Abstract

An apparatus (10) for heat treat hardening multiple wear surfaces (24,26,28) of a metal workpart (14). Flame burners (38) and associated trailing quenches (36) travel along a linear and vertical path (13) across the workpart (14) to flame harden the wear surfaces (24,26,28) thereon. The workpart (14) is mounted on support studs (60) extending from a turntable (52), and clamping arms (66) securely engage the workpart (14) with the support studs (60). The turntable (52) rotates the workpart (14) relative to the travel path (13) of the flame burners (38) to move flame hardened surfaces (24,26,28) out of the travel path (13) and move unhardened surfaces (24,26,28) into the travel path (13) for flame hardening by the flame burners (38).
