从原理、结构、使用等方面详细介绍了消除管尾三角的新方法，指出新方法的成功主要在于设置在支撑顶头和顶杆的支挡装置上的快速推进控制系统。当轧制临近管尾时，系统的压力传感器便发出信号，启动液压系统的换向阀，同时快推油缸快速向前推动，迅速穿透管坯，改变顶头相对于轧辊的位置，增大D／S值，从而消除管尾三角。工业性试验表明，这是一种简单而有效的消除管尾三角的方法。
From the aspects of principle, structure and application, a new method to eliminate the tail pipe trigonometry is introduced in detail. The success of the new method lies in the rapid propulsion control system installed on the support device supporting the head and the ejector rod. When the rolling near the tail, the system pressure sensor will send a signal to start the hydraulic system of the valve, while pushing the cylinder quickly push forward quickly penetrate the tube blank, changing the head relative to the roll position, increasing the D / S value, thereby eliminating the tube tail triangle. Industrial tests show that this is a simple and effective way to eliminate the tail triangle.
