4 High Rolling Mill - Element
Rolling mill consisting of four rolls or known as a 4 High rolling mill is used for reducing material to extremely small thicknesses. Through the use of larger backup rolls, the issues of roll deflection can be avoided and smaller work rolls can be used. This reduction in work roll diameter: Reduces overall separating force required for reductions
Research and Application of Non-symmetrical Roll Bending ...
kinds of non-symmetrical roll bending control on the pressure distribution between rolls were studied theoretically.

The multiple pyramid mandrel is made from a solid forged alloy steel shaft having higher section modulus which also acts like a pull rod.
What Is A Rolling Mill? | Metal Processing Machinery ...
What Is A Rolling Mill? In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.
