Aperam is a global player in producing of stainless, electrical and special steel qualities. The plant in Timoteo Brasil is equipped with one AOD-converter for stainless steel and one MRPL-converter for special steel production. The MRP-L converter is almost in operation for 20 years. In order to improve production Aperam decided to install a new converter with increased reaction volume equipped with Danieli state of art technology. This paper describes the major changes and improvements of the new converter installation which are based on:  New trunnion ring with welded pins  Converter with increased volume from 56 m³ to 62.2 m³, this is a plus of 11 %  Maintenance free converter suspension system based on the DANI-ELLA horizontal and lamella type vertical elements  Maintaining the existing tilting drive, bearing size, bearing housings and dog house  Avoiding welding on site by introduction of a flange connection in the barrel section of the vessel shell  Optimized slag shields  Keeping the delivery time to a minimum Aperam is a global player in producing of stainless, electrical and special steel qualities.
