Characteristic & Application

Product features:

1.heavy material density is good, high compressive strength, corrosion resistance to various corrosive gases, good thermal shock stability, excellent thermal conductivity, wear resistance.

2.the internal structure of the lightweight material is uniform, high compressive strength, corrosion resistance, heat shock resistance, oxidation resistance, high temperature, low thermal conductivity.
 

Typical applications:
Mainly used in petrochemical industry, large and medium-sized synthetic ammonia gasifier and magnetic material gas furnace materials, high temperature industrial kiln supporting facilities materials.
Hot surface lining materials for industrial furnaces, such as annealing furnaces, carbonizing furnaces, tempering furnaces, oil refining furnaces, cracking furnaces, roller furnaces, tunnel furnaces, etc.; Industrial furnace backing insulation materials, such as glass tank kiln; Reductive atmosphere furnace.
