I was gonna do something like this once. In real life, steel is created through a variety of methods, but the medieval method is through a bloomery. Essentially, hot but still solid iron absorbs carbon from charcoal to become steel.

To make this work with a smeltery, I would change the GUI a bit for the faction-specific ones so that it can use charcoal/coal as 'fuel' as well as lava. If you had charcoal/coal as 'fuel', then smelting iron ore or iron ingots would create the steel of the respective faction.

This method is more realistic than liquid coal, and also allows you to use solid fuels in a smeltery.
