Coil induction quenching without open flame or conduction heating - Kehua
Coil high-frequency quenching is a new type of heating equipment. It does not require open flame or conduction heating. A large number of eddy currents will be generated inside to directly heat the object, which greatly improves its thermal efficiency. If you are interested, please follow Kehua Xiaobian to learn about it. ! Heat treatment high frequency quenching Heat treatment high frequency quenching is a new type of heating equipment. It uses the principle of electromagnetic induction and consists of a power converter, a control circuit, and an excitation coil (induction coil). The heated workpiece is placed in the induction coil. When working, an alternating current passes through the induction coil, and the frequency reaches several tens of kilohertz. An alternating magnetic field is generated around the induction coil, and most of the magnetic lines of the alternating magnetic field pass through the metal workpiece, generating A large number of eddy currents, the eddy currents make the iron molecules move randomly at high speed, and the molecules collide and rub against each other, thereby generating heat energy. It does not require an open flame or conduction heating, but allows the heat to be generated directly on the heated object, so the thermal efficiency is greatly improved. Coil high-frequency quenching Performance characteristics 1. Adopt IGBT power devices and unique inverter technology from internationally renowned companies, 100% load duration design, 24-hour operation under maximum power, high reliability guarantee. 2. It is light in weight, small in size and simple in installation. It can be connected to 380V three-phase power supply, water inlet and outlet, and it can be completed in a few minutes. 3. Especially safe, the output voltage is lower than 36V, avoiding the danger of high voltage electric shock. 4. The heating efficiency is as high as 90% or more, the energy consumption is only 20%-30% of the high frequency of the old-fashioned electronic tube, almost no electricity is needed in the standby state, and it can work continuously for 24 hours. 5. It occupies a very small area, is easy to operate, and can be learned in a few minutes. 6. The sensor can be freely and quickly disassembled and replaced, and the ultra-fast heating greatly reduces the oxidation deformation of the workpiece. 7. The equipment has the control function of constant current and constant power, which greatly optimizes the heating process of metal, realizes efficient and fast heating, and gives full play to the superior performance of the product. 8. The automatic control type can adjust heating time, heating power, holding time, holding power and cooling time; greatly improve the quality of heating products and the repeatability of heating, and simplify the operation technology of workers. 9. The latest environmentally friendly products that replace the heating of dangerous substances such as oxygen, acetylene, and coal, and production without open fire is safer and more secure. 10. The equipment has complete automatic protection functions such as overcurrent, overvoltage, overtemperature, water shortage, and lack of water, and is equipped with a fault self-diagnosis alarm system. Coil high-frequency quenching The above is the relevant introduction about coil high-frequency quenching. The equipment occupies a small area and the operation is very simple. Bar!
