摘要

Regular grade petroleum coke is often used as carburizer in the foundries. Selection of carburizer depends on several factors, the most important being microstructure, physical-chemical properties and price. The paper investigates microstructure and physical-chemical properties of commercial coke as a potential carburizer in iron-carbon alloys. The content of carbon, sulphur, ash, some metals (Ni, Fe, V, Na), moisture, volatile matter and density was determined. Microstructure was determined by optical microscopy method. The results indicate that the analyzed coke and cokes of similar properties can be used as carburizers in the foundries.
