Predictive Maintenance Steel Rolling Annealing Steel Mills not only have typical fans pumps compressors gearboxes and cooling towers but also have machines and processes unique to the steel industry The machine sizes machine designs operating speeds cycle times batch operations and harsh mill environments often command the use of carefully selected sensors and methods for effective equipment monitoring Iron making and steel making areas often have an abundance of large belt conveyors critical ultra low speed machines with limited rotation critical large EOT cranes and large volume turbo blowers coupled with 1260 ºC hot blast air molten liquid iron red hot slabs often carbon monoxide risks and of course rolling mills Sensor Selection IMI recognizes the varied needs and challenges of the steel industry and has successfully designed a wide variety of transducers and accessories to help meet the needs of their customers While most sensors can be used in a wide range of applications some sensors are better suited for the harsh conditions encountered in steel mill applications and have been pointed out in this section Cold Rolling Mills have similar operating and cyclic challenges as hot rolling but add in large numbers of roll chock bearings that are inherently difficult to instrument run at varying speeds loads in batch cycles These chocks are removed and reinstalled into the mill with new rolls many times a day after only minutes of operation at times Couple this with stringent product quality critical requirements and again many more extreme monitoring challenges are raised Precision ICP Accelerometer Model 626B01 n Low noise floor n Low frequency response to 12 cpm 0 2 Hz n Full sweep calibration See page 90 for more information Low Cost ICP Accelerometer Model 608A11 n Ideal for submersible applications n Small installation footprint n Stock integral cable lengths of 3 m 6 m 15 m See page 80 for more information 4 20 mA Output Sensor Model 640B01 n Available in top or side exit casings n Peak or RMS acceleration or velocity n Intrinsically safe explosion proof versions available See page 108 for more information Bearing Fault Detector Model 682B05 n Provides early warning of bearing and gear faults n Operates with PLC DCS SCADA alarm and control systems n Outputs 4 20 mA signals for peak acceleration and overall vibration See page 120 for more information IECEx IECEx IECEx IECEx IECEx IECEx IECEx IECEx IECEx IECEx IECEx IECEx Cold Rolling Areas Process Monitoring Protection IECEx IECEx IECEx IECEx 60 visit us online at www imi sensors com 1 716 684 0003
