Abstract
An electroslag remelting plant comprises a cooled mould, a base plate adapted for shaping the bottom part of an ingot, a single-phase transformer having a secondary winding with a midpoint, and two similar groups of electrodes, each one of the two groups of electrodes comprises at least two electrodes and being connected to one of the ends of the secondary winding of the single-phase transformer so that each two proximate adjacent electrodes have an opposite polarity.
Claims10
An electroslag remelting plant comprising:
- a cooled mould;
- a base plate adapted for shaping the bottom part of an ingot;
- a means having a hole arranged near the mould wall for bottom pouring of molten slag into the bottom part of the mould;
- a means having a hole for tapping molten slag from the mould accommodated in the top portion of the mould;
- a means mounted in the mould wall for detecting the level of molten metal in the mould;
- a single-phase transformer having a secondary winding with a midpoint electrically connected to the base plate and the mould;
- two similar groups of electrodes;
- each one of the two groups of the electrodes comprising at least two electrodes disposed in the mould and connected to one of the ends of the secondary winding of the single phase transformer so that each two proximate adjacent electrodes have an opposite polarity;
- a means for holding the electrodes immovable relative to each other over the mould and for supplying electric current to the electrodes;
- a means for moving the means for holding the electrodes in a vertical and a horizontal direction;
- a means for moving the mould in a vertical and a horizontal direction;
- and a means for moving the base plate in a horizontal direction.
