Products Description
NBSiC refractory products feature excellent high-temperature strength, wear resistance, and corrosion resistance.
They can be used as kiln shelves, setter plates, flame baffles, H-kiln furniture, and various custom-shaped components with outstanding resistance to high temperature, wear, and corrosion. They are also applied in high-speed kiln burners, metallurgical blast furnace linings, and aluminum electrolytic cell linings.
These products are widely used in sanitary ceramics, daily-use ceramics, electrical insulators, magnetic materials, grinding wheels, industrial kilns, pumps, boilers, power plant environmental protection systems, as well as industries such as petroleum, metallurgy, chemical engineering, and aerospace
