how does a steel rolling mill works?

Answer 1

A rolling mill is a machine or factory for shaping metal by passing it between a pair of rolls.

Rolling mills are often incorporated into integrated steelworks, but also exist as separate plants and can be used for other metals, and other materials.

Rolling mills historically have been of several kinds:

Depending on the temperature of the metal being rolled, rolling mills are typically hot or cold rolling mills.
A slitting mill was used to cut flat bar iron into rods for nail-making.
A tinplate works normally contained at least two rolling mills, one for hot rolling and the other for cold rolling single plates, prior to tinning.
From the Industrial Revolution, puddled iron, after consolidation with a powered hammer (shingling), was rolled into bar iron using a rolling mill with grooved rolls. The grooves provided were progressively smaller, so that on successive passes through the rolls, the cross-section of the bar became smaller and the bar itself longer. By designing the rolls appropriately, it is possible to obtain iron or steel with various cross-sections, including I-shaped girders and railway rails.

Answer 2

Rolling mill machines are based on rolls(also called as forged rolls or steel forged rolls, or rolling mill rolls) which are used to press the metal products to make their thickness uniform. Apart from this it also decrease the width of the objects and increase the surface area of the metal objects.

My dad did this for years.
He had to pull a molten mass of steel from a blast furnace with tongs. Sparks flew all over him. He came home many times with burns on his chest, arms, legs, when those sparks burned through his clothing.
The steel mass was put on a bed and rollers made it flat for sheet metal etc.
Automatic machinery does the job today.
This is very brief.
