Unshaped refractories for tap ditches mainly include ramming materials, castable materials, precast blocks and other unshaped refractories, mainly made of Al203-- SiC-C.

Iron ditch castable is a kind of refractory material for blast furnace iron ditch, and it is also a refractory castable for iron storage type iron ditch. Iron ditch castable is fused corundum, bauxite clinker, graphite and silicon carbide as the main raw materials, with the addition of anti-oxidant, the use of low.

Cement bonded aluminum silicon carbide carbon castable. Iron ditch castable has the characteristics of high strength, good corrosion resistance, good oxidation resistance, erosion resistance and high iron flow. The iron ditch castable is integrally poured into the iron ditch lining, which can be used continuously for a long time, has low consumption of iron resistant materials per ton, does not need short-term maintenance, reduces labor intensity of workers, reduces iron ditch maintenance accidents, and is suitable for medium and large iron-making blast furnaces.
