Quick Details
Specifications
The castable is a kind of castable that does not touch molten iron, on the surface, the castable need not high requirement, but it is not. It have to can work at high temperature condition, bear its own gravity downward, resist to the slag erosion and the thermal shock when pouring and releasing iron. Therefore, the technology can not be unidirectional.
