Abstract

Die Erfindung befaßt sich mit einem Flachrezipienten für Strangpressen, welcher aus mehreren Teilen (3,4,5) gebildet ist und einen durch Ausrundungen begrenzten Durchbruch (2) aufweist sowie einem Verfahren zur Herstellung desselben. Erfindungsgemäß ist vorgesehen, daß die Innenbüchse (3) oder die Ausrundungsteile über deren Längserstreckung mechanisch oder thermisch behandelt werden, während welcher Behandlung zumindest teilweise eine plastische Verformung des Werkstoffes unterhalb der Anlaßtemperatur durchgeführt wird und zumindest im Bereich der Ausrundungen in der oberflächennahnen Zone (31,31′) der Innenbüchse (3) erhöhte Druckspannungen gebildet sind. The invention relates to a flat recipient for extrusion presses, which is formed from several parts (3, 4, 5) and has an opening (2) delimited by fillets, and to a method for producing the same. According to the invention, the inner sleeve (3) or the rounded parts are treated mechanically or thermally along their longitudinal extent, during which treatment a plastic deformation of the material is carried out at least partially below the tempering temperature and at least in the area of the rounded areas in the near-surface zone (31, 31 ') of the inner sleeve (3) increased compressive stresses are formed.
