How Iron and Steel Work. Another way to create steel from pig iron is the Bessemer process, which involves the oxidation of the impurities in the pig iron by blowing air through the molten iron in a Bessemer converter. The heat of oxidation raises the temperature and keeps the iron molten. As the air passes through the molten pig iron,

Siemens Martin Open Hearth Process. As soon as all the steel has melted, slag forming agents such as limestone are added. The oxygen in iron oxide and other impurities decarburize the pig iron by burning the carbon away, forming steel. To increase the oxygen contents of the heat, more iron ore can be added.

How Iron and Steel Work. Once it cools, this metal is known as pig iron. To create a ton of pig iron, you start with 2 tons (1.8 metric tons) of ore, 1 ton of coke (0.9 metric tons) and a half ton (0.45 metric tons) of limestone. The fire consumes 5 tons (4.5 metric tons) of air. The temperature at the core of the blast furnace reaches nearly 3,000

Jun 21, 2016Steel making is the method of processing and producing steel from iron ore and scrap. It focuses on removing the slugs and other unwanted materials like phosphorus, sulphur, silicon, nitrogen, and excess carbon from the raw iron. The next step targets on alloying it by adding various elements like manganese, chromium, nickel, and vanadium.
