The ladle metallurgical industry high temperature container , the enormous impact of its useful life and the safety of the use of the normal operation of the production of iron and steel enterprises . How to realize on -line monitoring of the ladle lining thickness , and issues of common concern for the majority of scientists . Firstly, according to a steel ladle structure and the materials used , including steel hull and steel structure ladle three - dimensional heat transfer model . CFD software corresponding to different working layer thickness , ladle lining , the temperature field of steel structures , analysis of the impact of the external surface temperature of the working layer thickness changes . The calculation results show that : the the ladle outer surface temperature and the thickness of the working layer exists between the corresponding relationship with the prolonged use of ladle , the continuous thinned in the thickness of the working layer , the outer surface temperature is gradually increased . Then , to track the the ladle actual working conditions , on-site measurement of the temperature of the outer surface of the ladle and overhaul ladle layer thickness . Measurement results and calculation results are consistent , which indicates that the mathematical model and method is correct . Finally, the combination of the ladle surface temperature and the residual thickness of the actual measurement results , the steel package between the outer surface temperature and the residual thickness of the corresponding relations and error distribution law , using partition amend the method , the numerical simulation results carried out the error correction , and the establishment of correspondence between database the ladle the outer surface of each point temperature and lined with residual thickness , laid the foundation for the use of infrared cameras monitoring ladle lining damage .
