Tenova Core will provide a major revamp of the existing Consteel® system at Gerdau Ameristeel’s Charlotte, N.C., plant. The project scope includes newly designed preheat pans and preheat hoods to reduce the refractory maintenance of the conveying system. The current Consteel water seal system will be replaced with a dry seal system. Tenova Core will also revamp the connecting car that joins the EAF to the Consteel conveyor.
Consteel is a continuous steelmaking process that preheats and feeds scrap and other raw materials directly into the EAF via a patented conveying system through the EAF sidewall. The system in Charlotte was supplied in 1989 and represents the first commercial installation of the technology.
