采用在主轧管机之前设置延伸机轧管工艺提高钢管尺寸精度

IMPROVEMENT OF STEEL-PIPE DIMENSIONAL ACCURACY BY EMPLOYING ELONGATOR BEFORE MAIN TUBE-ROLLING MILL

本文在分析影响钢管壁厚不均的因素的基础上进行了改善钢管壁厚精度的工艺探讨和分析了我国目前钢管生产技术水平并提出了改进的意见。

An approach to improving wall-thickness accuracy has been made, and the present circumstances of steel pipe production technology in China is analysed, and hence suggestions for improvement offered based on the analysis of factors leading to wall-thickness nonuniformity of steel pipes.
