  • Cross-roll piercing and cross helical rolling QForm

    Cross-roll piercing belong to the incremental process class where deformation occurs in a small localized area of the workpiece and the workpiece itself is processed sequentially to obtain a finished product. It is possible to identify the formation of the cavity and the zone where ductile fracture is occurring by estimating the stress-strain state using the QForm software.

  • 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.

  • WorldOfSteel Manufacturing Process of Seamless Pipes

    Following high-pressure waterjet descaling, the bloom is pierced in the cross roll piercing mill to produce a thin-walled hollow shell which is elongated to between 3 and 4.5 times its original length, corresponding to a deformation level of between 65 % and 75 %.

  • Teaching an old piercing mill new tricks The FABRICATOR

    Many seamless tube producers in North America use cross-roll piercing mills built in the 1950s that were based on designs from the1930s. While it would be advantageous to replace such aged equipment, that isn't always necessary. A minor equipment upgrade can do wonders. Improving the bar steadiers—the devices that hold the mandrel the steady as the pipe exits the mill—can greatly

  • Online Eccentricity Monitoring of Seamless Tubes in Cross

    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.

  • Minimizing wall thickness variation in seamless tubing

    Guidelines for Cross-roll Elongation. For cross-rolling elongation, two main requirements relate to the as-pierced shell. These are filling the hump height section to 80 to 90 percent of its design and maximizing inlet side grip. Both requirements are related to the roll pass design in the Assel mill.
