1、 Overview of Electromagnetic Induction Heating Energy saving Technology:

(Main content: New heating methods, heat conduction, heating body, thermal energy utilization rate, working environment temperature, insulation, and energy-saving rate)
In the industrial field, the application of electromagnetic induction heating is a new type of heating method. The heating method commonly used in traditional plastic machinery is resistance wire electric heating coils, which transfer heat to the material cylinder through contact conduction. The heat conductivity is less than 50%, and a large amount of heat is lost to the air. The result is not only a low utilization rate of electrical energy converted into thermal energy, but also a waste of electrical energy. Due to the large amount of thermal energy lost to the air, the working environment temperature rises. An electromagnetic heater is a device that uses the principle of electromagnetic induction to convert electrical energy into thermal energy. It consists of two parts: an electromagnetic controller and a heating coil. The electromagnetic controller rectifies 220V/380V, 50/60Hz AC power into DC power, and then converts the DC power into high-frequency high voltage power with a frequency of 20-40KHz. The rapidly changing high-frequency high voltage current flowing through the coil generates a rapidly changing alternating magnetic field, causing the metal material itself to generate heat at high speed, thereby heating the raw materials inside the metal material barrel; After applying electromagnetic induction heating, the metal drum can be insulated, greatly improving the efficiency of heat utilization and achieving the goal of energy saving; The power saving rate can generally be over 40%, with a maximum of 60%.

(Main content: engineering renovation content, product stability and reliability, three guarantees, after-sales service)
The implementation of the electromagnetic induction heating energy-saving technical renovation project only focuses on the renovation of the heating part of the original production equipment, that is, changing the heating method and replacing the original electric heating coil with electromagnetic induction heating equipment. The original temperature control system of the equipment is not changed, and the temperature is still controlled by the original temperature control system.

The heating coil is made of high-temperature resistant materials, without consumables or vulnerable parts. The product has high reliability and stability, and is easy to install and maintain.

3、 Benefit evaluation of electromagnetic induction heating technology renovation project for enterprises:

（Main content: direct benefits, indirect benefits, comprehensive benefits)
After the transformation of electromagnetic induction heating energy-saving technology, the average energy-saving rate of the heating part of the equipment is over 40%, which directly reduces the electricity expenses of the enterprise.
Compared to the original heating method of resistance plates, due to the use of high-temperature resistant coil materials and the application of insulation technology, there is no need to replace heating materials, reducing material costs.
The traditional heating method of resistor sheets inevitably leads to an increase in the working environment temperature, and even with the use of equipment such as fans for exhaust, the effect cannot be completely improved; Due to the extensive use of fan exhaust equipment, additional non productive electricity expenses are incurred; By adopting electromagnetic induction heating technology, this additional electricity cost can be reduced; Meanwhile, due to the improvement of the working environment, the special labor protection costs for workers can be reduced.
By adopting electromagnetic induction heating technology, based on the analysis and evaluation of direct and indirect benefits, the investment in energy-saving technology transformation for enterprises can be fully recovered within six months to one year for different types of plastic equipment; Due to the improvement of the working environment, it will directly affect the enthusiasm of workers, increase work efficiency, and enhance the image of the enterprise, with significant economic and social benefits.

4、 Analysis of the Effect of Electromagnetic Heater and Traditional Resistance Heating:

characteristic	electromagnetic heating	Resistance heating
thermal efficiency	The heat conversion efficiency of the high-efficiency energy-saving method is greater than 96%, which saves about 30% -80% of electricity compared to the resistance coil heating method under the same conditions	Made of resistance wire, the inner and outer sides of the coil generate heat, and the heat on the inner surface (closely attached to the material cylinder) is conducted to the material cylinder, while most of the heat on the outside is lost to the air, resulting in energy loss and waste. The thermal conversion efficiency can be used up to 50%
Warm-up time	Internal heating method: Heating parts of the body directly induce magnetic energy to generate heat, with an average preheating time reduced by half compared to the resistance coil heating method	External heating method: Only the inner resistance coil in contact with the heating element can conduct heat to the heating element, resulting in low heating efficiency and long heating time
Heating temperature	Almost no heat dissipation to the surrounding space, high power density, can be heated to temperatures above 400 ℃	Low power density, fast heat dissipation to peripheral space, generally difficult to heat up to above 350 ℃
work environment	Heat is concentrated inside the heating element, with almost no external heat dissipation. The surface of the equipment is touchable to the human body, and the ambient temperature has been reduced from above 100 ℃ when the resistance coil is heated to room temperature, greatly improving the working conditions on the production site. This will effectively increase workers' production enthusiasm and reduce the cost of ventilation and cooling in the factory area	Due to the significant loss of heat, the surrounding environment temperature rises, especially in summer, which has a great impact on the production environment. The working temperature on site exceeds 45 ℃, and some enterprises have to use exhaust ventilation or air conditioning equipment to reduce the temperature, which in turn causes secondary energy waste
service life And maintenance	The heating part uses intermediate frequency wires, which do not generate heat and can withstand high temperatures above 500 ℃, with a service life of over 5 years. No maintenance required, there are basically no maintenance costs in the later stage	Due to the use of resistance wire heating, the heating temperature can reach up to 300 ℃, and the resistance wire is prone to burning out due to high temperature aging. The service life of commonly used electric heating coils is about six months, so the maintenance workload is relatively large
capacity	High heating efficiency, coupled with uniform heating, can significantly reduce heating time and increase product yield

5、 Introduction to Electromagnetic Electric Heater:

1. Energy saving principle of electromagnetic heating:
At present, the heating method commonly used in plastic machinery on the market is electric heating coil heating, which transfers heat to the material cylinder through contact conduction. Only the heat on the inner side of the material cylinder is transferred to the material cylinder, and most of the heat on the outer side is dissipated into the air, resulting in thermal conduction loss and causing an increase in ambient temperature. In addition, the disadvantage of resistance wire heating is low power density, which cannot adapt to situations that require high temperatures. Electric heating technology is to make the metal cylinder generate heat by itself, and can be wrapped with a certain amount of insulation material on the outside of the cylinder according to the specific situation, which greatly reduces heat loss and improves thermal efficiency. Therefore, the energy-saving effect is very significant, up to 40%~60%.
