The development of the medium frequency induction furnace and its superiority has injected new vitality into the casting production. The medium frequency furnace has the advantages of small size, light weight, high efficiency and favorable environment, which makes it a rapid replacement for coal-fired furnaces, gas furnaces, oil-fired furnaces and ordinary resistance furnaces. It is a new generation of metal heating equipment. The medium frequency induction melting furnace has high electrical efficiency and thermal efficiency, short melting time, less power consumption, less land occupation, lower investment, flexible production and easy implementation of process automation.
Comparing to other cast iron melting furnaces, it has attracting remarkable development in recent years and is widely used in cast iron production.
1 Induction Melting Furnace has wide frequency range from 1KHZ to 20KHZ, which can be adjusted according to the specific size of the workpiece or the depth of heating, with large range of adaptation. Considering the melting capacity, electromagnetic stirring, heating efficiency, noise and other factors to design an induction loop and matching compensation capacitor so that to determine the size of the output frequency.
2 With traditional medium frequency parallel-oscillating structure, induction melting furnace is simple load matching, high efficiency and high utilization of equipment.
3 Reverse process, which makes reliability increased greatly under the state of large power, and which makes the device developed greatly in high-power field so that to realize the 100% load.
4 High efficiency energy-saving: with the whole power range, high power factor and power efficiency, compare to silicon controlled medium frequency, it can save at least 20% energy.
5 Induction melting furnace is small size, light weight, completed models, and there is a large range to choose. It not only can be used in industrial production, but also available in small melting test in school institute.
6 Commonly used for melting steel, stainless steel, copper, gold, silver and other materials. There is a wide range of melting capacity, from a few kilograms to hundreds of kilograms. This induction melting furnace not only can be used in industrial production, but also available in small melting in school institute.
7 Medium Frequency melting furnace has a good performance in electromagnetic stirring, which can evenly melting the metal in temperature and structure aspect. It is conducive to scum, reduce impurities.
8 Compare to silicon controlled medium frequency, it can save at least 20% energy.
Medium Frequency Induction melting furnace is mainly composed of a power source, an induction coil and a crucible made of refractory material inside the induction coil. The crucible contains metal charging, which is equivalent to the secondary winding of the transformer.
When the induction coil is connected to the AC power source, an alternating magnetic field is generated in the induction coil, and the magnetic flux cuts the metal charging in the crucible. Then an induced electromotive force is generated in the furnace. Since the charging itself forms a closed loop, the secondary winding is characterized by only one turn and is closed. Therefore, an induced current is simultaneously generated in the charging, and when the induced current passes through the charging, the charging is heated to cause it to melt.
1 Fast melting speed, good power saving effect, small burning loss and low energy consumption.
2 With self-mixing function, melting temperature and uniform metal composition.
3 Good and friendly electric heating work environment.
4 Good start performance. Empty furnace or full furnace can reach 100% start.
