This paper describes walking control suppressing the lateral unstable movement of the strip in a hot strip finishing mill. The conventional method for controlling walking is well known as "load difference method", in which the measured load difference between the drive and operator sides of the rolling stand is fed back to the roll gap slant reference.

Strip products thickness precision is an important quality parameter.

J.F. Cameron, C.G. Clayton, in Radioisotope Instruments, 1971 Cold-strip reduction mills. A tandem cold rolling mill usually consists of three to five stands of rollers, each of which reduces the strip thickness by about 20 to 40% so that the total reduction in one pass may be by a factor ten.. It has long been recognized that some, if not most, of the variations in thickness of strip produced ...

Summary. Hot strip rolling mills are characterised by a process which has many interactions, is distributed with dominant transport delays and has a lack of measurements due to the severe environment. There is ever increasing market demand for better product quality of the steel strip hence the requirement for higher performance controllers.

HOT STRIP MILL — HIGHEST PERFORMANCE FOR NEW AND EXISTING STEEL MILLS The demand for hot rolled strip is growing in multiple ways. To remain competitive, new and existing mills must meet this challenge in the best possible way. The production of hot strip is a …

The hot strip mill supplies coils for cold rolling mill, strip shearing and slitting units as well as a finished product for shipment directly to the customers. Most material is transported out of the mill area by an automated coil handling system to the storage aisle.

Camber and off-center in hot strip rolling process cause various problems including clogging, defects on the strip, and telpe phenomenon in a coil. To reduce camber and prevent off-center, we propose the integrated camber and steering control system based on adjusting roll gap level by previously designed mathematical model. By considering difficulties in the measurement and …

G. Engberg, L. Karlsson, in Fundamentals of Metallurgy, 2005 11.5.1 Hot rolling. Mill data from the hot strip mill has been used to calculate the mean flow stress in each pass, assuming the material to be elastic – ideally plastic. The roll force model used was a classical slab method with constant friction assumed in the roll gap. For the roughing mill (reversible 4-high) both roll force ...

Compact Strip Production (CSP), or in conventional hot-strip mills, has increased the requirements for precise mass-flow and thickness control. As an initial step to meet these demands, Primetals Technologies has developed a new control concept for rolling ultra-thin hot-rolled strip in the finishing mill of an ESP line.

of steel, it must be sent through a hot strip mill. In a hot strip mill, the slab width is reduced from 6-10 inches thickness into a strip anywhere from .06 to .5 inch thickness. This strip of steel is rolled into a large coil and shipped to customers or other steel processing plants within the company.

The control problem of the hot-steel rolling mill is thus formulated in two levels: (i) from to one computes the control inputs and that should be applied to the hot-steel roll mill system so as to assure that the angle of the looper and the tension on the strip will reach the desirable setpoints, (ii) the control inputs and become setpoints ...
