Basic oxygen furnace (BOF) Equipment (with a basic that is non-acid lining) developed from the principles of the historical Bessemer converter for turning run-of-furnace iron into steel with a controlled content of carbon. In the BOF oxygen is injected into the molten metal rather than the air used in the nineteenth-century process.
