摘　　要：针对唐钢高线吐丝机存在的吐丝质量问题,采用三次样条拟合现场实测数据得到吐丝管曲线方程;根据吐丝管中线材的速度和受力模型,分析线材在吐丝管中的运动状态,研究吐丝管空间曲线对吐丝质量的影响,得到吐丝管空间曲率波动过大和出口速度变化过快是导致吐丝质量不好的主要原因;通过改善吐丝管空间曲线和规范煨管工艺制度,显著改善了甩尾、吐圈摆动等吐丝质量,吐丝管寿命提高了1倍。For the working problems of laying head of high speed wire rod, choosing cubic spline function to fit the actual measurement data, the velocity and force model is used to analyze the state of the wire rod and research the curve＇ s effect on the laying head. On the basis of the consequence of calculation and the measured data, the bad working state is due to the sharply changed value of curvature of the pipe and the speed fast changing at the outlet of the pipe. By making some improvement on the space curve and bending processing of the pipe, the working state of laying head such as tail throwing is improved remarkably and the service life of single pipe doubles. The reform consequence approved that the theory model is correct and the renovation methods are reasonable.
