| Abstract Scope |
The roundness and the angle of the edges on the cross-sectional profile at the exit of fin pass are crucial for the welding quality of the ERW tube. In this paper, the adjustment of the bending angles of break down rolls, the top and the side caging positions, and the fin pass gap were proposed to control the cross-sectional geometry and dimension accuracy of the roll formed blank at the exit of fin pass station. The roll forming machine layout is capable of making tube with diameter range from 5 to 13 inches. The CAE simulations were carried out to verify the proposed roll flower designs and the roll adjustment strategies. The CAE predictions showed the same flower design should have different roll adjustments for different tube size. The sound roll formed blank were obtained with proper roll adjustment and roll flower design. |
