First of all, induction heating of metal is a process that occurs to the metal directly by putting the metal in a ceramic or graphite crucible. In that cubicle, we use the induction heating of metal that allows the metal to melt with high accuracy and high purity.
This melting that happened as a result of the induction heating of the metal can take place in a vacuum or under an inert atmosphere for metals with high reactivity.
The benefits of the induction heating of metal:
Well, induction heating of metal is used as a method for heat treatment for some kind of metal. There are many applications for induction heating of metal to give new properties to the induced metal.
An example for those applications:-
Induction hardening of steel:
It is the most common type in the industrial application. Basically, the induction soldering is an application for induction heating of metal. We do this process to make a metal joint between its components and the induction annealing.
Basically, the purpose of this process is to the steel to soften a particular part. The induction heating of metals process can produce densities with the high power.
Consequently, this will help with the interactions to reach the temperature you desire in a short time. This will give you complete control on the heating pattern with the used magnetic field. Moreover, this control manages the distortion and damage possibilities that could occur.
This ability can be exploited in the process of hardening so that we can produce parts of metal with different properties.
For example, you can use induction heating of metal in the production of parts of the metal with better properties. You can produce metals with higher corrosion resistance, while retaining the hardness of the original structure of the metal.
You need to select 3 factors to control the depth at which the induction process takes place.
The 3 factors are:
- The amount of energy density,
- Reaction time
- Induction frequency.
So, the need to produce particular inputs for many purposes sets different restrictions on the flexibility of induction heating of metal.
Typically, this can cost lots of money and requires high-density current mobilization in small copper reactors, which can demand”fitting copper” and specialized engineering.
