What are the advantages and disadvantages of electromagnetic induction heating?


1. 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.

2. The workpiece after heat treatment by induction heating has a thick toughness area under the surface hard layer, which has better compressive internal stress, which makes the workpiece's fatigue resistance and breaking ability higher.

3. 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.

4. It is easy to use, simple to operate, and can be started or stopped at any time. And no preheating required.

5. High utilization rate of electric energy, environmental protection and energy saving, safety and reliability, good working conditions for workers, advocated by the state, etc.



No product is perfect, and it also has some shortcomings. 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. It replaces coal heating, oil heating, gas heating, and electric furnace heating.
