In the process of copper alloy hot continuous rolling, the problem of copper sticking to the roller seriously affects the surface quality, performance, and service life of the copper products. Roll sticking occurs as the adhesion energy of Cu is lower than that of Fe and the FeCu interface, and the severe surface deformation which forces the copper into direct contact with the roll during the ...

Steel wire is then produced from the coiled wire rod to a diameter typically less than inches ( mm). Unlike the hot roll process of wire rod, steel wire is produced using a drawing process, where the coiled wire rod's crosssection is reduced by pulling it through a single, or series of, drawing die (s). Drawing is usually performed ...

In some mills ( hot strip mill, wire rod mill, merchant mill, and cold rolling mill), the rolled product is coiled in a coiler or a wind up reel. Mostly, rolling is done at high temperature, called hot rolling, because of requirement of large deformations. Hot rolling results in residual stressfree product.

Fig. : Rolling mill control From the above curves, we could understand the control of rolling mill. The solid curve, called plastic curve, represents the variation of rolling load with rolled thickness. As thickness reduces, roll force increases. This was shown earlier. The solid line represents the elastic deformation of the roll.
