limestone in pig iron process

Liquid iron collects at the bottom of the blast furnace, underneath a layer of slag. The blacksmith periodically lets the liquid iron flow out and cool. At this point, the liquid iron typically flows through a channel and into a bed of sand. Once it cools, this metal is known as pig iron…

    Generation of iron and steel slag NIPPON SLAG ASSOCIATION

    While limestone may seem unrelated to the production of iron and steel, it actually is an essential auxiliary material that is added during the production process. During the process ofreducing iron ore, it isnecessary to remove the silica,alumina (Al 2 O 3), and othernon-ferrous components contained in iron ore. The added limestone fuses with these components and lowers their melting point, making it …

    What is Forging Iron (with pictures)

    Pig iron is a basic form of forging iron. This is one of the first processed forms of iron after it is removed from iron ore. The raw iron is mixed with coke and limestone toproduce a white,chalky and irregular form of iron. Coke is used to produce pig iron. Originally, the iron was cast into a mold made of sand.
