H.E.S. Hennigsdorfer Elektrostahlwerke GmbH (H.E.S), a company in the Riva Group, has issued Primetals Technologies with the final acceptance certificate for a modernized, turnkey bar mill in Hennigsdorf, in the German state of Brandenburg. The modernization project included replacing two existing stands in the roughing mill with new Red Ring stands, which do not have housing. This solution requires less space and has greater rigidity to enable consistently narrow product tolerances to be achieved. The new stands also have larger rolls. This increases the stability of the process and allows multi-strand operation. Primetals Technologies had received the order in May 2015, and commissioning took place during a scheduled plant shutdown at the turn of the year 2015/16 with industrial rolling restored on January 2.
