4-high rolling mills used for reduction and skinpass at its Hagen, Germany, location. In this case, each mill uti-measurement. The application at each roll mill required a set of two LSVs, one located on either side of the mill. The combina-tion measures strip entry and exit speed for determining elongation or for mass flow calculations.
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.
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 4-High rolling mills is a reversing mill so the strip could be moving in either direction.
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 .
plate mill — power meets precision Quality plate is about metallurgical precision – high strength and toughness at alloying levels that keep costs down and preserve weldability. It is also about maintaining precise thickness across the full width, as well as consistent flatness to assure fit-up in fabrication.
maximum rolling speed of a cold or foil mill, 8 meters of strip is produced. It is easy to see why Automatic Gauge Control (AGC) is an essential component of modern rolling mills. Comprehensive AGC algorithms incorporate readings from dozens of sensors around the mill. Some of the key AGC input parameters are speed and tension. (See Figure 1)
2) Automatic control of hot strip rolling mill in thickness Automatic gauge control system is an automatic control of hot rolling mill in the most important part of. In the past, with the development of computer technology and the development of computer technology, it is widely used to control the thickness of strip by direct digital control
rolling mill, dedicated roll cooling systems are required to fulfill the required functions. Examples are suitable roll cooling and lubricationsystems to fully utilize the advantages of HSS rolls in hot strip mills, and selective roll cooling systems as a method to control the flatness of the strip in cold rolling mills.
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.
Mill control system and method for metal strip rolling con trolled in response to a sequence of controller scans are pro vided. A sensor suite is coupled to sense a plurality of param eters regarding the strip rolling. A model responsive to the sensed parameters is configured to estimate per scan at least
Application of Hot Rolling Lubrication on a Reversing Coil/Plate Mill Roll lubrication was introduced to the 4-high Steckel mill at Nucor Steel Tuscaloosa Inc. in 2011. It was found that the benefits included a significant extension to roll service life and notable reduction of mill torque. This paper will describe the mechanism of lubrication in
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. Mill modulus control (MMC) is one of important methods in AGC system for strip rolling mills.
Pilot hot rolling mill is developed with perfect measuring devices and automation system. The hot rolling experimental studies of the plate and strip can be done on this mill. Automation system for this pilot mill is composed with Basic Automation System (BAS), Process Control System (PCS) and Human Machine Interface system (HMI). PC server is used as the PCS hardware, and Microsoft software ...
