mill is required. Pass Design The leader sections for the multiple slit rolling process, square, rectangular or round have to be of very close tolerance. This requires: * Correct pass profile in the rolls * Correct roll gap to ensure no overfill * Correct pass alignment between top and bottom rolls * Sound roll neck bearings and positive roll
flow. So, the design of the roll groove geometry and the roll pass sequence are important aspect to be assessed. The prediction of the load and torque with different groove designs plays an important role in order to improve the draft during rolling. The roll grooves in a roller and the roll pass sequence in a hot rolling mill are usually ...

Jun 18, 2014· Roll pass design is an essential part of long product rolling process, since the long products are rolled between the shaped rolls in the long product rolling mills. Roll pass design generally means the cutting of grooves in the roll body through which steel to be rolled is made to pass sequentially to get the desired contour and size.
Modern rolling practice can be attributed to the pioneering efforts of Henry Cort of Funtley Iron Mills, near Fareham, England. In 1783, a patent was issued to Henry Cort for his use of grooved rolls for rolling iron bars. With this new design, mills were able to produce 15 times more output per day than with a hammer. Although Cort was not the first to use grooved rolls, he was the first to ...

This book discusses as well the different types of rolls for various rolling mills, including blooming, plate, sheet, sheet bar, small section, heavy product, skin passing, and cold rolling mills. The final chapter explains the purpose of roll pass design to ensure the maximum output at minimum cost as well as to reduce the roll wear to a minimum.
An efficient roll pass design for angle iron Home Springer. The second roll pass variant is a copy of the 250 lightsection mill roll pass design at the Cherepovets Plant It differs from the former variant in that there was no aim to produce a symmetrical strip in the first special pass, by combining the geometric shapes of the passes in stands X and XI The incorrect distribution of .
The customer informed the need of a roll pass design using 150mm billet, which is the current size of the Melt Shop, besides not replacing the gearbox, which would represent an extra investment and demand a long implantation time. The mill''s staff reported not having historic of breaking this gearbox and no overload on the heavier products.

Roll pass design is a set of methods for determining the dimensions, shape, number, and type of arrangement of rolling mill passes. Development of a rational roll pass design for a rolling ...
There are enormous dimensional varieties of angles of the covered products, with linear mass from up to 60 kg / m. Depending on the angle dimensions and technical characteristics of the rolling mill, angles they could be rolled from two to eleven passes. There are at least four types of roll pass designs (currently used):
Mar 09, 2018· Watch how an optimum roll pass design leads to the distribution of loads across rolls, ensuring better rolling quality and reduction in specific power consumption. United Nations Development ...
Mar 27, 2003· Design the Layout and Roll Tooling. After completing the flower, you need to choose drive diameters and check for maximum flange roll sizes and possible interference with the rolling mill. During the design phase, you''ll need to consider increasing the pitch diameters of the rolls from pass to pass (also called stepup).
rolling. Shaping rolls are more complicated; and the work, usually starting as a square shape. Designing the sequence of intermediate shapes and corresponding rolls is called rollpass design. Its goal is to achieve uniform deformation throughout the cross section in each reduction. Fig. rolling mills:
on wear is another issue. Stresses from Hertzian pressure in 4high cold mill back up rolls were measured years ago, the results were never published, but of high interest also, maybe later. K. H.
