Abstract
A device for coupling a blow lance with a header is disclosed, in which the force required for producing a sealing joint between the header (2) and the lance (4) is exerted by a cooling fluid and/or a blowing fluid. In a preferred embodiment, said cooling fluid and/or blowing fluid acts via a pressure surface (32) on the joint between the header (2) and the lance (4), the pressure surface being integral with a piston (22) which transmits the pressure to said joint. The lance has preferably a first coupling surface (12), while the header (2) has a second coupling surface (14), and one of said coupling surfaces (12 or 14) is integral with said piston (22).
