Roll pass design developed by analytical method was further optimised by FEM based model in a round bar rolling and in an ovalround roll pass and a combination of flat and round pass [19].
The selection of the rolling mill pass system is an important part of the rolling mill pass design. Whether it is appropriate to select have a decisive impact to the productivity and output of rolling mills, quality, consumption index, and production process operation, so the selection of rolling mill pass design system must be strictly carried out in accordance with specific conditions.
Determine the different elements of roll pass design according to power, torque and separating force calculations; Recognize the aspects of rounds and rod pass design amp; become acquainted with round rolling sequences; Apply several guiding and troubleshooting techniques in
Roll Pass Design is a complex problem due to the large number of processing conditions involved. Our purpose is to ensure the correct production of roll profiles within the constraints of the mill complying with quality standards, minimum cost and maximum output.
We can undertake technical evaluation of a rolling mill, its roll pass design and practices and can suggest means to improve rolling practices, roll pass design and mill management, to improve its marketing competitiveness by enhancing production, mill utilisation and yield of the rolled products, we can provide consultancy in following areas also: Selection of mill for particular Productmix.
#0183;#32;Thumb rules in rolls pass design Fittings from oval to round must be to For ovals width to height ratio must be less than 13. Spread When the steel is compressed in the rolls it will obviously move in the direction of least resistance, so usually there is not only longitudinal flow but also some lateral flow.
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

Modern rolling practice can be attributed to the pioneering efforts of Henry Cort of Funtley Iron Mills, near Fareham in Hampshire, 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

by design limits for maximum separation force, torque, Hertzian pressure etc, but these criteria are valid only under so called normal rolling conditions and even these change continuously with progressive wear in the contact zone. Besides normal rolling conditions a stable, theoretical assumption mills experience many different
A roll pass design for the sets of rolls of a nonmandrel type multiplestand pipe reducing mill, each set of rolls having three rolls. In order to improve the roll pass design so that the flow of material in the pipe is acted upon locally in such a way that the occurrence of local thickening of the pipe wall at critical points along the circumference of the pipe during reduction is decreased
