Metalurgické zpracování jakostních litin s kuličkovým grafitem

Abstract

This thesis addresses the technological process of production of ferritic spheroidal graphite cast iron designed for ingot weighing between 2-5 tons. In the theoretical part are described the different effects of chemical elements, vaccination and modification of the resulting structure of spheroidal graphite cast iron. In the experimental part of the thesis focuses on the evaluation of the mechanical properties of cast-tests, the microstructure obtained cast-testing and comparing values according to EN ČSN 1563.
