Advantages and disadvantages of high frequency induction heating machine
High-frequency induction heating machines have a wide range of applications, such as metal smelting, welding and other industries. It has the characteristics of fast heating speed and labor saving, which makes the whole operation process simpler. Kehua analyzed the advantages of high-frequency induction heating machines. disadvantage. Heating machine Advantages of induction heating 1. Induction heating does not need to heat the workpiece as a whole, but can selectively heat local parts, so as to achieve the purpose of less power consumption, and the deformation of the workpiece is not obvious. 2. The heating speed is fast, which can make the workpiece reach the required temperature in a very short time, even within 1 second. As a result, the surface oxidation and decarburization of the workpiece are relatively slight, and most workpieces do not need gas protection. 3. The surface hardened layer can be regulated by adjusting the operating frequency and power of the equipment as needed. As a result, the martensite structure of the hardened layer is finer, and the hardness, strength and toughness are relatively high. 4. The workpiece after heat treatment by induction heating has a thick toughness area under the surface hard layer, and has better compressive internal stress, which makes the workpiece's fatigue resistance and breaking ability higher. 5. The heating equipment is easy to install on the production line, easy to realize mechanization and automation, easy to manage, can effectively reduce transportation, save manpower and improve production efficiency. 6. One machine can be used for multiple purposes. It can complete the heat treatment processes such as quenching, annealing, tempering, normalizing, and quenching and tempering, and can also complete the work of welding, melting, hot assembly, hot disassembly and diathermy forming. 7. It is easy to use, simple to operate, and can be turned on or off at any time. And no preheating required. 8. It can be operated manually, or semi-automatically and fully automatically; it can work continuously for a long time, or it can be used randomly when it is used. It is conducive to the use of equipment during the power supply valley electricity price discount period. 9. High utilization rate of electric energy, environmental protection and energy saving, safety and reliability, and good working conditions for workers, which are advocated by the state. and many more. Disadvantages of induction heating Nothing is perfect, and it also has some disadvantages. For example, the equipment is relatively complex, the cost of one-time investment is relatively high, the interchangeability and adaptability of induction components (induction coils) are poor, and it is not suitable for application on some workpieces with complex shapes. Although there are some shortcomings, its comprehensive indicators are good, and the advantages are obviously more than the disadvantages. Therefore, induction heating is a main process of metal processing at present. It is an ideal choice for replacing coal heating, oil heating, gas heating, electric furnace heating, electric oven heating and other heating methods. Dear friends of the heating machine, the advantages and disadvantages of the high-frequency induction heating machine analyzed by Kehua will definitely help you when choosing.
