Abstract

Small parts are heat-treated in a protective atmosphere and then immersed in an oil bath (5) in which they are quenched. The protective gas enriched with oil vapour, from above the oil bath is extracted, the oil is subsequently separated from the extracted gas and returned to the oil bath and the protective gas, which is now free of oil vapour, is also returned to the heat-treatment chamber (1).
