Abstract: There is proposed a converter, comprising a body set up in a trunnion ring with trunnions on which multimotor drives are mounted with the gear hub of a low-speed reducer, with at least one trunnion being provided on the side of the multimotor drive with a bush and with said gear hub having a socket adapted to be joined with said bush, whose external surface is adjusted to fit in shape and size the corresponding surface of the socket, through which the trunnion is coupled with the gear hub of the low-speed reducer by means of a flexible joint.

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.
