Features and advantages of Mediate-Frequency Induction Melting Furnace

The intermediate-frequency electric furnace uses an intermediate-frequency power supply to establish an intermediate-frequency magnetic field, which induces eddy currents inside the ferromagnetic material to generate heat, thereby achieving the purpose of heating the material.

The intermediate-frequency electric furnace uses a 200-2500Hz intermediate-frequency power supply for induction heating, melting and heat preservation.

Medium-frequency electric furnaces are mainly used for smelting carbon steel, alloy steel, and special steel, and can also be used for smelting and heating non-ferrous metals such as copper and aluminum.

Characteristics of medium frequency induction melting furnace

The melting capacity of an induction melting furnace ranges from 1KG to 250KG. Mainly through the crucible container, the precious metal is heated instantly, and then smelting, purification, casting and other processes are carried out. The following are some of the main features of medium-frequency induction melting furnaces:

The medium frequency induction melting furnace has a good electromagnetic stirring effect, which is beneficial to the uniform temperature and structure of the melted metal, is beneficial to slag removal, and reduces impurities.

Medium frequency furnace frequency range: high frequency 20-50KHZ, medium frequency 1-10KHZ. The induction coil and supporting compensation capacitor can be designed taking into account factors such as melting amount, electromagnetic stirring effect, heating efficiency, noise during operation, etc. to determine the output frequency.

Compared with silicon-controlled medium frequency, induction melting furnace saves energy by at least 20%.

Induction melting equipment occupies a small area and is lightweight. The melting capacity of induction melting furnaces ranges from a few kilograms to hundreds of kilograms.

The choice is wide. An induction melting furnace is suitable for small-batch melting in factory production, schools, scientific research institutes, or enterprise content testing.

Advantages of medium frequency induction melting furnace

Induction melting furnace mainly converts metal into liquid by applying high temperatures. Its heating capabilities and advantages are as follows:

High-frequency melting furnace: single melting time 1-5 minutes. Suitable for smelting small amounts of metal 1-5KG, smelting iron, stainless steel, gold, molybdenum: 1-2KG.

Medium frequency melting furnace: When the furnace is cold, the melting time per furnace is 40-50 minutes; when the furnace is hot, the melting time per furnace is 20-30 minutes.

Induction melting furnaces are suitable for melting large amounts of metal or production, and metals with low melting points melt faster.

In addition, the advantages of intermediate-frequency furnaces are as follows:

The maximum temperature of the intermediate frequency furnace can reach 1700-2000 degrees.

The intermediate frequency furnace has fast heating speed and constant temperature after heating.

The intermediate frequency furnace is simple to install, safe to operate, environmentally friendly and energy-saving.

The intermediate frequency furnace is light in weight, small in size and has high storage efficiency.

Medium frequency furnace safety protection: equipped with overvoltage, overcurrent, overheating, water shortage and other alarm devices, and automatic control and protection.

Medium frequency furnace input voltage: three-phase 380V.

Conclusion

A medium frequency induction furnace is a three-phase power frequency alternating current, rectified into direct current, and then the direct current into the adjustable current, supply through the capacitor and induction coil of alternating current, in the induction coil to produce high-density induction furnace.

The equipment has the advantages of small volume, light weight, high efficiency, low power consumption, fast melting and heating speed, easy control of furnace temperature and high production efficiency. It is easy to operate and suitable for various casting processes.
