#CMT# #/CMT# The method for the heat treatment of light metal-die casting part by solution annealing, cooling and ageing, is claimed, where the casting parts are solution annealed by infrared radiation in a mold for 1-5 minutes, then quenched for 2-5 minutes during spraying and aged. An aluminum- or magnesium die-cast alloy is used as alloy and the die cast part is solution annealed after the removal of the mold. The infrared radiation with wavelength of 2-3.5 mu m is used for cast- or die-casting part. The cast or die-cast part is quenched after heating at solution annealing temperature. #CMT# : #/CMT# The method for the heat treatment of light metal-die casting part by solution annealing, cooling and ageing, is claimed, where the casting parts are solution annealed by infrared radiation in a mold for 1-5 minutes, then quenched for 2-5 minutes during spraying and aged. An aluminum- or magnesium die-cast alloy is used as alloy and the die cast part is solution annealed after the removal of the mold. The infrared radiation with wavelength of 2-3.5 mu m is used for cast- or die-casting part. The cast or die-cast part is quenched after heating at solution annealing temperature in water, polymer or air. Punching is carried out in smooth condition of the die-cast parts after the quenching and before the ageing. An independent claim is included for a device for the heat treatment of light metal-pressure castings part. #CMT#USE : #/CMT# Method useful for the heat treatment of light metal-die casting part. #CMT#ADVANTAGE : #/CMT# The method ensures effective and economical heat treatment of light metal-die casting part with good stability. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a block diagram of a heat treatment of light metal-die casting part (Drawing includes non-English language text). |
