摘　　要：介绍了连轧管机削尖轧制技术的原理、功能和技术特点,以及削尖轧制的控制方法和难点。着重介绍了削尖轧制技术在Φ159mm三辊式限动芯棒连轧管机上的开发和应用情况。应用结果表明,连轧管机采用削尖轧制技术能够明显减少钢管的切头尾长度,尤其是生产小直径钢管能提高钢管成材率1%～2%。Elaborated are the main aspects of the pipe-end sharpening technique, covering the principle, function, technical features, and the control method and the key issues related to the rolling process with the sharpening technique. Focused on are the development of the said technique with the Φ159 mm FQM, and application thereto. Relevant operation result shows that thanks to the said sharpening technique, the crop length of the pipe can be considerably reduced, particularly for small-sized pipe production, the yield can be increased by 1%~2%.
