Steel comes from an Athanor

Supply an Athanor with 1 Iron Ingot and 1 Coke Powder for a Steel Ingot attempt. The base craft takes 4 seconds; the successful output is 1 Steel Ingot.

The base Athanor recipe has a 75% failure rate. A failed outcome returns 1 Iron Ingot, so plan the line around both Steel production and returned Iron.

02

Keep the two outcomes separate

  1. Feed the Iron Ingot and Coke Powder inputs to the Athanor recipe and allow for its failed attempts when planning Steel output.
  2. Preserve the returned Iron from failed Athanor crafts for reuse, and route successful Steel Ingots toward the component line.
  3. For Steel Gears, use a Processor. Its recipe converts 1 Steel Ingot into 1 Steel Gear in 16 seconds.
03

Understand the Iron output

Why is the Steel line returning Iron Ingots?
Iron is the failed outcome of the Steel recipe. The Athanor uses Iron Ingot and Coke Powder, and its base failure output returns an Iron Ingot instead of producing Steel.
Which machine makes Steel Gears from the finished ingots?
Route Steel Ingots into a Processor set to Steel Gear. Each craft uses 1 Steel Ingot and produces 1 Steel Gear with a base recipe time of 16 seconds.
