Análisis y mejora del sistema de desengrase de chapas metálicas para reducir el índice de cráteres al final del proceso ELPO de la planta de pintura de CIAUTO

Abstract

The present research of curricular integration titled “ANÁLISIS Y MEJORA DEL SISTEMA DE DESENGRASE DE CHAPAS METÁLICAS Y REDUCIR EL ÍNDICE DE CRÁTERES AL FINAL DEL PROCESO ELPO DE LA PLANTA DE PINTURA DE CIAUTO”, had the objetive of improving the metal plate degreasing system, to avoid defects in the units. For that purpose, the amount of oil in the thanks and the current operation of the degreasing system were evaluated. After identifying the parameters that did not allow a correct oil separation, some parameters were modified, such as: capture (constant flow input), separation (longer residence time of the solution in the equipment, solution temperature), and a new degreasing system was implemented only for tank N°1, leaving the previous degreasing system for thank N°2 After these changes were made, it was possible to obtain two efficient degreasing systems, both in production and non-production days; tank N°1, which has a tray collection method, keeps working 24 hours a day without the intervention of an operator; on the other hand, tank N°2 changed from an efficiency of 27% to 72% in a production day, and in a non-production day it moved from 59% to 86% efficiency, in addition, the useful life of the solutions in the two tanks increases since they do not mix with each other because they maintain independent systems. It is recommended to change the catchment system of tank N°2 to batter trays to prevent an operator be aware of the level of the tank.
