About this build

48 electric furnaces matched to one full red belt of ore, input and output on opposite sides. Every setup in this series is calculated for the maximum throughput of its input belt.

A clean mid-game smelting line that needs only ore and power. Built in Factorio 1.1 by its author; 2.0 converts it when you import it, so check it once after placing.

Before you place it

  • Clear a space of at least 73 × 13 tiles.
  • It works in the base game without Space Age.
  • It has 48 crafting machines, so connect enough power before you switch it on.
  • It is large: construction robots will place it much faster than building by hand.
  • It was made in Factorio 1.1; the game converts it when you import it, so check it once after placing.
