Problems solved by technology

[0004] In addition, during production, lime and coal need to be supplied to the lime kiln and coal carbonization furnace respectively. The ratio of raw materials to make calcium carbide is different, and the amount of lime and coal entering the submerged arc furnace may be different. Most of the existing technologies control the feeding time To control the ratio of lime and coal, this method has large errors, and the production quality of calcium carbide is prone to unevenness; in addition, the electrode part in the submerged arc furnace will be damaged during use, resulting in a decrease in the electric heating efficiency between the electrodes , making the production efficiency of the submerged arc furnace decrease
