PRODUCTION OF NODULAR CAST IRON

U radu su navedene opće karakteristike nodularnog lijeva, kemijski sastav, svojstva te su navedene vrste nodularnih ljevova. Navedeni su postupci proizvodnje nodularnog lijeva te načini što bolje iskorištenja kemijskih elemenata potrebnih za proizvodnju i toplinsku obradu nodularnog lijeva. Prikazan je primjer proizvodnje nodularnog lijeva u ljevaonici i to priprema materijala, priprema slitine te obrada slitine.The paper describes the general characteristics of nodular cast iron, chemical composition, properties, and the mentioned types of nodular cast iron. The processes of nodular casting have been mentioned, as well as the methods of utilizing the chemical elements required for production and thermal nodular casting. An example of the production of nodular cast iron in the foundry is presented, including the preparation of materials, melt preparation and melt processing
