Abstract (en)

[origin: WO2018134018A1] Continuous extrusion process for a metal-containing bulk material (13) for producing an extruded body, comprising the following steps: introducing the metal-containing bulk material (13) into a press channel (8) of a metal-powder extrusion installation (1), which is bounded by a rotating extrusion wheel (2) and pressing tool components, which comprise a running-in region having sealing plates (5, 6, 7) and comprise a deflecting region with a counter plate (11) and a feeding plate (10), feeding in the metal-containing bulk material (13) via a peripheral groove (3) of the rotating extrusion wheel (2) to the counter plate (11) and deflecting the compacted metal-containing bulk material (13) in the deflecting region through the feed plate (10), which has an opening, to a die (12), wherein at least one of the sealing plates (5, 6, 7) arranged in the running-in region is cooled by means of a cooling device. The invention also relates to a metal-powder extrusion installation that is suitable for carrying out the extrusion process according to the invention.
