Fireclay brick is made from clinker clay by mixing, forming, drying, sintering and matching characterized by good resistance to corrosion and abrasion, good thermal shock resistance, good spelling resistance, high mechanical strength, good volume stability under high temperature.
Application of Fire Clay Brick
Low porosity clay bricks can be applied to steel, nonferrous metals, glass, cement, ceramics, pertrifaction, machinery, boiler, light industry, electric power, war industry and other economic filed, which is the indispensable basic material to ensure above production running and technological development, it plays an incomparable important role in the development of high temperature industrial production.
