What Is Pig Iron & Cast Iron? | Our Pastimes
Pig iron and cast iron are different types of metal. Pig iron is an unrefined product that has been converted from iron ore, one step in the process to create steel. Cast iron is then derived from pig iron that has been remelted, along with scrap iron and scrap steel.
Metal Casting Methods: Life of a Casting | Reliance Foundry
Metal casting is the process of pouring molten metal into a shaped space so that it will cool and harden in that form. For many items, this process can be less expensive than machining the part out of a piece of solid metal. Even though the idea behind it seems

Iron and Steel Emissions | Global Greenhouse Warming
Iron is the most abundant element by mass of our entire planet, making up 35% of the mass of the Earth as a whole. Steel is an alloy consisting mostly of iron, with a carbon content between 0.02% and 1.7 or 2.04% by weight (C:1000–10,8.67Fe), depending on grade.
Study and Observation of Process Parameters for Spheroidal Graphite (SG) Iron …
of cast iron by minimizing undercooling and increasing the nuer of nucleation sites during solidifiion. Inoculation changes the structure of cast iron by altering the solidifiion process. The first metal to solidify in hypoeutectic grey iron is primary
Cast iron pipe - Wikipedia
In cast iron pipe, the graphite forms flakes during the casting process, when examined under a microscope. Cast iron pipe was superseded by ductile iron pipe , which is a direct development, with most existing manufacturing plants transitioning to the new material during the 1970s and 1980s.
What is Ductile Iron? - Willman Industries
Ductile Iron is a type of cast iron known for its impact and fatigue resistance, elongation, and wear resistance due to the spherical (round) graphite structures in the metal. Ductile Iron is also called ductile cast iron, spheroidal graphite cast iron, or nodular cast iron.

How is Wrought Iron Made? - History of Steel - Carolina …
The process of making the various kinds of iron and steel is described below. The difference between iron and steel is based on the amount of carbon contained in the metal. If less than 0.1% carbon is present in the metal, it is termed wrought iron, and it remains a ductile metal that can be heated and welded, but not hardened; it can be softened but not made fluid by an ordinary furnace, even
The Metal Casting Process Explained | General Kinematics
Later, around 2000 BCE, iron was discovered. But it was not until around 700 BCE that the first production of cast iron was developed in China. Interestingly enough, the sand molding process of casting metals was also invented in China in 645 BCE.
