Can electromagnetic heaters be applied to stainless steel heating?

2023-05-26    Views:285

It is possible. Electromagnetic heater is an efficient, energy-saving and environmentally friendly heating technology. It heats conductive materials through the principle of electromagnetic induction, including stainless steel, but only some stainless steel can. Stainless steel is also a diamagnetism material, but its magnetism is weak. Its heating efficiency is extremely low, so we say it does not heat. But some stainless steels have good magnetic conductivity, such as 430 and 409 steel. They are stainless steels with good magnetic conductivity, so their heating efficiency is high and heating is natural. Therefore, whether an electromagnetic heater can heat stainless steel depends on the material of the stainless steel.

As evidenced by measured data, using a special PWM&PFM hybrid modulation technology, a section of 316 stainless steel pipe with a diameter of 2 meters and a bowl mouth was powered on for a few seconds. The stainless steel pipe began to turn red, and a gust of hot air was clearly felt emanating from the pipe mouth. Capable of uniformly heating stainless steel 304 and 316, with a measured temperature of over 1000 degrees Celsius.


Therefore, electromagnetic heaters can be applied to stainless steel heating, such as in kitchen utensils, home appliances, chemicals, pharmaceuticals, food processing and other fields.


The use of an electromagnetic heater to heat stainless steel has the following characteristics:


Good controllability: The electromagnetic heater can achieve accurate temperature control and power control, meeting different heating requirements, thus achieving accurate heating.


Fast heating speed: The electromagnetic heater has the characteristic of fast heating, which can heat stainless steel to a stable temperature in a short time, thereby improving production efficiency.


Energy conservation and environmental protection: Electromagnetic heaters can accurately control heating time and temperature, reduce energy waste and emissions, and have the characteristics of energy conservation and environmental protection.


Uniform heating: The electromagnetic heater can evenly distribute heating on the surface of stainless steel, avoiding local overheating and burning on the surface of stainless steel.


It should be noted that the type and thickness of stainless steel materials are different. For different heating requirements, suitable electromagnetic heaters should be selected to ensure the heating effect and quality.
