Planejamento e controle da manutenção aplicados em uma indústria siderurgica

Abstract

The importance of maintenance in the current scenario can be observed through the high investments that companies started to make since the conception of the design, excellence in execution, attribute of quality and studies of Maintenance Engineering in order to ensure increased availability of machines and equipment and avoid unscheduled interruptions that impact on lost productivity. For these goals to be achieved companies need to consider two elementary conditions for existence of maintenance programming, planning and control: demand and service capacity. It is also necessary for companies to know the demands of the areas, through maintenance plans and database updated regarding the interventions that were made, so that the Planners can measure activity durations. In this sense, the objective of this work is to analyze the contribution of the adequacy of the system of Maintenance Planning and Control with a focus on cost reduction maintenance in a steel industry. The results show the importance of PCM (Maintenance Planning and Control) and the change in the hierarchical structure of the company's maintenance, which generated a contraction significant in costs, being possible to visualize in the first two years a around 30% reduction in maintenance bills.
