Guides for Smelting
All guides- Factorio furnaces per belt: 48 stone or 24 steel furnaces per yellow beltHow many stone, steel or electric furnaces fill a yellow, red, blue or turbo belt: 48 stone or 24 steel furnaces per yellow belt, plus the steel plate ratio.Read
- Factorio belt speeds: items per second for every beltYellow, red, blue and turbo belt throughput in items per second, per lane and with Space Age belt stacking, plus how many machines a belt feeds.Read
- Factorio Vulcanus casting ratio: foundries for molten iron and platesVulcanus foundry ratios: one molten iron foundry feeds 3.75 casting foundries, and 4 casting foundries fill a yellow belt of plates. Steel included.Read
- Factorio beacons in 2.0: diminishing returns and how many to useHow Factorio 2.0 beacons work: 1.5 effectivity divided by the square root of the beacon count, totals for 1 to 20 beacons, and the most per machine.Read
