basic oxygen process




The basic oxygen process, also called the Linz-Donawitz process, is a widely used process for making steel. The basic-lined converter has no tuyeres; a stream of pure oxygen at high pressure is blown through a lance onto the surface of molten pig iron (low in phosphorus) mixed with scrap to help remove impurities. Developed in Linz and Donawitz, Austria (1952), it has superceded the Bessemer process and open-hearth process.
