When and how to use bessemer and rotor converters?

Bessemer converters are used in the steelmaking process, specifically for converting molten pig iron into steel by blowing air through the molten iron to remove impurities. They are typically utilized in the early stages of steel production, especially during the late 19th and early 20th centuries. Rotor converters, on the other hand, are employed in electric arc furnace operations for refining steel. They are designed to enhance the mixing and refining process by utilizing a rotating mechanism, allowing for better temperature control and improved material properties.
