Luoyang HongtengIntermediate frequency induction furnace
As a manufacturer of industrial furnaces, we produce many medium frequency induction furnaces. Medium frequency induction heating has the characteristics of fast heating, uniform heating, non-contact heating, no pollution, small operation area and high productivity, so it is used in many fields such as surface quenching of industrial metal parts, metal melting, bar heat penetration, etc. It is becoming more and more widespread, so do you know what the principle of medium frequency induction heating is? The principle of intermediate frequency induction heating is to use the method of electromagnetic induction. When the magnetic flux surrounded by the conductor loop changes, an induced potential will be generated in the loop. The conductor in the alternating magnetic field also generates an induced potential under the action of electromagnetic induction, and an induced current is formed in the conductor. The induced current overcomes the resistance of the conductor itself to generate Joule heat, and this heat is used to heat the conductor itself, causing it to heat up and melt. To achieve a variety of thermal processing purposes. The basic components of an induction heating system include an induction coil, an AC power source and a workpiece. Depending on the heating object,...
After the user purchases an induction cooker, there may be some problems. As the main smelting equipment in the foundry industry, the design and manufacture of the induction furnace are the key steps, but after the induction furnace is delivered to the user’s work site, the installation and commissioning are the top priorities for the stable operation of the induction furnace. Luoyang Hongteng Xiaobian talks about the installation experience of induction furnace. Preparation before installation of induction furnace First, check whether the main components of the induction furnace and its installation materials are complete according to the installation list of the induction furnace, and check their condition. The defects of some parts and materials caused by improper transportation and storage should be repaired, so that all equipment, parts, corresponding materials and parts are intact, so as to ensure the smooth progress of subsequent installation and debugging. Secondly, check and accept various civil facilities related to the induction furnace, such as checking whether the main dimensions in the layout are correct. Check whether the foundations, trenches and embedded parts required for the installation of various electrical equipment and main busbars meet the design requirements, and whether the induction furnace foundation, platform...
Infrastructure construction is underway in many countries now. In the construction industry, all kinds of steel are most commonly used. Our medium frequency induction melting furnaces are ideal for melting metal steel. As users look for an induction furnaces, there are a few things to keep in mind. Today we will give you a summary. Induction furnaces heat and melt metal faster than other options. When choosing an induction furnace, you need to consider how much metal you need to melt each day. The size you choose depends on how much metal you need to melt and how fast your production requirements are. First, when looking for an induction stove for sale, it’s important to know which size is best for you. A furnace that is too small will also end up holding you back and reducing production turnover. You usually have several options to choose from. For example, some small furnaces may be able to handle 1 to 2 kilograms of metal, while others can handle up to several tons of metal. Production speed requirements will greatly affect which furnace you buy. When choosing an induction stove, you should consider the noise factor. Some induction stoves are quieter in...
The thyristor intermediate frequency induction heating furnace means that the power supply of the intermediate frequency induction heating furnace adopts thyristor as the main frequency conversion component. Commonly used are thyristor full bridge parallel inverter variable frequency power supply or thyristor half bridge series inverter variable frequency power supply. An induction heating furnace using thyristor as an intermediate frequency power supply is often called a thyristor intermediate frequency induction heating furnace. The principle of thyristor intermediate frequency induction heating furnace: The intermediate frequency power supply of the thyristor intermediate frequency induction heating furnace is a thyristor frequency conversion device, which can convert the three-phase 50Hz alternating current to the heating frequency commonly used in the intermediate frequency induction heating furnace. In the SCR parallel inverter of the thyristor intermediate frequency induction heating furnace, the parallel compensation capacitor and the induction coil of the electric furnace form a self-oscillating circuit, which reduces the load of the electric furnace. Application of thyristor medium frequency induction heating furnace: used for overall or partial induction heating of steel rods, steel pipes, copper rods, aluminum rods, stainless steel and other metal workpieces. SCR medium frequency induction heating furnace heating material: carbon steel, alloy steel, Q235q,...
The intermediate frequency furnace will generate a large number of harmonics in the production process, and these harmonics are very harmful to transformers, voltage switches, and production safety. The harmonics of the intermediate frequency furnace will pollute the harmonics of the power grid, which will reduce the power transmission efficiency, cause insulation aging, and reduce the service life and other faults. The following will be edited by Hongteng to introduce the harm of the harmonics of the intermediate frequency furnace to the transformer. Harmonics increase the copper losses of the transformer, including resistive losses, eddy current losses in the conductors, and stray losses outside the conductors due to leakage flux. The harmonics also increase the iron loss of the transformer, which is mainly manifested in the increase of the hysteresis loss in the iron core. The worse the harmonics make the voltage waveform, the greater the hysteresis loss. Due to the increased loss in the above two aspects, the actual use capacity of the transformer should be reduced, or the harmonic content in the power grid should be considered when selecting the rated capacity of the transformer. In addition, harmonics also lead to the increase of transformer noise. The vibration...
In the production process, an intermediate frequency furnace is often used to smelt and heat metals. The intermediate frequency coreless induction melting furnace adopts an ultra-small intermediate frequency induction heating power supply, which uses the same electromagnetic induction principle as most intermediate frequency furnaces. However, the intermediate frequency coreless induction melting furnace is lighter in weight and can be moved. The following is a detailed introduction to the intermediate frequency coreless induction melting furnace. 1. Principle of intermediate frequency coreless induction melting furnace The core component of the intermediate frequency coreless induction melting furnace is a circular induction coil, commonly known as an induction coil, which is wound by a rectangular copper tube into a spiral shape. The intermediate frequency current is applied to the inductor, then the intermediate frequency alternating magnetic field is generated in the middle and around the induction coil. The alternating magnetic field in the induction coil cuts the metal placed in the induction coil, creating eddy currents on the surface of the metal. The eddy currents generated on the surface of the metal are very large, and such a large current is enough to melt the metal in an instant. Since the alternating magnetic field...
