When poured it is called pig iron. It must be heated anew and treated with carbon to obtain steel. Pig iron is usually how the metal is transported to plants not built to extract a metal from ores. Rail expenses are cheaper too. Pig iron
is common ballast for ocean vessels with or without cargo.

Iron
This has to be worked, purified and refined, but that's how they get the iron out of the ore.
Steel is produced by adding a specific amount of carbon to this purified iron.
