In the hot rolling process, metal is heated and passed through one or more sets of rollers, to give it the desired cross-section for example. This process is used for the fabrication on railway tracks (Figure 1).
As you may have noticed, we're working on kind of a series of blogs on the simulation of different production techniques. This time, we will look at roll forming.
During the roll forming process, a long strip of sheet metal is continuously bent into the desired cross-section. The strip passes through a number of sets of rollers, where each set performs a part of the total desired bend, until the final profile is obtained.
