Numerical simulation of multi-pass rolling force and temperature field of plate steel during hot rolling

Abstract: Rolling force and temperature field are important parameters in the hot rolling process of plate steel. Most researchers use ANSYS/LS-DYNA and MSC.Marc to simulate the hot rolling process, however, software DEFORM-3D is not used widely in this field. Therefore, in this study, the commercially available finite element analysis software DEFORM-3D is used to simulate the distribution of rolling force, stress-effective, strain-effective and temperature field during the hot rolling process of plate steel with the s… Show more

“…The rolling speed during the final pass is increased from 10 m/min to 130 m/min, and the speed changes dramatically. The process of speeding up the mill after coiling leads to a significant thinning of the strip thickness difference [28]. The distance between the roll gap and the thickness gauge is 2.6 m, while the distance between the beginning of the speed-up point and the beginning of the thinning point is calculated to be about 2.2 m, with a difference of 0.4 m. The distance between the roll gap and the thickness gauge leads to the thickness thinning and lagging behind the mill speed-up.…”

“…According to the thermal imager, the temperature decreased by more than 150 K. The expression of contact heat conduction between the bead and the roller is as follows: where q is the heat flux density, λ is the heat transfer coefficient, α is the heat transfer coefficient, T is the surface temperature of the bead surface and T g is the roller temperature. The contact heat transfer coefficient before the weld bead and the roller ranges from 25 to 75 kW/(m 2 K) depending on the research (Zeng et al , 2011). The model outlined in the present paper has been repeatedly verified to be 50 kW/(m 2 K).…”
