在毛主席革命路线指引下,我厂革命职工,破除迷信,解放思想,在1000KVA 的小容量电炉上炼出了含矽量达75%的高硅铁,日产量达到二吨以上。按照洋框框,炼高硅铁需要6000KVA 以上的大容量电炉,要求高纯度的原材料。但是,我厂只有一台原用硫酸矿渣冶炼生铁的1000KVA 电炉,焦炭用的是电石生产中筛下的焦
Under the guidance of Chairman Mao’s revolutionary line, our factory revolutionary workers, breaking superstitions and emancipating their minds, refined high ferrosilicon with a silicon content of 75% on a small-capacity electric furnace of 1000KVA and the daily output reached more than two tons. In accordance with the Western frame, refining high-ferrosilicon needs more than 6000KVA large-capacity electric furnace, requiring high-purity raw materials. However, I plant only a former sulfuric acid slag smelting pig iron 1000KVA EAF, coke is used in the production of calcium carbide sieve
