The history and advantages of induction furnace
Heating metals is the easiest way to change their shape. After heating, metals can be processed into various shapes and functional products, and then applied to our lives.
The first heating method is to create a high temperature environment by burning fossil fuels, and then heat the metal in this environment. In this way, it takes a long time to complete the heat treatment of the metal.
In the 1920s, Faraday discovered the principle of electromagnetic induction, which was then used by humans to heat metals.
The alternating current is transmitted to the induction coil, and the magnetic field is generated 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 itself.
Using this principle, people have invented a new equipment that can smelt metal more quickly, which is an induction furnace.
When the induction furnace heats 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.
Therefore, induction furnaces are now very popular in the market and are widely used in industrial manufacturing.
