  • Inquiry
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.
It is not only resist high temperature, but also preserve 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.
