Product description
High heat resistant bricks is a kind of middle grade Fire brick among the stereotyped products of refractory materials. It belongs to neutral refractory materials and is used in the lining of industrial kilns.
The composition of high heat resistant bricks is aluminum, the production technology is to add high alumina particles in different proportions to high alumina powder, which is formed under high pressure and sintered at high temperature. So CH Refractories dense refractory bricks have high strength and good thermal shock stability.
