Fig. 1. A standard roll forming mill is used to do experiments, the roll load is measured with load cells and the roll torque is measured with a torque sensor during a forming of different steels. Table 1 The materials that have been tested are Docol, DC01 (carbon steel) and HyTens, SS2333 (stainless steel) Material Thickness (mm) RP0.2 (MPa ...
The dependences of changing power parameters and piercing time on the friction factor during piercing in a two-roll mill with guards are obtained. With increase of the friction factor, piercing time decreases and torque and rolling power increase. The simulation results are correlated with results of experimental rolling.
