23.3: Metallurgy of Iron and Steel

The first step in the metallurgy of iron is usually roasting the ore (heating the ore in air) to remove water, decomposing carbonates into oxides, and converting sulfides into oxides. The oxides are then reduced in a blast furnace that is 80–100 feet high and about 25 feet in diameter (Figure (PageIndex{2})) in which the roasted ore, coke, and limestone (impure CaCO 3 ) are Get price

Metallurgy

The actual reductant is CO, which reduces Fe 2 O 3 to give Fe(l) and CO 2 (g); the CO 2 is then reduced back to CO by reaction with excess carbon. As the ore, lime, and coke drop into the furnace (Figure 23.7 A Blast Furnace for Converting Iron Oxides to Iron Metal), any silicate minerals in the ore react with the lime to produce a low-melting mixture of calcium silicates Get price

18/2/2021The treated ore is then put in a large bath of water containing a ing agent (a soap or detergent of some kind), and air is blown through the mixture to make a lot of bubbles. Because they are water-repellent, the coated particles of the metal compound tend to be picked up by the air bubbles, float to the top of the bath, and are allowed to flow out over the sides.Get price

How Iron Feels the Heat

These same principles also determine how atoms in solids are arranged, and in the case of iron, nature changes its mind several times at high temperatures. At room temperature, the iron atoms are in an unusual loosely packed open arrangement; as iron is heated past 912 degrees Celsius, the atoms become more closely packed before loosening again at 1,394 degrees Celsius and Get price

Cast iron is different from pig iron and is made by melting pig iron with scrap iron and coke using hot air blast. It has slightly lower carbon content (about 3%) and is extremely hard and brittle. Wrought iron or malleable iron is the purest form of commercial iron and is prepared from cast iron by oxidising impurities in a reverberatory furnace lined with haematite.Get price
