Abstract
The casting apparatus includes an electro-slag mould (7) which includes a bath adapted to hold a pool of molten flux and an underlying pool of refined liquid metal and an exit passage extending downwardly from the bath. The casting apparatus further includes electrode carrier (FIG. 2) adapted to feed a consumable electrode (51) of raw metal into the bath and a power supply to pass a heating current from the electrode through the flux pool to melt the electrode. The apparatus further includes a product transporter (FIG. 1) to draw a cast product downwardly from the mould, and a drive (9,11) to effect concerted rotary oscillation about the axis of the product, of the mould, and of the product transporter.
