Fire Clay Brick High Refractoriness under Load High Alumina
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.
It is widely used in insulating layers of various of thermal
processing equipments, such as hot blast furnace, coke oven, glass
