Abstract (en)
[origin: DE10019306C1] Process for the controlled quenching of light metal cast pieces in a liquid bath comprises subjecting the cast pieces in the bath to gas bubbles, the bubbles being uniformly distributed at the base of the bath. AN Independent claim is also included for a device for the controlled quenching of light metal cast pieces in a liquid bath comprising a bath (11) filled with quenching liquid and connected to a gas bubble generator consisting of an air feed chamber (14) at the base of the bath with a cover (13) having a number of gas outlet openings. Preferred Features: The liquid in the bath is continuously circulated. The gas bubble stream is shut off before the cast pieces are removed from the bath.
