Fire Clay Brick High Refractoriness under Load High Alumina Insulating Bricks
Features:
1. It has advantages with small bulk density, high cold crushing strength, and high refractoriness under load, small dimension tolerance and good thermal shock resistance.
2. It has the lowest and most stable thermal conductivity in various insulating refractory bricks.
Application:
It is widely used in insulating layers of various of thermal processing equipments, such as hot blast furnace, coke oven, glass kiln, etc.
