Casting-molded aluminum-silicon lightweight refractory material
The invention belongs to the technical field of refractory materials, and discloses a casting-molded aluminum-silicon lightweight refractory material which comprises raw materials and solvents, wherein the raw materials comprise ceramic powder as base packing; the solvent comprises water, a thickening agent and a dispersing agent; the raw material of the aluminum-silicon lightweight refractory materials further comprise pure calcium aluminate cement and ceramic fiber for improving the strength and the thermal shock resistance of a product; the solvent further comprise silica sol; the pure calcium aluminate cement and the silica sol act together to complete the hardening process of the refractory material; when the refractory material is hardened, the pure calcium aluminate cement is hydrated and hardened in a solvent and acts with the silica sol to form the framework of the lightweight refractory material, and the ceramic powder and water molecules can be adhered to the framework of the lightweight refractory material. The casting-molded aluminum-silicon lightweight refractory material has the characteristics of fine aperture, uniformity in distribution, good thermal insulation property, high strength, good erosion resistance and good washout resistance.
