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

Embodiment 1

[0050] In the continuous rolling production line, when the steel billet is rolled and transferred to the rear area of ​​the second bar of steel rolling, it is first cut into bars by 3# flying shears on the continuous rolling line, and each bar after being cut by 3# flying shears, The input roller after the 3# flying shear is transported to the apron, and the up and down movement of the apron moves the bars on it to the cooling bed, and the action of the rack on the cooling bed transports each bar to the output roller. , transported to the cold shear through the output roller table for cold shear shearing.

[0051] This embodiment discloses a method for tracking materials in the cooling bed of a continuous rolling production line, such as figure 1 As shown, the steps are as follows:

[0052] Step 1. When powering on the cooling bed, initialize the data state of each slot on each rack of the cooling bed, and initialize them to a steel-free state;

[0053] Step 2. In each cycle...

Embodiment 2

[0064] This embodiment discloses a cooling bed material tracking device for a continuous rolling production line, including:

[0065] The initialization unit is used to initialize the data state of each slot on each rack of the cooling bed when the cooling bed is powered on, all of which are initialized to a steel-free state;

[0066] The identification unit is used to identify whether there is steel lowering on the cooling bed when the skirt board is currently in motion;

[0067] The first groove state marking unit is used to mark the state of the first groove on the rack as the state of the rod tail after the skirt performs the action when the steel is transferred to the cooling bed under the action of the skirt; it is used for When the data state is shifted, the state of the first slot of the rack is marked as the state of no bar tail gauge; the first slot of the rack is the slot closest to the skirt side; it is used for the data of each slot When the state is shifted ever...

Embodiment 3

[0077] This embodiment discloses a continuous rolling production line cooling bed material tracking system, such as figure 2 As shown, it includes main control unit, steel signal detector, hot metal detector and flying shear detector. In this embodiment, the main control unit may be a PLC.

[0078] The steel signal detector is used to detect the motor current of the rolling mill in the rolling area. When the motor current is detected to be greater than a certain threshold, it is judged that there is steel in the rolling area, and a steel signal is sent to the main control unit. In the steel signal detector in this embodiment, when the motor current is detected to be greater than 15% to 20% of the rated current, it is judged that there is steel in the rolling area, and a steel signal is sent to the main control unit.

[0079]The hot metal detector is installed on the continuous rolling production line before the first flying shear to detect whether there is a billet passing b...

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...
