The looper control of hot strip finishing mill is one of the most critical control items in hot strip rolling mill process. It is a highly complex nonlinear system, with strong states coupling and uncertainty that present a difficult control challenge. Loopers are placed between finishing mill stands not only to control the mass flow of the two stands but also to generate a constant specific ...

Rolling of soft metals like gold, silver and perhaps lead was first performed by goldsmiths for making jewelry. Hand driven rolls of about ½ inches ( mm) in diameter were in use during the fourteenth century. However, the concept of a true rolling mill is first found as a sketch in the notebook of Leonardo da Vinci.

The cold rolling of metal strip is one process in which a sequence of processes is performed to convert the raw materials into a finished product. It is a deformation process in which the thickness of the strip is reduced by compressive forces exerted by two opposing rolls (normally in a fourhigh arrangement).

Rolling is the process of plastically deforming metal by passing it between the roles. The rolling process is basically used for reducing the crosssectional area of the metal stock. (The width is the same but there is a significant reduction of thickness). It is the most widely used forming process and it provides high production with very ...

Rolling is most often, (particularly in the case of the conversion of an ingot or continuous casting), performed hot. At a rolling mill, blooms and slabs are further rolled down to intermediate parts such as plate, sheet, strip, coil, billets, bars and rods. Many of these products will be the starting material for subsequent manufacturing ...
