| titleOfInvention | A plastic ultra-high temperature ceramic sealing gasket for steelmaking submerged nozzle and its preparation method |
| abstract | The invention discloses a plastic ultra-high temperature ceramic sealing gasket for steelmaking submerged nozzles. The raw material formula of the ceramic sealing gasket is composed of outer layer raw materials and inner layer raw materials; wherein, the inner layer raw materials include the following parts by weight Components: 40-60 parts of alumina, 20-40 parts of magnesia-aluminum spinel, 10-30 parts of magnesium oxide, 5-30 parts of alumina sol, 5-10 parts of composite additives and 1-5 parts of moisturizing agent; The layer raw material is graphite material. It has good high-temperature service performance, good strength and plastic deformation performance, and is well filled between the lower nozzle of the tundish and the submerged nozzle to achieve complete filling and sealing, and completely isolate the air from entering through this part. to molten steel. |
