Pearce, Jai and Schempp, E G (1981) Modern Developments in Engineering of Oxygen Steelmaking Shops for Bottom and Combined Blowing. In: International Symposium on Modern Developments in Steelmaking, February 16-18, 1981, NML, Jamshedpur.
The bottom blown basic oxygen steelmaking process was introduced and tested on low phosphorus hot metal in North America during 1971, The OBM/Q-BOP process proved to be an improvement over the top blown basic oxygen process in many aspects - capital costs, operating_costs, and process capabilities. Capital costs could be saved mainly because of much reduced Space requirements and deletion (particularly in the case of open hearth con-version) of extensive overhead material storage and han-dling systems due to the absence of lop lances and beca-use pneumatic material handling and bottom injection per-mitted replacement of gravity fed top additions. Operat-ing costs were reduced by a combination of high produc-tivity due to the capability of greater specific oxygen blowing rates and better product yields, both from charged-and additive materials.
