Oct 30, 2017· Metal strip thickness gauge with accuracy 0,001 mm for cold rolling mills (steel, lead, brass, aluminium, Titanium Zinc, Nickel, bimetal,...) with AGC outputs, thickness range 0 3,5 mm ...
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.
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.
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,
Research on application of Smith predictor to monitor AGC in hot strip rolling mills
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 ...
Typical processing strip thickness: 0,15 to 8 mm Typical coil weight: 5 to 15 Ton; Skin Pass Mills Four High unidirectional Skin Pass Mills. INCO manufacture either skin pass mills for Hot Rolled black material or for Cold Rolled or Galvanized material. Mills can be complete or be installed in continuous treatment line. Strip width up to 1800 mm.
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.
In the application of roll lubriing hot rolling mills, several concerns arise,, bite and roll slippage and effectiveness. This paper studies the mechanism of roll lubrication of the reversing hot rolling mill theoretically and investigates the effect of the roll lubrication on mill .
To integrate a new roll gap lubrication system into an existing hot strip mill is a challenge problem. A lubrication expert system was developed and embedded into finish rolling setup system. The reference value setup by expert system is downloaded to roll bite lubrication PLC via finish mill PLC to open oil spraying valve and regulate the oil concentration.
We provide comprehensive engineering solutions for various applications in Steel ( and Other Metals ) Hot Cold Rolling Mills and associated applications in the Steel and Metals Industries. The range of our expertise includes the successful commissioning of the following : • 2HI Skin Pass Mill • 4HI Cold Rolling Mill • 6HI Cold ...
PROFILE FLATNESS MEASUREMENT IN HOT AND COLD ROLLING MILLS Alec Shaw, Sales Marketing IMS Asia Introduction A summary of the available methods of gauging profile and flatness in modern Hot and Cold Strip and Plate Mills is presented in .
Rolling processes 51 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 (51). Fig. (51) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.

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.
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.
ColdRolling Mill Machine Sale. Main Applications: Steel Coil Aluminum Coil Copper Coil Your Application We also provide high precision cold rolling mill and hot rolling mill You Need Better ColdRolling Mill at Good Price. Due to government environmental protection and Deproductivity Action, a lot of good machines are stopped, we can find you second hand rolling mills with good condition and ...
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.
