Refractory is commonly distinguished SK34 that manufactured with fireclay brick and chamotte, and high-alumina brick(SK36, 37, 38) which generally use high-purity alumina material. It has very various demand as a product that manufactured with high-quality particle size control of material, high-pressure forming, and high-temperature plasticity.
