High-quality and high-strength castable for runner are produced with dense corundum or high-quality bauxite chamotte,Sic as main materials,micro-powder as binder,compound additives. JCG-T1 and JCF-Z1 are bauxite castable for iron line and slag line of runner,meeting requirements of medium-volume blast furnaces,Hot metal through put is more than 180,000Ton.

Remark |
JCG-T1&JCG-Z1are corundum based castable for iron and slag lines of main runner for large-volume blast furnace.
JCF-T1&JCF-Z1are bauxite based castable for iron and slag lines of main runner for middle-volume blast furnace
