The primal target of the experiment is to make a roll pass design for hot flat rolling. Roll pass design methods includes determining the dimensions, shape, number and type of arrangement of rolling mill passes. Necessary calculations are done to determine rolling load, torque and power by using the data.
The pass design model was generated on the basis of above two models as well as the rule-based pass design algorithm. Mill optimization of pass schedule crown distribution, roll profile ...
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.

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 roll-pass design. Its goal is to achieve uniform deformation throughout the cross section in each reduction. Fig. 5.5 5.5 rolling mills:

An efficient roll pass design for angle iron - Home - Springer. The second roll pass variant is a copy of the 250 light-section 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 .
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 step-up).

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.
mill is required. Pass Design The leader sections for the multiple slit rolling pro-cess, e.g. 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
Nov 30, 2016· However, rolling mills are major resource consumers; thus, urgent rationalisation is required in the relevant industrial systems. Roll pass design (RPD) is a principal factor that determines process efficiency, product quality and resource consumption. Therefore, it is important to optimise RPD including the selection of roll materials.

There are enormous dimensional varieties of angles of the covered products, with linear mass from 0.6 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):

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 ...
