Abstract
A metallurgical melting vessel has a vertical shaft, surrounded by a housing wall, which receives steel scrap. At least one closure element, having laterally spaced-apart fingers extending parallel to one another, is mounted such that it can move between a closed position and an open position. In the closed position, the fingers protrude at least partially into the shaft for the purpose of holding back steel scrap. In the open position, the fingers free the shaft at least to such an extent that the steel scrap can fall from the shaft into the melting vessel. The at least one closure element is mounted so as to be movable from the side of the shaft into the shaft and laterally thereoutof.
