Advantages of medium frequency induction furnace
Medium frequency induction heating furnace is a power supply device that converts 50HZ AC power into medium frequency (from 300HZ to 1000HZ). Since the principle of medium frequency induction heating is electromagnetic induction, its heat is generated in the workpiece itself. Ordinary workers use an medium frequency electric furnace after going to work. The continuous work of the forging task can be carried out in ten minutes, without the need for professional furnace firing workers to perform furnace firing and sealing work in advance. Due to the fast heating speed of this heating method, there is very little oxidation. The oxidation burning loss of the medium frequency heating forging is only 0.5%, the oxidation burning loss of the gas furnace heating is 2%, and the coal burning furnace reaches 3%. The medium frequency heating process saves materials. Compared with coal-fired furnaces, a ton of forgings can save at least 20-50 kilograms of steel raw materials,which invisibly reduces production costs.
The medium frequency induction heating furnace has its own unique five advantages in heating and forging:
First, the melting and heating speed of the medium frequency induction heating furnace is fast, the furnace temperature is easy to control, and the production efficiency is high.
Second, the operation process of the medium frequency induction heating furnace is convenient, easy to learn, and easy to control.
Third, the temperature around the furnace of the medium frequency induction heating furnace is low, there is less smoke and dust, and the working environment is good, which is in line with the contemporary concept of energy saving and environmental protection.
Fourth, the medium frequency induction heating furnace has high melting efficiency, good energy-saving and power-saving effects, compact structure and strong overload capacity.
Fifth, the furnace utilization rate of the medium frequency induction heating furnace is relatively high, and it is very convenient to replace the furnace body.
The working principle of the medium frequency induction heating furnace is: the three-phase power frequency alternating current is rectified into direct current, and then the direct current is transformed into an adjustable medium frequency current, and the medium frequency alternating current flowing through the capacitor and the induction coil is supplied. High-density magnetic field lines are generated in the coil, and the metal material contained in the induction coil is cut, and a large eddy current is generated in the metal material. The medium frequency induction heating furnace is currently mainly used in: welding equipment, processing, thermoforming equipment and other fields. In the future The development potential is huge.
