Foundry

The Foundry is a building that smelts two ore resources into alloy ingots that can then be further processed. It is unlocked at Tier 4 - Steel Processing.

Smelting
The Foundry is used exclusively for combining multiple ore resources into a single resource. It cannot be used for smelting single ore resources into single ingot resources nor does it behave like a tier 2 smelter.

Tips
As steel production consumes a lot of iron ore and coal, it is advised to research Alternative recipe: Steel Ingot as soon as possible.

Trivia
As the output connector is not at the center, the building guide does not work on the output side of the foundry. Engineers are advised to align mergers/splitters manually.
