| Abstract: | In view of work roll surface oxidation film abnormal spalling,bad effect of cooling and rolling lubrication of work roll of F1~F4 stands in a 1 780 mm hot strip rolling line,the media system used for entrance and export guide and guard of F1~F4 stands was reformed.By rearranging the descaling pipes at the entrance and export of F1~F4,redistributing the cooling water amount and improving lubrication rolling,the stable oxide film of roll was establisehed,roll consumption was reducd,and the quality of the product surface was improved. |
