calculation of speed of roll in stretch reducing mill

1638 2014, 6, Open Access Research and ...
measurements at the rolling mill stand as the basic one. Strip thickness differs from roll position because of various mill housing deflections and roll deformations, which are compositely known as "mill stretch". The total roll force of the stand reacts to this mill stretch but also reacts to changes in the mill stand.

Abstract. Abstract: This work shows the methodology regarding the calculation of the deformation resistance and of the required energy and power for hot reducing of tubes on a stretch reducing mill (SRM) with the final aim of an optimal sizing of the mill drives.
The Basic Theory of Crowning Industrial Rollers
applied to the roll in its particular application. Therefore, roll crowning is one common Therefore, roll crowning is one common method of reducing the nip variation caused by roller deflection.
Roll Crushers, What Are These Machines Mine
Roll crushers have a theoretical MAXIMUM reduction ratio of 4:1. If a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 1/2 inch. Roll crushers will only crush material down to a minimum particle size of about 10 Mesh (2 mm).
