Abstract

PURPOSE:To offer a quenching apparatus which can uniformly quench a workpiece, while reducing quench strain along a rotating direction, by locating a mechanism, which forcibly rotates the workpiece during quenching, at the opposite ends of the workpiece, and shifting a moving means provided with a movable heating coil and a cooler along the axis of the workpiece. CONSTITUTION:A moving means 3 provided with a heating induction coil 4, a cooling water sprayer 5 and an upper strain-releaving roller 6 for supporting a workpiece 9 from its upside is shifted along an arrow A, to successively quench the workpiece 9. During this period, one of means 11 and 12 for forcibly rotating the workpiece 9 along an arrow D dodges along an arrow B1 or C1 at a side near the means 3 when the means 3 comes in close to the means 11 or 12, in a manner such that quenching is done up to the ends of the workpiece 9, too, and that the workpiece 9 is constantly forcedly rotated by the other of the means 12 and 11. On the other hand, lower strain-releaving rollers 71, 81, which are not provided with forcible rotating mechanisms in themselves, accept the rotating force of the workpiece 9 along an arrow D, and continue rotation with a constant rotation number at all times, while releaving strain by their friction power with the workpiece 9. In this way, stable uniform quenching can be performed.
