Cabinet design

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

2. 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 forging task ten minutes after going to work. The professional workers do not need to burn the furnace and seal in advance. The furnace works, and there is no need to worry about the waste of the heated billet of the coal stove caused by power failure or equipment failure. Because the heating method has a fast heating rate, the oxidation is extremely small, and at least 20-50 kg of steel raw materials are saved per ton of forgings compared with the coal burning furnace, and the material utilization rate can reach 95%. Since the heating method is uniform in heating and the temperature difference of the core watch 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 50 um.

3. Induction heating The heat is generated in the workpiece itself, so the heating is even, the temperature difference between the core and the core is very small, and the temperature control system can realize the precise control of the temperature to improve the product quality and the pass rate.

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

5. The intermediate frequency furnace is the main equipment of the casting forging and heat treatment workshop. The stability, reliability and safety of the work are the guarantee for the normal and stable operation of the casting forging and heat treatment production lines of the flow operation. Excellent working environment, improve workers' working environment and company image, no pollution, low energy consumption. Induction heating is the most energy-efficient heating method in electric heating furnaces. The power consumption of tons of forgings heated from room temperature to 1100 °C is less than 360 degrees.

Main configuration and performance of medium frequency forging furnace

The medium frequency induction heating forging furnace is ultra-small, movable and covers an area of ​​only 0.6 square meters, which is convenient for use with any equipment;
It is very convenient to install, debug and operate.
It can reach the required temperature in a very short time, greatly reducing the oxidation of the metal;
The medium frequency heats the φ15 or more bar material, which is more diathery, more uniform, faster, and can work 24 hours a day;
Energy-saving and environmental protection, more uniform and rapid heat transfer, automatic feeding, greatly saving costs;
The furnace body is replaced to meet the different requirements of the overall heating or end heating of the bar.

◆ The length of the induction coil is usually 600mm or 800mm. When the material is coarse or long, the induction coil is even 1m long or more than 1m long, and 5-10 materials are heated. The induction coils are easy to replace, and different sizes of induction coils are used depending on the workpieces of different diameters.

◆ The output frequency is 1-10KHZ. According to the size of the heated workpiece, the induction coil and capacitor are designed to achieve different frequencies and adapt to the heating of different materials. When the material is fine, the heating frequency is higher, which can ensure the heat transfer and obtain higher heating efficiency; when the material is coarse, the frequency is lower, and the heat is ensured.

◆ Pneumatic feeding method, for a certain bar material, adjust the power of the equipment and the feeding rhythm, it can automatically launch the red bar for forging and pressing, which is very convenient to operate.

◆ Adopt IGBT device and adopt high efficiency combined resonance technology. Adopt low-inductance circuit arrangement and adopt large-scale digital circuit.
Main configuration and performance of medium frequency forging furnace
◆ Fast heating speed, high production efficiency, less oxidative decarburization, saving material and forging die cost. Since the principle of the intermediate frequency induction heating is electromagnetic induction, the heat is generated in the workpiece itself, and the ordinary worker can perform the continuous work of the forging task immediately after going to work with the intermediate frequency electric furnace. There is no need to worry about the waste of heated billets due to power outages or equipment failures. Because the heating method has a fast heating rate, the oxidation is extremely small, and each ton of forgings and the KGPS thyristor intermediate frequency furnace can save at least 20-50 kilograms of steel raw materials, which greatly saves electricity, and consumes 310 degrees of electricity per ton of steel. Compared with KGPS thyristor, the intermediate frequency saves 20%-30%. Because the heating method is evenly heated, the temperature difference of the core meter is extremely small, and the net side pollution, the power supply transformer does not generate heat, the substation compensation capacitor does not generate heat, and does not interfere with other equipment work. Reduce the power transformer capacity.

◆ Even heating, the core table temperature difference is very small, and the temperature control precision is high. 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 allows precise temperature control to improve product quality and yield.

◆ The whole equipment is small and compact, which is very convenient to use in the forging machine hot and forging machine.

◆ Excellent working environment, no pollution, low energy consumption.
