What is 15KW Medium Frequency Induction Melting Furnace Advantages?

KEXIN’s 15KW medium frequency induction melting furnace has fast heating speed, high production efficiency, less oxidation and decarburization, and saves material and forging die costs.

Since the principle of intermediate frequency induction heating is electromagnetic induction, the heat is generated in the workpiece itself. Ordinary workers can perform continuous forging tasks ten minutes after going to work with the intermediate frequency electric furnace, without the need for professional furnace workers to burn and seal the furnace in advance.

There is no need to worry about the waste of heated billets in the coal furnace caused by power outages or equipment failures. Due to the fast heating speed of this heating method, there is less oxidation. Compared with the coal burning furnace, each ton of forgings can save at least 20-50 kilograms of steel raw materials, and the material utilization rate can reach 95%. Because this heating method heats evenly and the temperature difference between the core and the surface is small, the life of the forging die is greatly increased in forging, and the surface roughness of the forging is also less than 50um.

The Working Principle of Medium Frequency Induction Melting Furnace

 

The 15KW medium frequency induction melting furnace generates an intermediate frequency power supply through the rectifier and inverter of the thyristor, and sends it to the furnace body coil. The intermediate frequency electromagnetic field is generated in the furnace body (coil), so that the metal in the furnace body produces eddy currents, and the eddy currents generate a large amount of metal. The heat energy melts the metal.

 

The 15KW medium frequency induction melting furnace is mainly composed of a power supply, an induction coil, and a crucible made of refractory materials in the induction coil. The crucible contains a metal furnace charge, which is equivalent to the secondary winding of the transformer. When the induction coil is connected to the AC power supply, an alternating magnetic field is generated in the induction coil. Since the charge itself forms a closed loop, the point of this secondary winding has only turns and is closed. Therefore, induction current is generated in the charge at the same time, and when the induced current passes through the charge, the charge is heated to promote its melting.

 

The 15KW medium frequency induction melting furnace is also a kind of induction furnace. The working process is as follows: first, through an inverter power supply, the three-phase alternating current is rectified (using a thyristor) into a single-phase direct current, and then the inverter bridge is inverted into a medium frequency of 500-1000Hz The pulsed alternating current then forms a magnetic field through the copper ring in the furnace. The magnetic field causes the steel in the ring to generate eddy currents, which flow through the heated steel to generate heat, thereby achieving the purpose of smelting the steel. The general frequency of intermediate frequency electric furnace is 800-20000Hz.

How exactly does induction hardening furance work?

In a basic induction heating setup, a solid state radio frequency power supply sends an AC current through an inductor (often a copper coil), and the part needs to be heated (the work piece) will be placed inside the inductor. The inductor serves as the transformer primary, and then the part needs to be heated therefore becomes a short circuit secondary. When a metal part is placed within the inductor and enters into the magnetic field, inside the part, the circulating eddy currents will be induced. These eddy currents generate precise and localized heat without any direct contact between the part and the inductor.

 

In the process of induction heating the material, there is therefore no contact between the inductor and the part, and neither are there any combustion gases. The material needs to be heated can be located in a setting isolated from the power supply, that is to say, it can be submerged in a liquid, covered by isolated substances, in gaseous atmospheres or even in a vacuum.

What is 15KW medium frequency induction furnace?

An induction furnace is an electric furnace in which heat is applied by heating metal by induction. The capacity of induction furnaces ranges from less than one kilogram to one hundred tons and is used to melt steel, copper, aluminum and precious metals.

Compared with most other metal melting methods, the advantages of induction furnaces are a clean, energy-efficient and controllable melting process.

Most modern foundries use this type of furnace. Now, more and more iron foundries use induction furnaces instead of cupolas to melt cast iron, because the former emits a lot of dust and other pollutants.

Since no arc or combustion is used, the temperature of the material is not higher than the temperature required for melting. This prevents the loss of valuable alloying elements.

One of the main disadvantages of using induction furnaces in foundries is the lack of refining capabilities. Oxidation products and known components in the charge must be removed, and some alloying elements may be lost due to oxidation (must be re-added to the melt).

 

What is the maximum temperature that the induction furnace can reach?

The 15KW medium frequency induction furnace does not limit its melting and/or heating temperature. However, refractory materials and materials containing heated or molten materials have limitations. For platinum melts, the highest temperature usually reached in the open air is about 1800°F. In a controlled atmosphere, heating graphite can reach temperatures exceeding 2760°C.

 

Does the induction furnace provide a complete vacuum heating and melting system?

The 15KW medium frequency induction furnace provides vacuum induction equipment, including induction power supplies, furnaces, coils, parallel components and power transmission components. However, the complete vacuum system including components such as vacuum chamber and vacuum pump will be provided by the vacuum system supplier or system integrator.
