Mullite Insulation Bricks For Sale

Mullite insulation bricks is a new type of refractory material in China, which can directly contact flame and has the characteristics of high temperature resistance, slightly high thermal conductivity, small energy saving effect and so on. Mullite insulation brick is a high alumina refractory with mullite as the main crystal phase.

Introduction To Mullite Insulation Brick

1. High refractoriness, up to more than 1790℃. The starting temperature of load softening is 1600 ~ 1700℃. The compressive strength is 70 ~ 260MPa at normal temperature.

2. Good thermal shock resistance. There are two kinds of sintered mullite brick and electrofused mullite brick. Sintered mullite brick with high bauxite clinker as the main raw material, adding a small amount of clay or raw bauxite as a binder, through molding, fired and made.

Mullite Insulation Bricks Application

Used for lining of cracking furnace, hot air furnace, ceramic roller kiln, electric porcelain drawer kiln, glass crucible and various electric furnaces. Glass melting kiln superstructure brick, material passage brick, cover plate, metallurgy is very other industry medium temperature kiln furnace lining, carbon black reaction furnace quench section, stay section lining. Lining of upper crown, crown brick and other industrial heating equipment of glass melting kiln. Glass furnace superstructure brick, cover plate, molding parts, medium temperature carbon black reactor and other thermal equipment lining. Mullite and corundum saggers for high temperature. Glass furnace superstructure brick, material path brick, cover plate, molding parts, medium temperature carbon black reaction furnace lining and other thermal equipment lining. Corundum and mullite saggers for high temperature.

The lightweight mullite brick is made of imported plate-shaped corundum and high-purity fused corundum with the application of advanced ultrafine powder adding technology. It is mixed, dried and shaped and fired in a shuttle kiln at high temperature. Mullite light brick is widely used in residue gasifier, second stage reformer of synthetic ammonia, carbon black reactor and refractory furnace. The size of the products, physical and chemical indicators, service life are up to customer requirements.
