Electrotherm induction furnace price has always been a concern in the metal smelting industry, because induction furnaces have the highest heating efficiency and fastest speed for almost metal materials, and are low-consumption, energy-saving and environmentally friendly induction heating equipment. In recent years, it has been sought after by steel mills all over the world.
Features
The induction furnace is to convert the three-phase power frequency alternating current into direct current after rectification, and then convert the direct current into an adjustable current, supply the alternating current flowing through the capacitor and the induction coil, and generate high-density magnetic force lines in the induction coil, And cutting the metal material contained in the induction coil, a large eddy current is generated in the metal material. This eddy current also has some properties of current, that is, the free electrons of the metal itself flow in the metal body with resistance to generate heat, and this heat is the heat generated by the induction furnace itself.
The heating capacity of the induction furnace is the size of the heating power, which is directly related to the heated metal material, heating temperature, heating time, heating efficiency, material specifications and the heating weight of the metal material.
Therefore, the electrotherm induction furnace price will vary according to the requirements of material processing and so on.
Principle
Working principle of electric induction furnace
The high current of the high-frequency electric furnace flows to the heating coil (usually made of copper tube) wound into a ring or other shape. As a result, a strong magnetic flux with instantaneous polarity changes is generated in the coil. When a heated object such as a metal is placed in the coil, the magnetic flux will penetrate the entire heated object. In the opposite direction of the heating current inside the heated object, a The corresponding large eddy current. Due to the resistance in the object to be heated, a lot of Joule heat will be generated, and the temperature of the object itself will rise rapidly, achieving the purpose of heating all metal materials.
Classification
Induction electric furnaces can be divided into three types according to the power frequency:
high frequency furnaces, intermediate frequency furnaces and power frequency furnaces;
According to the purpose of the process, it can be divided into melting furnace, heating furnace, heat treatment equipment and welding equipment, etc.;
It can also be classified according to its structural form and transmission mode.
Commonly used induction furnaces are traditionally classified into heart induction melting furnaces, centerless induction melting furnaces, vacuum induction melting furnaces, induction hardening equipment and induction head heating equipment.
According to different functions, characteristics and electrotherm induction furnace price, among the induction melting furnaces that Hani Metallurgy has provided to customers over the years, high frequency induction furnaces and intermediate frequency induction furnaces have been demanded by more steel mills.
Induction melting furnaces are mainly used for melting and heat preservation of special steel, cast iron, non-ferrous metals and their alloys.
(1) High frequency melting furnace
The capacity of the high-frequency furnace is generally below 50 kg, and it is suitable for melting special steel and special alloys in laboratories and small-scale production.
(2) Intermediate frequency melting furnace
The capacity and power of the intermediate frequency melting furnace are larger than that of the high frequency furnace. It is mainly used for smelting special steel, magnetic alloy and copper alloy.
For a furnace with the same capacity, the input power of the intermediate frequency furnace is larger than that of the industrial frequency furnace, so the melting speed is faster. The intermediate frequency furnace does not need a furnace block when the cold furnace is melted, and the molten metal can be poured out, so it is more flexible and convenient to use than the industrial frequency furnace;
In addition, the intermediate frequency melting furnace solution has a lighter impact on the crucible, which is beneficial to the furnace lining. Therefore, after the development of high-power and cheap intermediate frequency power supplies, intermediate frequency furnaces are still promising.
No matter what kind of induction melting furnace, the corresponding electrotherm induction furnace price, Hani Metallurgy will give every customer according to the standards of suitability, professionalism, high efficiency and low energy consumption.
