The "basic oxygen furnace" is commonly used in the production of steel and is also referred to as the BOS furnace. It's a technology that uses pure oxygen to produce high-quality steel. Synonyms for the term include the Linz-Donawitz furnace (LD), oxygen converter, and LD converter. This furnace uses scrap metal and ensures a high level of control over the composition of the recycled steel. Other names used to describe the BOS furnace include the Bessemer process, Siemens-Martin process, and the open-hearth furnace. These are all variations of the advanced technology used to create high-strength, corrosion-resistant steel products that are used in various industries around the world.
