Title: Method and apparatus for feeding molten metal to an ingot during solidification
IPC: B22D23/10
Filed: 1978-02-03
Abstract: Molten metal is fed to an ingot during solidification, in order to compensate for shrinkage and segregation, by electroslag remelting (ESR).

Powdered solid slag can be filled in the space between the electrodes before ESR begins and for this purpose, the lower end of the outer or surrounding electrode is temporarily closed by a metal sheet which melts when the current is turned on, thereby to release molten slag onto the bath at the top of the ingot. The electrode arrangement is useful both with consumable and with nonconsumable electrodes.
