Description

Technical Field

[0001] The present invention relates to the technical field of billet production, and specifically to an automatic tracking method for billet numbers in the hot charging state of a square billet continuous caster. Background Art

[0002] The square billet continuous caster produces billets in multiple strands. After the billets are cut by a hydraulic shear, due to the limitations of the rolling specifications in the rolling process, some are sent to the rolling production line directly through the hot charging roller table for rolling, and the other part is transported to the rolling production line by truck through the reversing cooling bed on the turning machine for rolling. In this process, the automatic tracking and transmission of billet numbers are particularly important. If the billet numbers cannot be automatically tracked, the billet information data cannot be automatically collected and transmitted, which cannot meet the information-based billet data requirements of the steelmaking process in the steel rolling mill. At the same time, the rolling process cannot carry out batching production due to the lack of billet number information. Summary of the Invention

[0003] The purpose of the present invention is to solve the technical problems existing in the above-mentioned prior art, and provide an automatic tracking method for billet numbers in the hot charging state of a square billet continuous caster.

[0004] The present invention provides the following technical solution: An automatic tracking method for billet numbers in the hot charging state of a square billet continuous caster, which adopts a hot charging detection system. The hot charging detection system includes a plurality of billet discharging roller tables arranged at the discharging end of the continuous caster. A hot charging roller table in the confluence area is provided at the rear end of the billet discharging roller tables. The output end of the hot charging roller table in the confluence area is connected to a steel rolling and hot charging transfer roller table. Lifting baffles are provided on each of the plurality of billet discharging roller tables, and a hot charging detection device A is provided on each billet discharging roller table. A hot charging detection device B is provided on the steel rolling and hot charging transfer roller table. The specific method is as follows: S1. The plurality of billet discharging roller tables are divided into hot charging strands and cold bed strands according to production needs. For the hot charging strands, the lifting baffles are sequentially lowered in sequence to release the billets, and a discharging interval time is set for each strand to achieve the first-in, first-out of the billets. S2. The steelmaking L1 system sends a "shearing start" signal to the steelmaking L2 system, and the steelmaking L2 system transmits the produced billet number to the steelmaking L1 system. The steelmaking L1 system stacks and sorts the billet numbers transmitted by the steelmaking L2 according to the "shearing end" signal. For the cold bed strands, the lifting baffles block the billets. When the steelmaking L1 system detects the "turning machine action" signal, it determines that the billet number is a cold bed billet number, and transmits the billet number to the steelmaking L2 system. The steelmaking L2 system determines that the billet number goes to the cold bed and transmits the billet number to the steelmaking L3 system. The steelmaking L3 system collects the cold bed billet number information and uploads the information to the production and sales system. The production and sales system receives the cold bed billet number information and uploads the information to the rolling L3 system. The rolling L3 system receives the billet number information, forms a batching plan and issues it to the rolling L2 system. The rolling L2 system receives the billet number information, automatically matches the billet number of the batching plan to form rolling information and transmits the information to the rolling L3 system. S3. For the hot charging strand, the lifting baffle drops to send out the hot charged billet. When the steelmaking L1 system detects a "billet present" signal through the hot charging detection device A, it determines that the billet number is the hot charging billet number. When the steelmaking L1 system adds this billet number to the top storage during stack sorting of the hot charging billet numbers, and the hot charging detection device B at the hot charging transfer roller table between the steelmaking L1 system and the rolling mill detects a "billet present" signal, the steelmaking L1 system transmits the billet number at the bottom of the stack sorting storage to the steelmaking L2 system. The steelmaking L2 system receives the hot charging billet number, determines that the billet number is for hot charging completion, and transmits the billet number to the steelmaking L3 system. The steelmaking L3 system collects the hot charging billet number information and uploads the information to the production and sales system. The production and sales system receives the hot charging billet number information and uploads the information to the rolling mill L3 system. The rolling mill L3 system receives the billet number information, forms a batching plan, and issues it to the rolling mill L2 system. The rolling mill L2 system receives the billet number information, automatically matches the billet number in the batching plan to form rolling information, and transmits this information to the rolling mill L3 system; S4. The steelmaking L1 system transmits the billet number at the bottom of the stack sorting storage to the rolling mill L1 system, and at the same time subtracts this billet number from the bottom of the stack sorting storage. The rolling mill L1 system receives the hot charging billet number, detects a "entering the rolling mill" detection signal for this hot charging billet number, and transmits the signal to the rolling mill L2 system. The rolling mill L2 system receives the billet number information, automatically matches the billet number in the batching plan to form rolling information, and transmits this information to the rolling mill L3 system.

[0005] Furthermore, it also includes S5. For the billets on the cooling bed, when they are sent to the rolling mill system, the rolling mill L1 system detects a "billet number on the cooling bed entering the heating furnace" signal and transmits the billet number to the rolling mill L2 system. Then the billet number enters the rolling line roller table. The rolling mill L1 system detects a "entering the rolling mill" detection signal for this hot charging billet number and transmits the signal to the rolling mill L2 system. The rolling mill L2 system receives the billet number information, automatically matches the billet number in the batching plan to form rolling information, and transmits this information to the rolling mill L3 system.

[0006] Furthermore, the steelmaking L1 system and the rolling mill L1 system are basic automation control systems, which are used to control the hot charging production equipment and related process flows, and automatically track and transmit the hot charging status billet numbers transferred from the steelmaking L2 system / rolling mill L2 system throughout the process.

[0007] Furthermore, the steelmaking L2 system and the rolling mill L2 system are process control systems, which are used to receive the production plans sent from the steelmaking L3 system / rolling mill L3 system, and generate process tracking actual performance data by collecting data from the steelmaking L1 system / rolling mill L1 system according to the production plans, and transmit the generated process tracking actual performance data to the steelmaking L3 system / rolling mill L3 system to form queryable reports.

[0008] Furthermore, the steelmaking L3, rolling L3 systems and production, sales and distribution system are production management systems. They form a production plan by grouping furnaces and billets according to sales orders and send the plan to the steelmaking L2 system / rolling L2 system. At the same time, they receive the data transmitted from the steelmaking L2 system / rolling L2 system to form a corresponding billet number tracking information report.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: It can automatically track the billet number throughout the process, not only meeting the billet number data collection requirements of the L2 and L3 systems in the steelmaking process, but also accurately transmitting the billet number information to the L3 system in the rolling process for planned batching. At the same time, the billet number information is also transmitted to the hot delivery PLC system in the rolling process to meet the data collection requirements of the L2 and L3 systems in the rolling process, ultimately meeting the functions of automatic tracking, data transmission and collection of the billet number throughout the process under the hot delivery state.
