Introducing various production costs for cast iron, sand casting by Dandong Foundry, including pig iron costs, steel scrap, alloy, nodulizer, resin sand, electric charges, machining, painting etc.
The name "pig iron" comes from the traditional method of casting the iron into molds arranged in sand beds in such a manner that they resemble a litter of piglets being suckled by a sow. This method is largely historical, but the term has persisted. Pig iron is primarily used as a raw material for further refining in steelmaking processes.
pig iron prices in China. Pig iron prices are very important to iron casting prices since pig iron is the main material for gray iron and ductile iron castings. For most of iron foundries, the cast iron prices should be adjusted according to the change of pig iron costs. Therefore, how do we know the current pig iron prices?
In addition, foundry iron is best produced in small blast furnaces, which are unsuited for steel manufacture, where the economy of scale is essential. During the early part of the twentieth century, for example, foundry iron consumers preferred pig iron that had been cast in sand. ... foundry iron consumers preferred pig iron that had been cast ...
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 …
Cast Iron. Cast iron is made from re-melting pig iron, usually with some quantities of scrap iron, scrap steel and some alloys, such as Cr, Ni, Mo and Cu according to the different requirements. Depending on the specific application, iron foundries reduce the carbon and silicon content to the desired levels from 2 to 3.5% and 1 to 3% respectively.
