Ductile Iron | Metal Casting Resources

While ductile iron can be produced from steel or iron scrap, pig iron is the primary source of infeed for most modern ductile iron foundries. Pig iron refers to the primary iron production of a blast furnace that contains over ninety percent iron. The term “pig iron” arose from the old-fashioned method of casting blast furnace iron into molds arranged in sand beds in such a manner that ...
