Abstract

A process and device are disclosed for quenching workpieces (18). The workpieces (18) are exposed to a flow (26) of quenchant (12). The workpieces (18) and the quenchant (12) are reversibly moved in relation to each other. For that purpose, a first conveyor for the quenchant (12), in particular a pump (44), and a second conveyor, in particular a roller conveyor with transport rollers (16) for the workpieces (18), are designed with reversible transport directions.
