Iron Ore Blast Holes

THE BLAST FURNACE - IRON PRODUCTION

They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron. The stock level is constantly 'topped up'. Molten iron ore is 'tapped' at the bottom of the blast furnace, poured into the iron ladle and removed for use. The slag is removed at the tap hole.
