In a metal rolling process, rolls, stands, bearings, housing, motors, and other mechanical equipment are all a necessary part of the manufacturing operation. The place where all the equipment for metal rolling manufacture is set up is called a rolling mill. Rolling mills often vary in the type, number, and position of rolls.
The roughing mill is made up of Multiple independent rolling mill stands, Billets heated in the furnace until they glow bright orange-yellow are rolled through one stand at a time to produce transfer bars suitable for finish rolling. High-pressure water-jet nozzles clean the oxidized iron, or scale, from the surface along the way.
In a single pass the hot rolling reduce the width of the material. We can see various types of strips and sheets in cold rolling process they are skin rolled, quarter hard, half hard, and full hard. By using the full hard rolling it reduce the thickness of material by 50 %. Skin rolling reduces the 0.5 to 1 % of the material during the process.

Most primary rolling is done in either a two high reversing mill or a three-high continuous rolling mill. Final products from hot rolling include plates, strips and a wide variety of bars and sections. Plates and strips are normally rolled between two plain cylindrical rolls, or on four-high mills. a. Two-High Reversing Mill:
Thread Rolling Figure 13.16 (a) Features of a machined or rolled thread. (b) Grain flow in machined and rolled threads. Unlike machining, which cuts through the grains of the metal, the rolling of threads causes improved strength, because of cold working and favorable grain flow.

The mill extant today dated from c. 1870 when it was rebuilt by the Villines family. A wooden, overshot water wheel was replaced by a metal turbine when the mill was converted to a roller mill grinding process. A single pair of millstones continued to be used to grind corn meal until the 1960s when the mill's history of community service ended.
John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 2.7 Generation III – Coil Box Hot Strip Mills. In the 1970s, Stelco of Canada developed the hot coil box designed for installation in hot strip mills ahead of the finish mill for coiling the transfer bar from the roughing mill and uncoiling it into the finishing mill. The coil box reduced the distance between the roughing mill ...
The topic of control and optimisation of the hot-steel rolling mill process is of interest for several industrial sectors and so far several efforts have been done towards its solution [-]. The article offers one of the most effective solutions to the non-linear optimal control problem of the hot-steel rolling mill system.

The entire set up is called a rolling mill stand. One or more number of rolling stands in combination with other necessary and related equipment to obtain finished rolled products from one or similar group of input materials is called a rolling mill or rolling plant. Rolling process can be classified based on various conditions/methods employed

What Is A Rolling Mill? In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.
