Heat-insulation refractory brick manufacturing method
The invention discloses a heat-insulation refractory brick manufacturing method and relates to the technical field of manufacturing of refractory materials. The heat-insulation refractory brick manufacturing method includes preparing, by weight, 25-35 parts of calcined bauxite, 30-40 parts of silica powder, 15-20 parts of combined clay and 5-8 parts of calcium aluminate cement, mixing, making blank, drying and baking. Compared with the prior art, the heat-insulation refractory brick manufacturing method is high in compression strength, resistant to high temperature and low in heat conductivity and is good in heat insulation effect as a heat-insulation material of a boiler wall, and the boiler using the heat-insulation refractory brick keeps heat long and energy resource is saved.
