Description
Technical field
The present invention relates to the experimental provision of a kind of ERW steel-pipe welding temperature online Detection & Controling.
Background technology
High-frequency straight seam welded pipe (Electric Resistance Welding is called for short ERW) is a kind of form of electric resistance welding,
Be by hot rolled plate after forming machine molding, make coil of strip be deformed into round and smooth cylindric pipe, as the high frequency electric V by pipe
During shape angular aperture load circuit, the Kelvin effect strong due to it and kindred effect, force high frequency electric highly to concentrate on pipe
Base heating edge, and then weld zone is promptly heated reach welded condition by heat energy, under the effect of compression roller extruding force,
The fusing two edges of pipe fuse together, the cooled effect just reaching to weld together, and form steel pipe.In actual production
Cheng Zhong, ERW steel-pipe welding temperature is an important technological parameter in production process.Welding temperature is too high, easily makes weld seam
Burning, forms perforation；Welding temperature is too low, then weld seam cannot through welding, or there is sealing-off skip welding etc., affect weldquality, make
Become raw-material waste.In traditional ratio-frequency welded tube production process, welding temperature is with manual observation and regulation high frequency electric source
Output or speed of welding realize, and therefore welding tube quality is affected by many anthropic factors, and its stability is difficult to ensure that.Mesh
Before also have scholar's research pass through color comparison temperature measurement instrument directly to V-arrangement angular aperture summit measure welding temperature, but reality is in Welded Pipe Plant
Workshop, the fog produced due to coolant, the high temperature of welding region and roll and pipe are relative to the restriction etc. of position
Composite factor, measures welding temperature to V-arrangement angular aperture summit and can produce deviation with actual welding temperature.
Summary of the invention
It is an object of the invention to provide a kind of ERW steel-pipe welding temperature online detection that can accurately control welding temperature
With Control release device.
The experimental provision of the present invention, specifically includes that high frequency generator and output device, compression roller, roll shaft, frame, props up
Strut, connector, color comparison temperature measurement instrument and computer etc., wherein, high frequency generator and output device two ends thereof are by circuit and two
Individual electrode contact connects, and these two electrode contact symmetries centered by weld seam are pressed on pipe, and then high frequency electric passes through institute
State two electrode contacts and form loop with described pipe；Described pipe weld seam is positioned above center, and weld seam both sides are positioned at a pair
In compression roller, the vertical upper and lower two ends of roll shaft of this pair compression roller are separately mounted in frame, occur towards high frequency in frame
Device side is connected by securing member is vertical with support bar one end, and its axis is parallel with pipe axis, on this support bar discontinuously
Being socketed with some connectors, this connector a good appetite suddenly appearing in a serious disease portion is provided with outside through hole, and its top is additionally provided with the upper screw connected with middle through-hole,
Being provided with the holding screw engaged on this in screw, it can be solid by the connector position that can rotate on support bar and translate
Fixed.Described connector is arranged below engaging lug, and color comparison temperature measurement instrument is arranged on connection by the bolts and nuts being located on engaging lug
On part.Connector on described support bar, holding screw, color comparison temperature measurement instrument, bolts and nuts form a set of temperature measurement component, this survey
Temperature assembly is 3-6 set, preferably 3 sets, spacing 100mm, and the angle of color comparison temperature measurement instrument and vertical plane is 20 °.Every ratio
Color temperature measurer is all connected with computer by holding wire, and computer is further through holding wire and high frequency generator and output device phase thereof
Even, a closed-loop control system is formed；Then, the commissure temperature data measured all is passed through holding wire by every color comparison temperature measurement instrument
Being delivered to described computer, this computer self is by the theoretical value contrast of data with the numerical simulation of its internal memory, it was predicted that pad
Whether temperature meets the requirements, and adjusts described high frequency generator according to this temperature at weld value and output device exports the big of electric current
Little.
The present invention compared with prior art has the advantage that
1, color comparison temperature measurement instrument, computer and high frequency generator and output device one closed-loop control system of composition thereof, permissible
Accurately control welding temperature, it is ensured that welding tube quality.
2, color comparison temperature measurement instrument avoids the temperature directly measuring welding V-arrangement angular aperture summit, decreases what coolant produced
The impact that welding temperature is measured by fog.
3, also have certain distance due to point for measuring temperature to solder joint, the most just give the time that electric current adjusts, make the electricity mixed up
Stream just coincide with solder joint, it is to avoid prior art is i.e. surveyed and i.e. welded, the temperature deviation that causes after making the current hysteresis mixed up.
