Track: Graduate Student Paper Competition

Abstract

With growing competition for markets in the various production sectors, both in Brazil are looking for improvements in the world, as well as improvements that can improve their productivity and  reduce production costs and quality services. For this, among other strategic actions, continuous improvement can be sought as a means to remain competitive. In this context, the present work case, developed as a work study, has as its central objective the reduction of refuges generated by deficiencies in the production process in a metallurgical company that manufactures ductile iron pipes, among other products. From the application of the method and quality tools used, it was possible to identify the main causes of scrap, favoring its reduction through process improvements. With the identification and analysis of problems related to the training of manpower, lack of compliance with material specifications, inadequate or unfulfilled methods of production and making adjustments to machines used in production processes, it was possible to reduce the occurrence of defects in cast iron pipes, when compared to the amount of scrap counted before and after the changes implemented. The results achieved showed significant gains for the company by reducing the amount of scrap and rework generated during the production process. The reduction in the occurrence of defects favored a reduction of costs, contributing for the company to become more competitive.
