Aplicação da metodologia de Taguchi para analise de desempenho de um virador de vagões- Vale/SA

Abstract

Application of quality methodologies in large projects should be increasingly present in the equipment in operation, as they help to understand some specific points that only during assembly are not informed. Taguchi's methodology is one of them. The same will be used to analyze the operation of a large equipment that is the Wagon Turner. And as with all equipment, there are points that can be improved, either costbenefit, efficiency or other point. During the process of ore discharge, a part of it is retained in the head of the fixing clips of the Turner forming a column of material, and this is the chosen point to apply the methodology of Taguchi, that requires a variation of some parameters of the Equipment such as: clamp shape, turning angle and along with the type of wagon, to reach the point of least loss and / or greater efficiency. In this study it will be possible to quantify such loss through volume and area calculations so that concrete values can be shown on theoretical grounds. In addition, this analysis can serve as a starting point for future improvement processes so that the loss of material in the Wagon Turner discharge is lower
