strip tearing during cold rolling process has always been considered among the main concerns for steel companies. several works have been done so far regarding the examination of the issue. in this paper, experimental data from cold rolling tandem mill is used for detecting strip tearing. sensors are placed across the cold rolling tandem mill. they receive information on parameters (such as ang...

cold rolling process of a major transformation in the form of sheet metal and a wide range of steel products are produced in this way. elastic deformation during cold rolling working rollers and the inevitable increase in the rolling force. in this study, the effect of elastic deformation during cold rolling mill rollers working on the reciprocating back and forth in tandem with the presence of...

Temper rolling or skin pass rolling is one of cold rolling processes composed of a horizontal pass cold rolling mill stand. In this process, the thick strip is subjected to very light reduction (0.5–4%) in thickness in the presence of high friction amplitudes. One of the basic parameters of strip rolling processes is temper rolling force. A new rolling force model has been proposed for temper r...

In this paper, an analytical model based on Modified Slab Method is presented for rolling of clad sheet or double-layers in which the two layers are bounded prior to rolling. This model considers the general case of asymmetrical rolling due to unequal &#10surface speed, different contact friction, roll diameters, flow stress, and thickness ratios of the two layers. Using this model, rolling par...

in this study, the effect of cold rolling process on the microstructure and texture evolution in 1wt. % si non-orientedelectrical steel was investigated. for this purpose, all samples were processed through single-stage hot rolling at1100 ° c and two-stage cold rolling (cross rolling and unidirectional rolling) with intermediate annealing at 650 °cfor 35 seconds. finally, all of them were fully...

There is a complicated relation between cold flat rolling parameters such as effective input parameters of cold rolling, output cold rolling force and exit thickness of strips. In many mathematical models, the effect of some cold rolling parameters has been ignored and the outputs have not a desirable accuracy. In the other hand, there is a special relation among input thickness of strips, the ...
