| Abstract: | Reducing tube through idle rolls is a new technology in seamless tube production. A continuous velocity field is established and applied to the tube due to draw-out by idle rolls,with an upper-bound analytical solution thus obtained. Compared with exerimental results,they are accord with each other. So the solution can be used to calculation of drawing force during draw-out by idle rolls. |
