一、电炉情况我厂以镍磷铁等作为原料,在平炉中加熔剂河沙吹炼成含镍65%左右的一次合金,经电炉继续吹炼并铸成含镍80%以上的镍阳极板。阳极板经硫酸电溶造液,净化除铁、铜、钙等杂质后,浓缩制成特级六水结晶硫酸镍。从1975年以来,我们先后改变了电炉炉衬的结构材料和吹炼渣型,用石英砂水玻璃和耐 First, the furnace situation Nippon-iron and other raw materials, in the open hearth furnace flux melt into a nickel-containing alloy about 65%, continue to blow through the electric furnace and cast nickel over 80% of nickel anode plate . The anode plate is electrolyzed by sulfuric acid to purify iron, copper, calcium and other impurities, then concentrated to make super-grade hexahydrate crystal nickel sulfate. Since 1975, we have changed the structure of the furnace lining material and blowing slag type, with quartz sand water glass and resistance
