EAF Raw Materials & DRI, Use of DRI in Steelmaking
Nucor Hickman charges up to 60% DRI. The levels of DRI vary according to business conditions which means Hickman must be able to rapidly adjust to changes. High DRI rates means generation of high levels of carbon monoxide, which must be controlled for safety and efficiency reasons.
Levels of carbon in the DRI, carbon and oxygen injection and DRI/scrap mix can change heat to heat, causing issues with overheating, steel chemistry and emissions. AMIGE has developed an improved process control system which utilizes the ZoloSCAN laser technology to measure furnace offgas and temperature.
Improved control of the melting and chemical energy practice, along with overcoming the unique challenges of a DC furnace are discussed, through the implementation of AMIGE SmartFurnace and ZoloSCAN
