What is the intermediate frequency furnace, 5 aspects to understand the characteristics of the intermediate frequency furnace?

As a kind of induction furnace, the medium frequency furnace mainly provides steelmaking and other services for foundries, sand turning factories, etc. Because of its energy saving and environmental protection characteristics, it is deeply loved by users. The following are from saving, environmental protection, heating effect, efficiency and safety performance. Learn about the characteristics of the intermediate frequency furnace.

1. Saving features

Fast heating, high production efficiency, less oxidative decarburization, material and cost savings, and extended die life

Since the principle of medium frequency induction heating is electromagnetic induction, its heat is generated in the workpiece itself. The average worker can use the medium frequency electric furnace to carry out the continuous work of the forging task ten minutes after going to work. The professional workers do not need to burn the furnace and seal the furnace in advance. . Since the heating method has a high heating rate, the oxidation is extremely small, the oxidation burning loss of the intermediate frequency heating forging is only 0.5%, the oxidation burning loss of the gas furnace heating is 2%, the coal burning furnace reaches 3%, the intermediate frequency heating process material, each Compared with coal burning furnace, tons of forgings can save at least 20-50 kg of steel raw materials. Its material utilization rate can reach 95%. Because the heating method is evenly heated, the temperature difference of the core surface is extremely small, so the forging die life is greatly increased in forging, the surface roughness of the forging piece is also less than 50 um process energy saving, and the medium frequency heating specific gravity oil heating energy saving is 31.5% to 54.3%, Energy saving 5% to 40% than gas heating. The heating quality is good, which can reduce the scrap rate by 1.5%, increase the production rate by 10% to 30%, and extend the life of the mold by 10% to 15%.

2. Environmental characteristics

Excellent working environment, improve workers' working environment and company image, no pollution, low energy consumption

Compared with the coal stove, the induction heating furnace will not be bake and smoked by the coal stove under the scorching sun, but also meet the requirements of the environmental protection department, and at the same time establish the company's external image and the future development of the forging industry. trend. Induction heating is the most energy-efficient heating method in electric heating furnaces. The power consumption per ton of forgings heated from room temperature to 1100 °C is less than 360 degrees.

3. Heating effect

Uniform heating, minimal temperature difference between the core and high temperature control

Induction heating heat is generated in the workpiece itself, so the heating is uniform, and the temperature difference between the core and the core is extremely small. The application of a temperature control system enables precise control of temperature to improve product quality and yield.

4. Efficiency

The Yuhua intermediate frequency furnace has high heating efficiency, and the melting of a furnace iron only uses no more than 500 kWh, and the melting is more complete and faster.

5. Security performance

The medium frequency electric furnace remote control system is suitable for use in industrial environments. Strong anti-interference ability and high security. There is no wire connected between the operating device and the controlled device, that is, remote control. All complicated operations, press the button of the remote control at a long distance, after receiving the command from the intermediate frequency electric furnace, the corresponding operation can be completed step by step according to the best process. Because the electric furnace is a high-voltage electric appliance, it is not only safer, but also avoids panic. Operation error, causing damage to the electric furnace.

Intelligent remote control system, when there is steel splash, the furnace can quickly reduce the output power to a suitable value in one second, and then concentrate on the problem of impurities. When the furnace is calmed down, the power can be quickly increased to the maximum, saving not only The furnace time also played a role in power saving, and also reduced the loss caused by molten steel splash.
