ABSTRACT:
An apparatus having an upper frame with a depending, telescopically elongatable and shortenable suspended structure for supporting at the lower end thereof a working platform in a converter or like metallurgical container, the upper frame being arranged to be supported at the upper end of the converter with the suspended structure extending down through an opening at the upper end of the converter. The apparatus has an endless conveyor which includes a vertical conveyor part extending from the upper frame to a point above the working platform, and a horizontal or inclined conveyor part situated outside the converter and the upper frame, the horizontal or inclined conveyor part permitting, upon elongation or shortening, shortening and elongation, respectively, of the vertical part of the endless conveyor. A device controls transfer of material from a conveyor device situated outside the converter, which can be the endless conveyor part outside the converter, so that the material is transferred in a controlled manner to an entrainment device associated with the vertical part of the conveyor.
