Design features of modern induction furnaces
The design of the electric induction furnace provides for the presence of a melting and so-called induction furnace units. The inductor coil, through which the metal is smelted in induction furnaces, is made of copper. The inclination of the case is regulated by means of plungers which work on hydraulics.
The charge is heated in induction furnaces by creating an alternating magnetic flux in induction furnace units. In this case, eddy currents cause a constant movement of liquid metal inside the smelter, which contributes to a homogeneous mass. Crucibles of induction furnaces are made of acid or basic lining according to what metal is going to be smelted in it.
What is the main advantage of an induction melting furnace?
Due to the absence of an electric arc, it is possible to produce steel that will contain a minimum of carbon and gases.
Typically, a working induction furnace is used to make steel and alloys from alloyed waste. Another option involves the use of pure iron and ferroalloys. In addition, an electric induction furnace can be used to smelt non-ferrous metals such as copper and aluminum.
It can be quite hot in a room where melting furnaces are constantly operating. Therefore, for the safety and comfort of the personnel servicing the working induction furnace, an air cooler is a necessary element. At the same time the furnace and the conditioner should function at the same time.
