Basic Oxygen Steelmaking Simulation – steeluniversity

Description. The aim of this simulation convert approximately 250 tonnes of hot metal and scrap into steel. This is achieved by blowing oxygen into the melt to cause a decarburization in the melt which lowers the carbon content to between 0.01 wt% and 0.4 wt%.

Creating Steel | HowStuffWorks

However, most modern steel plants use what's called a basic oxygen furnace to create steel. The advantage is speed, as the process is roughly 10 times faster than the open-hearth furnace. In these furnaces, high-purity oxygen blows through the molten pig iron, lowering carbon, silicon, manganese and phosphorous levels.
