Release Time : 2025-03-12
In today's industrial field, efficient energy saving has become an important consideration for equipment selection. As a new type of heating equipment, electromagnetic heating furnace has gradually become a new choice for industrial heating with its significant advantages such as efficient energy saving, intelligent control, safety and reliability.
1. Working principle of electromagnetic heating furnace
Electromagnetic heating furnace adopts the heating principle of magnetic field induction current, that is, eddy current heating. High-frequency current is generated by electronic circuit board, and 50HZ/60HZ alternating current is converted into DC voltage, and then the DC voltage is converted into high-frequency current with a frequency of 20-30KHZ through the control circuit. High-frequency current passes through the spiral magnetic induction coil to form a high-frequency alternating magnetic field. When the magnetic lines of force in the magnetic field pass through the heating part of the metal vessel (magnetic conductive material, also known as conductive material), alternating current, that is, eddy current, will be generated in the metal body. Eddy current makes metal atoms move irregularly at high speed, and atoms collide and rub against each other to generate heat energy, so that the appliance itself heats up at high speed, converts electrical energy into heat energy, and achieves efficient heating.
2. Application advantages of electromagnetic heating furnace
High efficiency and energy saving: The thermal efficiency of electromagnetic heating furnace is extremely high, usually reaching more than 93%, and the thermal efficiency of some high-end products can even be as high as 98%. Compared with the traditional resistance heating method, electromagnetic heating furnace can save a lot of electricity and reduce the operating costs of enterprises. At the same time, since there is no open flame and no combustion exhaust gas emission during electromagnetic heating, it is also in line with the current green environmental protection concept.
Intelligent control: The electromagnetic heating furnace is equipped with an advanced control system, which supports PLC programmable operation, RS485 communication human-machine interface interaction, etc., so that both power and water temperature can be accurately controlled. Users can set parameters such as heating temperature and heating time according to actual needs to achieve automatic control and improve production efficiency.
Safe and reliable: The design of electromagnetic heating furnace fully considers safety, and the heating core and the whole machine are separated from water and electricity to avoid the risk of electric shock. At the same time, the equipment is also equipped with multiple safety protection devices, such as overcurrent, overvoltage, undervoltage, coil short circuit and other protection functions to ensure that the equipment can operate stably even in harsh environments.
Small footprint: electromagnetic heating furnace is small in size, light in weight, small in footprint, and easy to install and move. This is undoubtedly a huge advantage for industrial plants with limited space.
Fast heating speed: Since electromagnetic heating uses eddy currents to directly heat metal utensils, the heating speed is extremely fast. This greatly improves production efficiency and shortens the heating cycle.
3. Application of electromagnetic heating furnace in the industrial field
Electromagnetic heating furnace is widely used in the industrial field, including but not limited to the following aspects:
Chemical production heating: In the chemical production process, various raw materials need to be heated. Electromagnetic heating furnace has become an ideal choice for chemical production heating with its high efficiency, energy saving and intelligent control.
Hot melt adhesive production heating: Hot melt adhesive needs to be heated and melted during its production process. Electromagnetic heating furnace can quickly and evenly heat hot melt adhesive, improving production efficiency and product quality.
Pharmaceutical pure water heating: Pure water heating is an important link in the pharmaceutical industry. Electromagnetic heating furnace can provide stable and precise heating temperature to ensure the quality and safety of pure water.
Oil pipeline heating: In the process of oil transportation, in order to prevent the crude oil in the pipeline from solidifying, the pipeline needs to be heated. Electromagnetic heating furnace can continuously heat along the pipeline to ensure the smooth transportation of crude oil.
In summary, electromagnetic heating furnace has gradually become a new choice for industrial heating with its significant advantages such as high efficiency and energy saving, intelligent control, safety and reliability. In the future industrial development, electromagnetic heating furnace will play a more important role and make greater contributions to energy saving and consumption reduction of enterprises and improving production efficiency.
