Abstract
This invention provides a kind of heating roller used in the frequency treatment system of steel pipe, tube and drill pipe of oil well. The heating roller is fixed on the roller frame, which is inclining 0.3 to 1 degree on the horizontal direction. Several v-type roller and reducer with variable frequency adjustable speed motor on the roller frame. Induction heater is fixed between the v-type rollers. The angle between the roller and the steel pipe and the tube and drill pipe of oil well is 8 to 20 degree. This device ensure the steel pipe and the tube and drill pipe of oil well can be heated uniformly during the induction heating process. Using the v-type roller and the angle between the roller and the work piece is 8 to 15 degree and the speed of the roller is changing by frequency conversion timing. The work piece rotation in the induction loop and heated uniformly even it does not have the same axes with the loop. After the heating process the work piece dose not need to be straightened and it could save several million investment of the straightened machine.
Description
Technical field
What the present invention relates to is the heating roller-way that is used for steel pipe, oil well pipe and drilling rod intermediate frequency heat treatment system, belongs to thermal treatment attachment technique field.
Background technology
Prior art, be used for heating roller-way to workpiece steel pipe, oil well pipe and drilling rod thermal treatment, this heating roller-way is to guarantee steel pipe, oil well pipe and drilling rod rotation in heat-treatment process, steel pipe or oil well pipe or drilling rod heat inhomogeneous in heat-treatment process, steel pipe after the heating or oil well pipe or drilling rod have increased production cost widely through must be more straight through straightener behind this roller-way.
Summary of the invention
The objective of the invention is to defective at above-mentioned existence, the heating roller-way that proposes a kind of texture improvement is used for steel pipe, oil well pipe and drilling rod intermediate frequency heat treatment system, adopt the V-type running roller, workpiece steel pipe or oil well pipe or drilling rod are placed in the V-type running roller, tilt between the axis direction of V-type rolling axle and steel pipe or oil well pipe or drilling rod, roller speed adopts speed control by frequency variation.Steel pipe or oil well pipe or drilling rod even heating in heat treatment process can also be fine more straight behind steel pipe after the heating or oil well pipe or this roller-way of drilling rod process, the investment of having saved straightener.
Technical solution of the present invention: its structure is that the heating roller-way is installed on the roller bed frame, the downward-sloping in the horizontal direction 0.3-1 degree of heating roller-way; Install on the heating roller-way several V-type running rollers with the step-down gear of the band frequency control motor of the corresponding setting of V-type running roller, between V-type running roller and V-type running roller load coil is set, workpiece steel pipe or oil well pipe or drilling rod are placed in the V-type running roller, inclination 8-20 degree between the axis direction of the rolling axle of V-type running roller and workpiece steel pipe or oil well pipe or drilling rod.
Advantage of the present invention: guaranteed workpiece steel pipe or oil well pipe or drilling rod even heating in the induction heating treating processes, adopt the V-type running roller, workpiece steel pipe or oil well pipe or drilling rod are placed in the V-type running roller, tilt 8～15 ° between the axis of the rolling axle of V-type running roller and workpiece steel pipe or oil well pipe or drilling rod, roller speed adopts speed control by frequency variation.Workpiece steel pipe or oil well pipe or drilling rod rotation in ruhmkorff coil, even pipe and load coil disalignment, also can reach the effect of even heating, and workpiece steel pipe after the heating or oil well pipe or drilling rod have been saved the straightener investment of millions of units through can also be fine more straight behind this roller-way.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention.
In the accompanying drawing 1 is heating roller-way, the 2nd, roller bed frame, the 3rd, the step-down gear, the 4th of band frequency control motor, load coil, the 5th, V-type running roller.
Embodiment
Contrast accompanying drawing, its structure are that heating roller-way 1 is installed on the roller bed frame 2, the downward-sloping in the horizontal direction 0.3-1 degree of heating roller-way 1; Install on the heating roller-way 1 several V-type running rollers 5 with the step-down gear 3 of the band frequency control motor of V-type running roller 5 corresponding settings, workpiece steel pipe or oil well pipe or drilling rod are placed in the V-type running roller, between V-type running roller and V-type running roller load coil 4 is set, between the axis of the rolling axle of V-type running roller and workpiece steel pipe or oil well pipe or drilling rod inclination 8-20 °.
For guaranteeing workpiece steel pipe or oil well pipe or drilling rod homogeneous heating in the induction heating treating processes, we adopt workpiece steel pipe or oil well pipe or drilling rod rotation in ruhmkorff coil to reach this purpose.Adopt the V-type running roller, tilt 8～20 ° between the rolling axle of V-type running roller and workpiece steel pipe or oil well pipe or the drill rod axis.
The V-type roller speed adopts speed control by frequency variation.Even workpiece steel pipe or oil well pipe or drilling rod and induction state hot-wire coil disalignment, also can reach the effect of even heating, and workpiece steel pipe after the heating or oil well pipe or drilling rod have been saved the straightener investment of millions of units through can also be fine more straight behind this roller-way.
Claims (1)
1, the heating roller-way in steel pipe, oil well pipe and the drilling rod intermediate frequency heat treatment system is characterized in that heating roller-way and is installed on the roller bed frame, the downward-sloping in the horizontal direction 0.3-1 degree of heating roller-way; Install on the heating roller-way several V-type running rollers with the step-down gear of the band frequency control motor of the corresponding setting of V-type running roller, between V-type running roller and V-type running roller load coil is set, workpiece steel pipe or oil well pipe or drilling rod are placed in the V-type running roller, between the axis of the rolling axle of V-type running roller and steel pipe or oil well pipe or drilling rod inclination 8-20 °.
