Super-long collision avoidance control method for double-altitude three-row roller way

Abstract

The invention discloses a super-long collision avoidance control method for a double-altitude three-row roller way, and relates to the technical field of steel production. The method comprises the following steps: double-altitude three-row roller way rough rolling discharge length data and double-altitude standard billet three-row roller way rough rolling discharge length data are collected in real time, and a data transmission system is reconstructed; and a network quality inspection unit is additionally arranged in the data transmission system, the double-altitude three-row roller way rough rolling discharge length data received by the data transmission system is compared with the double-altitude standard steel billet three-row roller way rough rolling discharge length data, and the double-altitude three-roller-way delay stop correction time is adjusted according to the ratio. According to the method, the ultra-long collision avoidance of the double-altitude three-row roller way can be quickly, accurately and simply controlled in real time, and the adjustment precision of the double-altitude three-row roller way delay stop correction time is greatly improved through the control adjustment mode; and the accurate stop position and the accurate stop time of red steel materials on the three-row roller way after rough rolling of double-altitude billet with different lengths can be more accurately controlled.

Description

technical field [0001] The invention relates to the technical field of iron and steel production, in particular to a super-long collision avoidance control method with double-high lines and three-roller tables. Background technique [0002] The three-roller table of the double-high line is very important. The reason why the double-high line can be changed from a rough-rolled single-high line to a medium-rolled double-high line is because of the buffer and conversion of the three-roller table. The double-high line has three rolls. The length of the billet on the road is directly related to the shape of the rough rolled material, and is also related to the length of the billet itself; [0003] Since the existing technology does not realize the accurate measurement of the length of the rough rolling discharge and the precise stop position and stop time optimization of the matching length, the slight change in the length of the billet will lead to frequent production rhythm and ...

Problems solved by technology

[0003] Since the existing technology does not realize the accurate measurement of the length of the rough rolling discharge and the precise stop position and optimization of the stop time of the matching length, the slight change in the length of the billet will lead to frequent production rhythm and abnormal production; when the billet is too long It will cause the red steel on the third roller table to directly hit the middle joint of the cutting shear at the entrance of the middle rolling, and then deform the red steel material after rough rolling, which will cause the red steel material to bend, and then cause the third roller The road cannot normally carry out the turnover of red steel materials, which leads to the simultaneous lifting of three red steel materials on the third roller table, which greatly wastes the billet raw materials and reduces the yield and production efficiency; therefore, the present invention proposes a double-high line The ultra-long collision avoidance control method, system, storage medium and computing equipment of the third roller table to solve the deficiencies in the prior art
