Luoyang HongtengIntermediate frequency induction furnace
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...
The induction furnace we produce, the heating principle is the use of electromagnetic induction. Therefore, electricity consumption is a very important issue, which directly affects the output of the production line. Generally speaking, electric furnaces with fast melting furnaces are more energy efficient than slow melting furnaces. The same set of equipment, the speed is slower than the power consumption. At the same time, attention should be paid to the timing and compactness of charging, the size of the furnace, etc. All these points can meet the optimal power consumption at the same time. Furnace charging should take into account the ammeter, make the power supply as stable as possible, and maximize the output power of the power supply. Remember that the temperature of the hot metal should be accurately controlled and the temperature of the electric furnace should not be too high or locally too high. This is not good for power consumption and the life of the lining. A good forehearth worker saves electricity and increases efficiency. Select the appropriate furnace power supply. If the electric stove is too large or too small, it may increase the power consumption. The same large electric furnace can quickly save electricity,...
Steel shell induction intermediate frequency furnace is one of our main heating equipment. As an industrial furnace for heating metal, the overall stability of the steel shell furnace is good, firm and not easy to damage, and strong in safety. Our electric furnace generally adopts the principle of electromagnetic induction, so when working, the noise of the furnace body is very low and the working environment is good. The design of the furnace table above the horizontal height makes the charging more efficient. The intermediate frequency electric furnace is carefully designed according to the different requirements of various metal smelting. Users can choose various specifications of induction coils for intermediate frequency electric furnaces, and rationally choose the wall thickness and specifications of copper pipes, so as to improve the utilization rate of electric energy. The exquisite coil design makes the power conversion efficiency, selects the correct cross-sectional shape of the coil for different applications, and also provides more melting energy for thick-walled induction coils. The coil of the intermediate frequency electric furnace is lengthened, which can cover more than 60% of the magnetic field around it, reducing heat loss. The solid coil support design eliminates the possibility of inter-turn short...
