Abstract

The invention discloses a method for tracking strip steel in a coiling area of a hot continuous rolling production line. The method comprises the following steps: moving a steel coil number of the strip steel from a first storage area to a second storage area when detecting the strip steel at an inlet of a laminar flow cooling area; moving the steel coil number to a third storage area when detecting the strip steel in a coiling machine and not detecting the strip steel at the inlet or an outlet of the laminar flow cooling area; moving the steel coil number to a fourth storage area when not detecting the strip steel in the coiling machine and detecting the strip steel in a bundler; moving the steel coil number to a fifth storage area when not detecting the strip steel in the bundler and detecting the strip steel in a steel coil trolley; moving the steel coil number to a sixth storage area when not detecting the strip steel in the steel coil trolley and detecting the strip steel in a steel coil conveying trolley; moving the steel coil number to a seventh storage area when not detecting the strip steel in the steel coil conveying trolley and detecting the strip steel in a stepping beam, scheduling the steel coil number and carrying out spray printing of the steel coil number on the strip steel.

Description

technical field [0001] The present invention relates to strip tracking in the coiling area, and more particularly, to a method for tracking the strip in the coiling area of ​​a hot continuous rolling production line. Background technique [0002] In the hot rolling production process, the correct tracking of the strip is one of the necessary conditions for the smooth production. Only when the billet being rolled corresponds to the target strip correctly, can the rolling production line obtain the correct parameter information (such as the original size of the billet, strip width, strip thickness, strip steel quality, Next process information, etc.), so as to produce qualified products according to the requirements of users. If the real strip steel is inconsistent with the steel coil number, the strip steel produced cannot meet the needs of users, and even cause serious economic losses to users. At present, in the coiling area of ​​the hot rolling production line, due to th...
