Abstract
A cooling device (1) in the form of a vertically arranged hollow chamber is located between a heat treatment furnace (9) and a quenching bath (11d). The device controls the cooling of small hardware items dropping downwardly through it from the furnace (9) to the bath (11d). Spaced baffles (3) are arranged in the hollow chamber and are adjustably inclinable relative to the vertical. A heat transfer member is connected to the baffles so that heat can be removed from or stabilized in the small hardware items flowing over the baffles.
