Abstract
This invention provides a kind of spray quenching equipment in the frequency treatment system of steel pipe, tube and drill pipe of oil well. The sprinkler is a circle distribution and the inlet pipe is connected with the pump. The spray quenching angle switch equipment is installed onto the sprinkler. Several muzzles are fixed to the sprinkler, which are distributed in taper or sector shape. All of the muzzles are symmetric set, the diameter of which is from 1.2mm to 4mm. The center line of the spray quenching equipment is coinciding with that of the steel pipe , tube and drill pipe. The advantages are: the continuum spray quenching process with product line can make the work pieces quenched properly. The average flatness of a 10-meters long work piece can come up to the US standard API, which is 0.2% of the total length from one end to the other. It couldn' t exceed 3.175 mm within 1524mm long. The spray pressure is controllable, the equipment can cool down quickly and the jam can be removed quickly. The angle of the muzzle is adjustable, which can reduce the backwater when the work pieces pass the spray quenching area.

Purpose of the present invention is intended to overcome the existing in prior technology defective, a kind of spraying and quenching device in steel pipe, oil well pipe and the drilling rod intermediate frequency heat treatment system that is more suitable for is proposed, this spraying and quenching device can guarantee evenly to cool off around workpiece steel pipe or oil well pipe or the drilling rod equably to workpiece steel pipe or oil well pipe and drilling rod jet surface quenchant.Long workpiece steel pipe or oil well pipe and drilling rod planeness reach U.S. API standard about 10 meters, measure from pipe one end the other end total length 0.2%.In every end 1524mm scope, must not exceed 3.175mm.
Technical solution of the present invention: its structure is to comprise spray thrower, water pump, the spray angle regulator of quenching, wherein spray thrower ringwise shape distribute; The water inlet pipe and the water pump of spray thrower join, and spray the angle regulator of quenching and are installed on the spray thrower, and several nozzles are housed on the spray thrower, and the diameter of this nozzle is 1.2-4mm, and the spray configuration of nozzle is cone-shaped or fan shape, and several nozzles are symmetrically arranged; The medullary ray workpiece steel pipe of spraying and quenching device or the medullary ray of oil well pipe or drilling rod are coaxial.
Advantage of the present invention: make the evenly through hardening fully rapidly of steel pipe, oil well pipe and drilling rod with the continuous spray of line.About 10 meters long workpiece measure from pipe one end the other end total length 0.2%.In each end 1524mm scope, must not exceed 3.175mm.Quenchant sprays around steel pipe, oil well pipe and drilling rod surface, guarantees the evenly cooling all around of steel pipe, oil well pipe and drilling rod.The pressure of jetting fluid is at 5～15Kg/cm
2Controlled, quenchant is destroyed rapidly at the steam film that steel pipe, oil well pipe and drilling rod surface generate, guarantee cooling fast, detachably nozzle guarantees in time to change nozzle and gets rid of the nozzle obstruction.Magnetic flow meter is installed at the water inlet pipe place, the pressure and temperature transmitter is regulated by PLC.The adjustable angle of the relative workpiece steel pipe of nozzle or oil well pipe or drill rod axis makes and enters that the backwater of quenchant to the rear portion reduces to minimum in workpiece steel pipe or oil well pipe or the drill pipe sub slit through the spray district of quenching.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention.
In the accompanying drawing 1 is spray thrower, the 2nd, and water pump, the 3rd sprays the angle regulator, the 4th of quenching, nozzle.
Embodiment
Contrast accompanying drawing, its structure are to comprise spray thrower 1, water pump 2, the spray angle regulator 3 of quenching, wherein spray thrower 1 ringwise shape distribute; The water inlet pipe of spray thrower 1 and water pump 2 join, spray the angle regulator 3 of quenching and be installed on the spray thrower 1, several nozzles 4 are housed on the spray thrower 1, the diameter of this nozzle 4 is 1.2-4mm, the spray configuration of nozzle 4 is cone-shaped or fan shape, and several nozzles 4 are symmetrically arranged; The medullary ray of spraying and quenching device is coaxial with the medullary ray of workpiece steel pipe or oil well pipe or drilling rod.
The pressure of water pump 2 is located at 5-15Kg/cm
2, nozzle 4 is dismountable.Magnetic flow meter, tensimeter and temperature sensor have been installed on the water inlet pipe of spray thrower 1.
Spray the angle that the angle regulator 3 of quenching can be regulated the relative workpiece spindle of nozzle axis.
During enforcement, coaxial for guaranteeing steel pipe, oil well pipe and drilling rod medullary ray with the medullary ray of ring spray device, and on medullary ray, pass through continuously.For adapting to different size, the spraying and quenching device center can up-down adjustment, left and right sides offset adjusted.Quenchant sprays around workpiece steel pipe or oil well pipe or drilling rod surface, guarantees the evenly cooling all around of workpiece steel pipe or oil well pipe or drilling rod.For quenchant is destroyed rapidly at the steam film of workpiece steel pipe or oil well pipe or the generation of drilling rod surface, guarantee cooling fast, the pressure of jetting fluid is located at 5～15Kg/cm
2About, and controlled.Be the processing parameter (as flow, pressure) that long-term stability keeps spray to quench, nozzle adopts the Wimet manufacturing.The endoporus of Wimet nozzle is from 1.2～4mm scope.Stop up for getting rid of nozzle, adopt detachable nozzle, guarantee in time to change nozzle.Bending deformation quantity for control workpiece steel pipe or oil well pipe or drilling rod, establish three sprays section of quenching in the spraying and quenching device, first spray section of quenching, but speed is suitably more slowly at the spray quenching in the 1st 2-3 second, prevent that chilling from producing distortion, angle is the 60-90 degree between nozzle 4 and workpiece steel pipe or oil well pipe or drill rod axis; Second spray section of quenching, its inside adds one supporting, spray in back the 3rd 3 seconds of 2-is quenched, flow and pressure strengthen, workpiece steel pipe or oil well pipe or drilling rod are cooled off fast, reach optimum regime for spray is quenched, the flow of quenchant, pressure and temperature is aligned automatically according to the processing parameter of setting, and angle is the 70-90 degree between nozzle 4 and workpiece steel pipe or oil well pipe or drill rod axis; The 3rd spray section of quenching, angle is the 80-90 degree between nozzle 4 and workpiece steel pipe or oil well pipe or drill rod axis.We quench in spray, and magnetic flow meter has been installed by medium ingress, the pressure and temperature transmitter can be regulated by PLC.Three sprays in the spraying and quenching device the quench relative workpiece steel pipe of nozzle of section or the adjustable angle joint of oil well pipe or drill rod axis can accomplish that like this workpiece steel pipe or oil well pipe or drilling rod make and enter that the backwater of quenchant to the rear portion reduces to minimum in workpiece steel pipe or oil well pipe or the drill pipe sub slit through the spray district of quenching.
