Patent Images
1. A system for electroslag smelting, comprising:
- a furnace having a wall, an internal atmosphere, and an external atmosphere;
a trough for accommodating an ore being smelted into a molten metal and a slag, the trough being disposed within the furnace, and the trough having an outer housing and an inner liner; and
a carbon electrode having a proximal end and a distal end, the electrode distal end being disposed in the trough, the electrode being submersible in the molten metal, and the electrode being separated from the slag by a ceramic barrier.

14. A method of electroslag smelting, comprising the steps of:
-
providing a furnace having a wall, an internal atmosphere, and an external atmosphere; providing a trough for accommodating the ore being smelted into a molten metal and a slag, the trough being disposed within the furnace, and the trough having an outer housing and an inner liner; providing a carbon electrode having a proximal end and a distal end, the electrode distal end being disposed in the trough, the electrode being submersible in the molten metal, and the electrode being separated from the slag by a ceramic barrier; and smelting the ore in the furnace, thereby providing a molten metal and a slag, the electrode being submersed in the molten metal, and the electrode being separated from the slag by the ceramic barrier. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
