steel mill - Michigan State University

2021.1.21  In 1709, he discovered that coke, a baked coal that burns hotter than wood or coal, could be used to efficiently smelt iron, then heat it to the 2,800F that renders it castable. With its 2-4.5% carbon content, cast iron is more brittle and rust-prone than its low-carbon (less than 0.03%) hammer-forged cousin, wrought iron.
