Good quality steel is made using this method. In this method, steel is made by blasting compressed air from molten iron in which excess carbon and impurities are burnt in a large pear-shaped container. See in the figure Linz-donawitz process arrangement. When the oxygen flow is complete, the foam is removed and the metal is collected in a ladle. This method uses molten pig iron and steel scrap and oxygen is passed through a water-cooled lance for the oxidation of carbon and other impurities.

In this method, a basic oxygen converter is used to make high-quality steel in a relatively short time. Process is a Linz-donawitz process which is developed in Austria in 1949. In this method, a mixture of wrought iron, steel scrap, and ferromagnes is melted with charcoal in an airtight crucible.ĭuring melting the metal absorbs the required carbon from the charcoal and the steel is then filled into ingot molds.Ĭast steel is usually made using this method. These currents are called eddy currents and due to their passing, the steel becomes hot. In high-frequency furnaces, the required heat is generated by an inductor coil with an alternating current.Īn alternating magnetic field is generated by the electric current generated in the steel. In an electric arc furnace, the required heat is generated by striking an electric arc between carbon electrodes and a metal bath. Usually, the following two electric furnaces are used. See in the figure the electric process arrangement. The temperature can be easily controlled and regulated at all times.Īlloy steels like stainless steel, high-speed steel, etc are made using this method. In this method, only electricity is used to generate heat. See in the figure the open hearth process arrangement. Using this method, mild steel and medium carbon steel are made by removing carbon from iron. When the metal bath reaches the required amount of carbon, tapping is done with the furnace. The temperature inside the furnace is about 1500 ☌.ĭuring melting, some part of the carbon, mostly silicon and manganese, is removed by oxidation. In this method, the pig iron and steel scraps are melted and refined at the hearth by the heat of the fuel burning.

The melting zone is connected to the generator by ports. The following six methods are used in the process of manufacturing steel.Īn open hearth is a shallow hearth around which the roof and wall of refractory bricks are made.Ĭharging doors are mounted on the side of the walls.

Steel is an alloy of iron and carbon in which the carbon content varies up to 1.5%. So without wasting time let's get started What is Steel? Steel is a multi-purpose alloy with many applications such as it is used in construction, automotive, aircraft industry, heavy industrial equipment, transportation infrastructure, home appliances, etc. Hello, friends today I am going to discuss the manufacturing process of steel in which you will learn different methods of making steel.
