Newton's substitution method has been used to solve the equation. With known reduction between consecutive passes, geometrical dimension of square and diamond passes are computed. A model has been used to calculate pass design of a finishing train of a continuous billet mill producing 60 mm square billet from 120 mm square bloom.

Roll Pass Design. satyendra; June 18, 2014; 1 Comment ; Long products, roll grooves, Roll pass, Roll pass design, rolling mill, rolls, sections,; Roll Pass Design Long products are normally rolled in several passes, whose numbers are determined by the ratio of the initial input steel material (square or round billet or bloom) and final cross section of finished product.
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

"Rolling mill" redirects here. For mills that use rollers to crush grain or stone, see roller mill. Rolling visualization. (Click on image to view animation.) In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform.

pass sequence are important aspect to be assessed. The pre-diction 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 designed based on the type of
The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.

An overview of roll materials is given including adamites, high Cr materials, high speed tool steels and compound rolls. Non-uniform wear, recognised as the most detrimental phenomenon in section rolling, can be controlled by roll pass design. This can be achieved by computer-aided graphical and statistical analyses of various pass series.
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: Various rolling mill configurations are available to …
