Presentation Transcript

  1. The Blast Furnace 1. A mixture of limestone, coke and haematite is added at the top of the blast furnace. 3. The carbon reacts with the hot air to form carbon dioxide. 4. The coke reacts with the carbon dioxide to form carbon monoxide. 5. The carbon monoxide reduces the iron ore to form iron and carbon dioxide. 8.Waste gases are removed from the blast furnace. 2.Hot air is ‘blasted’ into the blast furnace. 6. The iron, pig iron, collects at the bottom of the blast furnace to be tapped off. 1900°C 7.Impurities collect at the bottom in a layer, ‘slag’, and can be tapped off.
