With the features of high strength, high temperature resistance, high preeure resistance, strong acidakali corrosion resistance and good heat shock stability, it is mainly used in high temperature, high pressure and strong corrosion working environment on chemical industry. It's the optimal filler material of reburner, reacting furnace, filler furnace in oil and chemical industries.
