| Abstract: | This paper introduces the design principal and error analysis of bi-directional hot centering mechanism in rolled tube sets. The major characters are fully hydraulic driving, high strength case frame, adjustment by specified length. The depth of center hole and velocity of center can be adjusted first and bi-directional centering precision can achieve 4 mm. It supplies successful experience for seamless steel pipe factories with important profits and promotional value. |
