Required modulesFactory

The Blast Furnace is a multiblock structure added by Railcraft. This structure is used to turn Iron into Steel. The Blast Furnace will only take Coal Coke, Charcoal, and Thaumcraft Alumentum as fuels, requiring 1 Coal Coke per Ingot, 0.5 Alumentum per Ingot, 2 Coal per Ingot, or 4 Charcoal per Ingot.


Blast Furnaces cannot be built directly adjacent to one another; there must be a gap between them, or other non-Blast Furnace Brick blocks. It can be built directly adjacent to other multiblock structures, such as the Coke Oven.
