Carburiser properties transfer into the structure of melted cast iron

Heredity in the microstructure of cast iron produced solely from scrap (synthetic cast iron) was considered experimentally. The carbon deficiencies were adjusted using anthracite, synthetic graphite and petroleum coke as carburisers. The small flakes of anthracite resulted in smaller graphite flakes in the final microstructure, proving that heredity is affected by the carburiser as much as by the particular “pig iron-steel scrap-cast iron” combination.
