Rolling is the process of plastically deforming metal by passing it between the roles. The rolling process is basically used for reducing the crosssectional area of the metal stock. (The width is the same but there is a significant reduction of thickness). It is the most widely used forming process and it provides high production with very ...

In the classic sense, a tube mill is a kind of welded roll form system; however, not every welded roll form system is a tube mill. Tube mills are welded roll form systems that have been finetuned to run a specific diameter range, typically at fast speeds (see Figure 1 ). Diameter range is mentioned because a tube mill welds a round product.

S104. In summary, roll forming can produce AHSS parts with steels of all levels of mechanical properties and different microstructures with a reduced R/T ratio versus conventional bending. All deformation occurs at a radius, so there is no sidewall curl risk and overbending works to control angular springback.

Rolling schematic view Rolling visualization. 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, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of is classified according to the temperature of the metal rolled.
