Analysis of section plastic deformation of 304 stainless steel plate rolled by four-working high mill
Aiming at the problems of large deformation amount and unstable size of 304 stainless steel plate rolled by four-working high mill,the finite element model of four-working roll rolling system was established by Solidworks software,and the rolling simulation of 304 stainless steel plate was carried out with different roll diameters,roll rotation velocities and roll reductions by Deform software.The effects of roll diame-ter,roll rotation velocity and roll reduction on the section height and equivalent stress distribution of rolled piece were analyzed.According to the analysis results of rolling simulation,a four-working high mill was designed and manufactured.The section height of rolled piece were com-pared and analyzed between simulation and production under different reductions.The results show that the plastic deformation of the rolled piece section is mainly divided into interation zone Ⅰ,transition zone Ⅱ and deformation zone Ⅲ.The equivalent stress,equivalent strain and section height are the largest in zone Ⅰ,the smallest and change steadily in zone Ⅲ,and the value of zone Ⅱ is located between zone Ⅰ and zoneⅢ and presents a U-shaped distribution.
