摘要
通过有限元模拟针对斜轧穿孔过程中毛管的变形特点,对其壁厚不均进行了计算。应用自制的管形测量仪,对某钢铁公司穿孔毛管进行了成批测量。将理论与实测值通过FFT变换后进行比较,模拟与实测结果具有良好的一致性。通过模拟不同的工艺参数预测毛管壁厚不均程度,从而达到寻找合理工艺参数的目的。
Addressing deformation characteristics of the shell during rotary piercing operation, wall thickness unevenness is calculated by means of the FE simulation method. With a gage-measuring meter especially designed by the researchers, measurement of pierced shells by a specific steel mill was conducted on a batch basis. Then a comparison between the theoretic values and the measured values is made via FFT conversion, showing full compliance of the simulation values with the measured ones. It is therefore concluded that various technological parameters can be simulated to anticipate the unevenness of the shell wall thickness so as to set up the proper technological parameters as desired.
