Optimization of cold rolling process parameters in order .

many important rolling parameters. The associated static deflection model enables computation of the thickness profile and corresponding flatness of the rolled strip. Accurate methods of predicting the strip thickness profile and strip flatness are important in rolling mill design, rolling schedule set-up, control of mill flatness actuators, andTHE DEVELOPMENT OF THE THEORY OF METAL ROLLING AND ITS APPLICATION TO ROLLING MILL CONTROL INTRODUCTION In the realm of process control it is the rigidness of specifica- tion upon the finished product which dictates the refinement neces- sary for adequate control. As the end product becomes more and more critical the solution to the control problem can no longer be

Do you know all of the specific mill parameters that contribute to productivity, quality and yield at your long product rolling mill? How many automated control point solutions are leaving you with disconnected data, people and processes? Manual monitoring is unrealistic due to the large number of data sources and process variables.SKF online condition monitoring system increases reliability and reduces downtime at rolling mill. In addition to the harsh and dangerous manufacturing environment, there are process parameter changes between steel grades, variable and slow speed equipment, shock loads, frequent roll changes and resonance conditions leading to chatter marks on .

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.Jul 04, 2017 · Its test benches can be used to test run 90m-135m/s high-speed wire finish rolling mills and pre-finish rolling mills at varied speed with all the necessary parameters taken by sophisticated .

Model input parameters: Roll and spray bars Nozzle types and flow characteristics Valve characteristics Coolant type Strip and rolling Interface for Footprint roll cooling design model. Roll Cooling Design .May 30, 2013 · Some Basics of Rolling and Rolling Mills Rolling is the process of plastically deforming metal by passing it between rolls. It is the most widely used forming process, which provides high production and close control of final product.

Rolling processes 5-1 introduction: Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (5-1). Fig. (5-1) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.ROLLING The rolling mill is equipped with a walking beam furnace with a capacity of 125 tons per hour. Blooms are de-scaled after exiting the furnace, and then proceed through a five stand roughing mill, a six stand intermediate mill, and an eight stand finishing mill. Dimensional control

Aug 16, 2001 · Strip Rolling in the Breakdown Section. Sometimes, the breakdown section can be the site of problems with strip rolling from side to side, or rolling high on one side. Some possible causes include: Loose entry table. Uncentered strip entering the mill. Loose driven stands. Unparallel breakdown stands. Improper design for extremely light or .Mill stiffness is an important parameter for strip rolling mill, but it is difficult to online detect. When the wide of strip are changed, or the rollers are changed, the mill stiffness will change slightly. This change can affect the thickness precision and flatness precision significantly. Making full use of the massive process data, the mill stiffness.

Research area Hot Strip Rolling Modeling, Observer and Control Design of a Tandem Hot Strip Rolling Mill Research focus. Modeling and parameter identification for tandem hot strip rolling mills; Estimation of non-measurable system quantities; Model-based process control and optimization of nonlinear multi-input multi-output (MIMO) systemsstrongly depends on hot rolling parameters such as strain, strainrate, temperature,groovedesignandrollingsequence. It influences the metal deformation behaviour within the pass and mill load requirement apart from roll wear. The metal flow behaviour in a hot rolling process is a complex phenomenon, which is complicated due to tensorial stress
