Problems solved by technology

[0003] In the actual production process, the steel strip is extremely prone to deviation after entering the annealing furnace, and then scratches the unit equipment in the annealing furnace
Once the deviation of the strip occurs in the annealing furnace, due to the scraping effect of the strip, the light one will cause the annealing furnace to be shut down for a long time (generally takes 5 hours to process), and the severe one will cause the cracking of the furnace wall in the annealing furnace. Furnace cover accident (generally takes 24 hours to deal with), which seriously affects the production efficiency of strip steel

Abstract

The invention relates to the technical field of iron and steel production, in particular to a method and device for controlling a deviation correction roller. The method for controlling the deviation correcting rollers includes: judging whether the steel strip entering the annealing furnace deviates; when the deviation of the strip occurs, analyzing the deviation of the strip; The operation parameters of the deviation correction roller are set, so that the deviation correction roller operates with the operation parameters, and the position correction of the strip is realized. The invention can effectively prevent the deviation phenomenon of the strip steel in the annealing furnace, and greatly improve the production efficiency of the strip steel.

Description

technical field [0001] The invention relates to the technical field of iron and steel production, in particular to a method and device for controlling a deviation correction roller. Background technique [0002] In the production process of strip steel, it is necessary to use an annealing furnace to heat-treat the strip steel to soften the strip steel so as to reduce the hardness of the strip steel and improve the plasticity and toughness of the strip steel. [0003] In the actual production process, the steel strip is extremely prone to deviation after entering the annealing furnace, and then scratches the unit equipment in the annealing furnace. Once the deviation of the strip occurs in the annealing furnace, due to the scraping effect of the strip, the light one will cause the annealing furnace to be shut down for a long time (generally takes 5 hours to process), and the severe one will cause the cracking of the furnace wall in the annealing furnace. Furnace cover accide...
