> then refine it from iron oxide into pure iron and fortify it with small amounts of carbon. It’s a complex process that emits carbon at different stages. Some emissions come from the heating process, which usually involves burning a heat-refined form of coal called coke. A bit of the carbon from the coke gets dissolved into the iron, turning it into steel.
Very incorrect. It's not even a highschooler level mistake.
- etskinner 5y agoI worked in a steel mill a while back. While I agree it's incorrect, I would say that the average high school student knows next to nothing about making steel. Here's how we made it: Take pig iron, put it into a Basic Oxygen Furnace. Add flux and inject supersonic oxygen. This removes impurities and carbon from the pig iron turning it into steel. Transfer to a huge crucible. Add any alloying elements, and cast it into slabs using a continuous slab caster.
