Utilização de técnicas da manutenção centrada na confiabilidade aplicada no setor da fundição de uma indústria metalúrgica de grande porte do sudeste de Minas Gerais

Abstract

Many changes have been occurring over the last few decades with regard to industrial maintenance. Thus, the engineer stands out for being responsible for implementing analytical tools that provide safe decision making to achieve improvements in equipment maintenance processes. With increasingly aggressive competitiveness, extremely high levels of availability and reliability are required in order to achieve the goals. In contrast, traditional tools are unlikely to bring significant results, requiring the involvement of all layers of a company so that the changes reach the executors. In this context, the objective of the study was to apply techniques of centered maintenance and reliability in the sector and foundry of a large metallurgical industry in the southeast of Minas Gerais, in order to achieve improvements in the availability and reliability of equipment. Initially, a bibliographic research was carried out on the subject in question, and later the Reliability Centered Maintenance methodology was applied, in order to provide greater competitiveness and productivity for the company. Based on the objective of this work, it is concluded that this was successfully achieved. So, it was possible to provide the application of a worldwide known methodology in an extremely critical sector of metallurgy, providing better working conditions and a new, broader view on maintenance planning. Finally, the study promoted greater equipment performance, in order to provide greater reliability, in which they were designed, providing cost reduction with corrective maintenance.
