摘要

It provides a method for Tempering a Steel Tube and a device for Straightening a Steel Tube which can be achieved through a Steel Pipe with excellent quality by applying a uniform Uniform Rapid Cooling The Steel Tube in a longitudinal direction and in a sense cir Cunferencial Steel Tube through the use of a single Unit.Stop the movements of a Steel Tube heated in a Parallel and perpendicular to an Axis of the Steel Pipe, and discharge a stream of water cooling on the external surface of the steel tube from four or more spray nozzles arranged in Spiral out of the tub Or Steel and the Steel Tube is rotated around the Axis of the tube.Claim 5: a device to cool a Steel Tube, characterized in that it comprises: two or more rotating Rollers provided with a Steel Tube to rotate around an Axis of the heated Steel Tube; six or more spray nozzles arranged spirally at regular intervals F Out of the Steel Tube that is rotated by the rotating Rollers and Jet provided for DownloadS Cooling Water; two or more Heads provided to supply Cooling Water to the spray nozzles.
