Cold Rolling - Reducing Losses on Annealing LineCosts & Benefits
|Parent Process: Rolling Mills|
|Energy Savings Potential||
Implementing loss reduction measures for a continuous annealing line, energy use can be reduced by up to 40-60% compared to furnaces without heat recovery (Worrell et al., 2010. p. 105).
Energy savings can amount to 0.3 GJ/t-product for fuel and 0.011 GJ/t-product for electricity (US EPA, 2010. p. 29).
|CO2 Emission Reduction Potential||
Emission reductions are estimated to be 17.5 kg CO2/t-product.
Investment costs in a plant in Netherlands were estimated to be $4.2/t-product. The payback time is estimated as 4 years (US EPA, 2010. p. 29).
Cold Rolling - Reducing Losses on Annealing Line Publications
The U.S. Environmental Protection Agency’s (EPA) energy guide, Energy Efficiency Improvement and Cost Saving Opportunities for the U.S. Iron and Steel Industry, discusses energy efficiency practices and technologies that can be implemented in iron and steel manufacturing plants. This guide provides current real world examples of iron and steel plants saving energy and reducing cost and carbon dioxide emissions.
