SUMMARY:Scale production of pig iron with specified chemical composition in blast furnace operated with 100% pellets
DESCRIPTION:Stringent requirements of contemporary production of high-duty castings and special grades of steel lead to a new approach specific to basic burden material for foundry and special steelmaking which tends to use of virgin ferrous material with minimum impurities. Over a long period Kosaya Gora Iron Works (Tula, Russia) develops blast furnace technology for large scale manufacturing of pig iron with extended set of quality requirements in accordance with the above mentioned new approach. Along with the typical task to minimize content of conventionally detrimental sulfur and phosphorus in pig iron, technologists of Kosaya Gora must minimize content of manganese, titanium, vanadium and other tramp elements (up to 10 elements in all) in produced pig iron. Partially this task is solved due to application of ferrous burden with 100% pellets which are chemically purer than sinter. This paper describes peculiarities of production of high quality pig iron with precise qualitative properties through blast furnace route using state-of-the-art technologies and equipment.
