Description

Technical Field

[0001] This invention relates to the field of iron and steel smelting technology, specifically to a scrap steel batching system and method. Background Technology

[0002] In converter steelmaking, scrap steel is one of the main metal raw materials, and the accuracy and efficiency of its batching directly affect the quality of molten steel, smelting cycle, and production costs. Traditional scrap steel batching methods rely primarily on manual operation. Operators use overhead cranes to hoist scrap steel into scrap hoppers according to paper batching lists, then weigh the steel using weighing instruments and manually record the data. This operating mode has the following drawbacks: (1) Low batching accuracy: Manual reading and recording of weighing data is prone to errors and lacks a real-time feedback mechanism, which causes the scrap steel ratio to deviate from the planned value and affects the stability of the molten steel composition.

[0003] (2) The operation process is complicated: it requires manual verification of the type and weight of scrap steel and filling in paper reports. The workload is heavy, the efficiency is low, and it is easy to make mistakes or omissions.

[0004] (3) Data silos: Ingredient data are scattered in paper records of different shifts, making it difficult to achieve data sharing and traceability across shifts, which is not conducive to production management and quality analysis.

[0005] (4) Lack of linkage with the furnace front system: After the batching is completed, the data cannot be automatically transmitted to the furnace front control system. Operators need to transmit information by telephone or walkie-talkie, which affects the precise control of the smelting rhythm. Summary of the Invention

[0006] (a) Technical problems to be solved The technical problem to be solved by the present invention is to provide a scrap steel batching system and method, which realizes precise control of scrap steel batching, automatic data recording and sharing, and multi-shift collaborative operation through modular design and automated process.

[0007] (II) Technical Solution To solve the above-mentioned technical problems, the technical solution provided by the present invention is a scrap steel batching system, characterized in that it includes: The login authentication module is used to verify user identity and ensure system operation permissions and data security; The multi-bucket scrap steel batching module is used to manage the batching process of multiple scrap steel hoppers in parallel, including tare weighing, scrap steel type selection, planned value input, and loading start and end control. It can also automatically determine the end of batching of a single type of scrap steel and the end of total loading based on the batching status, and send relevant data. The performance report management module is used to automatically record all weighing data and send it to the furnace front system. It supports querying batching data by time period and provides data export function to facilitate cross-shift verification and analysis.

[0008] As an improvement, the multi-bucket scrap steel batching module supports parallel batching operations for scrap steel hoppers 1 to 5.

[0009] As an improvement, the multi-bucket scrap steel batching module includes a tare function unit, which is used to remove the weight of the scrap steel bucket before weighing to ensure weighing accuracy.

[0010] As an improvement, the multi-bucket scrap steel batching module includes a general loading control unit, which controls the start and end of the entire batching batch, and automatically triggers data transmission to the furnace front system after all types of scrap steel have been loaded.

[0011] As an improvement, the multi-bucket scrap steel batching module supports switching of scrap steel types and allows operators to input planned values ​​for each type of scrap steel.

[0012] As an improvement, the performance report management module includes a query unit and an export unit. The query unit is used to retrieve ingredient records according to the time period selected by the user, and the export unit is used to export the query results as an external file.

[0013] A scrap steel batching method, applied to the aforementioned scrap steel batching system, is characterized by comprising the following steps: (1) Users authenticate their identity through the login authentication module and enter the system; (2) The operator selects the scrap steel bucket number in the multi-bucket scrap steel batching module and performs the tare operation; (3) Click "Start Assembly" to begin the batching process for the current batch; (4) Enter the planned value for the current scrap steel type, select the scrap steel type, and click "Loading Start"; (5) Once a certain type of scrap steel has been batched, click "Finish Batching" and switch to the next type of scrap steel, repeating the loading steps. (6) After all types of scrap steel have been batched, click "Complete Loading" and the system will automatically send the weighing data to the furnace front system. (7) The performance report management module automatically records all data and supports querying and exporting by time period.

[0014] As an improvement, the system automatically determines whether the termination condition is met after each type of scrap steel batching is completed, and prompts the operator to proceed to the next step.

[0015] As an improvement, the performance report management module automatically generates traceable batching records after the data is sent to the furnace front system, which facilitates cross-shift verification.

[0016] (III) Beneficial Effects The advantages of this invention compared to the prior art are: (1) The tare function eliminates the influence of the self-weight of the scrap steel bucket, automatically collects weighing data, and reduces human reading errors.

[0017] (2) One-click operation and process guidance are adopted to simplify manual intervention, support multi-bucket parallel operation, and shorten the batching cycle.

[0018] (3) The entire process of data from batching to reporting is automatically recorded and sent to the furnace front system in real time, providing data support for the optimization of the smelting process.

[0019] (4) Data is traceable and exportable, which facilitates information exchange and verification between different shifts and improves management transparency. Detailed Implementation

[0020] The invention will now be described in further detail with reference to specific embodiments, but this should not be construed as limiting the scope of the subject matter of the invention to the following embodiments.

[0021] This embodiment provides a scrap steel batching system. The system is built based on an industrial control computer and a programmable logic controller (PLC), and connects to the furnace front secondary system via Ethernet communication. The operation interface is deployed on an industrial touch screen for easy on-site operation.

[0022] 1. Login Authentication Module After the system starts, a login interface is displayed. Operators enter their employee ID and password, which are then compared with the user permission database in the system backend. Upon successful verification, appropriate operating permissions are assigned based on the user's role (e.g., operator, shift leader, administrator). This module ensures that only authorized personnel can access the system, preventing accidental operations and data leaks.

[0023] 2. Multi-bucket scrap steel batching module The system's main interface displays the status information of scrap steel hoppers 1 through 5. Each scrap steel hopper corresponds to an independent weighing channel, and the weighing sensor collects weight data in real time and displays it on the interface. The operation process is as follows: Select scrap steel hopper: The operator clicks on the scrap steel hopper number that needs to be filled, and the hopper is activated.

[0024] Tare operation: Click the "Tare" button, the system records the current empty bucket weight and automatically zeros it, and the subsequent weighing value is the net weight of the scrap steel.

[0025] Start Batch: Click the "Start Loading" button. The system will record the current time as the batch start time and allow subsequent batching operations.

[0026] Enter planned weight and select type: Enter the planned weight value for the current scrap steel type in the input box, and select the scrap steel type code from the drop-down menu. Scrap steel type codes are pre-maintained in the system dictionary, including heavy scrap steel, medium scrap steel, and shredded material.

[0027] Start loading: Click the "Start Loading" button, and the system will start monitoring the weight change of the bucket in real time. When the actual weight reaches the planned value, a prompt will pop up on the interface, or the operator can manually click "Filling End" to complete the feeding of this type of material according to the on-site situation.

[0028] Once a particular type of scrap steel has been batched, the operator clicks the "Batching Complete" button, and the system records the actual weight of that type. To add other types of scrap steel, the operator switches the scrap steel type and clicks "Loading Start" again, repeating the process. When all types of scrap steel have been batched, the operator clicks the "Total Loading Complete" button, and the system automatically sends the batching data for all scrap steel hoppers in that batch (including hopper number, scrap steel type, planned value, actual value, start time, and end time) to the furnace front-end secondary system via industrial Ethernet for subsequent smelting model calculations and guidance.

[0029] The multi-bucket scrap steel batching module supports the simultaneous operation of multiple scrap steel buckets without interference, significantly improving batching efficiency.

[0030] 3. Performance Report Management Module The performance report management module provides historical data query and export functions. Operators or managers can select the start and end times in the interface and click the "Query" button. The system will then retrieve all material batching records within that time period from the local database or server and display them in a table format, including fields such as batch number, scrap steel bucket number, scrap steel type, planned value, actual value, operator, and timestamp.

[0031] Clicking the "Export" button will export the query results as an Excel or CSV file, making it easy to save, print, or pass on to the next shift during shift handover. This module enables full-process electronic recording and traceability of ingredient data, solving the problems of easy loss and difficulty in sharing traditional manual records.

[0032] System Workflow The specific steps of the scrap steel batching method in this embodiment are as follows: S1: Operators enter their employee ID and password through the login authentication module to verify their identity and enter the main interface.

[0033] S2: Select the currently operating bucket from scrap steel buckets 1 to 5, and click the "Tare" button to clear the bucket weight effect.

[0034] S3: Click the "Start Assembly" button to start the batch material preparation process.

[0035] S4: Enter the planned weight value for the current scrap steel type, select the corresponding scrap steel type from the drop-down list, and click "Start Loading".

[0036] S5: The crane operator loads scrap steel into the hopper, and the system displays the weight in real time; after the planned value is reached, the operator clicks "Filling Complete", and the system records the actual weight of that type.

[0037] S6: If you need to add other types of scrap steel, repeat steps S4-S5 after switching types.

[0038] S7: After all types of ingredients are prepared, click the "Complete Loading" button. The system will automatically package and send all ingredient data for this batch to the furnace front system.

[0039] S8: In the performance report management module, historical ingredient records can be queried at any time by time period and exported as a file for subsequent analysis or handover.
