Optimising Consteel continuous scrap feeding with roof-fed DRI

For EAF furnaces charged jointly with scrap and with DRI through the roof, feeding the scrap via a Consteel pre-heater conveyor rather than by bucket enables a shorter power-on time, increases productivity and improves all other operating parameters, except carbon injection, resulting in a significant saving in electrical energy.
