Abstract (en)
[origin: EP0962538A2] The workpiece (2) is cooled to a first critical temperature already in the furnace (1) by means of one or more directed gas streams. The workpiece is then transferred into the cooling chamber (6) without any contact with a damaging atmosphere. In the cooling chamber, the workpiece is subjected to quenching/cooling by means of a pressurized gas stream. An Independent claim is also included for an apparatus which includes a connector flange (3) which surrounds the opening (9) of the cooling chamber, and allows the latter to be docked to the heat treatment furnace. It further includes a workpiece transport unit (5) and a blocking unit (4).
