  • Patent number: 4615036
    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.

  • Patent number: 4207060
    Abstract: A vessel for a metal smelting furnace is disclosed. The vessel is provided with a heat-resistant interior wall and means for cooling the portions of said interior wall above the smelting zone. In accordance with the invention, the cooling means comprises an interior wall at least partially formed by at least one cooling pipe coil wherein the coil includes thick-walled pipes and neighboring sections of the coil are arranged in a closely adjacent relation. A cooling medium such as water is fed through the pipe coil under high pressure to dissipate heat from the interior wall of the vessel.
