Heat treating homogenized cooled cast light metal slugs or rod, comprises reheating, and subjecting to passive temperature compensation to lead to specified temperature uniformity

摘要

Heat treating homogenized cooled cast metallic slugs or a rod section made of a lightweight metal alloy comprises: (a) reheating the slugs /rod section for 20 minutes to a required temperature; and (b) subjecting the slugs/rod section to a passive temperature compensation for a maximum of 3 minutes, leading to a temperature uniformity of less than /! 10 K. An Independent claim is also included for a device for heat treating homogenized cooled cast metallic slugs or a rod section made of a lightweight metal alloy comprising a heating device connected to a cooling device.
