Coreless induction furnace manufacturer will show you: the characteristics of induction furnace
Coreless induction furnace manufacturers tell you that an induction furnace is an electric furnace that uses the induction electric heating effect of the material to heat or melt the material. The AC power supply used in the induction furnace has three types: power frequency (50 or 60 Hz), intermediate frequency (150 ~ 10000 Hz) and high frequency (above 10000 Hz). The coreless induction furnace manufacturer tells you that the main components of the induction furnace are inductors, furnace bodies, power supplies, capacitors, and control systems. Under the action of the alternating electromagnetic field in the induction furnace, eddy currents are generated inside the material to achieve the effect of heating or melting. Coreless induction furnace manufacturers tell you that induction furnaces are usually divided into induction heating furnaces and smelting furnaces. Smelting furnaces are divided into core induction furnaces and coreless induction furnaces. The cored induction furnace is mainly used for the smelting and heat preservation of various cast iron and other metals. It can use waste furnace materials and has low smelting cost. Coreless induction furnace is divided into power frequency induction furnace, triple frequency induction furnace, generator set intermediate frequency induction furnace, thyristor intermediate frequency induction furnace, and high frequency induction furnace.
So what are the characteristics of induction furnaces?
1. Fast heating speed, high production efficiency, less oxidation decarburization, saving materials and forging die costs
The coreless induction furnace manufacturer tells you that because the principle of intermediate frequency induction heating is electromagnetic induction, the heat is generated in the workpiece itself. Ordinary workers can perform continuous forging tasks ten minutes after going to work with the intermediate frequency electric furnace, without the need for professional furnace burning workers to perform in advance Furnace burning and sealing work. There is no need to worry about the waste of heated billets in the coal furnace caused by power outages or equipment failures. The coreless induction furnace manufacturer tells you that due to the fast heating speed of this heating method, there is very little oxidation. Compared with the coal-fired furnace, each ton of forgings can save at least 20-50 kilograms of steel raw materials, and the material utilization rate can reach 95%. Because this heating method heats uniformly and the temperature difference between the core and the surface is extremely small, the life of the forging die is greatly increased in forging, and the surface roughness of the forging is also less than 50um.
2. The coreless induction furnace manufacturer tells you that the working environment is superior, it improves the labor environment of workers and the company's image, is pollution-free, low energy consumption, green and environmentally friendly, and meets the needs of modern industrial production.
Compared with the coal furnace, the induction heating furnace is no longer exposed to the baking and smoking of the coal furnace in the scorching sun, and it meets the requirements of various indicators of the environmental protection department. At the same time, it establishes the company's external image and the future development trend of the forging industry.
3. The heating is uniform, the temperature difference between the core and the surface is extremely small, and the temperature control accuracy is high
The coreless induction furnace manufacturer tells you that the heat of induction heating is generated in the workpiece itself, so the heating is uniform, and the temperature difference between the core and the surface is extremely small. The application of the temperature control system can realize the precise control of the temperature and improve the product quality and qualification rate.
In addition to these, what are the outstanding features: Coreless induction furnace manufacturers tell you that the heating device of the intermediate frequency furnace has the advantages of small size, light weight, high efficiency, excellent thermal processing quality and favorable environment, which are rapidly eliminating coal-fired furnaces, gas-fired furnaces, etc. Oil burners and ordinary resistance furnaces are a new generation of metal heating equipment.
