DC Motors speed synchronization for rolling mills The project aims at designing a system which is capable of synchronizing the speed of the slave motor (motor-2) with the master motor (motor-1). This system finds very useful in paper mills, steel industries etc..,. The master motor speed can be set
The speed synchronization between different stands is very significant in rolling systems to avoid system breakdown, which is actual serious matter in rolling systems [10]. Commonly, the mass flow model is applied assuming that strip width is constant during the mill, it can be expressed anywhere as following: 𝐹 = ℎ (15)
Title: Dc Motors Speed Synchronization For Rolling Mills Author: war.uk--07-47-10 Subject: Dc Motors Speed Synchronization For Rolling Mills
Roll speed synchronization control (cf. Fig. 2) should ensure a uniform mass flow along the whole tandem rolling mill. If the strip exit velocity at a roll gap is equal to the strip entry velocity at the neighboring downstream roll gap, the unloaded length of the loop between the two mill stands is constant.

A typical one of conventional systems of the type as described above is illustrated in FIG. 1. Referring to FIG. 1, reference numeral 1 designates a rolling mill of a No. N stand, 2 another rolling mill of a No. N+1 stand, 3 a work or material to be rolled (this advances in a direction from the No. N to the No. N+1 stand), and 4 an electric motor for driving rolls of each of the rolling …
In textile mills many processes requires speed synchronization of more than one motor involved in the process. Rolling of cloths must be synchronized with the speed of weaving spindle to avoid damage and synchronization of motor speed is vital in conveyor belt driven by multiple motors.

Within foil rolling lines they are typically designed as roughing mills, intermediate mills and finishing mills. For each new strip rolling mill or those to be modernized, a holistic approach to perfectly synchronize mechanics, hydraulics, automation and drive technology in their complex interaction is applied.

The WN range is the base type for the FUHR profile rolling mills. The WN type profile rolling machines are always used when profile wires need to be produced economically and normal precision is sufficient. The mechanical concept of this machine type leads to compact dimensions so that machines with large roll diameters are also possible.
Rewinding (also called as Recoiling) and Trimming are important operations to be carried out after the Cold Rolling of coils. If the coil has to undergo processes such as Batch annealing, in which the Cold Rolled coil winding tension is not suitable and must be reduced, then the coil must be re-wound with lower tension in the Rewinding Line.

rolling mill, dedicated roll cooling systems are required to fulfill the required functions. Examples are suitable roll cooling and lubricationsystems to fully utilize the advantages of HSS rolls in hot strip mills, and selective roll cooling systems as a method to control the flatness of the strip in cold rolling mills.
Fig 2 Typical 4-high stands showing various details. Pre-stressed mill stand – In a conventional rolling mill, the roller separating force which arises when the work piece bar is passed through the rolls is transferred through the backup rolls and their bearings to the mill house. In a pre-stressed mill stand, the two backup rolls are connected to each other by an …
Synchronization helps in making different DG sets behave as a virtual single unit and eliminates subdivision of total load. It helps in transferring load from one unit to another as during service period, so that the unit requiring service can be easily shut off. ... The VFD panels are widely used in tube mills, paper mills, extruder plants ...

We consider synchronization and stability of two unbalanced rotors reversely and fast excited by induction motors fixed on an oscillating body. We explore the energy balance of the system and show how the energy is transferred between the rotors via the oscillating body allowing the implementation of the synchronization of the two rotors. An approximate analytical analysis, …
Tags Rolling, Rolling Mills; Types Of Rolling Mills. It has been suggested that Leonardo Da Vinci invented the first rolling mill, but what exactly is a rolling mill? Rolling mills are units in which a metal forming process takes place. During this process various metal materials get passed through a massive pair of rolls, or material handling equipment.
