DEMONSTRAR AS FORMAS DE EVITAR REFUGO EM PEÇAS DE FERRO FUNDIDO CINZENTO CONSIDERANDO A PORCENTAGEM DE CARBONO, SÍLICO E COBRE NA LIGA FUNDIDA

Abstract

This work addresses the main characteristics of gray cast iron in which there is an intimate correlation between the properties of cast iron and its structure, which, in the particular case of gray cast iron, is narrower and more complex, in view of the presence of free carbon in the form of graphite and its shape, distribution and dimensions that the graphite veins present and more the influence that it exerts for the appearance of defects such as depressions, fillings and cracks that in this sense, the thickness of the piece exerts. In this way, this work aims to present solutions and propose. changes in the casting process of gray cast iron in order to reduce waste generated by the influence of the chemical elements carbon, silicon and copper in the formation of casting defects.
