rolling (metalworking) - wikipedia

In metalworking, rolling is a metalformingprocess in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough.Rolling is classified according to the temperature of the metalrolled. If the temperature of the metal is above its

welded roll forming system versus tube mills: what's the

In the classic sense, a tubemillis a kind of welded roll form system; however, not every welded roll form system is a tubemill. Tubemillsare welded roll form systems that have been fine-tuned to run a specific diameter range, typically at fast speeds (see Figure 1 ). Diameter range is mentioned because a tubemillwelds a round product
