Embodiment Construction

[0025] The present invention will be further described below through embodiment.

[0026] A method for automatically tracking the quality of a single continuous casting slab. Its special features are: converter process and refining process, data collection is realized in the unit of furnace number; continuous casting process, data collection is realized in the unit of each continuous casting slab, By collecting the spraying time of the billet automatic number spraying machine, based on the constant casting speed of the casting machine, combined with the sizing information and the running speed of the billet roller table, the liquid level fluctuation and casting speed of the cast billet in the crystallizer are realized. And the automatic tracking of the corresponding tundish temperature realizes the traceability of the production process of a single billet.

[0027] The concrete implementation process of this embodiment:

[0028] Using automatic PLC control technology, databas...

Abstract

The invention relates to a method for automatically tracking the quality of a single continuous casting slab, which belongs to the field of converter steelmaking. The technical solution is: by collecting the spraying time of the billet automatic number spraying machine, based on the constant casting speed of the casting machine, combined with the fixed length information and the running speed of the billet roller table, the liquid level of the cast billet in the crystallizer is realized. The automatic tracking of fluctuation, casting speed and corresponding tundish temperature realizes the traceability of the production process of a single billet. The beneficial effects of the present invention are: dynamic tracking of each strand of slab through model calculation, accurate tracking of quality information in the production process of slab, and further realization of quality control of the whole process of single slab production, and realization of process quality control of a single slab. Traceability provides basic data support for continuous casting slab defect process quality diagnosis, online quality prediction, batch and process quality evaluation, online quality early warning, online quality judgment, process quality service, etc. It is suitable for promotion and application in various iron and steel enterprises.
