Main features of induction melting furnace

1. The power supply adopts all-solid-state Siemens IGBT frequency conversion module technology, replacing traditional low-end products with unstable quality and high energy consumption such as thyristors, electron tubes, and transistors.

2. Comprehensive protection functions such as: overcurrent, water shortage, overheating, overvoltage, short circuit, and phase loss protection greatly improve the reliability of the equipment and facilitate equipment maintenance.

3. The smelting furnace is small in size and covers an area of ​​less than 1 square meter; it is light in weight and easy to move from 20 kg to 150 kg; it can be used without debugging, connecting to electricity and water; the machine operation is very simple and can be done in just one minute; it is suitable for factory production. It is suitable for small family workshops and small sample melting experiments in schools/research institutes; one furnace can melt all metals.

4. 24-hour uninterrupted smelting capability, saving about 90% energy than traditional medium frequency thyristors, coke ovens, gas furnaces, oxy-acetylene flames, oil furnaces, and salt bath furnaces.

5. It has the electromagnetic stirring function to make the melt more uniform, which is beneficial to dross and reduces impurities, making the melt or castings brighter and free of shrinkage and porosity.

Smelting principle of the intermediate frequency smelting furnace: The power supply adopts all-solid-state Siemens IGBT frequency conversion module technology, and adopts the principle of magnetic field induction eddy current heating. It uses current to pass through the coil to generate a magnetic field, and heats the metal through the electromagnetic eddy current induction generated by the metal itself. The metal is instantly heated through the crucible container. Start melting, melt the metal into liquid, and then carry out processes such as smelting, refining, purifying, and then casting and molding using various molds. Compared with coke furnaces, gas furnaces, oil furnaces, and ordinary resistance furnaces, the melting speed is faster, and it consumes less energy and saves energy. Environmentally friendly, small in size and easy to operate.

The equipment structure of the intermediate frequency melting furnace:

1 As shown in the figure and photo below: the most basic components of the intermediate frequency power supply, capacitor box and smelting furnace.According to different application requirements, it may also include infrared thermometers, temperature controllers and other devices; the melting furnace is divided into three types: tip-over melting furnace, ejection melting furnace and fixed melting furnace.Tip-over smelting furnaces can be divided into hand-operated mechanical tip-over furnaces, electric tip-over furnaces and hydraulic tip-over furnaces according to the tip-over method.  2  Normally, a coaxial cable is used to connect the intermediate frequency power supply and the capacitor box, and a water-cooled cable is used to connect the capacitor box and the smelting furnace.

Main smelting furnace specifications and heating capacity:

The heating capacity of each melting furnace is listed in the following table. When the furnace is cold, the melting time per furnace is 50--60 minutes. When the furnace is hot, the melting time per furnace is 20--30 minutes.
