Electric furnace — Factorio Production Calculator
Electric furnace is crafted in the assembling machine in 5 seconds, producing 1 per craft from 10 × Steel plate, 5 × Advanced circuit, 10 × Stone brick. At 60 per minute you need 10 assembling machines, and the chain behind it draws on 5 raw resources: petroleum gas, iron ore, copper ore, stone, coal.
Production chain for 60 Electric furnace / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Iron plate | 3,600 | 192 | Furnace |
| Copper cable | 3,000 | 25 | Assembling machine |
| Copper plate | 1,500 | 80 | Furnace |
| Steel plate | 600 | 160 | Furnace |
| Electronic circuit | 600 | 10 | Assembling machine |
| Plastic bar | 600 | 5 | Chemical plant |
| Stone brick | 600 | 32 | Furnace |
| Advanced circuit | 300 | 60 | Assembling machine |
| Electric furnace | 60 | 10 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Petroleum gas | 6,000 |
| Iron ore | 3,600 |
| Copper ore | 1,500 |
| Stone | 1,200 |
| Coal | 300 |
Machine counts are not rounded up. Add a little headroom in game — belt throughput and inserter speed usually mean you want 5-10% more than the exact number.
Electric furnace recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 5 s | 1 | Steel plate × 10, Advanced circuit × 5, Stone brick × 10 |
What the whole chain needs
60 electric furnaces per minute pulls in 8 intermediate products, and the whole tree comes to 574 machines across 3 machine types, fed by 5 raw resources. The table above already sums demand across every branch — if copper cable is used by two recipes, you see the total, not one of them.
Belt check: the busiest input here moves 6,000 per minute, which is 6.67 of a yellow belt's 900 per minute. Above 1.0 and you need a second belt (or a faster tier) before the machines themselves become the limit.

FAQ
How many assembling machines do I need for 60 electric furnaces per minute?
10 assembling machines. One at standard speed produces 6 per minute, so 60 ÷ that number is the count. The calculator above rounds nothing — add 5-10% headroom for belt and inserter losses in a real factory.
How much raw ore does electric furnace take?
At 60/min the chain consumes 6,000 petroleum gas per minute, 3,600 iron ore per minute, 1,500 copper ore per minute and 2 more. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Is electric furnace needed for science packs?
Yes — it goes directly into Production science pack. Open the science pack page to see the demand that lands on this recipe.
