基于非线性斜轧变形区的顶头锥角计算方式

曼乃斯曼桶形轧辊设计简单,加工方便,但形成非线性的斜轧变形区,导致壁厚不均。采用带有非线性顶头锥角的顶头与桶形辊相配合可以获得线性的成壁变形区,从而大大提高壁厚精度。本文提出了适合于工程应用的这种顶头的顶头锥角简化计算公式。

A Calculating Method of Cone Angle of Plug for the Non-linear Deformation Zone of Skew-rolling

The Mannesmann barrel-shaped rolls can be designed arid processed easily, but it makes the non-linear deformation zone in skew-rolling and leads to the inhomogeneous wall thickness. Linear deformation zone of generating wall can be obtained by means of non-linear cone angle plug combined with the barrel-shaped rolls, so the wall accuracy can be increased greatly. This paper has presented a simplified calculating equation about this cone angle of plug that can be applied to engineering practice well.
