what is cast iron made of? Cast iron is made from pig iron, which is the product of melting iron ore in a blast furnace. Cast iron can be made directly from the molten pig iron or by re-melting pig iron, often along with substantial quantities of iron, steel, limestone, and carbon (coke), and taking various steps to remove undesirable contaminants.
Ironmaking blast furnace is vertical smelting furnace for continuous smelting of pig iron with iron ore as raw material, also called iron-smelting furnace or blast furnace.

The oxidized slag containing 12 to 16% of Fe is poured into a cast iron slag pot after the tapping and is disposed of in a slag yard.
cast iron flow chart. The pig iron flow chart provides a wide range of prices and price volatility. Among its various types, cast iron offers a variety of connections, each of which can exist and be effective in different sectors of the industry depending on the connections and capabilities they have. white cast iron
Pig iron is the product of smelting iron ore (also ilmenite) with a high-carbon fuel and reductant such as coke, usually with limestone as a flux. Charcoal and anthracite are also used as fuel and reductant. ... The term "pig iron" dates back to the time when hot metal was cast into ingots before being charged to the steel plant.
The article explains the importance of understanding a steelmaking flow chart, which outlines each step from raw material preparation to final products, aiding in efficiency and productivity. It details key components like raw materials iron ore, limestone, coal, primary steps raw material prep, ironmaking, steelmaking, and methods such as …
Cast iron is derived from pig iron, and while it usually refers to gray iron, it also identifies a large group of ferrous alloys which solidify with a eutectic. The colour of a fractured surface can be used to identify an alloy. White cast iron is named after its white surface when fractured, due to its carbide impurities which allow cracks to pass straight through.
