Rolling mills often vary in … Jan 14, 2013· WHERE IT IS DONE Rolling mill is a machine or a factory for shaping metal by passing it through rollers A rolling mill basically consists of • rolls • bearings • a housing for containing these parts • a drive (motor) for applying power to the rolls and controlling the speed
The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product. Nov 27, 2015· The final dimensional quality of the rolled product is determined by the rolling stands within the finishing mill. The dimensional accuracy in the final product depends on many factors including the initial stock dimensions, roll pass sequence, temperature, microstructure, roll surface quality, roll and stand stiffness and the stock/roll friction condition.
A BASIC UNDERSTANDING OF THE MECHANICS OF . After a roll change or a mill stop rolls need some time to return to stable thermal conditions, every new bar entering the mill creates an impact, and sometimes there are really severe rolling accidents, due to faults by operators, weak rolled materials with internal defects, or because Enfield Rolling Mills was in Millmarsh Lane, Brimsdown, Enfield, Middlesex on a 40-acre site set up in the early 1920s with a copper refinery (Enfield Copper Refinery), rod mill, wire mill, brass cake foundry, hot and cold rolling mills, 'Encon' continuous casting plant for bearing alloys, billet casting foundry and forge for high conductivity ...
Endless Hot Strip Rolling Process . In conventional hot strip production, slabs of thickness of about 250mm are heated in a furnace and are reduced to 30 to 60mm in thickness after passing through the roughing mill, and then further reducing it to within a range of 0.8 to 25.4mm by rolling in the finishing mill. Stanat Model TA-215 2-Hi/4-Hi rolling mill with reversing winders consisting of the following: The existing mill frame will be completely stripped and painted. All bearings and seals will be checked for wear and replaced as needed. A new mill drive with controls will be provided including a 5 HP inverter duty variable speed motor.
rolling mills can be achieved, then in some cases, cold rolling is not even required, which can result in a radical decrease of production costs.

A tandem mill is a special type of modern rolling mill where rolling is done in one pass. 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. Hot and Cold Rolling Explained To those on the outside, the rolling process is an unknown. The average person may be completely unaware of what rolling is, but it is something that is extremely important to know in the steel industry.
Various configurations of rolling mills: (d) cluster mill Cluster Mill 22 Variousconfigurations of rolling mills: (e) tandem rolling mill. Tandem Rolling Mill Rolling mills have several stages, where the each stage successively reduces the thickness of the stock until the desired cross section is achieved. Another control problem (besides the continuous caster) arising in the steel industry is the control of the exit steel thickness in a rolling mill. The diagram below shows the layout of a rolling mill, with thick steel going in one side, and thin steel coming out the other. Overview of the Example
