ABSTRACT:
A device for directing quench fluid onto the top of an inductively heated surface portion of a rotating workpiece has a supply means having an outlet end spaced horizontally from said surface portion for directing a jet of quench fluid therefrom and a deflector for intercepting and guiding the quench fluid jet onto the top of the heated surface portion of the workpiece. The spacing of the outlet end horizontally from the heated workpiece surface portion prevents the falling thereonto and contacting therewith of any drippage of residual quench fluid from the outlet end following shut-off of the supply of quench fluid thereto and during subsequent inductive reheating of the quench hardened surface portion to temper it.
