Device and process for automatic coupling of a casting ladle to one or more gas conduits

摘要

Automatic coupler for connecting a metallurgical ladle to one or more gas supply lines has a first coupler part (10) with several gas outlets (52) connected to a gas supply and a second coupler part (12) with several gas inlets (36), fixed to the ladle, each gas outlet (52) being closable by an associated stopper (56) in the first coupler part (10). The stoppers (56) of individual gas outlets (52) are arranged so that a single gas outlet is opened before the other outlets before one coupler part (12) is seated on the other coupler part (10). A method for automatically coupling a vessel to several gas supply lines is also claimed.
