Results From Recent Oxygen Converter Revamping Projects

Abstract

Steelmakers are facing challenging times due to production overcapacity, volatile markets and stricter environmental regulations. As a consequence investments are focus in modernization and upgrade of existing capacities these days. Primetals technologies has realized a wide range of revamping and upgrade projects in the recent past; selected projects highlighting the benefits from such upgrades will be shown. At Ruukki, SSAB, Finland three converters have been exchanged and improvements of the metallurgical process like yield and lining lifetime have been achieved. At AM Mittal Temirtau, Kazakhstan a Vaicon Measurement Manipulator was successfully implemented and probe taking and measurement at the converter is running now without any manual operator interference. The last project presented is the replacement of two BOF converters at AM Dabrova Gornica, Poland.
