Abstract: Steel Re-Rolling mill is the second most important steel forming industry in India. The manufacturing process of steel re-rolling from ingots to finished products has high energy consumption and it directly affects productivity and manufacturing cost. Measuring the productivity of the process can unleash the low productive process, which leads towards rectification for increasing the productivity of lean area. The productivity of Steel Re-Rolling mill is measured by Performance Objective – Productivity model. Key performance areas were identified by intensive survey and process of prioritization was carried out. The actual values of the Key performance Areas of the system were compared with the objectivated values of the system. The outcomes lead to Productivity Index of the system, sub-system and key performance areas of the process revealing the areas with low-performance index which have the highest impact on productivity of the process. The energy subsystem is having the lowest performance index and is the main source of loss and recommendations are made to increase the productivity of energy sub-system.
Keywords: Key Performance Areas, Performance objective productivity Model, Productivity, Productivity Index, Steel re-rolling mill.
