Lubrication of hot-strip-mill rolls - ScienceDirect

1973-2-1  LUBRICATION OF HOT-STRIP-MILL ROLLS 205 To avoid problems with front-end entry the oil was switched on by a signal from the main-drive motor load and switched off before the tail end had passed through the mill by similar means. In this way time was allowed for the oil to "burn on" the rolls before the next slab was ready for processing.

New lubrication technology for the hot strip mill

2020-5-22  new method for lubricating the work rolls during hot rolling has been successfully tested on the finishing mill of ArcelorMittalDunkerque. The technology sprays low amounts of unemulsified natural oil without additives onto the work rolls using air atomi-sation, lowering the rolling forces by up to 20% and increasing efficiency of use of oil by 50% in comparison with emulsions.

The effect of lubrication on mill loads during hot

2001-1-1  Williams introduces industrial results concerning hot strip mill gap lubrication, indicating that the presence of lubricants between the roll and the strip reduces friction and therefore increases roll life, improves strip surface quality and reduces power consumption. Williams points out that according to various European, American and Japanese sources the use of lubricants in the hot rolling process reduces the power consumption and the rolling loads by 15–25% and increases roll

The Effects of High-Speed Steel Roll and Lubrication

2020-2-5  High-speed steel (HSS) work rolls and rolling lubrication are applied to the mill to improve roll wear and fatigue. Tests show that HSS work rolls manifest good performance in wear, fatigue and oxidation resistance during electrical steel hot rolling. The wear loss of HSS work rolls decreases remarkably, but the heat dispersion deteriorates.

New lubrication technology for the hot strip mill ...

2010-1-27  The use of lubrication during hot rolling presents a lot of advantages. One of the main advantages is the considerably high reduction of rolling force, which leads besides the energy saving (up to 15%) to a reduction of roll wear (longer rolling campaigns and roll lifetime). Product surface quality is greatly improved by a decrease of shearing forces in the roll gap and it can also be used for ...
