摘要

对进料角为 6、12、18 和 24°的不锈钢坯料的双螺旋轧制进行了数值模拟。结果表明，增大轧辊的进给角会减小钢坯横截面上剪切应变的大小和不均匀性。随着进给角的增大，变形过程中钢坯表面和中心总速度区之间的差值减小了 57%，几何变形区的长度减小，实际变形区的长度增加了 16%。

Assessment of shear strains, kinematic state, and deformation zone in two-high screw rolling processes

Two-high screw rolling of stainless-steel billets at feed angles of 6, 12, 18, and 24° was numerically simulated. It was established that increasing the feed angle of the rolls decreases the magnitude and inhomogeneity of the shear strains in the billet cross-section. With increase in the feed angle, the difference between the total velocities zone on the surface and at the center of the billet in the deformation decreases by 57%, the length of the geometric deformation zone decreases, and the length of the actual deformation zone increases by 16%.
