Description

Technical Field

[0001] The present invention relates to the technical field of steel production, and particularly to a system and method for safely crossing steel in a double-line under a fault condition. Background Art

[0002] When the high-speed wire needs to pass the steel on the splitting roller table from another line due to steel piling up on one line, or when single-line rolling is required for a long time due to power or gas limitation on one line, double-line crossing of steel is also needed. The previous method was to force the hot detection by pressing the "hot detection lamp button" on the main control console for a long time. However, this method has two major drawbacks. One is instability. When the lamp button fails, it will cause steel piling up. The other is that it may cause the loop at the line with steel piling up to delay in starting the loop, bringing potential safety hazards to dealing with steel piling up at the loop. Specifically, when the signal is unstable, it will directly cause the interruption of the rolled piece tracking signal, thus leading to steel piling up on the rolling line. Moreover, it is easy to cause flying steel at the outlet of the loop. Such flying steel faults are very harmful to the entire production line. They will not only increase the safety risks at the production site but also damage the mechanical and electrical equipment on site. The mis-starting of the crossover 1# loop will directly cause harm to the personnel who are dealing with scrap steel or under maintenance, which is very dangerous. All existing technologies will not only bring potential safety hazards but also cause equipment accidents, and at the same time affect the stability of production. Summary of the Invention

A preposed double-line cross-passing steel system is designed and added between the inlets of the double-line intermediate rolling and the outlets of the steel distributing roller table. Then, a postposed double-line cross-passing steel system is designed and added between the inlets of the 1# hot detector of the 2# flying shear of the double line and the outlets of the 13th stand of the double line.

The auxiliary warning system is the jumping display of targeted and time-sensitive important information and multi-dimensional early warning based on the signal induction of the man-machine interface design and the selection of big data conditions. The systematic design is the all-element design based on the entire cross steel-passing process, from equipment startup, equipment operation, production steel-passing, process control to abnormal regulation. The dynamic variable intelligent interlock means that various variables with large amplitude changes during the cross steel-passing process are dynamically interlocked based on safety considerations, thereby reducing the safety risks of relevant operators and maintenance personnel from the source of dynamic design.
