Description
Technical field
The present invention relates to high-frequency induction machine technical field, specially a kind of new energy high-frequency induction machine.
Background technology
Induction heating technique is at present to metal material efficiency of heating surface highest, fastest, and low consumption environmental protection.It is extensive
Applied to all trades and professions in the techniques such as the hot-working of metal material, heat treatment, hot assembly and welding, melting.It not only can be with
Workpiece is integrally heated, moreover it is possible to which the specific aim of workpiece part is heated；The deep layer that workpiece can be achieved is diathermanous, also can be only to its table
Heating is concentrated on face, surface layer；Metal material can not only be directly heated, can also carry out indirect type heating to nonmetallic materials.Etc..
Therefore, induction heating technique will be increasingly widely used.
The application of China's sensing heating industrially is started in the 50's of 20th century, in Machine Manufacture, weaving mechanism
Make, the application of the departments such as automobile, tractor industry it is earliest, induction heating technique at that time, the overwhelming majority comes from the former Soviet Union, small part
From countries such as Czech, Belgium.The 5's 0 Mos, China make vacuum-tube-type high-frequency power supply and mechanical medium frequency electric generating certainly
Machine, the various equipment and technologies such as induction melting, induction diathermic, quenching, medium heating are industrially applied in succession.60 years
Dai Hou, each department, enterprise develop thyristor intermediate frequency power supply, improve electron tube height in the case where self-reliance spirit is inspired
Frequency power, and the quenching machine of various types is designed, has manufactured, typical structure has collected into the 6th designing institute of former Machinery Ministry
Quenching machine atlas amounts to 55 kinds.Since opening, by going abroad on a tour of investigation, a variety of canals such as import equipment, imported technology
Road, the modern induction heating technique of industrially developed country have progressed into each department of China's industry, make sensing heating this
Energy saving, efficient, automation, high reproducibility, the technology of environmental protection are more effectively utilized.
Currently, induction heating power mainly uses thyristor, superaudio frequency range mainly to use IGBT in intermediate-frequency band, and
High-frequency band, since SIT is there are the usual chikung hot wind rate of the scarce thermoelectric generator such as high conduction loss is larger, to power device, passive device
There are many particular/special requirements for part, cable, wiring, ground connection and shielding etc..Therefore, induction heating power high frequency place heating electricity is realized
The development in source.
High capacity technology can be divided into two major classes by the high capacity of induction heating power from the viewpoint of circuit:
One kind is the series and parallel of device;Another kind of is the series and parallel of more bridges or more power supplys.It, must in the series and parallel mode of device
The voltage-sharing of Tandem devices and the equal flow problem of devices in parallel must be conscientiously handled, it is discrete due to device fabrication and parameter
Property, the series and parallel number of device is limited, and series and parallel number is more, the reliability of device is poorer.The series and parallel of more power supplys
Technology is the further capacity effective means again in device series and parallel technical foundation, by means of reliable power supply series and parallel
Technology, it is appropriate in single-machine capacity, Large Copacity device, every list can be obtained simply by the series and parallel method of operation
Machine is a unit of device.
Induction heating power inverter mainly has shunt chopper and series inverter, series inverter output that can be equivalent to
One low-impedance voltage source will cause very when two voltage source parallel connections when mutual amplitude, phase and frequency are different or fluctuate
Big circulation, so that the electric current of inversion device generates serious unevenness, therefore, there are parallel-operation expansion difficulties for series inverter；And it is right
See the shunt chopper of Buddhist ijwhnkigdfbn, the big reactor of direct current of inverter input terminal may act as between each shunt chopper
Current buffering link so that AG/DG the or DG/DG links of input terminal have sufficient time to correct DC current deviation,
Reach multi-machine parallel connection dilatation, transistorization superaudio, high-frequency current mostly use shunt chopper structure, and shunt chopper is easy to mould
Block, high capacity are one of main causes.

Fire, it can also be used to which differential annealing or tempering are also used for integral quenching and tempering sometimes.In the early 1930s, the U.S., elder generation of the Soviet Union
After start using induction heating method to part carry out surface hardening.With the development of industry, sensing heating heat treatment technics is not
Disconnected to improve, application range also constantly expands.
It puts the workpiece in inductor (coil), when being passed through the alternating current of certain frequency in inductor, surrounding is produced
Raw alternating magnetic field.The electromagnetic induction effect of alternating magnetic field makes to generate closed induced current in workpiece -- vortex.Induced current
Distribution on workpiece interface is very uneven, and workpiece surface current density is very high, is inwardly gradually reduced, and this phenomenon is known as collecting
Skin effect.The electric energy of workpiece surface high-density current is changed into thermal energy, and the temperature on surface layer is made to increase, that is, realizes surface heating.Electricity
Stream frequency is higher, and workpiece surface and internal current density difference are then bigger, and heating layer is thinner.It it is more than facing for steel in heating layer temperature
It is cooled down rapidly after boundary's point temperature, you can realize surface hardening.
According to the frequency of alternating current height, sensing heating can be heat-treated be divided into hyperfrequency, high frequency, superaudio, intermediate frequency,
5 class of power frequency.1. hyperfrequency sensing heating heat treatment power frequency used is up to 27 megahertzs, heating layer is very thin, only about 0.15 milli
Rice can be used for the thin layer surface quenching of the complex-shaped workpieces such as circular saw.2. high-frequency induction heating heat treatment electric current frequency used
Rate is usually 200~300 kilo hertzs, and heating layer depth is 0.5~2 millimeter, can be used for the parts such as gear, cylinder sleeve, cam, axis
Surface hardening.3. superaudio sensing heating heat treatment power frequency used is generally 20~30 kilo hertzs, with superaudio induced electricity
Stream heats fine module gear, and heating layer is substantially distributed along flank profil, and performance is preferable after pure fire.4. at Frequency Induction Heating heat
Reason power frequency used is generally 2.5~10 kilo hertzs, and heating layer depth is 2~8 millimeters, is chiefly used in large module gear, diameter
The surface hardening of the workpiece such as larger axis class and cold roll.5. line-frequency induction heating heat treatment power frequency used is 50~60
Conspicuous, heating layer depth is 10~15 millimeters, can be used for the surface hardening of large-scale workpiece.
