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.
Proper Reheating Temperature
Provided that intermediate and final product characteristics allow, the heating temperature of the reheating furnace can be reduced. However, lowering the heating temperature will increase the rolling forces and moments, which in turn will result in increased energy consumption – due to increased mechanical and electrical loads – and will increase wearing off of the equipment. Consequently, in finding the optimum temperature level in the reheating furnace a wider set of factors need to be considered within a systems approach (Worrell et al., 2010. p. 93).

Energy Savings Potential |
A reduction of the heating temperature 100°C in the reheating furnace decreases unit fuel consumption by 9% to 10%. However under certain conditions total energy consumption may not decrease with a decrease in heating temperature. |
