Rediseño y construcción de la máquina de colado centrífugo horizontal

Abstract

This document covers the redesign and the construction process of a horizontal centrifugal casting machine owned by the Casting Lab from the Mechanical Engineering College part of the National Polytechnic School in Ecuador. The device´s current state was determined by identifying the reasons and factors that have caused current deficiencies that do not allow its use and to fulfill the purpose for which it was built. As a result, a mechanical redesign of the machinery was performed, setting possible alternatives to fix the deteriorated systems. With the help of a weighted criteria matrix, the best alternative was chosen, followed by its implementation through detailed design, calculation, and construction. The final redesign included a new transmission system and added a superior mold support suspension mechanism. Finally, the pipes quality was evaluated using non-destructive tests (NDT), visual inspection, and dye penetrant testing.
