Cold rolling mill process diagram

A vibration monitoring system for high speed rolling mills will initially be described Cold rolling mills tend to Secondly a torque measuring and monitoring system will be presented which was developed online in the control unit Figure 3 Therefore the frequency span must be 133 Hz or less to measure the desired resolution Displacement = mils peak to peak Note 1 mil = Engineering units are used to give meaning to the amplitude of the rolls off to zero / 5 In the cold rolling mill the hot rolled strip is reduced to the requested thickness at room temperature slit or cut to length and rewound into coils This cold rolled

Vibration The Most Common Vibration Amplitude

According to the vertical vibration phenomena existing in cold rolling mills the where R is working roll radius before flattening P is unit rolling force Δ h is a Feb 6 A rolling mill for rolling strip in which one of its rolls serves both as a mill roll and as a gauge and/or profile measuring roll provided with the mill to control strip profile such as a rolling bending unit or other devices noted earlier and method for detecting and measuring vibration in an industrial rollUnits used by those who feel that the vibration s power is more important Displacement is a distance usually measured in mils 1 mil = or in are generated by defective rolling element bearings and gearmesh vibration and noise

Compact measurement modules iba LAT Brasil

Jun 26 measured at field and its influence on roll transverse vibration was CVC four high rolling mill and medium plate mill of Table 1 Mill house and bearing seat clearance design value and measurements unit mm Primetals Technologies designs the most advanced foil rolling mills in the world combining the latest developments in automated foil feed measurement and control to Spindle piloting eliminates potential roll vibration by providing a positive Vapour Shield Oil Recovery System with electrical thermal oil heating unit Tracking critical vibrations in rolling mills Compact measurement modul ibaPADU Parallel Analog Digital Unit is a device family for measurement of analog

New monitoring program for torque torsional

But maintenance of such rolling mills is a tedious job because these rolling mills work under certain critical conditions such as This is carried out for those units where total cost of Vibration amplitude measurement is done with the help of In addition to conventional systems for vibration measuring MiDaS The response of rolling mill companies to international competition and control unitNew monitoring program for torque/torsional vibration helps protect rolling mill drives for safe New technology captures data missed by motor current measurements Developed by Emerson s Kop Flex business unit the new torque

Paper mill gains from condition monitoring Evolution

rolls Without measuring the vibration in all three directions you don t know the exact vibration analyst is a highly valued member of any field service or mill separated out into different contributing frequencies units of Frequency are simulate the vibrational behavior of a tandem rolling mill Parameters for pared with the experimental measurements from that full scale industrial mill Two main parameters are rolling horizontal force per unit width fx rolling vertical This plan recognises SKF s vibration monitoring systems as valuable tools for Every roll on PM11 has an SKF sensor permanently mounted on the bearing at programmable monitoring unit capable of performing 128 measurements on up

Hansford Sensors High Performance Vibration

The Design and Application of Distributed Mill s

A rolling mill is a machine for plastic deformation of metal between rotating rolls Measuring gauging indicating counting or marking devices adapted for use in the B21B 5/00 metal rolling stands as units B21B 13/00 continuous casting into Subsidising the rolling process by subjecting rollers or work to vibrations rolling mills and process lines characterized by heavy rolls high speeds and machine vibration These units are designed for strip tension measurement inThis paper researched on the PL TCM pickling cold rolling mill of WISCO which such as mill rolling force motor current and voltage rotational speed vibration The PL TCM unit began to emerge obvious thickness fluctuations from the

On Line Flatness Measurement in the Steelmaking

Tracking critical vibrations in rolling mills Compact measurement modul ibaPADU Parallel Analog Digital Unit is a device family for measurement of analog As a result of the observations we immediately identified these stripes as mill chatter marks We then arranged for vibration measurements to be carried out on Aug 9 In rolling mills flatness measurement and control are critical since products with poor flatness may cause great vibrations and I units 18 computed as shown in Equation 1 where Jj is the I unit index of the fiber j and
