Rolling Mills  Manufacturers, Traders, Suppliers

In rolling mills, metal is processed as a starting product (in the form of ingots, slabs, ingots and billets) by rolling into sheets, strips, tubes and rods. The end products are only so-called semi-finished products, which are therefore only finished from the point of view of the rolling mills. In subsequent processes they are further processed to the finished product. Je according to the state of the materials the rolling type is determined. In hot rolling, the metal is first heated until it reaches the recrystallisation temperature. This is the point at which the lattice of the metal structure becomes flexible and easily deformable. The recrystallisation temperature should not be confused with the temperature at which the metal liquefies. This temperature is already at 20 degrees Celsius for some metals.In contrast to hot rolling, cold rolling forms the metal below the recrystallisation temperature.The products produced are divided into two groups. A distinction is made between long products and wide flat products. Long products are much longer than they are wide and thick. Either wire rolling mills (for example, wires that are rolled onto coils), girder or section rolling mills (for example, rails for railways that are often over 100 meters long) or pipe mills (for example, metal pipes such as water pipes) manufacture such products.Broad-flat products, on the other hand, are significantly wider than they are. This type is divided into strip rolling mills and sheet rolling mills.
