Homemade high frequency heating furnace

High frequency heating furnace
For the metallurgical industry, high-frequency heating furnace is an important equipment. The high-frequency heating furnace is a kind of equipment used for quenching various gears, sprockets and shafts.

 
Homemade high frequency heating furnace

In principle, it is based on the principle of high-frequency induction heating, and the concept is different. It is two types of industrial equipment of the general direction. It can be understood simply. The heating furnace is a furnace that uses a high-frequency induction principle to produce a heating furnace.


A heating furnace, in the metallurgical industry, refers to a device (industrial furnace) that heats a material or a general metal workpiece to a forging temperature. Applications include petroleum, chemical, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry, daily chemical, pharmaceutical and many other industries. High-frequency heating furnace, that is, a heating furnace made by the principle of high-frequency heating,

 When the magnetic flux surrounded by the conductor loop changes, an induced potential is generated in the loop. Similarly, the conductor in the alternating magnetic field is also induced by the electromagnetic induction to generate an induced current in the conductor (eddy current) ), the induced current overcomes the resistance of the conductor itself to generate Joule heat, and the heat is used to heat the conductor itself to warm it up and melt, thereby achieving various heat processing purposes, which is the principle of medium frequency induction heating.


The principle of the high-frequency induction heating machine is that it uses a high-current high-current current to flow into a circular induction state or a desired shape of the heating induction coil, and the high-cycle induction is usually made of a copper hollow tube. A strong magnetic flux that instantaneously changes in polarity is generated in the high-frequency induction coil, and the metal to be heat-treated is placed in the high-frequency coil, and the magnetic beam penetrates the entire heated metal object. In the opposite direction of the induction heating current inside the induction heating object, a corresponding strong eddy current is generated. Because the inductively heated metal has electrical resistance, it generates strong Joule heat energy, which causes the temperature of the object to be heated to rise rapidly, thereby achieving the purpose of heat treatment. Therefore, the high-frequency induction heating machine in the industry, can also be called: high-frequency induction heating equipment; high-intermediate frequency induction quenching equipment; induction diathermy equipment; high-frequency quenching machine, high-frequency induction heating machine, high-frequency welding machine.


◆ High-frequency induction heating machine adopts German Siemens IGBT module, soft-switching resonance double regulation and frequency automatic tracking system, Germany Infineon MOSFET device and unique frequency conversion technology, high-frequency operation is stable. The high-frequency induction heating machine has constant current and power control functions, which greatly optimizes the metal heating process.

◆ High-frequency induction heating machine has 50% power saving under the same conditions than traditional high-frequency tube heating equipment, no high-cycle radiation, no high-frequency interference. Reduced power load and power capacity, with 满负荷 full load design, high frequency induction heater can work 24 hours a day.

◆ High-frequency induction heating machine with automatic heating, heat preservation and cooling three-time function setting, which is beneficial to improve the heating quality of high-frequency induction heating machine and simplify manual operation. The high frequency induction heating machine power supply can be selected according to power and frequency. The higher the high frequency frequency, the shallower the heating depth, and the lower the high frequency frequency, the better the heat permeability. The high frequency frequency of the induction heating machine 1~20KHZ is automatically tracked.



Using MOSFET, IGBT power device and variable frequency control technology, it is efficient, energy-saving and has higher output power;
