Item MAPEAMENTO E ANÁLISE DE FALHAS NA MANUTENÇÃO DE CALDEIRAS: estudo no setor metalúrgico(Universidade Federal do Maranhão, 2014-10-03) Carvalho, Mônica Jacyra da Silva; SOUZA, Leonardo Leocádio Coelho de; CPF:11100101000; http://lattes.cnpq.br/5699049219268606The metallurgical Alfa has three areas of operations: the Port, the Refinery and the Smelter. The intermediate area produces alumina using steam as an energy source. This comes from two High Pressure Boilers that operate together and are essential for the full operation of the process, so it is necessary make it reliable equipment. With this in mind, Alfa industry bases its operations management in a Own Business System adapted guidelines of the Toyota Production System (TPS) and Total Productive Maintenance (TPM). So, this was seen as an opportunity for research, which was carried through the search for understanding of the Business System, the definition and understanding of the equipment, the realization of hiking equipment by a multidisciplinary team, with a survey of existing equipment failures, by mapping the current situation, identifying the losses associated with the faults previously raised by raising costs and monitoring focused on technical resolution and human reliability during maintenance activities, which were carried out to remedy or minimize failures, as described. Thusthere was a reduction in production losses around 3484.28 t SGA/year and 304.526,07 US$/year of 2011compared to the year 2012. And also proof that the boiler reaches 100% of their operational availability and yes, they can become confident with the implementation of continuous improvement.
