  • Tuyere for introducing reactants into a bath of molten metal
    Patent number: 3972517
    Abstract: The tuyere incorporates an elongated water-cooled tubular casing for admitting a flow of a gaseous reactant. Disposed co-axially in the casing is a pipe for admitting a flow of another reactant installed with provision for axial displacement. At the outlet from the casing there is provided a stopper with nozzles, said stopper being held fast on the pipe by means of its central portion. The internal surface of the casing mates the external side surface of the stopper with a region where said stopper is fitted, assuring the setting of the stopper into the working position with an interference bit. The withdrawal of the stopper from the working position is accomplished with the aid of said movable pipe.
