What is an induction furnace?

Induction furnace is an electrically operated furnace used for metal melting. It creates heat using an alternative current solenoid coil, otherwise known as electromagnetic induction. They are most often found in the metal industry scrap.

The induction furnace was first invented in 1877 in Italy. The first use of Pec was in 1927 in Britain. Until the Second World War, when the need to occupy aluminum grew significantly, the induction furnace spread to a wider use.

Electromagnetic induction is a process that allows induction furnace to function. It was first discovered in 1831 by Michael Faraday. During induction, an electric current passes through a metal coil that creates a magnetic field. When the metal is introduced into the magnetic field, the electric current passes through the metal and causes it to heat. The most common use of this process is the manufacturer of rice. The pot, which contains rice, is located at the top of the metal coil and heats them again.

There are two types of induction furnaces. The first is unstable and the second withE calls a channel. Both are used at the beginning of the 21st century.

The

induction furnace has copper coils that are protected by a steel and magnetic label and maintained cold water circulating from a special cooling tower. Above the coils is placed a layer of refractory or difficult to melt the material and heat up to the desired temperature. Above the refractory is a crucible, which is a melting container made of heat -resistant material. The metal to melt is located inside the crucible and the heat produced by the electromagnetic charge melts the scrap.

The channel induction furnace can also be called a basic induction furnace. It works very similar to a non -coder furnace, except for the addition of a heated core. The channel furnaces were originally used as molten metal holders, but were found to be useful for melting metals with a lower melt temperature.

both types of induction furnaces create a natural mixing movement when KO isin molten. The draft of magnetic fields and electrical currents causes materials to swing in different directions. This mixing is necessary to maintain metal integrity. The helpless furnace creates violent mixing while it is known that the channel has less turbulence on the surface.

After melting, the molten metal poured into a mold. Some pouring methods are fully operated by human hands. Others are mechanical with human intervention while others are fully automated. Mechanical systems are more efficient for large -scale projects, while multiplication methods are more suitable for low -volume production lines.
