無駆動垂直ロールを有する連続ビレット圧延機における圧延特性の解析

抄録

In order to put a new type of continuous billet mill with an arrangement of H-V stands where the vertical roll stands are drive-free to practical use, it is necessary to establish the method to estimate various rolling loads for mill design.
In this paper, the variations in rolling force at driven horizontal roll stands and non-driven vertical roll stands, rolling torque at driven roll stands and inter-stand tension or compression during hot rolling experiments through 5 stands continuous billet mill were measured. Furthermore, the rolling load at each roll stand, the rolling torque at the driven roll stand and the inter-stand compression on the process where materials are pushed into the non-driven vertical roll stand from the adjacent driven horizontal roll stand were measured, analyzed theoretically and compared with experimental results.
Calculated results of the rolling load at each roll stand, the rolling torque at the driven roll stand and the inter-stand compression generated between the driven horizontal roll stand and the non-driven vertical roll stand almost agreed with the experimental results. And the rolling loads can be estimated with practical accuracy.
