| Abstract: | The operating conditions of work rolls of the finishing mill for producing hot rolled strips in Angang are introduced,and then the main factors which influence the service life of the work roll are analyzed.Based on that some concrete improvement measures are proposed,including ensuring sufficient cooling water,adding hot rolled oil,selecting the appropriate temperature for placing work rolls.By taking these measures the wear extent and spalling of rolls are reduced,and also the probability that the rupture occurs on the roll are reduced.And thus the service life of work rolls can be improved. |
