Deployment project for large-scale production line: Case study to project a Pickling line Vitor Caio de Almeida, Marcos Tadeu Tavares Pacheco, João Inácio Silva Filho

Abstract

In this work we present the methodology that addresses the implementation of a continuous Pick-ling line of hydrochloric acid in a steel mill. The process known as Pickling is one of the steps in the steel industry which consists of chemical action that aims at removing oxidation that appears on the surface of the metal strip in cold rolling. The pickling process is necessary to improve the surface quality of the metal strip with the removal of the thin layer of oxide. The production line studied in this work uses in removing the oxide layer using hydrochloric acid as a chemical compound. In the steel mill in question this line deploy-ment aimed to upgrade its technological equipment and products, to obtain greater competitiveness in the marketing of metallic carbon steel coils. The emergence of a new process line of this size is very rare be-cause of the high cost of deployment and high level of complexity and, in this article are the main stages and methodology in the implementation of this project using the action Master plan and the OEE (Overall Equipment Efficiency) as an indicator for measuring the progress and the quality of implementation and ap-plied in several steps such as; project specification, definition of the supplier, assembling, testing and oper-ating warranty.
