the hot rolling mill is coiled for transport to the cold mill which might be on the same site or elsewhere. Cold mills, in a wide range of types and sizes are available; some are single stand, others 3 stand and some 5 stand (Figures and ). Cold rolling speeds vary but modern mills operate at exit speeds as high as 3000 m per
1 HOT ROLLING PRACTICE – An Attempted Recollection Saral Dutta. B. Tech. (Hons.), Executive Director, ISP RMD, SAIL (Retired) Rolling is a metal forming process in which metal stock is passed through a pair of rolls.
A fast, reliable, and accurate mathematical model is needed to predict the rolling force, torque and exit temperature in the rolling process. Function of Paper: To propose an adaptable neural network model for a rolling mill
The roll grinding process is a special form of external cylindrical grinding between centres; the only difference being that the rolls being machined have much larger dimensions than conventional workpieces. The rolls are subjected to continuous wear in both hot and cold rolling mills and must be replaced and reworked at regular intervals.

A brief history of metal rolling for sheet and plate products. On the first day of our Aluminium Rolling Technology Course I run a session entitled "Machinery and Process Overview". Part of this covers the history of metal rolling from the first known drawings of a mill to the stateoftheart rolling .
ROLLING MILLS. NTN's rollneck bearings feature a fourrow, taper setup that effectively supports both radial and axial loads. Most bearings are available with seals, and the bearing boxes can be designed in compact configurations since thrust bearings are eliminated.
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.
During the last 90 years, a lot of works have been published about rolling theories for the tworoll rolling process (2RP). In the last decades, the threeroll process (3RP) has become a significant technique in the production of wire rod and bars, as it allows to cover a wide range of finished dimensions with one pass design, or to realize very close tolerances, depending on the pass design ...
The Hot Strip Mill Model can be used for a variety of applications. Current users have utilized the HSMM to study mill configurations, rolling schedules, and process parameters to gain detailed insight into their operations not normally available with their current models and control systems (such as
Dec 08, 2013· Rolling conditions can be described only in general. In real practice these conditions are never stable. The conditions can change and frequently from good to worse within a rolling campaign. Some rolling mills face roll problems frequently though some very similar mills .
conventional nonendless type rolling mills are still used for thin strip rolling. In case fewer stands are used in the conventional nonendless type rolling mills to reduce the cost, the rolling speed is in general a little lower. In a compact hot strip mill, which is smaller than other conventional rolling mills, the rolling speed is also low.
In this paper, several issues of looper control in rolling mills are discussed and a fuzzy logic control is proposed to address the enumerated issues. The proposed system incorporated fast tuning algorithms for both offline and online learning of membership functions and singleton values. Also, it is relatively simple to design and implement.

ROLLING FLAT AND SHAPED WIRE The Manufacturing Process of Rolling – Basic Definitions Rolling is the technical process of transforming the cross section of a feed stock that passes through a set of rotationally symmetric tools called rolls. Besides shape, the rolling process also changes
XRoll® characterizes the family of brands from our Hot Rolling Mills division. It symbolizes plants and technical equipment for the economical and flexible production of hot strip and heavy plate. MODERN PRODUCTION PROCESSES Today, thermomechanical rolling is the most important production process for the manufacture of highstrength plates.
The mill line is the heart of the heavyplate rolling mill. With rolling forces of up to 120 Meganewton, we have supplied the most powerful heavyplate mill stands worldwide. Our CVC ® plus technology is ideal for efficient profile and flatness control as well as increased mill productivity.
Hot Rolling is done in the 2High Roll stands. Theory of Rolling Angle of Bite Top Roll Bottom Roll Input H0 Output H1 Theory of Rolling Angle of bite is 2530 Degrees in case of Continuos Mills and a max of 20 Degrees in case of Crosscountry Mills. The picture also indicates that the more the Roll Dia the more is the spread.
