CI Casting uses may be observed in industries that produce water, gas, sewage, sanitary fittings, and manhole coverings, among other things. Wheels for carriages and rail chains can both be made of cast iron. To create crude ingots known as pigs, the liquid iron is cast, poured, and then solidified. CI Casting is created by the reduction of iron ore in a blast furnace. It is used to build engine blocks, cylinder heads, gear blanks, and housings because it can withstand wear.
