The invention relates to castable. The castable is prepared from a main material and additives. The main material is prepared from, by weight, 5-8 parts of 8-5 mm barium aluminate, 15-20 parts of 5-3 mm chromium mononitride, 10-15 parts of 3-1 mm sillimanite, 8-15 parts of 1-0 mm calcium chromite, 2-5 parts of clay-like powder, 3-7 parts of cobalt aluminum oxide powder, 5-10 parts of cutting powder, 3-8 parts of amorphous graphite, 1-2 parts of composite powdered carbon, 0-3 parts of molybdenum trioxide powder, 3-5 parts of alumina micro powder, 1-5 parts of magnesium oxide iron powder, 1-3 parts of rho aluminum oxide and 0-5 parts of electric-smelted pure calcium aluminate cement. With the main material accounting for 100% by weight in total, the additives are prepared from, by weight, 0.1-0.2 part of calcium lignosulfonate, 0.01-0.05 part of nanometer dried potato powder, 0.01 part of malic acid and 0.01 part of C12H14N4O5S2. A blast furnace iron runner made of the castable has the advantages of being good in thermal shock resistance, high in corrosion resisting performance, large in iron exchanging amount and long in service life.
