摘要 The profile quality of hot strip will affect the quality of cold strip,therefore,it is one of key quality fields which needs improve.In this paper,three kinds of profile irregular defects of hot rolling strip were discussed based on the production experience.Through profile,rolling,work-roll's wear and simulation methods,this paper discovered the reasons of these quality defects.Meanwhile,the ways to deal with these defects were presented and have been proved effectively.Decrease the number of narrow strips,select the suitable type of spray,set the better angle of nozzle can improve the profile quality of hot strip.
