Product description
Low creep high alumina brick 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.This series of alumina silica brick use special grade aluminum bauxite clinker as the main raw material, supplemented by special additives, high pressure forming and high temperature firing. Refractory bricks alumina has the characteristics of large heat storage capacity and small creep rate.
Advantages：
◆ Low creep rate
◆ Large heat storage capacity
◆ Customize mould according to different size requirements for free
◆High strength, good thermal shock resistance, anti-stripping, Free sample, Free construction guidance, free 3D design.
