Abstract

To increase the extrusion speed for extrusion of light-weight metal such as aluminum, without incurring hot short cracks, or fissures, and retaining high-quality smooth surface of the extruded material, the region of the extrusion chamber immediately ahead of the extrusion die (3) is cooled by placing a cooling ring (12, 12') between the bore (9) of the extrusion cylinder in which the ram piston (13) operates. The cooling ring may be a unitary structure, or a multi-part structure, in which an independent inner ring is located within a cooling ring (12). For mechanical strength, a prestressing outer ring (20) is shrink-fitted around the cooling ring. The outer ring is retained, for example by screws (24), on the cylinder (2) within which the extrusion chamber (9, 10) is located. The cooling fluid may be water, a vaporizable liquid, or a gas, and is separated from the billet (1) within the extrusion chamber.
