Mechanics of mixed film lubrication in strip rolling. Rolling speeds of tandem cold rolling mills for thin steel strip are often limited by hot scratches and self excited chatter vibration, which forces the mill to slow down. Consequently the output is reduced and significant out-of-specification materials produced. Operating practices are guided by experience and trial-and-error method. In this project, a comprehensive model will be produced to quantify the effects of relevant parameters that c ....Mechanics of mixed film lubrication in strip rolling. Rolling speeds of tandem cold rolling mills for thin steel strip are often limited by hot scratches and self excited chatter vibration, which forces the mill to slow down. Consequently the output is reduced and significant out-of-specification materials produced. Operating practices are guided by experience and trial-and-error method. In this project, a comprehensive model will be produced to quantify the effects of relevant parameters that can provide a much better understanding of the rolling process at speeds higher than previously possible, and help to improve its productivity as well as product quality.Read moreRead less

Roll bite lubrication in hot strip rolling. Roll bite lubrication has been applied in hot strip rolling with significant cost savings in reduced rolling force, reduced roll wear and increasede productivity. However the mechanics of roll bite lubrication in the interface is not well understood due to the high temperature of the strip, scale oxide on the surfaces and contact asperities. It is known how the surface roughness is generated after rolling. This proposed project will develop a model to ....Roll bite lubrication in hot strip rolling.

The outcome would be significant cost savings in reduced rolling force, increased roll life, minimal surface defects and increased productivity.Read moreRead less
Tribological contact of work roll in hot rolling. Steel and aluminium manufacturers form their products by shaping a hot metal billet using, for example, presses and rollers which contact the rapidly cooling metal in the production line. The economic benefits of lubrication, reduced rolling force (up to 25%), reduced roll wear and extended roll life (up to 40%), reduced down time due to roll change, and better strip quality are very significant for these manufacturing processes. This comprehens ....Tribological contact of work roll in hot rolling.
