Abstract

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.
