Rolling (metalworking) Wikipedia
In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough.Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is

Stretching, reducing on a tube or pipe mill
A conventional forge welding mill already includes sizing stands to reduce the tube to its final size, normally a 1 percent reduction. Adding a few roll stands and using the cold-stretch-reducing (CSR) process can expand this mill’s capability, enabling reductions of more than 50 percent. This always the mill to make brake and fuel lines for automobiles; coolant lines for refrigerators
US Patent for Stretch-reducing mill for rolling tubes
A stretch-reducing mill comprises a plurality of rolling stands laid side-by-side between an input stand and an output stand. A first group of stands adjacent to one another is next to the input stand and a second group of stands adjacent to one another is next to the output stand. The first group of stands is operated through a differential drive with two motors; the second group of stands is

A commonly used method is to take the elastic
Understanding Rolling Process in Long Product Rolling
High tension can stretch reduce the cross section of the bar making shape control very difficult. At the extreme, tension can pull the bar apart, creating a cobble. Compression of the bar between stands can create flutter creating defects, or at the extreme will cause loop growth leading to a cobble. Using the working diameter of the rolls, the roll rpm (revolutions per minute) is matched to
The basics of roll form tooling design
You can successfully roll-form a profile more than one way. In fact, many roll form designers take different approaches to design and development. Also, because the roll forming process has a seeming limitless capacity to produce complex profiles with just as many variables, many roll form designs are one-of-a-kind; therefore, theory can go only so far.
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 load. This means that necks should not experience

Cut-To-Length (Temper Mill & Leveling) Integrity
The science behind the temper mill involves compression, or rolling, the stainless through what is known as a cold reducing process, temper pass. This increases the density of the steel by reducing its overall thickness by around 1.5% to 2%, consequently, not allowing the steel to expand under pressure. The stainless steel coils that are run through the temper mill go through a fairly simple
