controller from the 800xA Automation platform is outstandingly well suited to meet these requirements [1]. The complexity of the process and the corresponding requirements with respect to the control system are rising with the number of stands being involved. Tandem Cold Rolling Mills (TCM) with up to four or five stands
Automated realtime monitoring of production processes Almost all industrial applications have one thing in common: they have drives that power processes, move mass or convert energy. The same is true of the rolling mills at the aluminum rolling plant Aluminium Norf (Alunorf). The company
As regards "abnormal" rolling conditions which are more or less very "normal" for rolling mills roll damage often occurs with consequences for the mill and the rolled product. Evidently the reasons of roll
Factbox 1 ABB and rolling mills. Footnote. 1) A pass is one deformation step consisting of the different phases threading, rolling at constant speed, deceleration and tailout of the strip through the mill. A pass schedule is a series of values for the pass, such as thickness, speeds and forces presets.
Billets are produced through Induction Furnace, Ladle Refining Furnace and Continuous Casting Machine route. Raw materials of billet production are mild steel scrap, ferroalloys, directreduced iron, carburizers, decarburizers and fluxes additives. Bars are produced in fully automated ReRolling Mills.
Automatic Gauge Control (AGC) System. Waterbury Farrel Automatic Gauge Control (AGC) Systems ensure closetolerance strip at the push of a button. The system automatically maintains extremely tight gauge tolerances as the strip passes through the mill at up to 1,000 meters per minute. The Waterbury Farrel patented AGC monitors strip gauge...
Within foil rolling lines they are typically designed as roughing mills, intermediate mills and finishing mills. For each new strip rolling mill or those to be modernized, a holistic approach to perfectly synchronize mechanics, hydraulics, automation and drive technology in .
For almost forty years it has successfully designed, produced and commissioned industrial automation systems for the management of process automation in the iron and steel industry. This success is thanks to its deep expertise in various system typologies, including melt shops, continuous casters, long products rolling mills for bars, wire rods and sections, water treatment plants and dedusting systems.
Automation has proved to be the solution for most of these prerequisites for Cost optimisation necessary for the success of Small and Medium Capacity Rolling Mills. The Mills being designed and installed today are generally Straight Line Mills with a number of continuous .
An integrated plant for the production of elongated product of relatively small cross section, such as bars and rods, contains an automated system for the administration of rolling mill operation. The system provides for the standby storage of mill stands and bypass tables in proximity to the mill roll pass line.
In a modern steel plant, hotrolling is performed under computer control. The rolling process involves the forming of a large, hot metal billet by passing it through a rolling mill consisting of one or more sets of large cylindrical rolls that squeeze the metal and reduce its cross section. Several passes are required to reduce the ingot gradually to the desired thickness.
Bar automatic counting system as an important part in the bar rolling mill production it is the key technology to realize negative deviation rolling of bar production, delivery according to theoretical weight, and international market.
