Fig 4 Roll configurations in rolling mills. Twohigh mill roll configuration This is the most commonly used rolling mill configuration. In this configuration, there are two horizontally mounted rolls. The rolling mill motor drives either both rolls (top and bottom) or only one roll (normally the bottom roll) with the top roll rotating due to the friction between the roll and the work piece.

In the Rolling Mill unit, the largest consumption of electricity is in the bar mill, typically contributing 20% of the plant's total electrical energy consumption. The conventional rolling mills in India are producing a major part of structural steel requirement of the country. The energy conservation in these rolling
Rolling mills are machines that shape metal by passing it through two rolls. They are used to flatten and reduce metal to a sheet or plate. Most rolling mills feature two or more rolls arranged in a symmetrical pattern, with half above the work and half below the work to be rolled. Typically, the rolls are mounted one above the other and rotate ...
