The high-strength alkali-resistant refractory castable has good resistance to alkaline gas and slag, and has a long service life. High strength alkali resistant castable is mainly used for lining of other industrial furnaces such as kiln door cover, decomposition furnace, preheater system and pipeline system.
The silica mullite firebrick produced by our company is made from high-grade bauxite clinker and high-quality silicon carbide as the main raw materials and firing at high temperature.
The manufacturing technique of phosphate refractory bricks is same as phosphate castable. With rapid development recent years, phosphate refractory brick is remarkably effective in cement kiln and electric furnace roof.
Corundum mullite firebrick uses corundum and mullite as aggregate and fine powder, adding appropriate additives. Corundum mullite fireproof brick is formed by high-pressure and sintered at medium-temperature through reasonable process ratio.
The appropriative refractory castable for tertiary air duct has the characteristics of high strength, good wear resistance, erosion resistance, erosion resistance and no cracking.
The alkali-resistant firebricks use silica, coke stones and appropriate additives to improve the microstructure of the product.
