摘要

采用有限元分析软件DEFORM

对石钢GCr15轴承钢300 mm×220 mm铸坯650轧机箱形孔轧制1～4道次轧件内部应力进行模拟

分析了侧壁斜度和轧制温度对应力的影响。结果表明1/[(H+h)/2

]

最小的第1道次不利于改善钢材的内部质量;侧壁倾角越小

宽度方向的拉应力(σ

)越小;1050℃轧制时各点断裂因子小于1100℃各点断裂因子。

Abstract

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

) at width direction ； and the fracture factor of each point during rolling at 1 050 °C. was less than that at 1 100 °C.
