A Case Study of the Effectiveness of Rolling Process to Manufacture the Strip of Leaf Spring

P. S. Chauhan and C. M. Agrawal
Abstract—Hot rolling is the key process that convert cast or semi finished steel into finished products. Since the rolling operation is very costly, hence quality control of rolling process is essential. The raw material of leaf spring i.e. strip of SUP 11 is manufactured with hot rolling process. Any defect in the material may result rejection of final product that leads to major loss in terms of money and sometimes major accidents also. In this paper, the concept or voice of customer of India has been developed and shown the internal customer relationship among the various flow processes to achieve the full satisfaction of internal customer that leads to the satisfaction of external customer. Internal customer’s job is to look after proper functioning of the process and minimization of the defects in the final process which leads to minimization of defects in the final product. Different defects have been taken into consideration by using Juran seven quality tools & New Seven quality tools, like Brain Storming, Cause and Effect diagram, Pareto analysis, problem solving session etc. to diagnose the root cause of the defect and accordingly corrective measures have been suggested.

Index Terms—Hot rolling, internal and external customer, juran quality tools, leaf spring, SUP 11.
