Product Description
The Description:
Zirconium mullite brick: Based on high bauxite, industrial aluminum oxide powder, sand and a small amount of flux Na 20, CaO, according to a certain chemical composition, the batching calculation (the compound should have appropriate particle composition) and after mixing, molding, drying, pre-burning, crushing and other processes, put into the three-phase arc furnace melting, and then after pouring, annealing, quality inspection, and obtained products. The system has the advantages of high mechanical properties, dense structure, low porosity and high softening degree under load. In addition to widely used in glass melting kilns.

Characteristics of zirconium mullite brick:
1. Resistance to glass and alkali erosion, anti-erosion
2. High mechanical strength, good thermal shock stability
3. Reburning shrinkage and high temperature creep becomes smaller
4. Dense crystal structure
Zirconium mullites brick application: mainly used for glass melting part of the bottom, cooling part of the bottom, small furnace, regenerator cell lattice, L-shaped hanging wall nose area, etc.
It is an indispensable key supporting material for a wide range of applications in large float glass kilns.
Used in large glass kiln melting pool, picture tube kiln, regenerator wall brick and chemical, metallurgical industrial kiln by solution erosion parts.
