Steel Requires Incredible Amounts of Heat
The process to make steel involves mixing iron ore with carbon as well as other elements to give it strength. To do that, though, requires it to be in liquid form. And to turn iron into liquid requires heat. Lots of it. Steel furnaces crank up to 3,000 degrees Fahrenheit (1,650 degrees Celsius). That creates an atmosphere that’s essential to steelmaking. However, it’s not as simple as melting iron and carbon and calling it good. Instead, other processes have to happen.
