Pig Iron Production – Interstahl

Iron Ore and Coke Form Pig Iron in the Blast Furnace. To create pig iron in the blast furnace we need iron ore and coke. Iron ore may contain contaminants that must be removed by adding flux. The mixture of iron ore, flux and sometimes scrap metal is called a burden. A typical blast furnace is a cylindrical shaft furnace with a refractory lining on the inside. Hot air is blown through water ...

The molten iron is then run into moulds where it sets to a form known as pig iron. This iron can also be used in steel production or purified further to give wrought iron. Waste gas mixture that exudes from the furnace contains majorly nitrogen, 30% carbon(II)oxide and about 10% carbon(IV)oxide. These waste gas mixture is used in pre-heating the air blast and the iron ore at the initial stages ...

How is Iron Refined from Ore? (with pictures)

10/02/2021  The heat generated inside towering blast furnaces is used to create pig iron from a mixture of iron ore, coke, and limestone. To create an even purer form of iron, known as pig iron, limestone must be added to the mix and the heat increased. This is done contemporarily in the silo-like structure known as a blast furnace. The calcium in limestone bonds with the silicates in the ore

PIG IRON, CAST IRON WROUGHT IRON – WHAT’S

29/05/2017  The impurities of pig iron are removed to some extent by oxidation. The molten cast iron is led into moulds of required shapes to form what are known as cast iron castings and slag is removed from the top of cast iron at regular intervals. Composition of cast iron: Cast iron contains about 2 to 4 percent of carbon. Manganese makes cast iron-brittle and hard, so it may be kept below 0.75 ...

Ultimate tensile strength of pig iron vary greatly and depend on the form the carbon takes in the alloy. The high level of carbon makes it relatively weak and brittle. Reducing the amount of carbon to 0.002–2.1% by mass produces steel, which may be up to 1000 times harder than pure iron. The ultimate tensile strength is the maximum on the engineering stress-strain curve. This corresponds to ...
