Antioxidant blast furnace iron runner castable and preparation method thereof
The invention discloses an anti-oxidation blast furnace iron runner castable and a preparation method thereof, and relates to the technical field of refractory materials, the anti-oxidation blast furnace iron runner castable comprises the following raw material components in percentage by mass: 10.5-12% of 15-8mm brown aluminum oxide, 14.5-16% of 8-5mm brown aluminum oxide, 10-12% of 5-3mm brown aluminum oxide, 10-11% of 3-1mm brown aluminum oxide, 9-10% of 3-1mm compact aluminum oxide, 4-5% of 1-0mm compact aluminum oxide, 11-13% of 1-0mm silicon carbide and 9-10% of 325-mesh silicon carbide. The invention relates to a high-strength wear-resistant high-strength wear-resistant concrete which comprises the following components in percentage by weight: 4 to 6 percent of aluminum oxide micro powder, 1.5 to 2.5 percent of silicon micro powder, 1 to 1.5 percent of high-alumina cement, 1 to 1.5 percent of rho-Al2O3, 0.5 to 1 percent of andalusite, 2 to 2.5 percent of spherical asphalt, 0.5 to 1 percent of carbon black, 0.2 to 0.4 percent of boron carbide, 0.05 to 0.1 percent of molybdenum strontium powder, 1.5 to 2.5 percent of metal silicon powder, 0.02 to 0.04 percent of metal aluminum powder, 0.04 to 0.07 percent of organic fiber and 0.1 to 0.3 percent of water reducing agent. The iron runner castable has excellent oxidation resistance, the use performance of the iron runner castable can be obviously improved, the service life of the iron runner castable can be obviously prolonged, and the maintenance work intensity of an iron runner is reduced.
