Abstract In order to improve the high temperature resistance and poor tightness of the traditional gasket, a new high temperature resistant plastic ceramic gasket was developed independently. With a new thermoplastic ceramic gasket, the aluminum loss of 1450CCM steel decreased by 15%, the Titanium loss decreased by 20%, and the abnormal proportion of “aluminum loss not less than 0.004%, nitrogen increase not less than 0.000 85%” of oriented silicon steel was reduced. The cleaning is not necessary when nozzles in tundish were continuously used for less than three times. The amount of argon sealing at the long nozzle was reduced from 580 to 380 NL/min. The liquid level of tundish casting flow area is calm and the casting ability is good.
