Product Description

It is produced by foam coagulation technique.
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.
3. It can reduce the total weight of furnace body and the thickness of furnace wall effectively, improve heat efficiency, lower energy consumption, improve work conditions and production efficiency, and considerable economic benefit can be obtained.
Application:
It is not only widely used in insulating layers of various of thermal processing equipments, such as hot blast furnace, coke oven, glass kiln, etc, but also apply to linings in parts of furnace without strong high-temperature molten material erosive.
