Classification:
MFP intermediate frequency induction heating equipment
Key words:
MFP medium frequency induction heating equipment
Product Description
Medium frequency induction heating equipment is widely used in heating occasions that require heat penetration, such as: (1) heating and forging of standard parts; (2) melting of various metal materials; (3) heating and fitting of motor rotors; (4) heating and expanding the ends of steel pipes; (5) heat penetration for molds; (6) medium frequency quenching for shafts; (7) preheating or post-weld tempering of weld seams, etc.
Advantages of the equipment
1. Simple production operation, flexible material input and output, high degree of automation, can achieve online production.
2. Fast heating speed, high production efficiency, less oxidation and decarburization, saving material and forging die costs.
3. Uniform heating with minimal temperature difference between core and surface, high temperature control accuracy.
4. Complies with environmental protection requirements, low pollution, while also reducing workers' labor intensity.
Equipment characteristics
1. Fully solid-state IGBT frequency conversion and functional adjustment, soft switch resonance dual control and automatic frequency tracking technology ensure high reliability;
2. Ultra-small size saves customers 10 times the production space;
3. High efficiency and energy saving across the full power range with extremely high power factor and power supply efficiency;
4. Wide frequency automatic tracking adaptability from 1 to 20KHZ without on-site debugging;
5. Capable of continuous operation at full load for 24 hours;
6. Constant output voltage/constant output power control selection function;
7. Frequency, power, voltage, and current are all displayed.
Working principle
When the medium frequency current is transmitted from the medium frequency converter through capacitors via connecting busbars to the transformer, an alternating magnetic field is generated in the induction coil. The metal blank within this alternating magnetic field induces a current (eddy current), converting electrical energy into thermal energy to heat the surface of the blank.
Structural composition
The medium frequency quenching furnace body includes a compensation capacitor cabinet with internal compensation capacitors, cooling inlet/outlet paths, circuits etc.
A capacitor cabinet made from steel plates and profile steel is welded together with internal compensation capacitors installed; cooling inlet/outlet paths are provided; an output transformer is installed on top with a heating induction coil on its secondary side; both compensation capacitors and transformers use water cooling. RFM type water-cooled electric capacitor usage instructions are attached in Appendix A.
The cooling water circuit includes a water inlet distributor and a return water collector; both are welded from copper pipes with small nozzles welded on top for cooling water to reach the inlet distributor which cools the induction coil through it.Water-cooled guide rails, electric capacitors, capacitor busbars then concentrate back into the circulation pool through the return water collector.
The circuit part consists of two parts: one connects medium frequency power supply to capacitor busbars generally using power cables; for large powers >500KW, copper bars are recommended which need to be installed on-site according to actual conditions; second connects capacitor busbars to induction coils generally using water-cooled cables or square copper pipes which manufacturers usually connect beforehand so users typically do not need to operate unless replacing induction coils.
Connecting incoming lines
Connecting incoming lines refer to cables connecting transformers to medium frequency power supplies.
Cables connecting between medium frequency power supply and capacitor cabinet.The specifications for these cables refer to voltage levels (380V,660V) and currents passing through them.
Specific different cable or copper bar carrying capacities can be checked in electrical manuals or by consulting manufacturers.
Water cooling system
Medium frequency induction quenching equipment requires cooling water for high-power heating devices such as thyristors, smooth wave reactors, induction coils, electric capacitors etc. Currently there are two forms of water cooling systems available for users: one is closed-loop cooling water system detailed in closed-loop cooling system section; two is discharge-type cooling method using a pool with a pump.
