I 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.

I 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.
