Abstract

The energy consumption during electroslag remelting is determined to a considerable extent by the heat losses of a slag bath on the wall of a water-cooled ingot mould. A process and an ingot mould suitable for carrying it out wherein these heat losses may be avoided for the most part. Remelting thus takes place in a short, two-part sliding ingot mould known per se, except in the start-up phase, during normal block construction, the metal surface is always kept in the lower, water-cooled part of the ingot mould- that is below the line of separation between water-cooled part and insulated part of the same—by corresponding control of the relative movement between ingot mould and remelting block, so that the distance between the surface area of the metal surface on the one hand and the planes determined by the line of separation between cooled part and insulated part on the other hand, is at least 5 mm, but 100 mm at the most.
