Steel industries are among the most energy-intensive sectors, and reducing energy intensity without compromising productivity requires a combination of technological, operational, and managerial strategies focused on process optimization. One primary approach involves improving the efficiency of core processes such as ironmaking, steelmaking, and rolling operations. In the blast furnace process, for example, optimizing the burden composition, preheating of air, and control of temperature profiles can significantly reduce fuel consumption while maintaining production rates. Similarly, in electric arc furnaces, precise control of electrode positioning, arc length, and power input minimizes energy wastage and enhances melting efficiency. Another
