Abstract
An electroslag remelting and surfacing apparatus having a cooled mould comprising a plurality of superimposed sleeves which are electrically insulated from one another. The top sleeve of the mould, being substantially a non-consumable electrode, has a current lead and a lining of electrically conducting material. If provided with a radial electrically insulating layer, it may also serve as a single-coil inductor adapted to impart a rotary motion to the slag pool.
Claims4
In an electrode remelting and surfacing apparatus, a base plate connected to a power source and serving as a non-consumable electrode, a hollow water-cooled mould disposed to top said base for forming an ingot, said mould having an annular cross-sectional wall body forming an opened-end cavity and comprising at least three water cooled superimposed sleeves electrically insulated from one another with the middle sleeve or sleeves being of a height substantially smaller than that of the other sleeves, a top sleeve of said sleeves being electrically connected to said power source to serve as another non-consumable permanent electrode in the electroslag process and the top sleeve having a refractory and electrically conductive lining;
- said mould or said base plate being movable as said ingot is grown in said mould, whereby effective utilization of the entire slag pool area is achieved and said sleeve eliminating the need for a conventional consumable electrode.
