Tube Roll Design JMC Rollmasters

Tube roll design is an organized process culminating in the production of a roll formed welded metal tube. First consideration is the products’ specific characteristics of size, shape and physical properties. The next consideration is the forming and welding machinery available to the producer.

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.

Rolling (metalworking) Wikipedia

2020-5-20  Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.
