Abstract

O projeto de Prolongamento da Vida Útil (PVU), iniciado no ano de 2013, é uma estratégia adotada pela ArcelorMittal Monlevade, com o objetivo de estender a campanha do Alto-forno A através de criteriosas ações, com destaque para: Identificação de desgastes de equipamentos críticos para a operação, planejamento e execução da reparação destes, monitoramento e inspeções temporais em diferentes componentes, implantação de novos equipamentos e instrumentação, visando maior controle e robustez operacional, dentre outros. O início de operação do Alto-forno A ocorreu em 1999, com uma campanha inicial prevista para 15 anos. Atualmente, a sua reparação completa está prevista para 2027, quando totalizará 28 anos de operação. Dentre as principais justificativas para tal resultado destacam-se: Rigoroso controle de qualidade de matérias-primas, cultura de excelência operacional e controle de processo, adequada manutenção dos equipamentos e implantação do projeto PVU. A criação do PVU trouxe até então expressivos ganhos para a siderúrgica por: Postergar a reparação completa do Alto-forno A, aumentar o controle e monitoramento dos principais equipamentos, gerando maior segurança de pessoas e operacional, evitar paradas não-programadas, o que impacta positivamente na estabilidade operacional e consequentemente no custo de produção e qualidade do gusa, melhorando assim a eficiência, produtividade e competitividade da empresa

 

The Service Life Extension (SLE) project, started in 2013, is a strategy adopted by ArcelorMittal Monlevade, with the goal of extending the Blast Furnace A campaign through careful actions, with emphasis on: critical equipment for the operation, planning and execution of their repair, monitoring and temporary inspections in different components, implementation of new equipment and instrumentation, aiming greater control and operational robustness, among others. The start-up of Blast Furnace A took place in 1999, with a 15-years planned initial campaign. Currently, its complete repair is scheduled for 2027, when it will total 28 years of operation. Among the main justifications for this result are: Rigorous raw materials quality control, culture of operational excellence and process control, proper maintenance of equipment and implementation of the SLE project. The creation of the SLE has so far brought significant gains for the steelmaker by: Postponing the complete repair of Blast Furnace A, increasing control and monitoring of the main equipment, generating greater personnel and operational safety, avoiding unscheduled downtime, which impacts positively on operational stability and consequently on the hot metal cost of production and quality, thus improving the company's efficiency, productivity, and competitiveness.
