Continuous Steelmaking Unit

Continuous Steelmaking Unit


a general designation for various types of steel smelters designed for continuous operation. With continuous, controlled supply of charge materials (molten pig iron, steel scrap, metallized pellets, solid oxidizing agents, and fluxes) and of gaseous oxygen for the oxidation of metal impurities, the production of finished steel can also be carried out continuously.

Reactor (conversion), oxygen-jet, channel-type, and vat-type units are distinguished on the basis of design and working principle. Units are also categorized as one-step, two-step, or multi-step, depending on the number of individual stages, and as gas-fired, electric, or pure-oxygen units without additional heating, depending on the type of energy used. In comparison with batch units, continuous steelmaking units will have several significant advantages, including higher efficiency, lower specific capital investment, greater consistency of quality for the steel produced, and ease of control of the production process.

As of 1975, the development of continuous steelmaking units had not progressed beyond the pilot-plant stage.
