Jinma burden Corundum mullite brick Refractoriness is high, up to 1790 degrees Celsius. The softening begins at 1600~1700 C. The compressive strength at room temperature is 70 ~ 260MPa. The thermal shock resistance is good. There are two kinds of sintered mullite brick and electric mullite brick. The sintered mullite brick is made of bauxite clinker as the main raw material with small amount of clay or bauxite as binder. The electric melted mullite brick is made of high alumina, industrial alumina and refractory clay as raw materials, and charcoal or coke fines as reducing agents. The crystallization of fused mullite brick is larger than that of sintered mullite, and its thermal shock resistance is better than that of sintered products. Their high temperature performance mainly depends on the content of alumina and the uniformity of mullite phase and glass distribution. It is mainly used in the top of hot blast stove, blast furnace body and furnace bottom, glass furnace regenerator, ceramic sintering kiln, oil cracking system and so on.
   Corundum mullite brick It is made of high purity corundum and fine mullite as raw material by high pressure molding and high temperature firing. The products are characterized by high temperature resistance, corrosion resistance, oxidation resistance, good thermal stability, and small line change rate. They are mainly used in petrochemical industry, large and medium sized synthetic ammonia gasifier and magnetic material gas furnace material, high temperature industrial furnace supporting facilities and so on.
Production of Jinma burden is excellent. Corundum mullite brick We choose better raw materials to produce environmental corundum bricks. Our company has strong technical strength and complete quality assurance system. It adopts the new scientific research results at home and abroad, provides advanced products with advanced production technology, modern enterprise management, and provides better services.
