矿热炉是熔炼铁合金及电石的电弧炉,采用埋弧操作时,它的容量大,消耗电能多。关于它的工作原理,还有很多值得研究的地方。矿石在矿热炉中的还原过程,分无渣法和有渣法两种,前者如炼硅铁,二步法炼硅铬合金。后者如炼炭素铬铁,硅锰合金等。两者炉内功率的分布均不相同。在无渣法 Submerged arc furnace smelting iron alloy and calcium carbide electric arc furnace, submerged arc operation, its large capacity, more energy consumption. There are many more places to study about how it works. Ore ore in the reduction process in the furnace, sub-slag-free method and there are two slag method, the former such as refining silicon, two-step refining silicon-chromium alloy. The latter, such as carbon ferrochrome, silico-manganese alloys. Both the power distribution in the furnace are not the same. No residue method
