[2019-10-28]

During the use of the ladle, it is necessary to perform a visual inspection for each use to observe situations such as the melting loss of each part, etc. The control points mainly include the cleaning of nozzle and the inspection of the inner lining during the shift change, the inspection of ladle shell condition during tapping process, the inspection and tracking of ladle shell temperature during refining process, and the inspection and tracking of ladle shell temperature during casting process.

If one of the following conditions appears, ladle must be repaired offline: the thickness of the working layer of the slag line and ladle wall refractories is less than 50mm, the thickness of the ladle bottom refractories material is less than 100mm, and the working layer is peeled off in large areas or abnormally broken in the local area; the purge plug and the nozzle wellblock's residual thickness is lower than the control line; the local temperature of the wall is too high during the casting process.
