Cellular type U-shaped board, thread spindle, stay bolt, pad, nut, water inlet pipe, outlet pipe, positive plate and negative plate are by lag bolt with opening
Notch type supporting plate is connected, and nut is fixed otch formula supporting plate by coordinating with the screw thread of lag bolt, and thread spindle is placed in groove
In mouthful, thread spindle is fixed by the pretension of pad and nut, thread spindle lower end welding open-cell U-shaped board, open-cell U-shaped board groove
Stay bolt is installed, end turn is connected with stay bolt, and nut is coordinated by the screw thread of pad and stay bolt consolidates coil in hole
Fixed, water inlet pipe and outlet pipe are installed in coil both sides respectively, and end turn inlays magnetic conductor, and submerged arc pipe is placed in below two lateral coils,
Magnetic conductor opening direction alignment submerged arc pipe position to be heated.
The utility model device includes following technical scheme：As shown in Fig. 2 adjusted first according to the diameter of actual submerged arc pipe
Nodel line circle and submerged arc pipe ensure the distance of coil and submerged arc pipe in vertical direction for 3mm extremely in the relative position B of vertical direction
Between 15mm, then according to the width of actual submerged arc pipe weld seam, two lateral coils of regulation and the relative position of Weld pipe mill horizontal direction
Put A, ensure that the distance of coil and submerged arc pipe Weld pipe mill in the horizontal direction is 10mm between 90mm, finally according to actually burying
The radial direction of heating location needed for arc pipe and vertical direction institute are angled, by dismounting pad, then the method fastened with nut,
Angle C of two lateral coils in heating location radial direction needed for vertical direction and submerged arc pipe is adjusted, ensures coil in vertical direction
With submerged arc pipe needed for the angle of heating location radial direction be 90 °, finally realize two lateral coils to submerged arc pipe weld seam and heat affecting
Area is accurately symmetrically heated, and to reduce the thermograde of submerged arc pipe circumferentially and radially, reaches the purpose for eliminating residual stress；Heating
During, the water inlet pipe of coil both sides is cooled down to the induction coil of heating by connecting recirculated water with outlet pipe, cooled, with
Protect induction coil.
The advantages of the utility model comes than existing device band and good effect：
1st, vertical distance, the horizontal range and two of two lateral coils and Weld pipe mill of two lateral coils of regulation and submerged arc pipe are passed through
Radial angle of the lateral coil in heating location needed for vertical direction and submerged arc pipe so that the submerged-arc welding for different size can be done
To accurate, efficient symmetrical heating.
2nd, by dismounting pad, then the method fastened with nut, two lateral coils of regulation are needed for vertical direction and submerged arc pipe
The radial angle of heating location, simply and quickly realize change of two lateral coils to required heating location angle.
3rd, the apparatus structure is simple, easily operated, practical.
