That heats up the furnace to 2300 degrees, the temperature at which iron ore melts. When sufficient hot metal has formed at the bottom of the furnace, we drill open the furnace and tap the iron. The hot metal is collected in torpedo-shaped train waggons and is then ready for transport to the BOS (Basic Oxygen Steelmaking) plant next door.
