Cementation process
Crucible process
Bessemer process
Open hearth process
Answer is Right!
Answer is Wrong!
The correct answer is A. Cementation process.
The cementation process is a method of manufacturing steel by carburizing wrought iron. It is a form of case hardening, where a thin layer of steel is created on the surface of a piece of iron by heating it in contact with carbon. The carbon diffuses into the iron, making it harder and stronger.
The cementation process can be used to produce a variety of steels, with different properties depending on the amount of carbon that is added. Softer varieties of steel can be obtained by using a lower concentration of carbon.
The other options are incorrect because they are all methods of manufacturing steel that produce a harder and stronger product.
- The crucible process is a method of melting iron and steel in a crucible, which is a container made of a material that can withstand high temperatures. The molten metal is then poured into molds to create ingots or castings.
- The Bessemer process is a method of manufacturing steel by blowing air through molten pig iron. This removes the impurities from the iron and produces a high-quality steel.
- The open hearth process is a method of manufacturing steel by heating pig iron and scrap iron in a furnace with a large open hearth. The impurities from the iron are removed by oxidation, and the molten metal is then poured into molds to create ingots or castings.
