Medium frequency melting furnace is a kind of melting equipment using electromagnetic induction heating, which has the advantages of high efficiency, energy saving and environmental protection. Its melting temperature and melting speed have the following characteristics:
1. High melting temperature: the melting temperature of intermediate frequency melting furnace is usually high, generally can reach more than 1500 ℃. This is due to the role of intermediate frequency current in the conductor inside the conductor, the electromagnetic force produced by the intensive concentration of the surface layer of the conductor, resulting in an increase in the surface temperature, so as to achieve the effect of high-temperature melting.
2. Fast melting speed: the energy transfer efficiency of the medium frequency melting furnace is high, and the heating speed is fast. In a short period of time can make the metal material to reach a high temperature state, the heating range from the surface of the rapid conduction to the internal, uniform heating. Therefore, the melting speed of medium frequency melting furnace is faster, which can improve the melting efficiency and production capacity.
3. Low energy consumption: medium frequency melting furnace has high energy conversion efficiency, low energy loss and low energy consumption. The electromagnetic induction heating principle it adopts, so that electrical energy is directly converted into heat energy, compared with the traditional coal-fired and other ways, energy utilisation is higher, while reducing the pollution of the environment.

4. Good controllability: Medium frequency melting furnace has better temperature control performance. Through the adjustment of electromagnetic induction heating power, the temperature inside the furnace can be precisely controlled to meet the melting requirements of different materials. The equipment is also equipped with temperature monitoring, automatic control and protection devices, which can realise automatic operation and improve production efficiency and stability.
5. Wide range of application: Medium frequency melting furnace is suitable for melting various metal materials, such as iron, steel, copper, aluminium, zinc and so on. Moreover, due to its fast melting speed, the loss of melting material is small, suitable for high-quality, high requirements of the production field.
6. Easy to operate: medium frequency melting furnace adopts electronic operation and control system, easy to operate, can be intelligent control. Through the touch screen, PLC and other modern control technology, can achieve the furnace temperature, time, power and other digital adjustment, improve the stability of the production process and the degree of automation.
7. Safe and reliable: Medium frequency melting furnace adopts closed water-cooled induction coil, electromagnetic wave will not produce radiation to the operator and the surrounding environment, and there are protection devices to prevent arc and overheating phenomenon. Its structure is reasonable, easy to operate, with automatic power-off and alarm devices to ensure the safe and reliable operation of the equipment.
To sum up, the medium frequency melting furnace has the characteristics of high melting temperature, fast melting speed, low energy consumption, good temperature controllability, wide range of application, easy to control, safe and reliable. These features make the medium frequency melting furnace in the field of metal materials melting has a wide range of application prospects, become an important equipment in the metal melting industry.
