[0001] The present invention belongs to the technical field of iron and steel metallurgy automation, and more specifically, relates to a hot casting billet width remote query system and method. Background Art

[0002] Silicon steel has the characteristics of low high temperature strength and large solidification shrinkage. Under the pressure of the casting machine and the static pressure of the molten steel, silicon steel billets are prone to deformation during the casting process, and the width control deviation is large, which is very likely to cause width deviation, affecting subsequent hot rolling production. Therefore, timely discovering abnormal width of hot billets in the continuous casting process, removing abnormal billets from the production line, and adjusting the continuous casting process parameters can effectively improve the billet width quality and heat delivery rate.

[0003] At present, most of the existing billet width measurement systems adopt hardware configuration + host computer mode, which can read and write different types of PLCs, instruments, intelligent modules and boards, collect industrial site signals, and present industrial site information in an intuitive and vivid way, so as to monitor the industrial site. It has the advantages of powerful functions, good scalability, reliability and high development efficiency. However, such systems do not have the function of multi-terminal remote simultaneous access, and data can only be provided in the form of reports, or exported to external databases through ODBC for other business systems to call. In the continuous casting production process, multiple process departments such as casting production operators, process technicians, finishing hot delivery personnel, etc. need to monitor the actual width data of the billet in real time. The existing width measurement system can no longer meet the needs of multi-terminal remote access. It is urgent to develop a remote query system for the width of hot billets.
