The Blast Furnace is a Tier 4 machine that requires at least one Casting Basin connected using Casting Pipes at the center of the base of each. It will draw ore from any connected storage hopper, and is significantly faster at smelting T4 ore than the Arc Smelter Upgrade, smelting T4 ore at a base rate of 20 per minute, but half as efficient, consuming 32 rather than 16 units of T4 ore per bar.
9x Blast Furnace components requires:
- 16x Chromium Bar (112 total)
- 16x Molybdenum Bar (112 total)
Build in a 3x7x3 configuration.
