How changes in scrap mix affect Consteel charging of an EAF
Consteel charging The Consteel furnace is by its nature both dif-ferent and similar to a conventional EAF. The Consteel process is continuous so scrap densi-ty does not affect the number of charges as the scrap is continuously fed into the EAF through the side of the furnace. A good Consteel oper-ations is achieved matching energy input to
