Description

1.YAOXING lightweight mullite fire brick is made from high-grade 

and high purity refractory powders and materials.

2. During the process of production, organic and multiple filling materials 

are injected according to the required proportion. 

3.YAOXING mullite brick is compressed in vacuum 

and sintered under high temperature conditions.

 

Application

1.Lining and back lining of various furnaces in the industry of metallurgy, 

petrochemical, ceramics, machinery and building materials.

2.The cracking furnace, conversion furnace, heating equipment, refining 

equipment, reproduction equipment, hot blast stove, heating furnace, even-heating furnace, 

heat-processing furnace,resisitance furnace, tunnel kiln, shuttle kiln, bell-cover kiln, glass-pool-kiln,etc.
