Shalco Industries Pvt. Ltd.

The piercing is carried in a plant known as the piercing mill, which consists of a number of dies, of which, two primary contoured work rolls rotate in the same direction with their axes at 3 to 6 degree with respect to the horizontal stock plane. The process is also known as rotary piercing or seamless tubing.

Cross-roll piercing and cross helical rolling QForm

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.

Plugmill Technology - Jindal

Plug Mill Process is a proven process for manufacturing of higher diameter Seamless Pipes by heating round billets up to the plastic stage of steel and piercing in a Cross Roll Piercer. Further elongation is achieved through a Plug Mill in which the thick wall hot hollow is rolled through a pair of Top and Bottom Rolls with a plug inside to control the ID and achieve better internal surface ...

How the Operations of Hot Rolling Mill Works Deem Rolls

14-02-2019  Let’s see how the operation of hot rolling mills works. Knowing the process will allow you to find the right rolling mill rolls manufacturer easily. Steel rolling is the process of reducing the cross-section of large ingots or plates in bulk. The main focus is to produce finished or semi-finished components that have various applications.

ROUND-INGOT PIERCING BY CROSS-ROLLING WITH

round-ingot piercing by cross-rolling with elongator of pilger mill Yin Renjie (Research Group for Round-ingot Cross-rolling Piercing, Chengdu Seamless Steel Tube Plant) The possibility of piercing ingot via cross-rolling instead of hydraulic piercing plus elongating with a pilger mill was studied and also trials of piercing ingot directly on a cross-rolling piercing mill have been made.

Seamless Pipes Manufacturing How to Produce

In plug mill process, a solid round billet is used. The round billet is first heated uniformly in the rotary hearth heating furnace and then pierced. The round billets are pierced using a cross roll piercer. The piercing mill presses the billet against a plug to pierce the billet, and then rolls the

Introduction to Seamless Pipe Manufacturing - The

24-07-2018  The cross rolling causes high tensile stresses at the center of the billet. The design of the piercer rolls causes the metal to flow along the roll and over a piercer point as it exits the process. The piercer point is a high-temperature, water-cooled alloy tool designed to allow the metal to flow over it as a pipe shell forms from the rotary process.

A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING MILL ROLLS

Rolls are tools used in rolling mills to reduce the cross section of metal stock. The weight of rolls may vary from a few kilograms up to 250 tonnes. Under rolling conditions the contact area between roll and stock suffers wear, the other parts of a roll - body and necks - have to be considered as normal parts of designed components under high ...

PLATE MILL — POWER MEETS PRECISION

For the successful plate producer, the mill is more than the rolling stand(s) at its core. Ancillary processes, in cooling and levelling in particular, are vital to quality, and control of the process is the key to efficient asset utilization.

Rolling Process: Types, Working, Terminology and ...

Rolling works on same as any other metal forming process. When a compressive force applied by a set of rolls on ingot or any other product like blooms or billets, plastic deformation takes place which decrease its cross section area and convert it into required shape.
