Abstract
A conveying arrangement for the dosed conveyance of bulk material from one metallurgical vessel into another through a conveying channel. The conveying channel has an entry opening and a discharge opening. A conveyor worm is rotatably located in the conveying channel, extending at least from the entry opening to the discharge opening and including a first flight formed by a plurality of paddles. In order to be able to configure the conveyor worm as short as possible and to minimize gas streaming through the conveying channel, the conveyor worm, on its end associated with the discharge opening, has a second flight that is formed by a continuous helix extending at least over half a convolution.
