Advantages of Induction Heating

Why choose induction heating instead of convection, radiation, open flame, or other heating methods?

The main benefits of induction heating for manufacturing are briefly described below:

Maximize Production Efficiency

Induction heating is fast, which can greatly improve production efficiency; heat can be generated directly and quickly inside the workpiece (for example, it can reach more than 1000 ℃ in 1 second). Starts up very quickly; no warm-up or cooling is required. The induction heating process can be done at the processing site near the cold or hot rolling mill without the need to send the workpieces in batches to remote furnace areas or subcontractors.

Energy Saving

This unique energy-saving process converts 90% of the energy into effective heat; the energy efficiency of conventional furnaces is only about 45%. And because induction heating does not require preheating and cooling cycles, standby heat loss is minimized.

Control and Automate Processes

Induction heating eliminates inconsistencies and quality problems associated with open flames, flaming, and other heating methods. After the system is properly calibrated and installed, errors can be eliminated, and the heating process is accurate and consistent.

Precise temperature control can be achieved with GH power, and the power can be turned on or off instantly. Through closed-circuit temperature control, the advanced induction heating system can measure the temperature of each different workpiece. It can set special heating, constant temperature, and cooling speed, and can record the data of each running workpiece.

Product Quality

With induction heating, the workpiece to be processed does not need to be in direct contact with a flame or other heating medium, but an induced current is generated inside the workpiece through an alternating current. As a result, product thermal deformation and reject rates are minimized. In order to improve product quality, the workpiece is enclosed in a vacuum environment, in an isolated container filled with an inert gas, or a reducing gas to eliminate the effect of oxidation.

Green Energy

Induction heating systems do not consume traditional fossil fuels; induction heating is a clean and non-polluting process that benefits the environment. The induction heating system does not generate smoke, heat waves, toxic gases, and noise, which can improve the working conditions of workers. Induction heating is safe and efficient and does not create open flames that could threaten worker safety or adversely affect the process. Has no effect on non-conductive materials and can be placed near heated areas without damage.

Using GH induction heating solutions can improve the working and maintenance conditions of equipment, avoid production failures, reduce energy consumption, and improve workpiece quality control.
