The invention relates to iron trough castable. The castable comprises a main material and additives, wherein the main material is prepared from, by weight, 5-8 parts of 5-8 mm barium aluminate, 15-20 parts of 3-5 mm barium aluminate, 10-15 parts of 1-3 mm andalusite, 8-15 parts of 0-1 mm calcium chromite, 2-5 parts of partical 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 aluminum oxide micro powder, 1-5 parts of magnesium oxide powder, 1-3 parts of rho-aluminum oxide, and 0-5 parts of electric smelted pure calcium aluminate cement; based on the fact that the total weight part of the main material is 100%, 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 C<12>H<14>N<4>O<5>S<2>. A blast furnace iron trough prepared from the castable has the advantages of being good in thermal shock resistance, great in anti-erosion performance, large in iron exchanging amount and long in service life.
