Description of Al2O3-SiC-C Castable:
Al2O3-SiC-C Castable not only has the characteristics of strong resistance to molten iron, slag erosion and scouring, but also has good thermal shock resistance, good oxidation resistance. It is easy to construct and can be quickly baked without bursting. What is more, it does not stick to iron slag during use, and has a long service life.
