Análisis cuantitativo de los elementos aleantes principales precipitados en la formación de billets de aluminio de aleación 6063 en equipo de fundición tipo hertwich de colada continua horizontal que se producen en la empresa Cedal S.A de la ciudad de Latacunga para el proceso de extrusión

Abstract

Lack of “in-situ” studies about horizontal continuous casting process applied in production of aluminum alloy 6063 cast billets, promotes to investigate the direct influence of: temperature, velocity and raw material. Applying spectrometric tests to quantify the weight percent of main alloying elements such as Magnesium and Silicon. These elements precipitate to form magnesium silicide (Mg2Si) during homogenization process. For this study it was necessary to produce billets with normal and experimental alloy levels to demonstrate an inverse relation between magnesium silicide and Brinell hardness. Equally important, the effect of reduction of the material tensile strength due to low levels of magnesium silicide.
