The working principle of medium frequency induction furnace

Medium frequency induction furnace is a type of furnace that uses electromagnetic induction to heat and melt metal. It is widely used in the metallurgical industry for various applications such as melting, refining, and casting of metals. In this article, we will discuss the working principle of medium frequency induction furnace.

The working principle of medium frequency induction furnace is based on the principle of electromagnetic induction. When an alternating current passes through a coil, it generates a magnetic field around it. This magnetic field induces an electric current in the metal that is placed inside the coil. The induced current generates heat due to the resistance of the metal, which causes it to melt.

The medium frequency induction furnace consists of three main components: the power supply, the coil, and the crucible. The power supply generates an alternating current with a frequency of 1000 Hz to 10000 Hz. The coil is made of copper tubing and is wrapped around the crucible. The crucible is made of a refractory material that can withstand high temperatures.

When the alternating current passes through the coil, it generates a magnetic field that induces an electric current in the metal that is placed inside the crucible. The electric current generates heat due to the resistance of the metal, which causes it to melt. The molten metal is then poured out of the crucible for further processing.

The medium frequency induction furnace has several advantages over other types of furnaces. It has a high energy efficiency, which means that it can melt metal faster and with less energy than other types of furnaces. It also has a high melting rate, which means that it can melt large quantities of metal in a short amount of time. Additionally, it has a high degree of process control, which allows for precise control of the melting process.

In conclusion, the working principle of medium frequency induction furnace is based on the principle of electromagnetic induction. It is a highly efficient and effective method for melting metal in the metallurgical industry. With its high energy efficiency, high melting rate, and precise process control, it is an ideal choice for various applications in the industry.
