In a general sense, "arrabio" refers to pig iron, which is the intermediate product of smelting iron ore with a high-carbon fuel such as coke, usually in a blast furnace. This crude form of iron contains high levels of carbon along with various impurities like silicon, manganese, and sulfur, making it brittle and unsuitable for direct use in most applications. Pig iron is an essential raw material in the steelmaking process, where it is further refined to reduce impurities and adjust its composition to produce various grades of steel and cast iron.
