陈红卫, 闫志波, 刘瑞宁, et al. Finite Element Analysis on Internal Stress of Rolling Workpiece of GCrl5 Bearing Steel[J]. Special Steel, 2007, 28(4): 18-20.DOI:
The internal stress of worfcpiece of GCrl5 bearing steel 300 mm x 220 mm cast billet during 1 ~ 4 pass of 650 mill with box pass rolling has been simulated by using finite element analysis software DEFORM and the effects of side taper and rolling temperature on stress were analyzed. Results showed that the first pass with minimum l/[(H + h)/2

value was disadvantaged to improve internal quality of steel products; the less side taper the less tensile stress (σ
x
) at width direction ; and the fracture factor of each point during rolling at 1 050 °C. was less than that at 1 100 °C.
