Steelmaking 101 - Conklin Metal Industries

There are two ways to make steel—in a Blast Furnace (BOF) or in an Electric Arc Furnace (EAF). In the U.S., approximately 75% of steel is made using the EAF method, and 25% is made by integrated mills using a basic oxygen furnace (BOF). Worldwide, however, that ratio is reversed with only about 35% of the steel made using EAF technology.

Blast Furnace | Minecraft Wiki | Fandom

A blast furnace is a utility block that generates in a village's armorer houses. A blast furnace can be used as a faster alternative to smelt ores. It can smelt ore at twice the speed of a furnace, but it will use up fuel twice as fast, and it can only smelt ore-related blocks. They will give less experience to the player when they collect the smelted item. If a village has a blast furnace but
