Crude Blast Furnace



The Crude Blast Furnace (formerly Blast Furnace) is a 3x3x3 multiblock furnace added by Immersive Engineering that alloys Iron with Coal Cokes to produce Steel.

Construction involves arranging 27 Blast Bricks into a cube and using an Engineer's Hammer on the front face to complete the structure

Usage
The Crude Blast Furnace produces Steel Ingots and Slag by smelting Iron Ingots with Coal Coke or Charcoal as fuel. One Coal Coke burns long enough to smelt one ingot, which produces one Slag piece. A Block of Coal Coke smelts 10 ingots (so it's 11.11% more fuel efficient). A Block of Iron smelts in less time than 9 single pieces.

Coal Cokes come from roasting Coal inside a Coke Oven.

Hoppers, Conveyor Belts and other item transporters can't hook up to the Crude Blast Furnace, but they can with the Improved Blast Furnace.
