摘要： PURPOSE:To prevent the generation of bending in a pipe owing to uneven hardening in the stage of hardening the pipe by cooling water by enabling the centering and distance adjustment between a nozzle for injecting the cooling water and the pipe in water cooling of the pipe. CONSTITUTION:A long-sized pipe 11 to be subjected to water quench hardening is clamped by means of plural receiving bases 2-10, and the base 2 is placed on a traveling carriage 28 which is freely movable forward and backward. A nozzle 12 provided with an injection port 1 for cooling water for the purpose of cooling the pipe 11 is mounted horizontally movable on a lifting frame 19. The frame 19 is pinned 20 to a lifting device 22. The exact centering between the port 1 and the forward end of the pipe 11 is accomplished by the forward and backward movements of the carriage 28 and the forward, backward, upward and downward movements of the nozzle 12 in cooling and hardening the pipe 11 with the cooling water injected from the port 1; at the same time, the distance l1 therebetween is adequately adjusted by such movements, whereby the water quench hardening of the pipe 11 is uniformly accomplished and the bending of the pipe owing to uneven hardening is prevented.
