The lightweight high-strength wear-resistant composite brick is based on the silica-mullite brick, with a high-strength lightweight composite layer introduced, followed by high-pressure forming and high-temperature firing.
The product not only has high strength and good thermal shock resistance but also low overall thermal conductivity; it is an energy-saving refractory for cement kilns and lime kilns.
