More Information
Summary:The invention discloses a calcium hexaluminate porous heat insulation castable for a water beam and a stand column of a heating furnace, which is formed by mixing castable main materials and a proper amount of additives, and the castable main materials comprise the following raw materials in parts by mass: 63-90 parts of calcium hexaluminate, 3-10 parts of calcined alumina powder, 3-9 parts of activated alumina micro powder and 4-18 parts of calcium aluminate cement raw materials. The sum of the mass parts of the raw materials is 100 parts. The additives comprise a water reducing agent, a mineralizing agent, an air entraining agent and a foam stabilizer. The heat conductivity of the castable is further reduced by utilizing the intrinsic characteristic of low heat conductivity of calcium hexaluminate and micropores formed by an interlaced hexagonal sheet structure of the calcium hexaluminate and forming pores through an air entraining agent; the problems that an existing heavy aluminum-silicon refractory casta
