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...

deep rolling is a kind of mechanical surface treatments that can improve surface quality, dimensional accuracy and mechanical properties of the parts. compressive residual stresses generated by the process reduce the tensile stresses during loading into the workpiece. the distribution of residual stress induced by deep rolling can be influenced by rolling parameters; such as overlap of the roll...

Cold rolling of steel is one of the most important metal forming processes so an accurate control of its parameters during the process is necessary. In this paper, the friction coefficient has been proposed as a function of cold rolling parameters such as forward slip, forward and backward tensile stresses ,strip thickness, static deformation, resistance of strip before and after rolling ,strip...

In the present study, the presence of brass mesh on the bond strength of aluminum (AA1050) strips in the cold roll bonding process was investigated. The influence of various process parameters including reduction in thickness, pre-rolling annealing, initial thickness of the strips, and post-rolling annealing was also considered. After cold roll bonding process, peeling test was carried out and ...

The most important purpose of cold rolling processes, in addition to obtaining appropriate mechanical features, is to achieve very low and more precise thicknesses’, the issue that is not possible in hot rolling processes. Today, most cold rolling lines designed continuously and usually consist of 4 to 6 fourroller rolling rack. Finished surface of obtained sheets of cold rolling is Harder and ...

Rolling allows leukocytes to maintain adhesion to vascular endothelium and to molecularly coated surfaces in flow chambers. Using insights from adhesive dynamics, a computational method for simulating leukocyte rolling and firm adhesion, we have developed a semianalytic model for the steady-state rolling of a leukocyte. After formation in a force-free region of the contact zone, receptor-ligand...

Layered alloys and composite materials have become an increasingly popular in industrial development. The roll bonding (RB) process, as a solid phase method of bonding, has been widely used in manufacturing large layered strips. In this study, aluminum alloy (AA 5083) strips were roll bonded at warm and cold temperatures. The effects of the rolling parameters such as the amount of plastic deform...

Ring rolling is a complicated process, in which rolling parameters influence directly the quality of ring. It is a process method with high productivity and few waste of material, widely used in transportation industry including automotive, shipbuilding, aerospace etc. During the rolling process of large-sized parts, crinkle and hollows often appear on surface, due to inconsistence of rolling m...
