Lubrication in cold rolling [PDF]

Wear, 1993
A model has been developed with respect to hydrodynamic lubrication in cold rolling. The basic model describes the configuration of a rigid, perfectly plastic sheet rolled by a rigid work roll. The governing equations have been solved throughout the complete contact area, i.e. the inlet, the work zone and the outlet zone.

Intelligent Recognition Model of Hot Rolling Strip Edge Defects Based on Deep Learning

Metals, 2021
The edge of a hot rolling strip corresponds to the area where surface defects often occur. The morphologies of several common edge defects are similar to one another, thereby leading to easy error detection.
