Paper Title: Application of Six Sigma Approach for Improving Steel Quality – A Case Study
Unique Id: IJSDR1606046
Published In: Volume 1 Issue 6, June-2016
Abstract: The application of six - sigma methodology to enhance steel quality in a steel manufacturing industry is demonstrated in this paper through a case study. Six sigma five phase methodology i.e., DMAIC is adopted in this study. The presence of non-conformance of phosphorous content to the specification is the most significant cause for obtaining Off Grade steel, which is identified through Pareto analysis in the definition phase. In the measure phase, the process capability indices are calculated using base line statistics. Cause and Effect diagram is prepared in the analysis phase to identify the potential factors which influence the Phosphorous content in steel. Design of experiments is employed in the improvement phase to identify the ways to improve the process so as to reduce the Off Grade steel. Finally, in the control phase, the improved system is monitored by using process capability analysis.
Keywords: Six sigma, Off Grade steel, Process capability indices, Cause and Effect diagrams, Pareto Diagram
