Actualización de la gestión del mantenimiento en secciones de crudo y horno en la planta CEMEX Colorado de Abangares.

Abstract

Now a days, large companies or even SMEs have tried to improve their processes and increase their profits through a good maintenance management, since many years maintenance has been stopped seeing as a department responsible for dealing with faults, to be entities responsible for ensuring that the objectives of the companies are met, through good management and good use of assets. Being aware of this, CEMEX one of the leaders worldwide in the production and distribution of highquality cement, aggregates and concrete, has invested large sums of money for the improvement of their maintenance activities through the implementation of world class maintenance practices. However, it is not a secret that a maintenance program should be dynamic, i.e kept constantly updated and improved continuously, this is perhaps one of the aspects that many companies have forgotten; CEMEX seeks to eliminate these malpractices. To achieve this, first was important to evaluate the current maintenance management to find possible improvement points. As a second step, was established the hierarchy of assets considered critical for the company, in order to have fundamentals in making decisions and establishing maintenance policies, allowing to assess, if there is justification for repair an asset or just let it fail. Finally, equipment were analyzed according to hierarchy of assets considered critical; were evaluated if current maintenance activities are cost efficient; identifying this, was possible to obtain a 15% reduction in the costs of preventive maintenance in these equipments, which, as a consequence, increases productivity and profits, allowing to produce more, with less resources.
