摘要
为了进一步改善无缝钢管生产工艺,开展斜轧无缝钢管壁厚偏心控制及工艺优化分析。通过实测测试对无缝钢管轧制标记,利用轮锯法将无缝钢管锯切成便于检测的管段,使用测微计测量其圆周和纵面线相交部位壁厚参数。研究结果表明,无缝钢管壁厚度在横断面上出现偏心,在长度方向上呈现螺旋扭曲,造成壁厚不均匀。偏心率受无缝钢管壁厚和热偏心率的影响较为明显,辊轴速度和辊肩高度会造成管壁厚度偏心率发生负向变化。该研究有助于提高轧制设备的控制精度,为后续工艺优化奠定一定的基础。
In order to further improve the production process of seamless steel pipe,the wall thickness eccentricity control and process optimization analysis of cross-rolled seamless steel pipe were carried out.The seamless steel pipe is marked by the actual test method,and the seamless steel pipe is sawed by the wheel saw method to facilitate the detection of the pipe section.The wall thickness parameters at the intersection of the circumference and the longitudinal plane lines are measured by the micrometer.The results show that the wall thickness of the seamless steel pipe is eccentric in cross section and spirally distorted in length direction,resulting in uneven wall thickness.The wall eccentricity of seamless steel pipe is affected by the wall thickness and thermal eccentricity obviously,and the roller speed and shoulder height will cause the negative change of wall eccentricity.The research is helpful to improve the control precision of rolling equipment and lay a certain foundation for the subsequent process optimization.
