Verfahren für den Betrieb einer Multimediendüse und das Düsensystem

摘要

The invention relates to a method for operating multimedia tuyères in metallurgical processes, whereby the tuyère has at least two inlet channels for various gaseous, liquid, pneumatically conveyable, solid substances and any mixtures of these media, being applied in that one or more of these tuyères are disposed below and/or above the bath surface of a metallurgical smelt in the corresponding reaction vessel, wherein the media supply is temporarily switched off or the media pressure reduced to less than half the cut-in pressure in at least one of the media inlet channels of at least one multimedia tuyère during operation of a metallurgical process.
