Fireclay chamotte lining high alumina resistant fireproof heat refractory fire clay brick
Product Description
Laurel high alumina refractory bricks are made of high sintering selected bauxite chamotte by the advanced process with strict quality control. It can be divided into different types according to the content and applications.
The working temperature will increase with higher alumina composition and the products are characterized by resistance to acid slags and good corrosion resistance. They are widely used in glass furnaces, blast furnaces, hot blast stoves, electric arc furnaces, cement kilns, and other thermal equipment.
