Abstract
The utility model provides a water mist quenching device of a steel pipe and relates to an afterheat quenching device. The water mist quenching device comprises a pair of machine frame guide rails which are coaxially arranged opposite to each other; trolleys are respectively arranged on the two machine frame guide rails; the trolleys are provided with an upper water mist spraying pipe and a lower water mist spraying pipe; the spraying directions of the two water mist spraying pipes are opposite to each other; the water mist quenching device also comprises an aqueous vapor supply device which is connected with the water mist spraying pipes through pipelines; and a rotating supporting roller of the steel pipe is arranged between a pair of machine frames. The utility model can lead the inside and outside of the identical rotating line of the steel pipe to be uniformly cooled, and simultaneously, because the cooling is performed through rotation, the steel can not be out of round and further deformed. The technical proposal of the water mist spraying pipes is based on the structure of the long rotating arm, so the water mist spraying pipes can droop due to the reverse acting force and the gravity force of the sprayed mist in the operating process. Because the ends of the water mist spraying pipes arranged opposite to each other are provided with tapering coaxial positioning devices, the two water mist spraying pipes can be connected with each other after reaching the corresponding positions, and the trolleys exert certain axial force to enhance the rigidity of the water mist spraying pipes in the operating process.
Description
Technical field
The utility model relates to a kind of waste heat quenching device, relates in particular to the water fog quenching device in a kind of weldless steel tube processing.
Background technology
At present, weldless steel tube is used more and more and is taken precautions against, as oil well pipe, mechanical workout pipe etc., be used to produce oil well casing, mechanical workout has quenched and tempered steel and a non-hardened and tempered steel with pipe, adopt the weldless steel tube of quenched and tempered steel manufacturing to need to carry out quench treatment aborning, adopt the weldless steel tube of non-hardened and tempered steel manufacturing to need normalizing treatment.Comparatively speaking, the weldless steel tube cost that adopts quenched and tempered steel to make is low, has the stronger market competitiveness.Modulation is quenched shrend, oil quenching, and the production environment of oil quenching is abominable, and shrend is then different, environment is not had influence, and cost is low.Shrend divides mainly that trough inner water is quenched, the outer shrend of groove, trough inner water is quenched relatively and steel pipe, have following defective, the steel pipe of heating is after entering tank, and steel tube surface can produce boiling, form surperficial steam film, for steel pipe internal-surface, it is slower that the steam film at top is opened speed, makes speed of cooling inhomogeneous, be lower than the required critical cooling velocity of martensitic transformation as this partial speed of cooling, this part will lose the effect of quenching.The outer water quenching technology of groove has multiple Implementation Modes, and as outer tube layer stream, inner axial tube jet flow etc., but never a complete device can be implemented such technology.
The utility model content
The utility model provides a kind of steel pipe in process of cooling at above problem, axially, radially cooling evenly and can effectively overcome cracking, loses the steel pipe water fog quenching device of problems such as justifying.
The technical solution of the utility model is: comprise the coaxial pair of frame guide rail that is oppositely arranged, be respectively equipped with dolly on two rack rails, be provided with two water smoke jet pipes up and down on dolly, the spray direction of two water smoke jet pipes is oppositely arranged; It also comprises the aqueous vapor feedway, and the steam feedway links to each other by pipeline with the water smoke jet pipe; Between pair of frame, be provided with the rotating bearing roller of steel pipe.
On described each water smoke jet pipe plurality of nozzles is set evenly respectively, the adjacent nozzle interbody spacer has water smoke energy eclipsed distance before arriving steel tube surface of ejection.
The described termination of two water smoke jet pipes up and down that is positioned on the relative rack rail is respectively equipped with the positioned coaxially docking facilities.
Described water smoke jet pipe comprises outer tube, interior pipe, conduit, and interior pipe links to each other with nozzle, and outer tube links to each other with nozzle by conduit.
The steel pipe (more than 750 ℃) that the utility model will have waste heat is placed on the support roll by e Foerderanlage, and the dolly at feeding two ends moves the upper and lower water smoke jet pipe on the dolly then, respectively to the surfaces externally and internally correspondence of steel pipe; Start support roll, the rotation steel pipe starts the steam feedway, atomized water spray.Steel pipe limit rotation edge joint is subjected to the spray cooling of water smoke, because upper and lower water smoke jet pipe is corresponding, makes to act on the inside and outside even cooling of the same turning spur of steel pipe; Simultaneously, because cooling is accepted in rotation, make steel pipe can not lose the circle distortion.Consider the water smoke jet pipe of long arm structure form, when work, may be because opposition, the gravity of spraying make the generation of water smoke jet pipe sagging, the utility model is provided with the taper coaxial positioning apparatus in the termination of the water smoke jet pipe that is oppositely arranged, when promptly reaching the position, interconnect between two pipes, dolly applies certain axial force, the rigidity when working to increase the water smoke jet pipe.
