  Starting material for getting steel is iron ore. It is then converted to hot metal in a blast furnace. Further treatment is done in steel melting shop to get required quality. Final product is obtained as slab, having a width of 150–210 mm with thickness of 150 mm. This slab is carried to Hot Rolling Mill in the ambient temp and is further heated in a furnace, then rolled to thinner section, such as 2 -10 mm. It takes a form of coil. This coil is transported to cold rolling mill in cold condition where it is reduced in cold rolling mill, between 0.2 to 3 mm. There are various types of cold rolling mills. They may be 4-high, 6-high, 20-High mill. Mainly, rolling takes place between two working rolls. Rest are back up rolls to give support the working rolls. Back up rolls give support to maintain uniform thickness, rigidity to work roll, maintaining proper shape of final product. The property of cold rolled sheet varies with hot rolled sheet. Cold rolling induces increase in strength,

       Our modern world cannot subsist without Electricity. Since centuries efforts has been made to convert Mechanical energy to Electrical energy. Technology was invented to transmit the electrical energy that was created from one place to another. Then came the Grids which could distribute the electrical energy which was termed “Power”. As our worldly requirements began to expand, the need for Electrical Power also increased in our society. The growth depended on the development of new appliances which supported our livelihood. One of them was the section which included the use of Electrical Power by using efficient transformers, generators and motors. The first step toward making these ecological and technological advancements is the development of more efficient Electrical Steels. Electrical Steel is an essential component for electromagnetic machines. It is used to create magnetic cores that help power transformers, power generators, and more. It is called by many names Laminatio
