Method and apparatus for producing a solid-section ingot by electroslag remelting

摘要

The method includes remelting consumable electrodes in a melting container and effecting a positive action upon crystallization of the ingot in the course of the melting operation, consisting in that a cooled body is brought into contact with the molten metal constituting the metal bath and the contact is maintained till the melting operation is complete by moving the cooled body at a speed close to the melting rate. On completion of the melting operation, the cooled body is extracted from the metal bath. The cooled body may be made in the form of a float or of an extension widened at the bottom and fixedly attached to a movable mold.
