[origin: US6022507A] PCT No. PCT/EP96/04693 Sec. 371 Date Sep. 11, 1998 Sec. 102(e) Date Sep. 11, 1998 PCT Filed Oct. 29, 1996 PCT Pub. No. WO97/17474 PCT Pub. Date May 15, 1997A blowing lance and a coupling head are configured to permit facilitated exchange of the blowing lance as desired. The coupling head includes a receptacle in which an end portion of the blowing lance is receivable. The receptacle includes a tubular attachment which engages a portion of the blowing lance, creating a hermetically sealed connection therebetween for conduction of a blowing fluid, for example, oxygen. The coupling head further includes connections for coolant supply and discharge. The blowing lance includes a cooling jacket having an inlet and outlet, at least one of which emerges at a peripheral surface thereof. When the blowing lance is received in the receptacle of the coupling head, at least one chamber is formed therebetween, providing sealed communication between the coolant supply and/or coolant discharge connections of the coupling head and the inlet and/or the outlet of the cooling jacket of the blowing lance, respectively.
