Steel furnace

Interface

Steel Furnaces are the second-tier of furnaces. Compared to Stone Furnaces, they smelt at double the speed and therefore are a more efficient use of the given fuel. Steel Furnaces are comparable to Electric Furnaces in terms of smelt speed, however the latter can make use of modules (as well as Electricity) to further enhance the furnace's capabilities.

Placement

'Steel Furnaces can replace Stone Furnaces without mining the Stone Furnace first. This can be done by clicking on the Stone Furnace with the Steel Furnace in the players hand.
