Iron foundries require metal of controlled composition and temperature, supplied at a rate sufficient to match the varying demands of the moulding line. The metallic charge to be melted consists usually of foundry returns, iron scrap, steel scrap and pig iron with alloying additions such as ferrosilicon. The majority of repetition iron castings are made in green sand moulds with resin-bonded cores. The great merits of grey iron are its low cost, its high fluidity at modest temperatures and the fact that it freezes with little volume change. Ductile iron has high ductility allowing castings to be used in critical applications.
Foseco offers a wide range of foundry consumables and equipment to meet the requirements of the different types of cast iron.
