Discussion on Roll Profile Curve Design of 6-roll Straightener

Basing on the seamless steel pipe straightening theory and practical production, a full-contact profile curve design method for the 6-roll straightener is summarized. Relationships among different parameters are analyzed, and a roll profile curve formula is derived by mathematical method. The practice indicates that the roll produced by using this profile curve design method is in good contact with the seamless steel pipe, and su the abrasion resulting from straightening is reduced. The straightened pipe has a surface quality and a straightness meeting the requirements of produciton, and it performs well in real application.
