| Abstract Scope |
An auger flighting is a helical-shaped circular product to transfer bulk materials in broad applications. Continuous auger flightings are formed from straight steel strips by a specialty rolling mill. Because of the geometry and configuration of the auger flighting, the rolling is more complex than the ordinary longitudinal rolling while the publication describing the theoretical features of the auger flighting rolling was hardly seen. In this article, fundamental kinematics and mechanics of the auger flighting rolling are mathematically developed, from which the contact area, rolling force and torque are calculated and the affecting factors are evaluated. Slip characteristics between the strip and forming rolls and the effects of roll offset are studied. The design considerations, primarily of the main roll shafts and the required rolling mill power, are also given. The application results were compared to the actual rolling readings with satisfactory agreements. |
