Magnetic conductor formula induction coil.
Background technology
In recent years, as the development of domestic and international oil and gas long distance pipeline steel pipe, big specification, high intensity straight-line joint submerged-arc welded (SAW) pipe obtain
Fast development, in the exploitation of Hi-grade steel pipeline steel tube, although China starts late, development speed is very fast.Vertical masonry joint submerged-arc welding
Pipe uses single steel plate as raw material, combines and is given birth to other welding procedures by JCO or UO shapings, submerged-arc welding or submerged-arc welding
Production, is characterized in that speed of production is very fast, and product quality is high, and stress distribution is uniform, and specification limit is big, and flexibility is high, especially
It is that can produce major diameter, the high-strength straight-seam welded pipe that ratio-frequency welded tube unit can not produce, but its production efficiency is less than ratio-frequency welding
Pipe, production cost are higher than ratio-frequency welded tube.When being heat-treated to heavy wall straight-line joint submerged arc welding tube, due to the spy of welded tube heavy wall itself
Point so that when being heated by general induction coil, it is difficult to completely heated up to weld dimensions progress, some places can go out
Existing temperature is relatively low, not up to heat treatment temperature requirement, and the efficiency of heating surface is low, and then influences structural transformation condition so that vertical masonry joint
Submerged-arc welded (SAW) pipe quality is reduced, hydraulic performance decline, and it can be caused potential safety hazard such as to occur being broken when deep-sea, deep-well are on active service when serious.
The content of the invention
For problem above, the utility model designs a kind of shared magnetic conductor formula for straight-line joint submerged arc welding tube sensing heating
Induction coil, can be by sharing the poly- magnetic of magnetic conductor formula induction coil, junction principle, and Welded Pipe weld seam is fully heated,
Heat treatment temperature requirement is ensure that, improves the efficiency of heating surface.
The utility model mainly includes water inlet, rectangle induction coil, cooling water pipe, U-shaped magnetic conductor, delivery port, level
Transfer station, rectangle induction coil are placed in above straight-line joint submerged arc welding tube weld seam, rectangle induction coil one end installation water inlet, the other end

On circle, opening direction is position to be heated, and straight-line joint submerged arc welding tube is positioned on horizontal transmission bench.Work substantially process：From rectangle
The water inlet water inlet of induction coil one end, from the delivery port water outlet of the rectangle induction coil other end, recirculated water is cooled down by dish type
The conveying of water pipe is cooled down to the rectangle induction coil of heating, cooled, and U-shaped magnetic conductor is embedded on rectangle induction coil, its
Opening direction is acted on so that square towards the weld dimensions below straight-line joint submerged arc welding tube by the aggregation of the magnetic line of force, junction
Temperature highest at shape induction coil center vertical direction, the efficiency of heating surface is most fast, then by horizontal transmission bench to straight-line joint submerged arc welding tube
Conveying, complete the heat treatment work to straight-line joint submerged arc welding tube.
The utility model device includes following technical scheme：As shown in figure 4, it is square that C, which is U-shaped magnetic conductor cross section, A and B,
Two cross sections of shape induction coil, 8 be the magnetic line of force caused by A section coils, and 9 be the magnetic line of force caused by B section coils, and 10 be A sections
The magnetic line of force and the common equivalent magnetic line of force distribution of the B sections magnetic line of force, it can be seen that, the induction coil design of magnetic conductor formula is shared, it is right
In poly- magnetic of two unicoils by a U-shaped magnetic conductor, junction effect so that the magnetic line of force distribution around rectangle induction coil
Density reaches up to maximum in center vertical side, herein temperature highest during sensing heating, to straight-line joint submerged arc welding tube weld seam and heat
The efficiency of heating surface of the zone of influence is most fast, meets the straight-line joint submerged arc welding tube heat treatment temperature requirement of heavy wall.
The advantages of the utility model comes than existing device band and good effect：
1st, the design of magnetic conductor formula induction coil is shared, two unicoils in rectangle induction coil U-shaped are led by one
The poly- magnetic of magnet, junction, which act on, causes the magnetic line of force distribution density around rectangle induction coil to be reached up to most in center vertical side
Greatly, herein sensing heating when temperature highest, it is most fast to the efficiency of heating surface of straight-line joint submerged arc welding tube weld dimensions, meet
The straight-line joint submerged arc welding tube heat treatment temperature requirement of heavy wall, improves the efficiency of heating surface.
2nd, the cooling water pipe design of disk-form, the rectangle induction coil to heating of high degree are cooled down, cooled, protected
The service life of rectangle induction coil is protected.
