What material is used for industrial silicon electric furnace?

Selection of graphite tile material for industrial silicon submerged arc furnace. Industrial silicon electricity is obtained by recovering pure silicon dioxide with low ash carbon reductant in carbon-lined submerged arc furnace. Because the iron content of industrial silicon is very low, graphite electrodes and carbon electrodes are generally used in industrial silicon electric furnaces. Industrial silicon submerged arc furnace is an electric heating furnace for smelting industrial silicon products with silica as raw material and charcoal as reducing agent.
