| Abstract: | The hot rolling production approach for TP110-SUP13Cr thin wall oil casing by 168PQFmill is introduced. 151 pass was adopted to reduce rolling force and total elongation coefficient. Mixedrolling with carbon steel was applied to alleviate the sticking on the tool and to improve internal andexternal surface quality. Specified billet heating system was adopted to realize thorough heating of thebillet. Process parameters for piecing and continuous rolling were adjusted reasonably to effectivelyavoid rolling block and blank pipe lamination and to lift rolling stability. |
