Method of sealing junction canals for liquid metal and canals sealed by using this method

摘要

Method of sealing, against the air, a space (1) existing between a vessel and a metallurgical canal, such as a space between, on the one hand, the intermediate outer nozzle (2) of a gate device (3) ensuring control of the casting of the liquid metal either from a steelworks casting ladle (4), or from a continuous-casting tundish (5), and, on the other hand, a canal, such as a long nozzle or immersed nozzle (6), the said method consisting in inserting a carbon seal into the abovementioned space, and metallurgical vessel and canal whose join is sealed against the air by virtue of the said method.
