Clay bricks are dense shaped refractory material. with high refractoriness and mechanical behavior under high temperature, refractory bricks is the necessary material of high-temperature services, mainly used for industrial furnaces and kinls and several thermal equipments.
General Information:
Fireclay bricks are made from clinker clay by mixing, forming, drying, sintering and machining. The Al2O3 content ranges from 36% to 42%.
Fireclay bricks feature stable mechanical strength and good thermal shock resistance, withstanding high temperature up to 1750.
They are commonly applied as refractory lining directly exposed to heat or backup insulation layer in all kinds of industrial kiln or laboratory furnace.

Non standard sizes and shapes are available upon request
Application:
Petrochemical process heater
Heat treatment furnace
Ceramic firing kiln
Cement rotary kiln
Glass melting tank
Backup insulation
