Evaluation of Flow Fields and Orientation Effects Around Ring Geometries During Quenching

The orientation in which parts are held during the quenching operation can have a strong effect on the overall success of heat treating. Certain orientations can result in significantly greater distortion than other orientations, even when high-quality quenchants are used. In this study, various simple, rolled ring geometries are examined at two different orientations to quenchant flow using computational fluid dynamics with the software program AZORE®. These parts were examined singly without the influence of other parts in close proximity. Three rolled ring geometries were examined, using the same outside diameter, while the inside diameter was varied. These flow fields will be used for understanding the likely distortion occurring during quenching.
