Quick Details
Specifications
Silica Insulating Brick
CUNSE has world-class silica insulating bricks with low bulk density, low thermal conductivity, high apparent porosity. It is made of crystal silica as raw material by adding into compound flammable substance.
Features:
It not only resists high temperature, but also preserves heat. As the main energy-saving materials of blast furnace, our silica insulating brick can reduce 40%-90% thermal storage and heat radiation loss.
Application:
It is widely available for heat-insulating layer of various of high temperature furnace equipments not in contact with molten slag under high temperature condition(≤1500℃), especially for discontinuous working thermal equipment.
