Just starting using these on a new map and I can't smelt steel in the basic furnace. Is that intentional?

EDIT: Nevermind! I was so eager to test these things out I forgot to research Steel Processing....

This mod is great. This means I can start setting up smelting areas without having to run coal lines! Just out of curiosity, I'd be interested to know how much this increases the coal usage of a factory compared to using a coal-burning furnace.
