Product Description

Product Description

 

Fireclay bricks are alumina silicate refractory with
refractoriness of SK 32-34 and 35-45% alumina. The bricks are
made from various raw materials of fire clay, calcined chamotte,
mullite etc. They are highly resistant to abrasion, spalling ond
corrosion. With low porosity, high strength and good resistance to
thermal spalling, abrasion and creep. They are generally applied
for the linings of Coke Ovens, Glass Furnace, Cement Rotary
Kilns, Lime Kilns, Various incinerators, Reheating Furnaces etc..
