|---|---|---|---|
The iron runner castable that developed by CH Refractories is low cement Al2O3-SiC-C ramming mass, and self-flowing refractory castable, which divided three levels to meet different sizes of blast furnace iron runner and achieved very good performance.
Applications of Iron Runner Castable:
Different size blast furnace iron runner
Advantages of Iron Runner Castable:
High strength at high temperature
Good thermal shock stability
No cracking with fast baking
Not stick to slag
Long service life and easy to construct
Easy to patch
