contact usLime is used to convert iron into ''pig iron''. In the blast furnace, finely ground or granular limestone (with a low sulfur and alkali content) is used together with finely ground lime to convert ore into pig iron. The pig iron is later processed into steel. Lime is used as a fluxing agent in electric arc furnaces and basic oxygen furnaces ...
contact us· Carbon plays a very important role in influencing the brittleness and hardness balance in iron. To reduce the carbon content of pig iron, it is melted again with scraps of iron and coke and subjected to the blast of hot air. This kind of iron is known as Cast Iron and has a lower carbon content of about 2 – 3 %. This is even harder than pig iron.
