摘要
对中厚壁钢管在微张力减径过程中出现的内孔不规圆现象进行了研究,分析了内六方和内三角的形成机理,根据生产实践经验,建立了椭圆度方程,并提出了消除内不规圆的措施。
The medium and heavy wall-thickness pipes under the production process of slight stretch reduction on diameter. To analyze the forming mechanism of the inner hexagon and triangle shape. To establish the elliptic equation based on production experiences to put forward measures to diminish bore roundless.
