The electrode paste produced by our company, after years of research, has continuously improved the product formula, adopted advanced production technology, and is used in the submerged arc furnace. It has low ash content, high strength, high density, low resistivity, good conductivity and heat conductivity, and shows particularly excellent quenching and heating resistance in the submerged arc furnace. The products are widely used in large and medium-sized ferroalloy enterprises and chlor alkali and calcium carbide enterprises * in Inner Mongolia, Guizhou, Hunan, Shanxi and other places. Users generally report that they can effectively prevent electrode soft break, hard break, oxidation bee waist and block falling, reduce electrode paste consumption by 5~10kg/t, increase output by 10~20%, increase current density and strengthen production.
