1.1 Intelligent Systems in Cold Rolling Mill Nowadays, Neural Networks (NN) was used to improve the optimization of parameters in open loop controls in rolling mills[2]. As well as prediction of features like Flow stress, yield stress, the rolling force and rolling torque[4, 1, 11, 6, 12]. Evolutionary computing techniques show significant mod ...
Hot and cold metalworking between two or more rolls has been in existence since long before the industrial revolution. As a matter of fact, Leonardo da Vinci was credited for the metalworking mill prior to his death in 1519. When most people think of a rolling mill, they visualize sizable machinery in ferrous (iron, carbon steel

Multi-roll cold mill stands are described using different terms depending on their type and manufacturer: 12 and 20 roll stand Z-High® S-High. Multi-roll cold rolling mills are used to process high grade steel strip and non-ferrous metal strip. In order to prevent whipping of the work rolls, they are supported by means of intermediate
corporation production mill. The computer simulation have been used to study chatters and showed the variation of natural frequency with variety of factors viz. friction, rolling speed, tension, reduction and strip width. The stability criterion for rolling mill was derived analytically using the factors causing negative and positive damping [8].
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 the coil. Unique Features

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 (pay-off ree l), an entry winding machine (tension reel) and a delivery-winding machine (tension reel).
Cold-rolled steel sheets are produced by cold rolling from hot-rolled coil, the typical manufacturing processes are described as Fig1. Pickling and Cold CSVC produces its cold rolled products by the combination line of PLTCM (abbreviated from Pickling and Tandem Cold-rolling Mill), and CAL (abbreviated from Continuous Annealing Line) respectively.

Rolling process breaks and offsets the lattice planes of the material and increases the dislocation number, which results in material to resist the deformation and making it harder and stronger. Rolled material shows an elongated grain structure (Figure 1). 2. Types of Cold Rolling Mill Strip rolling can be done with different type of mills
