It will not be a secret how much electricity can be saved by electromagnetic heating of medium frequency induction furnace

How much electricity can be saved by electromagnetic heating is no secret. Our intermediate frequency induction furnace experiment will solve this mystery for you on the spot. Don’t be surprised! 

Energy saving is just saving, it cannot create new energy. At present, the resistance coil heating method is mainly used in the production of the plastic industry. This heating method mainly relies on single-sided contact conduction to transfer heat energy. At least 50% of the heat energy in this heat transfer method is dissipated in the air. Therefore, the so-called energy saving is to save the part of the energy dissipated in the air. In theory, half of the heat is transferred inside and outside the traditional heating circle. Therefore, according to the law of energy conservation, the electricity saving rate of electromagnetic heating should be 50% in theory. , The power saving rate in actual use should be about 40%.

However, because the medium frequency induction furnace plastic machinery relies on the rotation of the screw to push the material forward, the material is between the screw and the barrel, and has a large friction force, which is related to the speed of the screw, that is, the faster the speed, the greater the friction. The greater the friction, the more often this friction is converted into heat. In other words, as long as the screw speed is fast enough, it can generate enough heat. This relationship is usually considered in the design of the plastic machine, but due to the limitations of the current mechanical design and manufacturing capabilities, it is difficult for many equipment to achieve an ideal state, and they are uneven. Under this premise, some equipment just reaches an ideal heating state after modification, that is, the heat generated by the screw rotation is slightly greater than the heat required for production and processing. At this time, no external heat is needed at all. The lower power saving rate will be greater than 50% of the theoretical value, up to 80%. To sum up, we say that the normal energy-saving rate of electromagnetic heating energy-saving technology on plastic machinery is about 40%, and it can reach up to 80% under special circumstances. Therefore, the energy-saving rate of electromagnetic heating energy-saving renovation is precisely between 30% and 80%, and the specific value can only be known accurately after actual measurement. At present, some manufacturers refer to special as common for their own marketing needs, and it is a false statement to claim that the power saving rate generally reaches more than 60%.

At present, in the market, many companies report that after they use electromagnetic heating controllers for transformation, the control circuit boards will often burn out. Energy-saving new technologies have been questioned.

The reason for the above situation is that the concept of electromagnetic heating energy-saving technology has aroused the interest of many people in the industry, and is also very popular with enterprises. There are many manufacturers and service points who want to engage in or intend to intervene in this industry, and everyone rushes into battle. Too late or incapable of making the necessary electronic control technology preparations, the induction cooker control board is directly applied to the plastic machine required by the industrial grade for installation and use, and even some original manufacturers of induction cookers directly use the original induction cooker core for use.
