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.
Features of Al2O3-SiC-C Castable:
High temperature stability: It can maintain stable physical and chemical properties at extremely high temperatures and is suitable for use in high temperature environments.
Wear resistance: Due to the presence of silicon carbide, it has extremely high wear resistance and is suitable for parts subject to high-intensity wear, such as furnace bottoms and runners.
Thermal shock resistance: Excellent thermal shock stability, able to withstand rapid changes in temperature, and prevent cracks caused by thermal shock.
Corrosion resistance: It has strong resistance to molten metals, chemically corrosive substances, and other corrosive substances.
Excellent mechanical strength: It maintains good mechanical strength at high temperatures and can withstand high loads and impacts.
