Resumen
El trabajo de tesis se realizo con el objetivo de dar a conocer y a su vez
plantear soluciones que disminuyan los tiempos improductivos en el Proceso
de Laminación de la Empresa ANDEC. Específicamente involucrándonos
con el Agua Tipo – B, que es fundamental para la mantenibilidad y
durabilidad de los rodillos de laminación, justificando de esta manera la
implementación de nuestra propuesta de donde se tomo como problema
puntual el alto contenido de laminilla (hierro) el mismo que afecta, deteriora
y disminuye el tiempo de trabajo de los equipos del proceso. Para la
realización de nuestra propuesta implementamos técnicas tales como método
de muestreo (análisis químico del agua tipo – B), histogramas, diagrama
causa – efecto, grafico de pareto. Los resultados obtenidos en el grafico de
pareto de tiempo improductivos nos arrojaron un tiempo de 1718 minutos,
este tiempo es el que se dejo de producir alrededor de 1430 toneladas de
producto terminado el precio de venta por tonelada producida actualmente
es de $815, de donde la empresa a dejado de percibir no mas allá de
$1’165.450 debido a los diferentes tipos de problemas que se presentan en el
sistema de Agua Tipo – B. En el planteamiento de las soluciones que nos
lleven a mejorar la calidad del Agua Tipo – B. Mediante alternativas tales
como: Decantación del Agua, Ampliación del Sistema de Retorno e
Implementación de un Sistema de Filtración. El costo y calendario de la
inversión que se realizara para el montaje y puesta en marcha del sistema
para la optimización en la calidad del Agua Tipo – B se presentaran de
acuerdo a indicadores financieros tales como: Tasa de Interés de Retorno,
Costo/Beneficio, Tiempo de recuperación de la inversión. De acuerdo con el
calculo realizado la Tasa Interna de Retorno TIR nos arroja el 44.8%,
superando la tasa mínima de rentabilidad determinada por la empresa. El
tiempo de recuperación de la inversión se basara en todos los datos que se
obtuvieron en este capitulo para así poder conocer el periodo de
recuperación de la inversión para la implementación de la propuesta. Se
utilizara la tasa mínima de rentabilidad 12.5% de Acerias Nacionales del
Ecuador S. A. debido a que no se ha realizado ningún tipo de préstamo a
entidad financiera alguna. De acuerdo con los resultados obtenidos, el
periodo de recuperación de la inversión será en 12 meses.
The thesis work was carried out with the objective of publicizing and in turn propose solutions that reduce unproductive times in the Process of Lamination of the ANDEC Company. Specifically involving ourselves with Type - B Water, which is essential for maintainability and durability of the laminating rollers, thus justifying the implementation of our proposal from where it was taken as a problem punctual the high content of lamella (iron) the same that affects, deteriorates and reduces the working time of the process equipment. For the realization of our proposal we implement techniques such as method sampling (chemical analysis of water type - B), histograms, diagram cause - effect, pareto chart. The results obtained in the graph of Pareto of unproductive time gave us a time of 1718 minutes, this time is the one that stopped producing around 1430 tons of finished product the selling price per ton currently produced is $ 815, from where the company has stopped receiving no more than $ 1'165,450 due to the different types of problems that arise in the Water system Type - B. In the approach of the solutions that we lead to improving the quality of Type - B Water. Through alternatives such such as: Water Decantation, Expansion of the Return System and Implementation of a Filtration System. The cost and schedule of the investment to be made for the assembly and commissioning of the system for the optimization in the quality of Type - B Water will be presented as according to financial indicators such as: Return Interest Rate, Cost / Benefit, Investment payback time. According to Calculation made the Internal Rate of Return IRR gives us 44.8%, exceeding the minimum rate of return determined by the company. The payback time will be based on all the data that is obtained in this chapter in order to know the period of investment recovery for the implementation of the proposal. I know will use the minimum rate of return 12.5% of Acerias Nacionales del Ecuador S. A. due to the fact that no type of loan has been made to any financial institution. According to the results obtained, the The investment payback period will be in 12 months.
