Determination of the influence rate of work roll crown

A common method of improving the shape of the plate is to compensate for the shape of the plate by changing the crown of the work roll. This method not only makes the shape of the no-load roll gap more reasonable, but also improves the contact between the work roll and the backup roll, thereby affecting the change in the crown of the strip.

Determination of the influence rate of work roll crown

The basic value of the influence of the work roll crown obtained by the strip crown influence rate simulation software is shown in Fig. 1 (a).

It can be seen that the basic value of the work roll crowning degree decreases with the increase of the strip width, which indicates that the larger the strip width, the greater the influence of the work roll crown on the strip crown. The fitting coefficient of the 5th degree polynomial of the basic value of the work roll crown is shown in Table 1.
