Sunrise Refractory Materials Analysis of Hot Products Mullite Brick

Mullite refractory bricks and corundum mullite bricks have the advantages of high load softening temperature, low temperature creep rate and good thermal shock resistance. They are widely used in blast furnace hot blast stoves, glass melting furnaces, coke quenching and heating furnaces. On the kiln. Mullite refractory refractory bricks are easily eroded by alkaline refractory bricks at high temperatures. In addition, at high temperatures, mullite can be damaged by the reaction of water vapor to form Al2O3.

 

Manufacturing Process of Zircon Mullite Brick

 

Zirconium mulite fire brick selectes high quality mullite sand and zircon powder as its main raw material. Molded by high pressure and sintered by high temperature, the zirconium mulite firebrick has such advantages as high bulk density, high strength, good thermal shock resistance, high temperature erosion resistance and good slag resistance. zircon mulite blocks is mainly used in long-life orifice rings, tank bottom, tank superstructure, perfume bottle feeder, covers for working tanks and soda lime glass.

Classification of Zircon Mullite Brick

1.Zirconium fire mullite made of industrial alumina and zircon

2.Zirconium fire mullite made of high alumina bauxite and zircon

3.Fused granules combined with zirconium mullite firebricks

 

In addition to mullite and its composite refractory refractory bricks with corundum, mullite can also be used with other materials to form refractory bricks to enhance its properties, such as zirconium mullite refractory bricks, mullite-silicon carbide refractory bricks, and the like. The so-called zirconium mullite refractory brick is a mullite-zirconia composite material. However, due to the high price of zirconia, zirconium mullite clinker or refractory brick is often produced by reacting Al2O3 or alumina with zircon in actual production.
