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

All kinds of critical mechanical parts in the steel mill are susceptible to water contamination. These parts include roll necks, journals and roller bearings. Therefore, it is important to use lubricants that can effectively handle wet environments and resist quick degradation of quality due to the formation of emulsions, accelerated oxidation and other factors

gauge mills, while direct application systems are mainly applied to high-speed rolling mills for thin steel strip. In recirculation systems, 1–3% steady emulsion is used in the same system for the functions of lubrication and cooling. In direct application systems, 5–15% emulsion is used for lubrication, and water is used for work roll cooling

Dec 03, 2015 The primary function of the conventional hot strip mill (HSM) is to reheat the semi-finished steel slabs (rolled or continuously cast) to the rolling temperatures and then to roll them thinner and longer through a series of rolling mill stands driven by large motors and finally coiling up the lengthened steel sheet for its easy handling and transport

A synthetic water-based lubricant, used in the cold rolling of an Al- alloy, showed good lubrication capability, better than the mineral oil but worse than the emulsion. The rolled Al- strip finish was found to be finest for the synthetic lubricant followed by the mineral oil and the emulsion. Similar results were obtained from the steel rolling

Feb 05, 2020 Work rolls in the hot strip mill withstand extreme service conditions, especially when electrical steels are rolled, resulting in severe roll wear and fatigue. 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
