Quality of carburizers and its influence on carburization process
Journal Title: Archiwum Odlewnictwa - Year 2009, Vol 9, Issue 3
Abstract
In the papers issue of production the synthetic cast iron obtaining on the basis of only steel scrap and carburizing materials are presented. Natural graphite, synthetic graphite, anthracite, petroleum coke, foundry coke and charcoal were used to carburization. Examinations covered evaluation of used carburizers taking into account chemical composition; carbon, sulphur and nitrogen content have been analyzed. Obtained effectiveness of carburization with method of inserting carburizing material into charge in solid, were especially taken into considerations. The comparison between mechanical properties (tensile strength and hardness) of produced synthetic cast iron and cast iron obtained on the basis of pig iron have been carried out.
