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.
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.
Monolithic castables for ladle safety lining are composed of corundum, high quality bauxite, superfine powder and other ingredients and featured with good work ability on site casting, high strength, high volume stability and long life span.
