Consteel installations are characterised by a relatively low installed active power factor which increases with heat size
(Fig 2). The correlation factor between the two parameters is very high. The data reported in Fig 2 is relevant to the existing installations and show the Active Power used in a Consteel being on average 0.53 times the heat size of liquid steel. That is a remarkable correlation, considering the significant difference between the various installations
in terms of steel grade (from rebar to stainless steel) and scrap mixes. This is perhaps the most important design difference between a Consteel and a conventional EAF. In Ultra High Power electric arc furnaces bucket charged the relationship between active power and heat size can be as high 1:1. In contrast, Consteel reduces the ratio to 0.5:1.
