Figure 1. Pie chart to show realtive amounts of steel produced by EAF and BOS methods. The numbers are in millions of metric tonnes in 1997.
|Route 1 Basic Oxygen Steelmaking (BOS)|
|The hot metal from the Blast Furnace contains up to 4.5% of carbon. |
Steelmaking reduces the carbon content to a level that matches the customers requirements. This is often less than 0.1%. Basic Oxygen Steelmaking (BOS) makes steel from Blast Furnace iron and small amounts of scrap metal.
