Process and extrusion plant for producing a hub from a ceramic mass and Hubel

摘要

The invention relates to a method and an extrusion installation (2) for producing a hub (10) from a ceramic mass having a predetermined first diameter (D1). The extrusion plant (2) has at its end a mouthpiece (8) with an outlet diameter (D2) which is smaller than the first diameter (D1). The ceramic mass is pressed against a movable lifting table (14), wherein over the lifting table (14) a counterpressure on the mouthpiece (8) leaving ceramic mass is generated such that these for forming the Hub (10) to the first diameter ( D1) is extended.
