Vacuum induction melting
Okay kiddo, do you know what a vacuum is? It's like a really empty space with no air in it. Now imagine a big machine that heats up a metal until it becomes liquid, but instead of doing it in the air, it does it in a vacuum. And it's called vacuum induction melting!
Here's how it works: First, we put pieces of metal in a special container called a crucible. Then we put the crucible inside the vacuum chamber of the machine. Next, the machine uses a special process called induction to heat up the metal. This means we use some special magnets to make electricity flow through the metal, which heats it up quickly.
But why do we do this in a vacuum, you ask? Well, when metal is heated up to really high temperatures, it can react with the air around it and become less pure. By doing it in a vacuum, we make sure the metal stays really pure and doesn't react with anything else.
Once the metal is melted, we can use it to make all sorts of things, like new alloys for airplanes, or really strong steel for skyscrapers. It's a really cool process that helps us make strong and pure metal to build things with!
