responses to the changes of force in the rolling mill. The shape and the high quality construction of the Mill Master Load Cells make them highly suited for the metals rolling mills where they are engineered and fitted for measurement and control of roll forces for automatic gage control.
The maximum possible draft in a rolling operation depends on which of the following parameters (two correct answers): (a) coefficient of friction between roll and work, (b) roll diameter, (c) roll velocity, (d) stock thickness, (e) strain, and (f) strength coefficient of the work metal?

The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.

the rolling mill shown in figure 4 care of the rolling mill. do not roll any hard and the turning action of the mill, but instead depends on force directed
Mechanics of Cold Rolling of Thin Strip 443 where yiw is the vertical deflection of the work roll at element i, gijw (, ) is the influence function for the work roll deflection due to the combined bending and shear forces generated by rolling load, giwf is the influence function for the work roll deflection due to the force generated by the roll bending mechanism, k represents the minimum element
Fig. 1.7.1: Rolling mill control From the above curves, we could understand the control of rolling mill. The solid curve, called plastic curve, represents the variation of rolling load with rolled thickness. As thickness reduces, roll force increases. This was shown earlier. The solid line represents the elastic deformation of the roll.
