ArcelorMittal Tubarão commissioned Siemens VAI Metals Technologies to renovate blast furnace 1 at its Tubarão Works in Brazil. The blast furnace, which has an internal volume of 4,415 cubic meters, is rumored to be the world’s longest-serving to date at almost 27 years old. It is reported to have produced more than 85 million metric tons of hot metal since it came into operation in November 1983. The project is expected to cost approximately $12 million. Siemens will dismantle and rebuild the blast furnace within an 80-day shutdown period.

Siemens will also be responsible for the basic and detailed engineering, methodology and planning, and for coordinating reconstruction and commissioning. ArcelorMittal Tubarão, which has an annual capacity of 7.5 million metric tons of crude iron, produces semi-finished products in various grades of steel.
