Technical Field

The invention relates to the technical field of steel production, in particular to a method for controlling ultra-long collision avoidance of a double-high-line three-roller way.

Background

The three roller rows of the double-high-speed wire are very important, the double-high-speed wire can be changed from a single high-speed wire which is roughly rolled into a double high-speed wire which is medium-rolled, namely, because the three roller rows buffer and convert, the length of the billet on the three roller rows of the double high-speed wire is directly related to the shape of the roughly rolled material and the length of the billet per se;

because the prior art does not realize accurate measurement of the rough rolling discharge length and accurate stop position and stop time optimization of the matching length, the slight change of the billet length can cause the production rhythm and the frequent occurrence of abnormal production; when the billet is too long, the red steel on the three-roller line directly hits the middle joint of the blocking shears at the middle rolling inlet, so that the red steel after rough rolling is deformed, the red steel is bent, the three-roller line cannot normally carry out red steel turnover, three red steel on the three-roller line are simultaneously consumed, billet raw materials are greatly wasted, and the yield and the production benefit are reduced; therefore, the invention provides a method and a system for controlling the overlength collision avoidance of the dual-high-line-array three-roller bed, a storage medium and a computing device, so as to solve the defects in the prior art.
