  • How Metals are Made Today I Found Out

    Iron ore is smelted in a blast furnace: Superheated air—up to 2,200°F—is "blasted" into the furnace, causing it to burn much hotter than it otherwise could. A typical blast furnace at a steel mill runs for 24 hours a day, 365 days a weeks, for up to 20 years, before it must be replaced. Pure steel is very susceptible to rust.
