Raw Materials and the Manufacture of Steel The blast furnace turns the iron ore into pig iron, the chief ingredient used to make the steel. Inside the blast furnace, coke and iron ore are alternately poured in from above, while air heated to 1,000-1,200 degrees Celsius is blown in from below. The iron ore melts and reduces to give pig iron, which is then conveyed to the next process by …
