Continuous casting data space-time matching method based on heat tracking and casting flow tracking

Abstract

The invention provides a continuous casting data space-time matching method based on heat tracking and casting flow tracking, and belongs to the technical field of steelmaking continuous casting. Themethod comprises the following steps: recording furnace number, casting flow production process data, key production time and key production events in real time, calculating the casting flow length inreal time through encoding, performing furnace number division on a just cut casting blank by utilizing the casting flow length, cutting information and the like, endowing the casting blank with furnace number information and casting blank number information, calculating a time window of the casting blank in each continuous casting device according to the casting flow length, matching the production process data of the time window with the time direction of the casting blank, and finally carrying out space-time transformation to finish the matching of the production process data with the length direction of the casting blank. According to the method, matching of the continuous casting production process and the casting blank can be rapidly and accurately completed, and data support is provided for continuous casting blank quality prediction and continuous casting production optimization control.

Description

technical field [0001] The invention relates to the technical field of steelmaking and continuous casting, in particular to a time-space matching method for continuous casting data based on heat tracking and strand tracking. Background technique [0002] In all processes of the steel production process, continuous casting casts molten steel into billets with certain specifications, which plays a linking role in the entire production process. Therefore, the quality of continuous casting slabs indicates the level of metallurgy and is an important guarantee for subsequent production of qualified products. With the application of processes such as hot charging and hot delivery, continuous casting and rolling, modern steel mills pay more and more attention to the quality of billets, and it is more and more important to realize accurate quality management of billets. Realizing continuous casting tracking and matching production data with slab is a key step to realize slab quality...

Problems solved by technology

[0004] From the above analysis, it can be seen that the two methods of simply realizing the continuous casting process tracking and marking the slab event after simple tracking have certain guiding significance for the quality management of the continuous casting slab, but in the actual production process, the two methods Only a simple threshold value analysis can be performed on the quality of the slab, and only the influence of a single production process factor on the quality of the slab can be considered, and it cannot reflect the influence of coupling of multiple factors in the entire production process on the quality of the slab, so it is impossible to accurately analyze the slab.
