The Use of Foundry Pig Iron in Grey Iron Castings
- Foundry Pig Iron is suitable for iron castings used in general engineering, machine tools and parts for automotive industry. Due to the high proportion of iron ore used in the production of Foundry Pig Ironthe formation of pearlite in the finished casting is promoted. This effect is enhanced when more than 10% of Pig Iron per charge is used.
- The use of Foundry Pig Iron promotes graphite formation, reduces primary chill and improves machinability. This is particularly important in thin-walled castings.
- The use of costly chill reducing inoculants can be minimised through increased additions Foundry Pig Iron.
- The content of detrimental trace elements such as Cr, V, Pb and Ti in Foundry Pig Iron is kept to a minimum by the controlled selection of iron ore and other charge materials.
- The high density of Foundry Pig Iron will improve melting rates or reduce energy consumption. Steel scrap requires more energy to melt due to its lower carbon content compared to Foundry Pig Iron. In an electric induction furnace savings could be as high as 50 KWh/tonne of molten metal. In a cupola furnace savings of up to 50 kg coke per tonne of molten may be achieved.
