basic oxygen process

Another, though less common, oxygen steelmaking system is a bottom-blown process known as the Q-BOP (quick-quiet BOP) in North America and the OBM (from the German, Oxygen bodenblasen Maxhuette, or “oxygen bottom-blowing furnace”) in Europe. In this system, oxygen is injected with lime through nozzles, or tuyeres, loed in the bottom of the vessel.

Steelmaking - Wikipedia

Steelmaking is the process of producing steel from iron ore and/or scrap.In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel.

CO2 Utilization in the Ironmaking and Steelmaking Process

Bottom-Blowing Carbon Dioxide in the BOF In the 1970s, the scholars began to study bottom-blowing CO2 in the converter steelmaking process and found [9] that CO2 can participate in the bath reaction, and its bottom-blowing agitation ability is stronger than that of Ar and N2 , when compared with blowing N2 /Ar from the bottom, which is an easy

Feb 25, 2015· When oxygen steelmaking began replacing open hearth steelmaking excess scrap became available at low cost because the BOF melts less scrap than an open hearth. Also for fully devel- oped countries like the United States, Europe and Japan the amount of obsolete scrap in relation- ship to the amount of steel required increased, again reducing the
