The refractories of corundum mullite bricks of Jinma charging material are relatively high and can reach above 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 bricks is larger than that of sintered mullite.
Corundum castables are more expensive than ordinary castables because of their relatively high aluminum content, but good products can be used for a long time, just like corundum castables, which are longer than other castables because of their high aluminum content.However, we often see two kinds of corundum castables, one is corundum high strength and wear-resistant castable, one is corundum mullite high strength and wear-resistant refractory castables, and the two castables that appear to contain corundum are very different in performance. What is the difference between corundum and corundum mullite?Corundum firebrick, chrome corundum firebrick and titanium corundum fire resistant.
Gongyi Jinma furnace Material Co., Ltd. is a new type of private enterprise, mainly including alumina hollow ball bricks, corundum mullite bricks, white corundum bricks, silicon carbide bricks, alumina hollow ball castables, zirconia bricks and other refractory products.Our company has continuously innovating and developing new products, mainly used in metallurgy, chemical industry, ceramics, building materials, power and other industries, and has achieved satisfactory results.White corundum brick is a medium and high-grade refractory material. Its color is white and crystal. The white corundum brick has the advantages of large volume density and low porosity. It can effectively improve the volume stability and thermal shock resistance of the material.Fused white corundum is produced in middle and high grade.
