Piercing Operations Interfaced With A Tube Roll Mill

The results in this example were obtained using a model piercing-rolling mill under the operation conditions given above. Actual mills generally require a roll toe angle γ of 10 to 30 , a billet diameter of 150 to 380 mm, a roll diameter of 900 to 1500 mm, and a disk roll diameter of 1500 to 3500 mm

pierce-rolling process | Salzgitter AG Geschichte

The pierce-rolling process, which was patented in 1886, made it possible for the first time to roll a thick-walled seamless hollow body from a solid steel billet.. To do this, the billet is heated to between 1200 and 1300 C and then positioned between two rolls arranged at an angle to each other and operating in the same direction, thus locking the billet into a kind of gear mechanism

Rolling (Bulk Deformation Process) | Rolling (Metalworking

Rolling consists of passing metal between two rollers, which exert compressive stresses, reducing the metal thickness. Circular shapes, 'I' beams and railway tracks are manufactured using grooved rolls. Rolls rotate with a surface velocity that exceeds the speed of the incoming metal, friction along the contact interface acts to propel the metal forward

Online Eccentricity Monitoring of Seamless Tubes in Cross

Apr 01, 2015 Wall-thickness eccentricity is a major dimensional deviation problem in seamless steel tube production. Although eccentricity is mainly caused by abnormal process conditions in the cross-roll piercing mill, most seamless tube plants lack the monitoring at the hot piercing stage but only inspect the quality of finished tubes using ultrasonic testing (UT) at the end of all manufacturing processes

Rotary Tube Piercing - Manufacturing Process

Rotary Tube Piercing - Manufacturing Process

Rotary tube piercing manufacture relies on this physical principle. A round stock is center drilled at its end and compressive forces are applied by the use of two rolls. A mandrel is used to shape and size the internal cavity formed at the center of the round stock. The rolls rotate in the same direction and are oriented at an axis that is at a slightly skewed angle to the axis of the part

Such rolling processes can be performed on three-high rolling mills and two-high rolling mills. A characteristic feature of cross-roll piercing (rotary tube piercing) and cross helical rolling (three-roll skew rolling) is that metal continuity failure occurs after some reduction of the diameter and this crack propagation forms the cavity in the central part of the workpiece
