Continuous rolling production line cold bed material tracking method, device and system and medium

Abstract

The invention discloses a continuous rolling production line cold bed material tracking method, device and system and a medium. When a cold bed is powered on, data states of grooves on racks of the cold bed are initialized, in each cycle of skirt board action, when steel is allocated to the cold bed during the current skirt board action, the state of the first groove on the corresponding rack of the cold bed is marked as a steel state; in each cycle of action of the movable rack, one-time or repeated shifting treatment is carried out on data states of the grooves on the racks, and in each timeof shifting treatment, the data state of the current groove is used as the data state of the later groove; the state of the first groove of the corresponding rack is marked as a steel-free state; andin each cycle of action of the movable rack, the frequency of shifting treatment on the data states of the grooves is equal to the frequency of reciprocating movement of the movable rack in each cycle of action of the movable rack. Steel on all racks of the cold bed can be positioned and tracked accurately, and therefore whether steel exits in each groove on the racks can be accurately judged.

Description

technical field [0001] The invention relates to the technical field of iron and steel manufacturing, in particular to a method, device, system and medium for tracking material in a cooling bed of a continuous rolling production line. Background technique [0002] In the steel rolling and continuous rolling production line, there are generally 3 sets of flying shears: 1# flying shear, 2# flying shear and 3# flying shear, which are respectively located behind the 3 units, and are respectively used for cutting heads, accidental crushing, and finished product times. Segmented ruler. Among them, after each steel billet is rolled, it is cut into several multiples by 3# flying shears, and the multiples of bars cut by 3# flying shears need to be output to the last step of the two-bar rolling system. The process is the cooling of the cold bed, the arrangement of the steel, the cutting to length, the bundling and weighing, and the storage of finished products in the rear area of ​​th...

AI Technical Summary

Problems solved by technology

In the prior art, due to the long distance between the operating table and the cooling bed, the post personnel cannot directly watch the steel on the rack of the cooling bed, and can only watch it through video, but there are certain defects due to video accuracy, angle, etc. Some inconvenience caused by the staff

[0004] In the existing steel rolling and continuous rolling production line, the counting of the steel chain behind the fixed rack of the cooling bed is triggered by the signal of the proximity switch. The proximity switch is installed on the edge of the fixed rack, but because the steel on the fixed rack sometimes has bending The phenomenon of steel or job hopping leads to inaccurate counting of proximity switches, which has a great impact on subsequent process production
