再谈斜轧轧辊与轧件线接触的几何条件(上)——斜轧扩径机和斜轧减径机的几何模型

Discussion Second Time on Geometrical Conditions of Line Contact between Cross Rolling Roll and Rolled Piece(PartⅠ)——Geometrical Models of Cross Rolling Expanding Mill and Cross Rolling Reducing Mill

在研究斜轧过程的4个基本数学方程的基础上,进一步讨论了两个回转曲面线接触的几何条件,以及由此条件推导的已知其中一个曲面求解另一个回转曲面的数学方程;再运用所获得的数学方程,讨论了斜轧扩径机和斜轧减径机的几何模型,探讨实现斜轧减径过程的可能性。

Further discussed are the geometrical conditions of line contact between two surfaces of revolution on the basis of the study on four essential mathematical equations in the process of cross rolling, and also discussed are the mathematical equations derived from these conditions with which another surfaces of revolution can be solved when one surfaces of revolution is known. The geometrical models of cross rolling expanding mill and cross rolling reducing mill are studied using the derived mathematical equations so as to investigate the possibility of the realization of cross rolling reducing process.
