Brand:CUNSE
Model:-
MOQ:10 Metric Ton
It is produced by foam coagulationtechnique.
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.
