Insulation Bricks High Temperature IFB Kilnlinings

Insulation bricks are commonly used in electric and gas kilns where there is minimal abrasion against the lining of the kiln This is due to the bricks being lightweight and not very dense 23Grade bricks can withstand a maximum service temperature of 2300 degrees Fahrenheit 26GD 2600 degrees and 28GD 2800 degrees

Thermal Insulation of the Refractory Masonry in

2015123 The hightemperature layer of thermal insulation is comprised of PROMAFORM ®1600 rigid fiber boards two layers each 100 mm thick The temperature conditions for their use are created by installing next to them lightweight mullitecorundum brick whose usage temperature is higher than the maximum temperature to which the refractory is heated

Cryston Cu Max Hot Face Bricks Shapes

202236 Hot Face Bricks The Cryston ® Cu Max material’s enhanced oxidation resistance ensures superior furnace life versus traditional nitride and clay bonded silicon carbide products This increases the chemical resistance to copper oxide and is not wetted by molten copper These properties coupled with its high temperature mechanical strength
