Medium Frequency Diathermy Furnace

Features of Induction Furnace

1. IGBT power device and unique inverter technology are adopted, 100% load duration design, 24-hour operation under maximum power, and high reliability are guaranteed.

2. It has the advantages of being lightweight, small volume and simple installation. It can be completed in a few minutes by connecting 380V three-phase power supply, water inlet, and water outlet.

3. The heating efficiency is more than 90%, and the energy consumption is only 20% – 30% of that of the old electronic tube. There is almost no electricity in standby mode, and it can work continuously for 24 hours.

4. The 500kW induction furnace has the heating indication in the heating process, with convenient output power adjustment, fast reaction speed, accurate control, and arbitrary selection of heating conditions.

5. Especially safe, the output voltage is lower than 36V, avoiding the risk of high-voltage electric shock.

6. It has perfect automatic protection functions such as overcurrent, overvoltage, overtemperature, water shortage and shortage, and is equipped with the fault self-diagnosis alarm system.

7. It can replace other heating methods (such as gas, coking coal, oil furnace, electric furnace, electronic tube, high frequency, etc.) for energy conservation and environmental protection. Moreover, the floor space is very small and the operation is simple, which can be learned in a few minutes.

8. It can complete heat treatment processes such as quenching, annealing, tempering, normalizing and quenching and tempering, as well as welding, melting, thermal assembly, thermal disassembly and diathermal forming.

Advantages

1. Fast heating speed, high production efficiency, less oxidation decarbonization, saving material and forging die cost

As the working principle of the medium frequency diathermy furnace is electromagnetic induction, its heat is generated in the workpiece itself. Ordinary workers can carry out continuous forging tasks ten minutes after working with the medium-frequency electric furnace, and there is no need for professional workers to burn and seal the furnace in advance. There is no need to worry about the waste of heated blanks in the coal furnace caused by power failure or equipment failure. Due to the fast heating speed of this heating method, there is little oxidation. Compared with coal-fired furnaces, each ton of forging saves at least 20-50kg of steel raw materials, and its material utilization rate can reach 95%. Because the heating method is uniform and the temperature difference between the core and surface is very small, it also greatly increases the service life of the forging die in terms of forging, and the roughness of the forging surface is less than 50um.

2. Superior working environment, improving workers’ working environment and company image, no pollution and low energy consumption

Compared with the coal stove, the workers of the medium frequency diathermy stove will no longer be baked and smoked by the coal stove in the scorching sun, and can better meet the index requirements of the environmental protection department. At the same time, it can establish the external image of the company and the future development trend of the forging industry.

3. The heating is uniform, the temperature difference between the core and the meter is very small, and the temperature control accuracy is high

Induction heating generates its own heat in the workpiece, so the heating is uniform and the temperature difference between core and surface is very small. The application of a temperature control system can realize the accurate control of temperature and improve product quality and qualification rate.

The heating device of medium frequency diathermy furnace has the advantages of small volume, lightweight, high efficiency, excellent thermal processing quality and a favorable environment. It is rapidly eliminating coal-fired furnaces, gas furnaces, oil-fired furnaces and ordinary resistance furnaces. It is a new generation of metal heating equipment.

4. Fast melting speed, power saving, energy saving, less burning loss and easy to start

The stability, reliability, and safety of the main equipment in the medium frequency diathermy forging and heat treatment workshop are the guarantees for the normal and stable operation of the forging and heat treatment production line of flow operation.
