改进斜轧管材延伸机的新途径

A New Approach to Improving Rotary Rolling Pipe Elongating Mill

针对现代常见斜轧管材延伸机的几何模型,运用4个数学方程组计算变形区轧辊与轧件接触点的纵、横向速度,定量分析了其各自的缺点。在此基础上,运用4个数学方程组进行优化计算,得到一个合理的、新的斜轧管材延伸机的几何模型,从而找到了改进斜轧管材延伸机的新途径。

Addressing the commonly-used several geometrical models for the rotary-rolling pipe elongating mill, four mathematic equation sets are used to conduct the calculation of the longitudinal and transversal velocities at the roll-material contacting points in the deformation zone, and quantitatively analyze the shortcomings of each model. Based on the analysis, the four equation set are again employed to make the calculation for optimization purpose, resulting in a new reasonable geometrical model for the rotary-rolling pipe elongator, and thus providing a new approach to improving thereof.
