Other known rolling mill configurations similarly employ liner plates of unequal area on the lower and upper work roll bearing chocks. It is a primary object of the present invention to provide an improved chock structure for the work rolls of a rolling mill.
Configurations. Mills are designed in different types of configurations, with the most basic being a two-high non-reversing, which means there are two rolls that only turn in one direction.The two-high reversing mill has rolls that can rotate in both directions, but the disadvantage is that the rolls must be stopped, reversed, and then brought back up to rolling …
Introduce The production of seamless forged rings is often performed by a process called ring rolling machine. These machine vary in size to produce forged rings with outside diameters from 45 mm 1500 mm to and in weights from 0.5 kg up to over 400 kgs.
Three-High Rolling Mills: In this mill, the three rolls stand in parallel one by others. The rolls are rotating in opposite directions. In this mill, between the first and the second rolls, the material passes. If the second roll rotates in a direction then the bottom roll rotates in another direction.
A twohigh rolling mill is the most basic type of rolling mill, consisting of two opposed rolls. The diameters of the rolls in these mills range from 0.6 to 1.4 metres. Reversible or non-reversible two-high configurations are available. The rolls in a non-reversing mill always revolve in the same direction, and the work is always fed from the ...

Rolling mills can have multiple different configurations that are used depending on material type, thickness and yield strengths. Element has built a wide variety of rolling mills to fit multiple applications. 2 High Rolling Mill Experience.
The types of rolling mills based on roll configurations are described below and are shown in Fig 3. Two-high mills – These mills have 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 ...

Modern rolling practice can be attributed to the pioneering efforts of Henry Cort of Funtley Iron Mills, near Fareham in Hampshire, England.In 1783, a patent was issued to Henry Cort for his use of grooved rolls for rolling iron bars. With this new design, mills were able to produce 15 times more output per day than with a hammer. Although Cort was not the first to use grooved …
