China is the the largest producer of refractory raw materials in the world, and its magnesite and crystalline graphite reserves are among the top in the world. Over the years, China's high-alumina bauxite export volume also ranks in the forefront of the world. Therefore, the production of refractories materials in our country is conducive to solving the problem of raw materials on the spot. Our company has its own mineral resources, so the price is lower. Welcome to inquire.
