The invention relates to refractory castable. The castable comprises a main material and additives. The main material is prepared from, by weight, 5-8 parts of barium aluminate with granularity of 5-8 mm, 15-20 parts of chromium nitride with granularity of 3-5 mm, 10-15 parts of andalusite with granularity of 1-3 mm, 8-15 parts of calcium chromate with granularity of 0-1 mm, 2-5 parts of partial clay powder, 3-7 parts of cobaltous oxide aluminum powder, 5-10 parts of cutting powder, 3-8 parts of earthy 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 oxide iron powder, 1-3 parts of rho-alumina and 0-5 parts of electric smelting pure calcium aluminate cement. With the total weight parts of the main material being 100 parts, the additives are prepared from, by weight, 0.1-0.2 part of calcium lignosulphonate, 0.01-0.05 part of nanometer potato powder, 0.01 part of malic acid and 0.1 part of C12H14N4O5S2. A blast furnace iron groove prepared from the castable has the advantages of being high in thermal seismic resistance, high in corrosion resistance, large in iron exchange amount and long in service life.
