三辊轧管机轧制的钢管表面裂纹缺陷控制

Analysis of Surface Crack of Steel Pipe Rolled by 3-h Pipe Mill

分析三辊轧管机轧管过程中变形量和回转角等因素对钢管表面质量的影响,指出变形参数的不合理对钢管表面有严重影响,并提出控制办法。

The influencing factors on steel pipe surface quality are analyzed, such as deformation amount, rotary angle, etc. It points out that the unreasonable deformation parameters have severe effects on steel pipe surface quality. At last, it puts forward some measures to control the deformation.
