Resumen
El presente trabajo se desarrolló en la Empresa Planta Mecánica en Santa Clara donde se realizó una evaluación de la efectividad de los Métodos de determinación de la geometría de las mazarotas para acero 1045.
En este trabajo, a partir de la revisión bibliográfica, se seleccionó una pieza tipo rueda a la que se le realizó la tecnología de fundición, detallando el análisis sobre cada uno de sus aspectos y concretamente el cálculo de la geometría de las mazarotas por los dos métodos propuestos, resultando que por el método de los módulos se obtiene un mayor rendimiento tecnológico. Se aplicó la metodología del análisis de ciclo de vida y se determinó que los mayores impactos son debido al consumo de combustibles fósiles y la ecotoxisidad, con un 34% y 24% respectivamente según el Ecoindicacdor99.
This work was conducted in the company Mechanical Plant in Santa Clara where an assessment of the effectiveness of methods for determining the geometry of the steel riser for 1045 was performed. In this thesis, based on the literature review, a wheel type piece that was performed the casting technology was selected. A detailed analysis of each of its aspects, especially the calculation of the geometry of the riser by two proposed methods, from which it was conclude that the method of modules represents a better technological performance. The methodology of life-cycle assessment was applied and it was determined that the greatest impacts are due to consumption of fossil fuels and ecotoxisidad, with 34% and 24% respectively according to the Ecoindicacdor99.
