At present, the industrial silicon submerged arc furnace production/calcium carbide furnaces/ferrochrome furnaces operation basically adopts manual operation, with high labor intensity and high cost of mineral submerged arc furnaces.
Semi-closed or open-type submerged arc furnaces are quite popular in industrial silicon production with dangerous environment, extremely high temperature on site, high-pollutingwith flue gases.
Life-threatening risks are hidden in manual operations: injury to eyes, burning, mechanical injury, object strike, electric shock and other injury accidents occur from time to time.
