Iron ore is reduced and manufactured into steel in a modern plant where, in a continuous process, ore is crushed and mixed with coke and then fed into the top of a blast furnace. Molten iron flows off from the bottom; slag is skimmed off; and iron is converted to steel by blowing oxygen through it to remove residual carbon, adding lime and magnesium powder to remove other trace solid impurities. Alloying metals are then added to the steel. The molten metal is cast into molds which are later rolled into required shapes
