Crude Blast Furnace

The Crude Blast Furnace (previously just the Blast Furnace) is a multiblock added by Immersive Engineering. It must be arranged in a 3x3x3 solid cube (no hollow) of Blast Bricks to work. After it is arranged in that pattern, the player must right-click one of the center blocks with an Engineer's Hammer, then the multi-block is complete.





Usage
The Crude Blast Furnace works much like a normal Furnace, but it is only for making Steel and Slag (the latter as of version 0.7). Coal Coke or Charcoal can be used as a fuel. One Coal Coke is the perfect amount of fuel to smelt one Iron Ingot and create one Slag. Automating the Crude Blast Furnace via Hoppers or any sort of piping is not possible. For that, the player needs to build an Improved Blast Furnace, to which the Crude Blast Furnace is the precursor.

A Block of Coal Coke can be used as fuel, with 11.11% extra efficiency. A Block of Iron can be used instead of an Iron Ingot, although it doesn't have any extra efficiency except for time. To produce coal coke you may need to produce Coke Oven.
