- The basic oxygen furnace (BOF) process is a method of primary steelmaking that converts raw iron into steel. Here are the steps involved1234:
- The charge (molten blast-furnace iron and scrap) is dumped into the furnace.
- An oxygen lance is lowered, and pure oxygen is blown into the furnace at high pressure.
- The oxygen reacts with the carbon and impurities in the molten iron, reducing the carbon content.
- When the desired carbon level (up to 0.9%) is reached, the process is finished.
- Steel is tapped from the furnace into a steel ladle, and slag is removed.
- Waste gases containing carbon monoxide are captured and used for power generation.
