Abstract
A tiltable metallurgical vessel is rotatable about pivot pins which are supported in bearings. At least one of the pivot pins is hollow so that a material carrying conduit can pass through the pivot pin desired materials from a remote source to a desired operational site of the furnace. In addition, other material carrying conduits are provided to the operational sites of the furnace. These latter conduits are connected, at one end, to stationary tapping points and, at the other end, to the operational sites of the vessel. The conduits are guided around (by being coiled by at least one full turn) an enlarged cylindrical portion of the hollow pivot pins. In one embodiment of the invention, the enlarged cylindrical portion of the hollow pins are winding drums which are themselves constructed of symmetrical cylinder halves. In this manner, the winding drum can be easily retrofitted onto a preexisting vessel. In another aspect of the invention, a tensioning device is provided for the elimination of slack of the flexible conduits. The tensioning device, in the preferred embodiment, is in the form of a weighted guide roller.
