Hot-top for the production of ingots using an electroslag remelting process |
摘要 |
A hot-top for the production of ingots using an electroslag remelting process, comprises a ceramic hot-top having non-consumable electrodes embedded in the radially inner side walls thereof, the exposed surfaces of the electrodes comprising 5 to 50% of the total area of the hot-top inner surface. The electrodes extend parallel to the axis of the hot-top, from the top edge of the hot-top down at least 50% of the height thereof, and may be graphite or hollow water-cooled metal electrodes. In use, the electrodes contact not only the molten metal but also its superposed layer of slag.
