In a traditional rolling mill rolling is done in several passes, but in tandem mill there are several stands (>=2 stands) and reductions take place successively. The number of stands ranges from 2 to 18. Tandem mills can be either of hot or cold rolling mill types. Cold rolling mills may be further divided into continuous or batch processing.
The heart of the temper mill is the cold rolling mill stand which produces the temper pass. It will include electric powered drive motors and speed reduction gearing suited to the process desired. The design of the rolling mill can be a 2-high or 4-high (even 6-high in some cases). The mill stand can be work roll driven or back up roll driven.

Thin strip casting [3] with a thickness of 2 mm has bypassed the tandem hot mill; and further reduction in the casting thickness to produce strip steel the same as annealed cold rolled strip will bypass the tandem cold mill and the annealing process. The need for tandem rolling mills, and rolling mills in general, is being [when?] reduced by ...
The manufacturing process involves forming the material by either press-braking or cold roll forming to achieve the desired shape. When steel is formed by press-braking or cold rolled forming, there is a change in the mechanical properties of the material by virtue of the cold working of the metal.
Schematic of a Sendzimir Mill. The Z-Mill or Sendzimir Mill is a machine for rolling steels. [1] [2] Unlike a traditional rolling mill this 20-high cluster mill configuration utilizes cascaded supporting rolls to apply force on the small work rolls in the center. This allows the application of a higher roll pressure without bending the work ...
SSP specializes in the production of cold rolled stainless steel in the form of coils and sheets. [3] The raw materials are imported and also supplied by Alloy Steel Plant in Durgapur. [2] The steel melting shop's annual capacity is 1,80,000 tonnes of slabs per annum. The hot-rolling mill and cold-rolling mill have capacities of 3,64,000 and ...
Coils and strips of strip steel. Strip steel [1] [2] or cold rolled strip is a steel product that is produced from a hot rolled strip that has been pickled.The coil is then reduced by a single stand cold roll steel mill straight away or reversing mill or in a tandem mill consisting of several single stands in a series.
