Innovative Measuring Technologies in Cold Rolling Mills ...
Figure 15: General Mill Layout (example Reversing Cold Mill) Shapemeter Rolls . Usually, during the cold rolling process, the strip is rolled under high tension. This high strip tension compensates for differences in length or shape defects so that the strip appears to be flat during the rolling operation. As soon as the strip is uncoiled latent shape defects will become visible. The ...
Cold Rolling | Nippon Yakin
Cold Rolling. In the cold rolling process, a hotrolled coil is made thinner by passing it between two rolls at room temperature. Not only is the thickness of the material made uniform, but the internal structure is made homogeneous at a microscopic level, and the surface of the roll is transferred to the material to provide a polished finish.

Cold Rolling of Steels – IspatGuru
· Cold rolling of pickled hot rolled strip is accomplished by processing steel strip through a rolling mill which has an entry end reel for uncoiling the pickled hot rolled coil and an exit end reel for coiling of the cold rolled strip. In between, there are one or more (normally up to 6 nos.) rolling mill stands for carrying out the cold reduction. Each mill stand has vertically stacked rolls ...

What is a Cold Roll?
· Compared with the hot roll, the cold roll only rolls the coldrolled piece, which is usually cast after smelting and often needs to be forged. With the development of casting technology, the cold roll is forged. It is being implemented continuously. The cold roll has a cold rolling work roll, an intermediate roll, and a support roll, the work roll is in direct contact with the rolling piece ...
Failure Analysis of Cold Mill Roll
· Reasons for Mill Roll Cracks. Owing to the high wear resistance and minimal plastic deformation of the cold mill roll, it is required that the surface of the cold mill roll have higher hardness and thicker hardening material of cold roll is 9Cr2Mo. The surface hardness of HS96 is obtained by surface quenching and tempering.

Cold Rolling
This mill is used to coldroll brass and copper into thin sheets. It is not possible to use flying micrometers for thickness measurement of this material because of the high degree of surface finish which is required and the malleable nature of the material. The mill produces brass strip up to 40 cm width and mm thickness at rolling speeds approaching 200 m/min. The thickness of brass on ...
