Heat treatment installation, e.g. for salt, oil or water bath quenching and tempering of steel parts, has a quench bath walking beam system for positioning parts alternately on a base rack and a lifting beam during quenching

摘要

A heat treatment installation, comprising a quench bath walking beam system (50) for positioning a part (52) alternately on a base rack (48) and a lifting beam (51) during quenching, is new. A heat treatment installation includes a quench bath (44) containing a walking beam system (50) with a lifting beam (51) which cooperates with a base rack (48) and which reciprocates during quenching for alternate positioning of a part (52) on the base rack (48) and the lifting beam (51). An Independent claim is also included for a quenching process in which a part (52) is lowered into a quench bath (44), is positioned alternately on a lifting beam (51) and a base rack (48) and is then raised out of the bath.
