blast furnace
Industrial iron smelter
A blast furnace is a tall industrial furnace for smelting iron ore, where intense heat is generated by forcing hot air through the burning fuel.
The name comes from this continuous blast of air.
Blast furnaces operate continuously for years, producing molten iron that flows from the bottom while slag is removed separately.
