Ceramic fiber sealing ring is used for sealing products used when the long nozzle is connected with the lower nozzle of the ladle. During the continuous casting process, it effectively prevents the outside air from entering the molten steel, prevents the secondary oxidation of the molten steel, and improves the purity of the molten steel.
Tundish heat insulation ring: used for heat insulation and sealing of tundish upper nozzle and castable.
Zirconium-containing ceramic fiber cotton, with a fire resistance of up to 1430 ℃, is added with an appropriate amount of high-temperature inorganic binder, and is made into various products of different shapes through a special vacuum molding process. The products are hard, soft, and super-toughness; It is suitable for fire-resistant and heat-insulating sealing of special parts and special requirements. Advantages: good heat insulation, good sealing (nitrogen increase less than 2PPM), prevention of cold steel formation, easy disassembly.
