Sep 01, 1976· The only serious difficulty as sociated with roll cambers occurred when worn backup rolls with 0.15 mm crown were in stand 5 and attempts were made to roll 1750 mm wide material. This produced bad shape which was beyond the correction range of the roll bending equipment.
A rolling mill stand having a pair of side shiftable rolls defining a roll gap profile therebetween varying along the length of the rolls according to a sixth order polynomial equation. The flatness of the strip exiting the rolling mill stand is controlled by determining the temperature profile of the rolls and adjusting the side shift positions of the rolls to compensate for the expansion of ...
Obtaining the proper degree of crown at the center of the roll is only part of the problem. The second part is obtaining the proper crown contour to match the bending of the roll at each point along the roll face. Present roll grinding equipment is designed to provide crown contours, which coincide with partial cosine curves as seen in Figure 2.
would now put a crown of 0.027-in. into the rubber. If the crown were originally 0.030-in. it would be increased to 0.057-in. If the situation were reversed and the nip at the center (N 1) were 0.9-in. and the nip at the ends (N 2) –0.7
Mar 27, 2014· CVC involves grinding a third order polynomial curve into the work rolls and then shifting the work rolls laterally, equally, and opposite to each other. The effect is that the rolls will have a gap between them that is parabolic in shape, and will vary with lateral shift, thus allowing for control of the crown of the rolls dynamically.

The Tools: Grinding & Polishing. You will need two tools: A hard tool for rough and fine grinding, and a soft tool, or pitch lap, for polishing and figuring. Traditionally, the pitch lap was made on top of the grinding tool. We recommend using plaster disks for tool substrates, and that you use separate disks for these two tools.

contact line between the grinding wheel and the gear tooth, which runs diago-nal over the tooth as shown in Figure 13. Thus all points along this line are generated at the same time. In the case of grinding a symmetric lead crown-ing, a parabolic function x(z), as men-tioned above, will result in a change of radial infeed over the face width ...

Specifying a crown on a roller must be done with precision. This is especially true when grinding or cutting an accurate crown. It is such a difficult process that if the shape/profile is compromised, it will cause more problems than not crowning at all. The amount of crown needed usually is very small and within a magnitude of a few mils (0 ...

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. If the temperature of the metal is above its recrystallization temperature, then the process is ...
Oct 10, 2016· This can be overcome by using a crowned rolls (parabolic crown), however the crowned rolls only compensate for one set of conditions, specifically the material, temperature, and amount of deformation. Other methods of compensating for roll deformation include continual varying crown (CVC), pair cross rolling, and work roll bending.
