Steel Mill

Produces Sheet Metal and Steel from Iron Ore + Coal.

Production recipe

Required inputs

6 Iron Ore units
6 Coal units

→

Output

4 Sheet Metal units
3 Steel units

Baseline: 121.67 cycles per default simulation year. Actual throughput depends on deliveries and operating conditions.

Restrictions

Economies: Temperate, Dry, Tropical, Subarctic

Storage

Iron Ore: 800 units (Input stock)
Coal: 800 units (Input stock)
Steel: 400 units (Output stock)
Sheet Metal: 500 units (Output stock)

Production

Recipe cycle frequencies accompany each production recipe. Actual output depends on available inputs, productivity boosts and plots.
Worker boost: at least 10 workers arriving by a passenger line within two default simulation years; productivity increases by 1.5–2.5× while the condition is met.
