The online quality estimate system and method of the hot rolling coil in the high-temperature strip roller

摘要

The system which with the high-temperature strip roller estimates the quality of the hot rolling coil the online. As for the system, the chemical property which is obtained at steelmaking stage is captured, the device 5 which offers the data regarding rolling schedule is included. During hot rolling in order to measure process parameter, field device FD1 - FDn are provided in meter level. Obtaining the parameter data by the field device it supplies program possible logical control unit 1, to processor 2. The measurement data from the time domain the expedient 3 which is converted is provided to the spatial territory with segmented pursuit. Calculation module 4 extending to thickness at the same time, according to the length of the strip which is in the midst of rolling in order that it estimates mechanical quality, processes the data of the spatial territory which is converted. Display 6 indicates the quality which is estimated. In order in the future to use you can remember the data which is obtained, in data warehouse device 8. Collecting the appropriate characteristic where the device 7 which is provided in the system is estimated, it can supply to schedule compilation device 5.
