gluehkorb for degreasing and weichgluehen aluminium products

摘要

Annealing cage has at least one sidewall (16) connected to a frame (12) via at least one plastically deformed element (26) while heating to the annealing temperature (T) under a pressure produced in the cage by the heat expansion of the aluminum parts (20) onto the sidewalls so that the sidewall is pushed in a region bordering the frame about a quantity from outside thus increasing the cage volume.
