Energy Efficiency Drives for Rolling MillsCosts & Benefits

Parent Process: Rolling Mills
Energy Savings Potential

High efficiency motors can save approximately 1-2% of the electricity consumption. Assuming an electricity demand of 220 kWh/t-hot rolled steel, the electricity savings are estimated to be 4 kWh/t-product (Worrell et al., 2010. p.100).

CO2 Emission Reduction Potential

Emission reductions are estimated at 1.6 kg CO2/t-product. 

Costs

The additional cost of the high efficiency drives was estimated to be approximately $0.30/t-hot rolled steel. The payback time is estimated as 3.2 years (US EPA, 2010. p. 25).
