The roll profile of an angle bar is generally designed by the butterfly method however, the design of the roll profile of an irregular angle bar requires a special rule to take a tapered leg or a protrusion on the leg into account. For this purpose, the butterfly method has been modified in this study to design the roll profile for an irregular angle …
Groove angle for intermediate finish round pass should be 300 . Bottom radius for rounds is 1⁄2 of dia. Relief radius for rounds is 1/5th of bottom radius . Relief radius for rounds in …
Thus, this model may be considered validated. That is why we used it to model the new roll pass design [7]. The position of the rolls was chosen the same as that which was the best during the experimental rolling: vertical roll angle β = 3.5 ° the distance between the roll axes at the entry and exit is 698 and 695 mm, respec-tively.

The Roll Pass Engineer will provide support to both the Sales (pre-project) and Project Management (contract) teams by developing pass designs used to define/confirm equipment selections and process routes. These pass designs allow for the successful production of finished hot rolled sections in proposed, new or existing rolling mills.
roll groove depth, collar taper angle and corner radius. The simulations predicted the effective strain penetration, load, torque, fish tail billet end shapes, and metal flow behaviour at a chosen temperature, mill rpm and draft. ... Roll pass design developed by ana-lytical method was further optimised by FEM based model in a round bar ...
