iron and steel
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.
23.3: Metallurgy of Iron and Steel
Steel. Much of the iron produced is refined and converted into steel. Steel is made from iron by removing impurities and adding substances such as manganese, …
Iron Extraction by Blast Furnace Metallurgy
Iron extraction is an extremely important process as it deals with building a bridge, house et cetera. Iron extraction is one of the main parts of metallurgy. Iron Extraction Procedure. Iron extraction is considered as an extremely lengthy process that starts from concentration and ends through calcination roasting.
