Abstract
A device for extruding ingots, in particular for extruding light metal ingots through a shaping die placed downstream of the ingot, is provided with a scalping facility for removing an outer layer of the ingot immediately prior to extrusion. The said scalping facility is made up of a plurality of blades or similar scalping facilities which together form a scalping ring and can be moved radially with respect to the direction of extrusion, and can be released from the ingot.
