The invention relates to a branch iron runner castable material. The branch iron runner castable material comprises a main material and an additive. The main material comprises, by weight, 5-8 parts of magnesium titanate with particle sizes of 3-5mm, 15-20 parts of chromium nitride with particle sizes of 5-3mm, 15-20 parts of sillimanite with particle sizes of 3-1mm, 8-15 parts of calcium chromite with particle sizes of 1-0mm, 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 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 iron magnesium oxide powder, 1-3 parts of Rho alumina and 1-5 parts of fused pure calcium aluminate cement. Based on the total weight part of the above main materials, a weight part of calcium lignin sulphonate is 0.1-0.2, a weight part of nanometer potato powder is 0.01-0.05, a weight part of malic acid is 0.01 and a weight part of C12H14N4O5S2 is 0.1. A blast furnace iron runner prepared from the castable material has the characteristics of good thermal shock resistance, corrosion resistance, large iron influx and long service life.
