Apparatus for rapidly and uniformly quenching coils of steel rod, tube or the like from an annealing temperature to a quench temperature by establishing a flow of quenching liquid from the inside of the coil about the wraps to the outside of the coil at a flow rate sufficient that the quenching liquid is maintained in its liquid state. The apparatus includes a quenching bath, means for lowering the coils into the bath, quenching liquid supply means disposed within the central open portion of the coils when lowered in the bath in quenching position, means to collet quenching liquid from around the outside diameter of the coils when in quenching position, and circulating means for providing a forced flow of quenching liquid from the supply means through the wraps of the coil to the collecting means. Preferred embodiments include a means for recirculating the quenching liquid, means for removing heat picked up from the coil wraps and means for controlling the temperature of the bath.
