引言两步等离子熔炼法金属硅传统上是在埋弧电炉内采用碳热还原石英块的方法生产。以利用等离子进行过程加热和两级封闭反应器为基础的一种新型硅熔炼原理已显现一些优点。对利用这种新型等离子熔炼法进行的以下三项实验,即从砂和木炭熔炼硅;从矿和煤-木炭的混合料熔炼硅以及从铁燧石尾矿、石英和木炭熔炼硅铁的结果作了报告。示于图1上的一个直流等离子枪可很容
Introduction Two-step plasma melting process Metal silicon has traditionally been produced in a submerged arc furnace using a carbon thermal reduction quartz block. A new type of silicon melting principle based on the use of plasma for process heating and two-stage closed reactors has shown some advantages. The following three experiments with this new plasma melting process, smelting silicon from sand and charcoal; smelting silicon from a mix of coal and coal-charcoal and the result of smelting ferrosilicon from iron flint tailings, quartz and charcoal The report. A DC plasma gun as shown in Figure 1 is very flexible
