Season 3, Episode 11
Making steel is complicated, but Slab Hauler knows everyone at the steel mill and has offered to take us on a tour. We’ll meet a ladle crane, an electro-magnetic crane, a turbo train and even a fire quencher. It takes a whole team of special machines to produce steel. Making steel is a lot like baking! Dozer works with Scraper to send coal off to the coke ovens where it is turned into coke. Coke is put into a blast furnace along with iron ore and limestone, and that makes iron. Iron goes into the steel mill where it is mixed with scrap in another oven. Now turn up the temperature and … presto! It turns into big, red-hot slabs of steel. Moving the slabs of steel is Slab Hauler’s job, and he loves to show his strength by picking up stacks of them all at once.
