Used for blast furnace lining in castable refractory material. It is a kind of containing silicon carbide and carbon of high alumina castable. Trough the castable lining was developed in the late twentieth Century 70 a new unshaped refractory materials, with the iron quantity, long service life, low consumption of refractory material, convenient construction etc...

Trough castables is mainly composed of high alumina, silicon carbide, carbonmaterials and binder prepared.

High alumina raw materials: the use of electric melting or sintering corundum spinel, bauxite clinker in one or two.

Silicon carbide materials: can choose one grade or two grade black silicon carbide.

Carbonaceous materials: the use of asphalt, coke, graphite or electrode powdered..

Binder: the clay, good dispersion of oxides or ultrafine powder and pure calcium aluminate cement.

Technical features: iron trough castable trench lining in repair without dismantling old lining, in the clear old lining surface residue and residual iron can be carried out after repair of casting, the old and the new ditch lining has good binding capacity, compared with the ramming material, waste is reduced by more than 50%, after repeated feeding, the total amount of iron. Up to 30 ~ 1000000t
