Análise de confiabilidade de um sistema de transporte de placas de aço do laminador de tiras a quente

Abstract

The work presents the modeling of the system of transport of the steel plates denominated table of setting of the furnaces in a of Hot Strips. Seeking to obtain quantitative data of reliability and analysis of improvements and modifications in the components with the objective of increasing the reliability and availability of the system. The choice of the milling table for the development of the work for the potential impact on the productivity of the mill, and also the same, has a number of equal components working in series. It allows the modeling of the whole laminar cooling system through a concentrated analysis of the subsystems, called the drive unit. For the development of the work will be used to the reliability engineering methodology, specific software tools to treat historical data of subsystem failures and analyze problems in this system. After the quantitative reliability analysis, improvements will be proposed with a focus on the reduction and / or elimination of the main identified failure modes, seeking optimization of the resources and costs involved in maintaining the system.
