Influence of Diameter Increase Speed on Diameter-Axial Rolling of Large 40Cr13 Stainless Steel Ring

Abstract Rolling speed ratios during the rolling process are critical to ring forming in this pepper. The selected roll feed mode is constant with increasing of diameter main stage. Based on Deform-3D finite element software, a large size φ1530 mm was taken as research object. numerical model 40Cr13 stainless steel established. radial-axial rings under different increase speeds simulated, and changes radial force, temperature, strain distribution after were analyzed speeds. results show that same conditions other parameters, has less effect temperature equivalent standard deviation variation inside rolling, but more external surface, both SDP SDT decrease speed. maximum force obvious, increasing. Using deviation, reference indexes, rate suitable for 6 mm/s.
