Homogenized material-containing blast furnace tapping yard branch channel castable and preparation method thereof
The invention discloses a homogenized material-containing blast furnace tapping yard branch channel castable and a preparation method thereof, and belongs to the technical field of blast furnace smelting high temperature refractory materials. The castable comprises the following raw materials, 20-25wt% of a homogenized material with the particle size of greater than 5mm and not greater than 8mm, 10-20wt% of a homogenized material with the particle size of greater than 3mm and not greater than 5mm, 5-15wt% of a homogenized material with the particle size of greater than 1mm and not greater than 3mm, 10-15wt% of a homogenized material with the particle size of greater than 0.088mm and not greater than 1mm, 5-15wt% of homogenized material fine powder with the particle size of not greater than 0.088mm, 10-15wt% of 90 silicon carbide, 2-5wt% of pure calcium aluminate cement, 0-10wt% of alumina micro-powder, 1-5wt% of silicon micro-powder, 1-3wt% of a composite carbon material and 1-3wt% of an antioxidant, and also comprises 0.2-0.3wt% of an additive. The castable has the advantages of good construction performance, good erosion resistance, prolonged service life and cost reduction.
