Features: castable for blast furnace runner is composed of corundum or high alumina clinker as the main raw material and reasonable additives .It can be directly poured or prefabricated.It is mainly used for lining of iron channel material of blast furnace.It has the following advantages:
1.Strong resistance to erosion and erosion of molten iron and slag;
2.Less water,good fluidity,anti burst,and quick baking;
3.Strong thermal shock resistance and volume stability.
