Abstract
The system described herein relates to working a metal casting strand that is round in cross-section, by reducing the cross-section in the final solidification region with the aid of at least three forming tools which are distributed around the circumference and act simultaneously on the casting strand. In order to provide advantageous working conditions, the casting strand is formed by forging tools constituting the forming tools in a longitudinal portion for each forming stroke, which portion corresponds to at least a fourth of the strand diameter before the reduction in cross-section. The forging tools are rotated by an angle step about the axis of the casting strand 1 between the forming strokes.
