分析了不同D/S值的厚、中、薄壁管在ASSEL轧管机上的螺旋变形特征和壁厚精度。分析表明,随轧后荒管D/S值的增大,壁厚精度下降。ASSEL轧管机具有台肩集中变形、碾轧段壁厚增厚等特点。
The helical deformation characteristics and wall thickness accuracy of thick, medium and thin-walled tubes with different D / S values on the ASSEL pipe mill were analyzed. The analysis shows that the accuracy of wall thickness decreases with the increase of D / S value of slagging tube. ASSEL tube rolling machine has a centralized deformation of the shoulder, rolling thickening of the wall thickness and so on.
