Castable for 2000m<3> blast furnace supporting iron runner
The invention relates to a castable for a 2000m<3> blast furnace supporting iron runner. The castable comprises a main material and an additive, wherein the main material comprises the following components in parts by weight: 5-8 parts of 5mm-8mm zirconium mullite, 15-20 parts of 3mm-5mm chromium nitride, 10-15 parts of 1mm-3mm sillimanite, 8-15 parts of 0-1mm calcium chromate, 2-5 parts of clay powder, 3-7 parts of cobalt aluminum oxide powder, 5-10 parts of cutting powder, 3-8 parts of amorphous graphite powder, 1-2 parts of composite carbon powder, 0-3 parts of molybdenum trioxide powder, 3-5 parts of alumina micro powder, 1-5 parts of magnesium iron oxide powder, 1-3 parts of rho alumina and 0-5 parts of electric-fused pure calcium aluminate cement; the additive comprises the following components in parts by weight of 100% of the main material: 0.1-0.2 part of calcium lignosulphonate, 0.01-0.05 part of nano potato powder, 0.01 part of malic acid and 0.1 part of C12H14N4O5S2. The blast furnace supporting iron runner prepared from the castable has the characteristics of good thermal shock resistance, strong erosion resistance, high iron influx and long service life.
