Objective
The current trend of cold tandem mills of combining higher rolling speed, larger reduction, harder steel grades significantly increase problems of cooling and lubrication degradation.
This project aims at improving cooling performances to make better lubricant properties in cold rolling. Physical models associated to tests of new cooling techniques (combination of different types or arrangements of nozzles, high turbulence cooling techniques) will be derived in practical recommendations to improve cold mills productivity and product quality.
The expected benefits for the European steel industry are estimated to 15M�/year through the possibility to achieve higher rolling speeds and reductions, to decrease oil consumption (by 5%) and oil cost (by 15%), and to reduce water consumption and recycled coolant quantities (positive environmental aspect).
