Submerged arc furnace with vertically movable frame

An adjusting device for an electrode in a metal smelter. The device has a pressure mechanism comprising a, preferably, one-piece, ring-shaped flexible tube filled with a pressure medium. The pressure mechanism is positioned between clamp elements and radially positioned around the electrode and a frame. To ensure the secure retention of the electrode and increase the service life of the material of the pressurization tube, through a simple structural means, the present invention provides that the clamp elements have retaining brackets and guide brackets that are positioned to slide horizontally on the frame and support elements that are partially in contact with the tube that is filled with the pressure medium. The support elements are provided on the clamp elements.

Apparatus for adjusting the position of an electrode in a metal smelting

An upper and a lower electrode section are mechanically interconnected through a nipple threaded into the lower electrode, as well as into a receiver on a tension rod pulling the nipple up, and thereby the lower electrode is urged against the front end of a twin wall upper electrode. The receiver is for its most parts surrounded by a twin wall sleeve passed through by cooling fluid and being suitably held within the upper electrode for axial displacement but bars intermittent contact with the receiver to obtain cooling thereof as well as of the connecting nipple.
