tandem rolling mill or continuous rolling mill: tandem rolling mill process. It is a modern rolling mills and the rolling is done by one pass. The rolling is done in several passes for traditional several stands and reduction that take place successive roll. The number of stands like as 2 to 18. Those are either hot or cold rolling mill types.
Electrical Drive Definition: The system which is used for controlling the motion of an electrical machine, such type of system is called an electrical other words, the drive which uses the electric motor is called electrical drive. The electrical drive uses any of the prime movers like diesel or a petrol engine, gas or steam turbines, steam engines, hydraulic motors and electrical ...
Block mills. Using a block mill, which drives multiple rolling mills and has been used on 100m/s class wire rod lines, as the bar steel finishing mill, will achieve speeds far beyond the finishing speed of about 20m/s that was the limit of conventional mills.

The load commutated inverter drives are used in medium p ower,highpower and very high power drives,and high speed drives such as compressors,ex tructers,induced and forced draft fans,blowers,conveyers,aircraft test facilities,steel rolling mills,large ship propulsion,main line traction,flywheel energy storage and so o n.
Save energy, improve control and reduce motor wear using AC drives, also known as variable speed drives (VSD), inverters, or variable frequency drives (VFD).
Roller mill is a form of compression mill that uses a single, double, or triple cylindrical heavy wheel mounted horizontally and rotated about their long axis either in opposing pairs or against flat plates, to crush or grind various materials.
Consider the continuous rolling mill depicted in Fig. Suppose that the motion of the adjustable roller has a damping coefficient b, and that the force exerted by the rolled material on the adjustable roller is proportional to the material''s change in thickness: F s = c(T − x).Suppose further that the DC motor has a torque constant K t and a back emf constant K e, and that the rackand ...
Block diagram representation of the basic mill unit. Thus, it has been shown that if the block diagrams of individual stands are linked together so as to create a block diagram of the entire finishing mill, there will be a seamless flow of disturbance variables between the stands, and no interstand disturbance signals will have to be supplied externally.
The experimental hot rolling Hille mill, presented in Fig 1, used to carry out multipass forwardforward or forward reverse rolling and also complex multipass rollingexperiments, has a threephase 20hp induction motor for main drive, reduction gears for roll speed adjustment (between 2~63 rpm from the fixed motor speed of 1500 rpm) andtwo rolls with a diameter of 139 mm.
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. Rolling mill arrangements commonly used in manufacturing industry today include the two high mill, the two high reversing mill, the three high mill, the four high mill, the cluster mill, and the tandem rolling mill .

Drive System • Drives are used to provide controlled motion to CNC elements • A drive system consists of amplifier circuits, drive motors, and ball leadscrews. • The MCU feeds the control signals (position and speed) of each axis to the amplifier circuits. • The control signals are augmented to actuate drive
7. Slip Ring Induction Motor. It has high starting torque and large overload capacity. The speed of slip ring induction motor can be changed up to 50% of its normal speed. Slip ring induction motor is used for those industrial drives which require high starting torque and speed control such as lifts, pumps, winding machines, presses, line shafts, elevators and compressors etc.

Anti Backlash for CNC: Ball Screws, Bearing Blocks, and Anti Backlash Nuts. Anti Backlash Ball Screwws. If you''re looking over this page, I''ll assume you wonder why you should eliminate backlash (or how much can your stand), you want to build a CNC machine from scratch, or you are converting a manual machine that has measurable backlash.
Vituvius described the new type of mill in documents made public between the years 20 to 11 This type of mill involved a vertical water wheel fastened to a horizontal drive shaft. To carry the power to the millstones, gears were used, changing the direction of the drive 90 degrees.
1971 as a mill equipped with a notwist block mill installed on each of four strands and a highly efficient mill capable of simultaneously rolling different qualities and sizes of steel materials. Recently, in 2008, a new intermediate rolling mill (prefinish block mill (PFB)) was introduced, and a significant improvement in the dimensional
