High-strength and light refractory aggregate
The invention discloses a production process of high-strength and light refractory aggregate. The high-strength and light refractory aggregate is prepared from main raw materials including, by weight, 60-62 parts of aluminium oxide, 18-20 parts of fused magnesite, 0.5-0.8 part of alpha-Al2O3 nanometer powder with the mass fraction of 99.9%, 0.5 part of perlite micropowder, 0.6-0.9 part of stone micropowder and 0.2 part of sericite, the temperature is kept at 15 DEG C after the main raw materials are evenly ball-milled, 25 parts of Soochow clay, 0.8-1.1 parts of SDBS foaming agents, 0.5 part of sodium tripolyphosphate and 6-6.5 parts of dextrin continue to be added and continue to be evenly stirred to form mixed mud, the prepared mud is poured and formed in a mold, demolding is conducted after natural drying, a dried wet blank is sintered in an electric furnace, sintering is conducted in 3 steps, and the finished product is obtained through furnace cooling. The high-strength and light refractory aggregate is light in mass and high in porosity, strength and water resistance.
