not perfect, most of which were intermittent operation, with low production capacity and poor working conditions. However, the post-war countries caused heavy losses on magnesium smelting by thermal refining in silicon, From craft
