1. Hot rolling and rolling defects: 1.1 Front and back

the rolls get deflected by high rolling forces. Elastic deformation of the mill takes place. If we use stiffer rolls, namely roll material of high stiffness or elastic constant, we could avoid mill spring. Normally elastic constant for mills may range from 1 to 4 GNm-1. Roll elastic deformation may result in uneven sheet thickness across.

HYDRAULIC CIRCUIT DESIGN AND ANALYSIS

The power developed by a hydraulic cylinder for either the extension or retraction stroke, can be found out by (velocity multiplied by force) or from ( flow rate multiplied by operating pressure ) Power ( kW ) = vp ( m / s ) * F ( kN ) = Q ( m3 / s) * p ( kPa ) Figure 5.4 shows a circuit used to control a double – acting hydraulic cylinder.

Headboxes

Originally, the pressure to accelerate the stock to the speed of the paper machine was supplied by a hydrostatic head of liquid. But as Fig. 5.5 shows, high speed paper machines require too much pressure for this to be practical, so paper machines now use closed, pressurized headboxes to supply the necessary pressure. Paper machines operating above 2500 ft/min require a special, high pressure
