Application of Quality Tools for Process Improvement to Reduce Scrap in an Aluminum Smelter

Abstract

This paper presents a use of quality tools for the improvement of an aluminum smelting process under pressure by reducing the waste. This type of analysis has been useful in a developing country like Brazil, with the present example shown in such promising reality. The main tool used was the cause and effect diagram, enabling the discovery of the main causes of the problem, the removal of which led to a reduction in scrap that is of extreme relevance to the organization, as statistically proven. © IFIP International Federation for Information Processing 2014.
