Based on the fact that some local tube makers are using stretch-reducing process and equipment inappropriately,the author points out that correct selection of stretch-reducing process technology has to be made and that none of the welded tubes stretch-reduced can be considered as seamless steel tube. Stringent criteria has been set up for all the aspects of the stretchreducing mill equipment from design to manufacture. Inappropriate equipment selection would hardly meet tube reducing purpose to turn...

Based on the fact that some local tube makers are using stretch-reducing process and equipment inappropriately,the author points out that correct selection of stretch-reducing process technology has to be made and that none of the welded tubes stretch-reduced can be considered as seamless steel tube. Stringent criteria has been set up for all the aspects of the stretchreducing mill equipment from design to manufacture. Inappropriate equipment selection would hardly meet tube reducing purpose to turn out qualified products.

针对国内一些地方企业应用张力减径工艺和设备存在的偏差,指出应正确选用张力减径工艺,不能把经过张力减径的焊管称为无缝钢管。张力减径设备从设计到制造都有严格的要求,若选用不当,则达不到减径功能,难以生产出合格的产品。

The iterative learning control is a high performance control technique for the systems or prcocesses of repetive operation,which produces a new input signal in response to the error signal between the actual outputs and desired outputs Based on the iterative learning control rule,the online learning algorithms for stretch reducing process of seamless pipe were proposed for average wall thickness control (WTCA),in which the measured wall thickness and specifications of the tubes are used to compensate...

The iterative learning control is a high performance control technique for the systems or prcocesses of repetive operation,which produces a new input signal in response to the error signal between the actual outputs and desired outputs Based on the iterative learning control rule,the online learning algorithms for stretch reducing process of seamless pipe were proposed for average wall thickness control (WTCA),in which the measured wall thickness and specifications of the tubes are used to compensate for the disturbance caused by the system uncertainty and the mathematical model error through adjusting rollers speed adaptively The results of simulation and experiments demonstrated the effectiveness of this new method
