Method for cooling and calibrating extruded hollow profiles

摘要

Within the extruding profile, a conventional coolant atomization nozzle and an extraction nozzle are provided; in this case however, the atomizer includes a compressed air nozzle. Preferred features: The compressed air line (11) is concentric about the supply line for coolant (8) to the nozzle. Separat of the extraction opening (10a) from the nozzle (12) is 5-12 times, preferably 7-10 times the diameter (d) of the profile interior (2a). The suction device (10) is retractable.
