Embodiment 1
[0009] A lightweight heat-insulating refractory castable, which is composed of the following raw materials: fly ash, mullite, alumina hollow spheres, alumina powder, and magnesium carbonate; the weight parts of the above raw materials are: 10 parts of fly ash, Mo 30 parts of stone, 10 parts of alumina hollow spheres, 40 parts of alumina powder, 20 parts of magnesium carbonate. Mullite and alumina hollow spheres are aggregates, and fly ash, alumina powder and magnesium carbonate are the matrix.
Embodiment 2
[0011] A lightweight heat-insulating refractory castable, consisting of the following raw materials: fly ash, mullite, hollow alumina spheres, alumina powder, and magnesium carbonate; the weight parts of the above raw materials are: 20 parts of fly ash, Mo 20 parts of stone, 20 parts of alumina hollow spheres, 30 parts of alumina powder, 30 parts of magnesium carbonate. Mullite and alumina hollow spheres are aggregates, and fly ash, alumina powder and magnesium carbonate are the matrix.
[0012] The alumina hollow spheres in the aggregates of the thermal insulation refractory castables have a special surface structure and are hollow inside, with uneven surfaces, which increase the contact surface area, so that the aggregates are combined with the alumina powder, magnesium carbonate, and fly ash in the matrix It is firm, which not only improves the fire resistance performance, but also increases the strength of the material and the heat preservation effect. Magnesium carbonate dec...
