The product is made by foam quick-setting technique, which is characterized by small bulk density, high CCS , HRUL, small dimension tolerance and good thermal shock resistance. It has the lowest and most stable thermal conductivity in all the types of insulating refractory bricks, which is widely used in insulating layers of all kinds of thermal equipment.It reduces the total weight of furnace body and the thickness of furnace wall effectively,improve heat efficiency,lower energy consumption,improve work conditions, improve production efficiency and considerable economic benefit can be obtained.
