In the metals industry, tandem hot strip rolling mills are used for rolling out thick semi nished products,, slabs, to thinner at products. The product, which is often referred to as strip, is clamped in each mill stand of the rolling mill train (cf. Fig. 1). As longitudinal tensile stresses in the strip have a .
ANDRITZ METALS supplies complete lines for the production and further processing of coldrolled strip from carbon steel, stainless steel and nonferrous metals, as well as industrial furnaces.

The tandem cold rolling mill of metal strip is a complex multivariable process whose control presents a significant engineering challenge. The present technology generally relies on a control structure where in the interactive coupling between process variables in partially reduced by several ...
Nov 09, 2016· 9 • Fourhigh or cluster mills are used. (Al, Cu alloys) • Cold rolling cannot reduce the thickness of a workpiece as much as hot rolling in a single pass. • This process increases strength upto 20% via strain hardening.
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semifinished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
the cold rolling mill In previous study of hot cold strip mill vibration we established a relations ship between mill chatter, mill speed and the phasing and number of teeth in the mill spindles. The specific problem studied was chatter occurring at finishing stand of strip mill, when is produced an accelerated roll wear on the bottom work
Cold Compact Mill (CCM) Pickled coils are rolled in twin stand cold rolling mill where they are processed into a specified thickness. Generally, the rolling reduction ratio is 50% to 90%. The critical point at this stage of the process is to maintain uniform and precise flatness throughout the entire length of .

Introduction Rolls are important consumption items in rolling mill, new purchased rolls are needed to confirm the quality to a certain level before it can be used on the rolling .
Thanks to its broad range of cold rolling mills for strip widths from 60 to 2,100 mm, ANDRITZ Metals has been one of the preferred cold rolling technology suppliers for decades. The supply focuses on 2high rolling mills, highcapacity 4high reduction rolling mills, and inline skin pass mill stands.
Rolling mill applications covered by ABB include: Single and multistand Mills Cluster and Sendzimir*) Mills Inline and continuous rolling mills Reversing and nonreversing Reduction, skinpass, double cold reduction (DCR) and foil rolling Steel, stainless, aluminium, copper and brass for .
Outline of reversing cold rolling mill and rolling method As illustrated in Figure 1, a reversing cold rolling mill is structured mainly of a mill proper, a winding machine (payoff ree l), an entry winding machine (tension reel) and a deliverywinding machine (tension reel).
Online Prediction Under Model Uncertainty via Dynamic Model Averaging: Application to a Cold Rolling Mill Adrian E. RAFTERY Department of Statistics University of Washington Seattle, WA (raftery) Miroslav KÁRNÝ Department of Adaptive Systems Institute of Information Theory and Automation (ÚTIA) Czech Academy of ...
The dynamic characteristics in a rolling process have been investigated with various methods, but a mathematical model to predict actual chatter vibration has not been established. In this paper, we propose a mathematical model of a cold rolling mill to predict chatter vibration.
