Pig iron - Wikipedia

Modern steel mills and direct-reduction iron plants transfer the molten iron to a ladle for immediate use in the steel making furnaces or cast it into pigs on a pig-casting machine for reuse or resale. Modern pig casting machines produce stick pigs, which break into smaller 4–10 kg piglets at discharge. References

Production of Materials – Metals

Mar 03, 2016  Cast iron; This is produced by refining pig iron in a furnace called cupola it contains 2% to 5% of carbon. The pig iron scraps and some limestone are put in the furnace and burnt together with coke fire. The molten pig iron is then put into moulds to form either white cast iron (in form of iron carbide) or grey cast iron (in form of graphite).
