Rolling Mills | Industrial Efficiency Technology & Measures

Energy Efficiency Drives for Rolling Mills: 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). Emission reductions are estimated at 1.6 kg CO 2 /t-product.
