New lubrication technology for the hot strip mill

5m alongside the mill. An oil flow rate with a minimum of 60ml/min and a maximum of 120ml/min can spread over a roll width of 1.5m and achieve a plate out of 0.4 to 0.8g/m. The prototype was implemented on the top work roll of stand F2 in the hot strip mill at ArcelorMittal Dunkerque (Fig 4). Twelve noz-zles were used to lubricate the work
