3x3x4 Blast Furnace

The Blast Furnace is a 3x3x4 structure made out of Blast Furnace Brick which, like the Coke Oven, is hollow in the middle except on the Blast Furnace two of the blocks are hollow in the middle. It is not suggested to stand in the middle of the hollow portion when placing the last brick, as lava appears in the hollow portion.

The Blast Furnace is used to turn Iron Ingots into Steel Ingots which are essential in the RailCraft mod.

The Blast furnace only accepts Charcoal (four per Iron Ingot) and Coal Coke (two per Iron Ingot) as fuel.

Total material needed to build a blast furnace: 

• 9 Magma Cream
• 36 Nether Brick
• 36 Soul Sand

You can pipe (or use carts to add) iron into the top, the fuel you are using into the bottom, and remove the steel from any side.

Efficient Usage

It is far more efficient to stoke the Blast Furnace using Charcoal, when using EE.

Coal(128 EMC) to Charcoal(32 EMC) yields four times as much Charcoal as Coal, but the Blast Furnace requires only twice as much Charcoal as Coal Coke. This way you'll need only half as much Coal to create the same amount of steel, compared to using Coal Coke created in a Coke Oven. It's also much faster. The loss is that you won't gain the creosote oil that's produced when turning the Coal into Coal Coke.
