Abstract：

Abstract: In order to realize the continuous forming of ribbed plate components and improve the quality of ribs， a process method of forming ribbed plate using a two-roller rolling mill was proposed， and the finite element model of ribbed plate rolling was established by finite element simulation software Deform. Then， the process principle was explained， the metal flow deformation behavior and equivalent strain distribution in the rib area and the bottom plate area during the rolling process of ribbed plate were revealed， and the influences of different plate thicknesses and reduction rates on ribbed plate forming were analyzed and studied. The results show that this method realizes the forming processing of thin-walled and high-ribbed components.

The formed rib height of ribbed plate can be improved by adjusting plate thickness and reduction rate. When the plate thickness is less than 8 mm and the reduction rate is less than 60%， the maximum rib height of formed ribbed plate is 1.8 mm. Thus， this research provides a theoretical reference for the rolling process and mold optimization design of such components.
