high frequencyinduction heatingThe inductor of the equipment is a very fine tooling component with high technical content, so the price is relatively high. Due to the effect of electromagnetic field, the inductor will generate electromotive force and vibration during the working process. When the coil and workpiece vibrate by electricity, harmful noise will be generated, and the service life of the coil will be reduced. In order to prevent the sensor from being deformed by external force, we not only use an insulating plate to support and reinforce the sensor, also be careful to use and maintain the sensor.

Before use, use gauze to clean the sensor and wipe its contact surface. During installation, in order to prevent the sensor from bumping and deforming, it should be handled gently, and the fixing bolts of the positioning block should be checked regularly to ensure that the pressing bolts are tightened or the eccentric chuck is clamped without looseness. When connecting the water circuit, the connection method should be correct and not omitted. When using multiple sensors at the same time in one place, put all sensors on the storage rack, and mark their numbers to avoid mistakes.

high frequencyinduction heatingThe gap between the sensor of the device and the heated workpiece should be checked regularly and adjusted according to the actual situation. If the sensor is deformed, the position of the magnet changes, or other parts are loose, it needs to be adjusted before use, and the sensor should be maintained in time after use. Before putting it back into the storage rack, use gauze to clean up iron filings and oil stains, otherwise repeated use will cause short circuit. When using the sensor, it needs to strengthen the sensor and high frequency.induction heatingThe degree of fit of the mechanical workpiece, that is, to reduce the gap between the inductor and the heating surface of the workpiece and improve the heating efficiency, the coil should be installed with a magnetic conductor, which can not only reduce the excess magnetic field, but also reduce the length between the conductive plates, increase the conductive area, and reduce unnecessary resistance loss and inductance loss on the inductor. A large number of experiments show that the more turns of the inductor, the higher the heating efficiency.

high frequencyinduction heatingThe equipment is a high-frequency induction generator used for metal heating. Electromagnetic induction is a non-contact heating of metal. If a metal object is inserted into the coil and alternating current is passed into the coil at the same time, a magnetic field will be generated, induction loss will be generated, and heat will be generated. According to the change of alternating current, electromagnetic induction in the magnetic field generates eddy current, and then eddy current generates joule heat and eddy current loss of electromagnetic energy.

The frequency of medium frequency induction heating equipment is 1KHZ-20KHZ, the typical value is 8KHZ, and the heating depth and thickness are about 3-10mm. It is mostly used for heating, annealing, tempering, tempering and surface quenching of large workpieces, large diameter shafts, large diameter thick wall tubes, large modulus gears and other workpieces, as well as punching red and forging of small diameter bars.

The frequency of high-frequency induction heating equipment is relatively high, ranging from 40 KHZ to 200 kHz, commonly used from 40 kHz to 80KHZ, and the heating depth and thickness are about 1-2mm. It is mostly used for deep heating, brazing, red punching, forging, annealing, tempering, quenching and tempering, surface quenching, medium-diameter pipe heating and welding, thermal assembly, pinion quenching, etc. The materials of small workpieces and heated workpieces are also different, usually low carbon steel, low alloy steel use medium frequency, austenitic stainless steel, copper alloy, aluminum alloy, titanium alloy use high frequency.
