Estudos das métricas de confiabilidade e do custo do ciclo de vida do sistema de oscilação de uma máquina de lingotamento contínuo de placas

Abstract

The objective of this report is to perform the Life Data Analysis (LDA) of the mold oscillator equipment of the Continuous Casting Machine of Slabs (CCM), as well as the equipment life cycle cost (LCC) comparing with different technology, that it will be evaluated the possibility of changing the complete oscillation system of this machine by another model with better maintainability them actual mold oscillator. Every study will consider the life of the equipment from the beginning of operations, mainly considering the oscillating table and oscillating cylinder. The life of similar equipment in the world will also be evaluated, increasing the number of surveys and life data already realized to make more representative the number of information’s for analysis. For current and future costs will be considered the costs practiced since the beginning of operation of the equipment and the average margins of profit of the business and these will be drivers to definition of maintenance actions adopted from 2019 onwards.
