Product Description

Product Description

Common fused mullite is a kind of crystal phase composite refractories,which is made of bauxite as the main raw material,quartz sand and other additives melted in the electric arc furnace and crystallized rapidly.The product has low carbon residue,low porosity,low impurity content,high bending strength,high refractoriness under load,high hardnessm,low high-temperature creep and good crystal development.With its excellent thermal shock resistance and wear resistance.

Application

Low creep hot blast furnace bricks, Sillimanite Bricks, Hot metal torpedo tank lining bricks
High temperature industrial kiln bricks, Glass kiln lining bricks, shed board
Petrochemical industry
For investment casting, for producing refractory materials for steel industry, for producing high-purity mullite glass melting furnace blocks, for kiln furniture and other applications.
Refractory for glass and steel industry
High-purity mullite block, used for hot blast stove in steel industry.
Ceramic kilns petrochemical industry  
Glass lining brick kiln
