TANDEM COLD MILL Tandem cold-mill solutions from Primetals Technologies stand for high product yields combined with flexible production low operational costs and simplified maintenance work. Depending on the product mix the production capacity of continuous tandem mills from Primetals Technologies can exceed 1.2 million tons per year.

In this paper a chatter simulation model for the tandem cold rolling mills based on the well-known Coulomb and the Tresca friction models is proposed. By considering the

While operating tandem cold rolling mills it is observed that the products to be rolled and surface conditions of the rolls vary continuously. One has to efficiently calculate and control the various process variables of a tandem cold rolling mill to maintain high levels of product quality and productivity and to minimize the overall rolling cost.

The results show that the quantum chaos multi-objective evolutionary algorithm has the more powerful capability. The new proposed algorithm is applied to the load distribution optimization of tandem cold mill and the two-objective function modal is built based on the minimum energy consumption and rolling force equilibrium.

Mill chatter in tandem cold rolling mill is a major rejection to the quality and production of the strips. In most mill vibration models either the roll mass is usually limited to vibrate in vertical direction and vertical-horizontal directions or the multiple rolls system is simplified to a single mass system. However the torsional chatter is also a typical type of mill chatter and the

A tandem cold rolling mill usually consists of three to five stands of rollers each of which reduces the strip thickness by about 20 to 40 so that the total reduction in one pass may be by a factor ten. It has long been recognized that some if not most of the variations in thickness of strip produced by a cold-reduction mill have their
