Abstract
A container degassing device for an extrusion press is equipped with: a integrally formed degassing block joined to the end surface of the container of the extrusion press; a first sealing member that seals the degassing block; a second sealing member that seals the outer peripheral surface of an extrusion stem or a fixed dummy block of the extrusion press; and a vacuum suction device that sucks air from within a degassing space formed within the container. The degassing space is sealed by the degassing block and the first and second sealing members, and the area between the degassing block and the container end surface is sealed by a metal touch.
