Hydraulic gap controls, with mill steer and roll eccentricity compensation. ... Linked to phase transformation when exiting the hot rolling mill along the run out table, the coiling step and at the coil yard level, the choice of finishing mill temperature, coiling temperature and temperature–time paths have a major influence on achieving ...
In this study, a new diagnosis method for roll eccentricity under the roll speed changes was developed. The new method was induced from analyzing the rolling mechanism by using rolling force models, radiusspeed relationship, and measured rolling force, etc. Simulation results by using the field data show that the proposed method is very useful.
rolling phases will be initiated automatically on the basis of the latest coil, roll and adaptation data as well as the operator trimming values and a product dependent rolling specification. Adaptive models for roll force, torque, forward slip, roll and strip temperature, thermal crown, mill stand module, roll bending and wear are used to predict
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semifinished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.

ARTICS Hot Rolling Mills Real time control for Hot Rolling Mills. With more than 50 years of experience, Nidec Industrial Solutions has developed a vast array of functions based on autoadaptive mathematical models that optimize rolling schedule calculations in real time.
LQG Regulation: Rolling Mill Case Study Overview of this Case Study. This case study demonstrates the use of the LQG design tools in a process control application. The goal is to regulate the horizontal and vertical thickness of the beam produced by a hot steel rolling mill.
Roll eccentricity is a periodic disturbance caused by a structure of back up rolls in rolling mills, and it affects product thickness accuracy. It cannot be measured directly by sensors, so it should be identified by measured thickness or measured roll force.
A rolling mill for rolling strip in which one of its rolls serves both as a mill roll and as a gauge and/or profile measuring roll. The one roll has an outer sleeve for deflection under the rolling force and an internal stationary member for carrying a number of axially supported sensors for measuring the deflection of the sleeve and the rolling force to which the sleeve is subject, and ...
The hot metal is passed between two rolls to flatten it, lengthen it, reduce the crosssectional area and obtain a uniform thickness. Hotrolled steel is the most common product of the hot rolling process, and is widely used in the metal industry either as an end product or .
An indepth review of the roll eccentricity control design problem is provided which encompasses a number of recent, novel, design contributions and includes experimental results from two separate steel, tandem cold rolling mill installations.
