O uso de ferramentas de manutenção para o aumento da confiabilidade de agitadores na área da precipitação da ALUMAR

Abstract

This paper studies the case ofone of the biggest aluminium companies in the world, highly competitive in the market and that is always incentivising employees to propose suggestions for improvements in the fields of technology, processes and maintenance. Searching to optimize maintenances of a specific group of equipment, the precipitators, the main goal of this research is to use tools from maintenance and reliability engineering like the Modus Analysis and the Effect of Failure, calculus of MTBF, MTTR and availability, to accompany and find out what is the most common kind of failure in the group of actives, which actives have suffered from this most common failureand from the collected data develop fast improvements with the area maintenance crew and relate in a statistic and punctual manner to the reliability engineering team of the company, the element to be worked with, focusing on the equipment failure reduction, enhancement of production and, consequently, the profit
