In the 1920s, Faraday discovered the principle of electromagnetic induction, which was then used by humans to heat metals. It is the induction heating furnace.
Before this, people created a high-temperature environment by burning fossil fuels and then putting the metal in it to heat. In this way, it takes a long time to complete the heat treatment of the metal.
Heating metals is the easiest way to change their form. The heated metal can be processed into various shapes and functional products and then applied to our lives.
Electromagnetic induction can transmit alternating current to the induction coil, which generates a magnetic field in the coil.
The magnetic field directly penetrates the metal in the coil, making the electrons inside the metal active, thereby achieving the effect of rapidly heating the metal.
Using this principle, people have invented new equipment that can smelt metal more quickly. That is the induction furnace.
When the induction furnace heats the metal, it does not need to burn traditional fossil fuels and does not emit any toxic substances. The whole working process is clean and pollution-free, which is very helpful to protect the environment.
More importantly, when the induction furnace is working, there is no open flame and no noise during the whole process, which greatly improves the working conditions of employees and makes their work safer.
Induction furnaces are now very popular in the market and are widely used in industrial manufacturing.

Heating temperature is between 200-1400 degrees.
