Abstract: Recently, the accuracy of hot strip gauge is strictly demanded, and the strip thickness becomes the most important quality in hot strip rolling. In order to improve the quality of the hot strip gage and to reduce the strip thickness deviation, the automatic gauge control (AGC) system now is widely used in modern hot strip mills.
AGC 4hi rolling mill control accuracy, especially suitable for high precision coldrolled strip production. Production line process Front coiler→(Unloading car)→Machine front device→ 4hi main rolling mil→ Machine after the device→After the coiler (Unloading car)→according demands to arrange the uncoiler, Starting straightening ...
Looper and tension control, shown in Fig. 2, is important in hot strip mills because they affect both the dimensional quality and the mass flow of a high strip tension between stands induces width shrinkage, thickness reduction and moreover can produce an edge wave on a strip.
The application at each roll mill required a set of two LSV''s, one located on either side of the mill. The combination measures strip entry and exit speed for determining elongation or for mass flow calculations. One of the 4High rolling mills is a reversing mill so the strip could be moving in either direction.
Improvement and application of Automatic Gauge Control system in hot strip rolling mills Abstract: Mill Modulus Control (MMC) is one of important methods on Automatic Gauge Control (AGC) systems of strip rolling mills. It would result in a slower adjusting speed of strip rolling gap to combine the former AGC system and MMC simply without ...
In the research area Hot Strip Rolling, advanced nonlinear process control problems associated with the operation of a tandem hotstrip finishing mill are solved. A tandem hotstrip mill like the one shown in Fig. 2 is a nonlinear MIMO dynamical system.
P. Kucsera et al. Hot Rolling Mill HGC Thickness Control Improvement – 98 – Another way to determine the thermal expansion of the work roll is the modelling of the heat transfer between the work rolls and the strip. This depends on the roll speed, strip thickness, the properties of the strip, roll gap, contact time and cooling parameters.
nology for hot strip rolling mills based on distributed agents is presented aimed to the diagnosis of hot strip rolling mills with controllers. In the operation of hot strip mills, human operators try to maintain rolling conditions in an appropriate situation. To help the operators, it is needed to build an in
been developed for hot or cold mill processes. The British Iron and SteelResearch Association (B1SRA) AGC method based on the gaug meter principle and the feede forward AGC method using the delivery time of the strip have been widely utilized in steel rolling mills [3]. Strip products thickness precision is an important quality parameter.

Infrared sensors measure strip and sheet temperature so that rolling mill stands can be efficiently set to match the steel''s temperature. Sensors can be used to detect the presence of hot metal and accurately time the roll stand operation. Pyrometers can be used to measure the roll temperature as water cools the roll during the quenching process.
For hot strip mill Edger applications, Xtek developed another special steel grade with superior resistance to the thermal fatigue and firecracking so prevalent with other rolls in this environment. Plate Leveling Rolls round out the Xtek''s roll product offerings with a special heat treatment providing more consistent depth of hardness ...
SMS DEMAG Hot Strip Mills 10 The drumtype shear installed between the roughing and finishing mills of a hot strip mill crops the transfer bar at its head and tail. In special applications, the drumtype shear also serves to divide transfer bars and finished plates. Based on the experience gained from more than 60 drumtype shears built so far,
