1 天前 Cast iron has already been mentioned above. This section deals with the types of iron and steel which are produced as a result of the steel-making process. Wrought iron. If all the carbon is removed from the iron to give high purity iron, it is known as wrought iron. Wrought iron is quite soft and easily worked and has little structural strength.

iron oxide + carbon monoxide → iron + carbon dioxide Fe 2 O 3 + 3CO → 2Fe + 3CO 2 Iron from the blast furnace is an alloy of about 96 per cent iron with carbon and some other impurities. It is hard, but too brittle for most uses. So, most iron from the blast furnace is converted into steel by removing some of the carbon. Show Video

This is even harder than pig iron. Wrought Iron/ Malleable Iron. Wrought iron is the purest form of iron available commercially available and is prepared from cast iron by heating cast iron in a furnace lined with Haematite (Fe2O3). The Haematite reacts with Carbon in the cast iron to give pure iron and carbon monoxide gas which escapes.
Read MoreThe Earth's crust contains a lot of iron, about five per cent of its mass. But the iron found in nature is never in pure form. The iron is always bonded together with other elements, in chemical compounds. One common iron compound consists of iron and oxygen - iron oxide. You can extract the pure iron, by heating the iron oxide together with coal.
