Abstract

Aperam is a global player in producing of stainless, electrical and special steel qualities. The steelmaking plant in Timoteo Brasil is equipped with one AODconverter for stainless steel and one MRPL-converter for special steel production. After almost 20 years of operation Aperam decided to exchange the existing 80 t MRP-L converter by a new one including a new trunnion ring and a state of the art suspension system. Due to an optimized design the inner volume of the new converter could be increased which comes along with improved production. A special feature is a flange connection in the barrel section of the converter. This allowed to avoid any critical site welding and the time between shut down of the old and cold commissioning of the new converter could be done with 17 days only.
