Method for automatically tracking quality of single continuous casting blank

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.

Description

technical field [0001] 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. Background technique [0002] At present, the billet continuous casting billet in each steelmaking plant adopts the method of spraying numbers on the whole furnace. The quality tracking of the billet can only be based on the furnace number, and it is impossible to accurately track a single billet. Defect process quality diagnosis, online quality prediction, batch and process quality evaluation, online quality early warning, online quality judgment, process quality service, etc. provide basic data support. Contents of the invention [0003] The purpose of the present invention is to provide a method for automatically tracking the quality of a single continuous casting slab, which dynamically tracks each strand of slab through model calculation, realizes accurate tracking of the quality infor...
