Diseño y construcción de un contenedor con atmósfera controlada para la fabricación de espuma de aluminio para el laboratorio de materiales de la Carrera de Ingeniería Mecánica de la Facultad de Ingeniería Civil y Mecánica de la Universidad Técnica de Ambato

Abstract

In the area of Materials Engineering at the Technical University of Ambato there is no controlled atmosphere machine for materials research. Therefore, in the development of the project, the construction of the machine for the manufacture of aluminum foam used in the automotive and aeronautical process has been proposed due to its favorable mechanical properties for the reduction of weights, in the development of the project it was determined that Three systems intervene in the manufacture, the generation of vacuum inside the container with which a controlled atmosphere is achieved, later it enters the oven at a temperature of 740-800 degrees Celsius for a time of 1.5 to 2 hours, at the end of the indicated time is removed from the oven and concluded with the application of the inert gas system (Argon) during cooling, the inert gas allows us to accelerate the cooling of the sample and create a protection for the element. The project concludes with the manufacture of a container, purchase of equipment, assembly and tests, in the manufacture of the mold the design parameters have been defined in casting the aluminum, in a stainless steel container, with an easy-to-remove lid. and hermetic closure, tests were carried out in an oven at 740-800 degrees centigrade with a needle valve with quick coupling that allowed us to seal, open and close the container.
