Online 3D line-laser detection and physics-guided asymmetric cooling control of C-warp in hot-rolled strip laminar cooling

Case Studies in Thermal Engineering
Widthwise C-warp in hot-rolled strip may develop or intensify during laminar cooling because of asymmetric heat transfer, through thickness temperature gradients, and inherited shape defects. This industrial case study presents a measurement assisted and

Review on Cold Rolling Mill Roll Deformation

MATTER: International Journal of Science and Technology, 2017
There are various reasons by which the damage in the cold rolling mill rolls occurs. The main objective is to highlight those reasons which are responsible for the breakage. The parameters considered during the manufacturing and during the regular use of rolls in cold rolling in the past researches and the effect of these parameters to increase the ...

Characteristics of Sialon Ceramic Rolls in Cold Rolling.

ISIJ International, 1992
The use of ceramics has been studied to provide rolling performance levels that conventional steel rolls can never attain. Sialon was selected as the most suitable roll material for cold rolling. Its characteristics and performance in cold rolling were evaluated.Mechanical properties, especially flexural strength, were lower than for steel rolls ...

Lubrication in cold rolling

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.
