Abstract: The invention relates to a method for the continuous extrusion of a metallic material, in which extrusion process the feedstock to be extruded is fed into the extrusion apparatus (4) by means of a feed member (2) advantageously provided with a groove on its outer circumference and a cooperating shoe (3) installed in said groove. According to the invention, the feed member (2) and the shoe (3) are adjusted at a desired distance from each other. In order to essentially maintain said desired distance and to eliminate the extrusion forces, the position of the shoe (3) in relation to the feed member (2) is maintained by means of an extrusion member (8) connected to the shoe (3).

Abstract: The invention relates to a method for producing a superconductor billet, in which superconductor billet there are used superconductor rods with a circular cross-section, and which superconductor billet can be extruded into a superconductor in a single-step extrusion process. According to the invention, the superconductor billet (12) is formed of interconnected blocks (1), into which blocks there are packed monofilament superconductor rods (5) with a circular cross-section.
