Abstract

The method and the apparatus are applied, in particular for the secondary steel refinement. They improve the agitation of the metal. The apparatus includes an elongated vessel (10) the length of which has ratio to its width larger than 2. Vessel (10) has at least one heater (13) of canal type, and is adapted to operate when its long side is positiopned horizontally, 13 claims, 3 figures
