[0046] Considering that electric furnace steelmaking has gradually replaced the traditional blast furnace-converter process with its low energy consumption and low carbon emissions, it has become an important driving force for the transformation of the global steel industry. Continuous breakthroughs in key technologies, such as ultra-high power electric furnaces, scrap preheating, continuous charging, and refining outside the furnace, have improved the smelting efficiency of electric furnaces while limiting energy consumption and carbon emissions.

[0047] At present, during the smelting process, operators at steelmaking posts need to check the data in person at the spectrometer or use telephone or other means to understand the composition data of the molten steel in the furnace, so as to adjust the composition of the molten steel in the furnace according to production requirements.

[0048] However, the current method of transmitting the composition data of the molten steel in the furnace has low work efficiency and portability, and it is difficult to obtain the composition data of the molten steel in the furnace in real time. The timeliness is average, and the composition data of the molten steel transmitted is relatively simple and not comprehensive enough, so it is difficult to adjust the raw materials added during the smelting process in time, and it is easy to produce waste due to inappropriate chemical composition, resulting in high production costs, average control accuracy of the smelting process, and low quality of the molten steel.

[0049] To address this problem, the present application provides a method and system for transmitting chemical composition data in electric furnace smelting, which transmits the chemical composition data detected by the spectral detection equipment to the electric furnace smelting position and the pouring position in real time through data transmission methods such as serial port and TCP communication, so that the operator can view the chemical composition data corresponding to the operator's position in real time according to the position terminal, without having to check the data in person at the spectrometer or understand the data through telephone or other methods, thereby improving work efficiency and portability, and can grasp a more comprehensive chemical composition of the molten steel in the furnace in real time, and timely adjust the raw materials added during the smelting process, so as to more accurately control the smelting process, avoid the generation of waste due to inappropriate chemical composition, thereby reducing production costs and improving the quality of molten steel.

[0050] Figure 1 The flowchart of the chemical composition data transmission method in electric furnace smelting provided by the embodiment of the present application is applied to the chemical composition data transmission system.

[0051] Among them, the chemical composition data transmission system includes spectral detection equipment, production system chemical composition detection post terminal, production system service end, and post terminal. Post terminals correspond to posts, posts include smelting posts and pouring posts; post terminals include smelting terminals and pouring terminals; smelting terminals correspond to electric furnaces one by one. Optionally, the spectral detection equipment includes a spectrometer. For example, Figure 2 As shown, the WIS system terminal represents the chemical composition detection post terminal of the production system, the spectrometer corresponds to the spectral detection equipment, the post terminals are divided into two types, namely the smelting terminal and the pouring terminal, and the corresponding posts are the smelting post and the pouring post. The electric furnace 1 terminal represents the smelting terminal of electric furnace 1, and the electric furnace 2 terminal represents the smelting terminal of electric furnace 2.

[0052] like Figure 1 As shown, the chemical composition data transmission method in electric furnace smelting in the embodiment of the present application may specifically include:

[0053] S101. During the smelting process of the target electric furnace, a molten steel sample of the target electric furnace is obtained by sampling the molten steel of the target electric furnace, and the molten steel sample is sent to a spectrum detection device.

[0054] S102, performing chemical composition detection on the molten steel sample through a spectral detection device to obtain corresponding chemical composition data, and sending the obtained chemical composition data to the chemical composition detection post terminal of the production system through the serial port of the spectral detection device under a preset serial communication mode.

[0055] S103. The chemical composition data is sent in real time to the production system server through the chemical composition detection post terminal of the production system based on a preset TCP communication method. The production system server analyzes the chemical composition data to obtain analyzed chemical composition data.

[0056] S104. The parsed chemical composition data is sent to the corresponding job terminal through the production system server based on the preset socket communication method, so that the operator of the job terminal can view the chemical composition data corresponding to the operator's job in real time on the job terminal, and process the molten steel according to the chemical composition data.

[0057] In the above-mentioned chemical composition data transmission method in electric furnace smelting, the chemical composition data detected by the spectral detection equipment is finally transmitted to the electric furnace smelting position and the pouring position in real time through data transmission methods such as serial port and TCP communication, so that the operator can view the chemical composition data corresponding to the operator's position in real time according to the position terminal, without having to check the data in person at the spectrometer or understand the data through telephone or other methods, thereby improving work efficiency and portability, and can grasp a more comprehensive chemical composition of the molten steel in the furnace in real time, and timely adjust the raw materials added during the smelting process, so that the smelting process can be controlled more accurately, avoiding the generation of waste due to inappropriate chemical composition, thereby reducing production costs and improving the quality of molten steel.

[0058] The above exemplary steps of the embodiment of the present application are described below with reference to specific examples:

[0059] S101, during the smelting process of the target electric furnace, a molten steel sample of the target electric furnace is obtained by sampling the molten steel of the target electric furnace, and the molten steel sample is sent to a spectrum detection device.

[0060] In the embodiment of the present application, the target electric furnace is the electric furnace to be sampled, the smelting process includes smelting and pouring, that is, the positions corresponding to the smelting process include smelting positions and pouring positions, and the molten steel sampling is to collect molten steel samples from the molten steel of the electric furnace for chemical composition analysis. During the smelting process, the molten steel samples of the target electric furnace can be collected manually or automatically, and the molten steel samples are sent to the spectrum detection equipment after cooling and other treatments for subsequent processing. Among them, the spectrum detection equipment includes a spectrometer, or simply understood as a spectrometer, and the spectrometer is a high-precision detection equipment that can accurately measure various chemical components in molten steel.

[0061] Optionally, when sampling the molten steel of the target electric furnace, during the smelting process of the target electric furnace, a first sampling method of sampling the smelting process of the electric furnace and sampling the large package is determined at a preset smelting position, and the molten steel of the target electric furnace is sampled during the smelting process and the large package is sampled based on the first sampling method to obtain the corresponding molten steel sample; during the pouring process of the target electric furnace, a second sampling method of sampling the pouring small package is determined at a preset pouring position, and the molten steel of the target electric furnace is sampled at the pouring small package based on the second sampling method to obtain the corresponding molten steel sample. For example, Figure 2 As shown, smelting process sampling P1-Pn and large ladle sampling T are carried out at the smelting station, and pouring small ladle sampling L1-Ln is carried out at the pouring station, thereby realizing the sampling of molten steel samples.

[0062] Optionally, the chemical composition data transmission system also includes a pneumatic sample delivery device, such as Figure 2 The molten steel sample can be sent to the spectrum detection device through the pneumatic sample delivery device.

[0063] S102, performing chemical composition detection on the molten steel sample through a spectral detection device to obtain corresponding chemical composition data, and sending the obtained chemical composition data to the chemical composition detection post terminal of the production system through the serial port of the spectral detection device under a preset serial communication mode.

[0064] It should be noted that the serial communication method is carried out through a high-quality serial line and a serial converter; the serial port of the serial communication method complies with a preset protocol standard and adopts a preset target baud rate and a target data format.

[0065] Specifically, the present application adopts high-quality serial port cables and serial port converters to avoid data transmission interruptions caused by serial port connection problems, thereby ensuring the stability and reliability of the serial port connection; at the same time, the serial port communication method of the present application follows the preset protocol standard, target baud rate, and target data format. For example, it follows the RS232 protocol standard, uses a baud rate of 9600, an ASCII data format, and sets the serial port number for serial port data transmission to ensure that data can be correctly transmitted between the spectrometer, i.e., the spectral detection device, and the receiving device.

[0066] In the embodiment of the present application, the chemical composition data corresponds to the sampling number of this sampling. After the molten steel sample obtained by sampling in step S101 is sent to the spectral detection equipment, the chemical composition data is obtained by performing chemical composition detection on the molten steel sample through the spectral detection equipment. The spectral detector terminal device sends the chemical composition data to the production system chemical composition detection post terminal device under the preset serial port communication mode. The serial port data receiving program on the chemical composition detection post terminal of the production system receives the chemical composition data for subsequent processing.

[0067] Optionally, a preset chemical composition pre-check threshold is determined, and the chemical composition data of the molten steel sample is pre-checked based on the chemical composition pre-check threshold; in response to at least one component in the chemical composition data of the molten steel sample exceeding the corresponding threshold in the chemical composition pre-check threshold, an alarm is issued through the chemical composition detection post terminal of the production system. The chemical composition pre-check threshold includes the threshold of each chemical component. For example, Figure 3 As shown, this is a page for setting parameters, i.e., pre-inspection thresholds for various chemical components. The pre-inspection thresholds for chemical components are set on this setting page. When the chemical components of the detected samples exceed the thresholds, an alarm can be issued through the chemical composition detection post terminal of the production system to remind the operator to handle the problem.

[0068] Optionally, when the chemical composition of the molten steel sample is tested and the corresponding chemical composition data is obtained, the chemical composition data of the molten steel sample is parsed based on the target data format to obtain the electric furnace furnace number, sampling number, chemical elements and the test data corresponding to each chemical element required by the chemical composition test post terminal of the production system, so as to obtain the corresponding chemical composition data. Specifically, the data received by the serial port is parsed and processed in accordance with the agreed protocol standard and target data format (such as the above-mentioned RS232 protocol standard, the data format is ASCII code), and useful chemical composition data is extracted, and the electric furnace furnace number, sampling number, each chemical element and the corresponding test data required by the production system are parsed according to the target data format.

[0069] It should be noted that there are multiple spectral detection devices in the chemical composition data transmission system, and the spectral detection devices are used alternately to work, thereby solving the data drift problem of the spectral detection devices.

[0070] S103, the chemical composition data is sent in real time to the production system server through the production system chemical composition detection post terminal based on the preset TCP communication method, and the production system server analyzes the chemical composition data to obtain the analyzed chemical composition data.

[0071] In an embodiment of the present application, after the chemical composition data is sent to the chemical composition detection post terminal of the production system, the chemical composition data is sent to the production system server in real time through the production system chemical composition detection post terminal under a preset socket communication mode. After receiving the chemical composition data, the production system server parses the chemical composition data according to the corresponding format to obtain the parsed chemical composition data for subsequent processing.

[0072] S104, the parsed chemical composition data is sent to the corresponding job terminal through the production system server based on the preset socket communication method, so that the operator of the job terminal can view the chemical composition data corresponding to the operator's job in real time on the job terminal, and process the molten steel according to the chemical composition data.

[0073] In the embodiment of the present application, the post terminal corresponds to the post, and the post includes a smelting post and a pouring post; the post terminal includes a smelting terminal and a pouring terminal; after the production system server parses the chemical composition data, the production system server sends the parsed chemical composition data to the corresponding post terminal in real time through a preset socket communication method, so that the operator of the post terminal can view the chemical composition data corresponding to the operator's post in real time on the terminal device of the post terminal, and process the molten steel according to the chemical composition data. For example, Figure 2 As shown, the chemical composition data is sent in real time to the corresponding post terminal, for example, the electric furnace 1 terminal, and the operator of the electric furnace 1 terminal can view the chemical composition data corresponding to the operator's post in real time on the electric furnace 1 terminal, and perform corresponding processing on the molten steel according to the chemical composition data; Figure 4 As shown, the production system server broadcasts the chemical composition data to the respective job terminals, namely, the furnace composition in the figure.

[0074] Optionally, there are multiple post terminals; when the chemical composition data corresponding to the operator's post is viewed in real time on the post terminal, in response to the operator selecting the post number corresponding to the operator's post on the post terminal, the post number is sent to the post terminal; in response to the post terminal receiving the post number, the chemical composition data corresponding to the post number is received and displayed. Specifically, there are multiple posts for smelting and pouring of electric furnaces. The operator of each post only needs to view the data required for the operator's post. The operator selects his own post number on the post terminal, and the chemical composition data required for the post will be displayed on the post terminal, so as to enable the smelting and pouring posts to view the chemical composition data of the sampled molten steel samples in real time. For example, Figure 5 As shown, it represents the chemical composition data displayed on the job terminal (only two components are shown).

[0075] It should be noted that the present application establishes a stable TCP connection and socket communication, which means that programming is performed at the sending end and the receiving end respectively to realize the data sending and receiving functions. Considering the situation of network delay and data packet loss, corresponding measures can be taken to deal with it. For example, data retransmission mechanism, checksum and other methods are used to ensure the integrity of the data. The processing mechanism includes the processing of broken packets, dipped packets, and normal packet data to ensure the integrity of the data for business processing. At the same time, following the RS232 standard protocol, the data format is transmitted in ASCII code. Serial communication is used inside the spectral room where the spectral detection equipment is located. The spectral detection equipment is specifically a spectrometer and a terminal of the chemical composition detection post of the production system to perform data transmission under the USB serial port so that the data can be correctly parsed and displayed at the receiving end. In addition, general data formats such as JSON and XML can be used to process data.

[0076] Therefore, operators do not need to go to the spectrometer to check the data in person or learn about the data by phone, but can directly obtain data in real time at their posts, which greatly improves the convenience of work. Operators can focus more on the control of the smelting process and improve work efficiency. Obtaining spectrum detection data through the serial port can ensure the accuracy of the data. At the same time, the use of TCP communication and socket communication can ensure the stability and reliability of data transmission and reduce errors in the data transmission process.

[0077] Furthermore, by mastering the chemical composition of the molten steel in the furnace in real time, the smelting process can be controlled more accurately and the quality of the molten steel can be improved, which is essential for the production of high-quality steel. For example, when producing special steel, the requirements for chemical composition are very strict, which can help operators better control the chemical composition and improve the quality and performance of the product. At the same time, timely adjustment of raw material additions during the smelting process can avoid the generation of waste products due to inappropriate chemical composition, thereby reducing production costs. In addition, by optimizing the smelting process, production efficiency can be improved, energy consumption can be reduced, and production costs can be further reduced.

[0078] The embodiment of the present application provides a method for transmitting chemical composition data in electric furnace smelting. During the smelting process of a target electric furnace, a molten steel sample of the target electric furnace is obtained by sampling the molten steel of the target electric furnace, and the molten steel sample is sent to a spectral detection device. The molten steel sample is subjected to chemical composition detection by the spectral detection device to obtain corresponding chemical composition data. The obtained chemical composition data is sent to a chemical composition detection post terminal of a production system through the serial port of the spectral detection device under a preset serial communication mode. The chemical composition data is sent to a production system server in real time through the chemical composition detection post terminal of the production system based on a preset TCP communication mode. The production system server parses the chemical composition data to obtain parsed chemical composition data. The parsed chemical composition data is sent to a corresponding post terminal through the production system server based on a preset socket communication mode, so that an operator at the post terminal can view the chemical composition data corresponding to the operator's post in real time on the post terminal and process the molten steel according to the chemical composition data. The chemical composition data transmission method in electric furnace smelting of the present application finally transmits the chemical composition data detected by the spectral detection equipment to the electric furnace smelting position and the pouring position in real time through the data transmission methods such as the serial port and TCP communication, so that the operator can view the chemical composition data corresponding to the operator's position in real time according to the position terminal, without having to check the data in person at the spectrometer or understand the data through the telephone or other methods, thereby improving work efficiency and portability, and can grasp a more comprehensive chemical composition of the molten steel in the furnace in real time, and timely adjust the raw materials added during the smelting process, so as to more accurately control the smelting process, avoid the generation of waste due to inappropriate chemical composition, thereby reducing production costs and improving the quality of molten steel.

[0079] Furthermore, the chemical composition data transmission system includes a large screen in front of the furnace. Figure 2 and Figure 4 shown.

[0080] The parsed chemical composition data is saved in a preset data table through the production system server; the chemical composition data is obtained from the data table through the furnace front large screen and calculated, and the calculated chemical composition data is displayed based on the preset display method, so that the operator can view the chemical composition data from the furnace front large screen. Among them, the data table exists in the database of the production system; the display method includes at least charts and tables.

[0081] Therefore, the chemical composition data is displayed on a large screen in front of the furnace so that operators can easily view the data. At the same time, the data is displayed through intuitive and clear data display interfaces such as charts and tables, presenting the chemical composition data to operators in an easy-to-understand manner.

[0082] Further, the composition range of each chemical component in the chemical composition data of the molten steel sample is determined based on the preset production requirements, and in response to the smelting position finding that at least one chemical component in the chemical composition data of the molten steel sample exceeds the standard or is insufficient (i.e., not within the corresponding composition range), the molten steel is subjected to a first treatment; after the molten steel is subjected to the first treatment, the molten steel of the target electric furnace is sampled again to obtain a new molten steel sample of the target electric furnace, and the new molten steel sample is subjected to a chemical composition test. Among them, the first treatment at least includes blowing oxygen for oxidation desiliconization and decarburization, and adding relevant raw materials.

[0083] Specifically, when the smelting position finds that a certain chemical composition exceeds or is insufficient, the steel will be adjusted by means of oxidation desiliconization and decarburization by blowing oxygen or by adding relevant raw materials, and sampling will be carried out again for chemical composition testing, ultimately ensuring that the chemical composition of the steel produced after the smelting process is completed meets the production requirements.

[0084] Furthermore, when the molten steel is processed according to the chemical composition data, the operator at the smelting station performs a first process on the molten steel based on the preset production requirements and chemical composition data; the operator at the pouring station performs a second process on the molten steel based on the preset production requirements and chemical composition data. The first process at least includes oxidation desiliconization and decarburization; and the second process at least includes quenching and tempering.

[0085] Specifically, after obtaining the chemical composition data of the molten steel sample, the operators at the smelting position can perform oxidation desiliconization, decarburization and other treatments on the molten steel in combination with the production requirements and the chemical composition data; the operators at the pouring position can perform tempering and other treatments on the molten steel in combination with the production requirements and the chemical composition data.

[0086] Furthermore, the target parameters in the smelting process are obtained, and the smelting process of the target electric furnace is controlled and adjusted based on the target parameters and the chemical composition data, wherein the target parameters include at least temperature parameters and pressure parameters.

[0087] Specifically, the chemical composition data can be comprehensively analyzed with other parameters in the smelting process (such as temperature, pressure and other parameters) to adjust various parameters in the smelting process to adjust the smelting process of the target electric furnace.

[0088] It can be added that chemical composition data involves the core technology and business secrets of the enterprise, so effective data security measures need to be taken to prevent data from being stolen or tampered with. This application can use encryption technology to encrypt data transmission, set access rights, install firewalls, etc. to solve these data security problems; different models of spectral detection equipment such as spectrometers and steelmaking equipment may have compatibility issues, and sufficient testing and debugging are required to ensure the normal operation of the system. This application can cooperate with equipment suppliers, follow the RS232 protocol standard, and carry out targeted development and data joint debugging according to the interface information, data transmission format and baud rate between the spectrometer detection program, production system, and chemical composition display equipment to solve equipment compatibility problems; in addition, TCP communication and socket communication rely on the stability of the network. If the network fails, it may cause data transmission interruption. For this, this application can adopt redundant network design, backup communication methods and other measures. The system can be deployed in a distributed manner in the local area network, and load balancing, service governance, distributed locks, data hot standby and other optimization solutions can be carried out at the same time to ensure the robustness and stable operation of the system, high network stability and reliability, and at the same time, network equipment can be regularly maintained and inspected to ensure the normal operation of the network to solve network stability problems.

[0089] In general, electric furnace smelting and pouring positions need to know the chemical composition of molten steel samples in a timely manner. Among them, the electric furnace smelting position needs to master the chemical composition of the molten steel in a timely manner, and perform oxidation desiliconization, decarburization and other treatments on the molten steel so that the molten steel meets production requirements. The pouring position needs to master the chemical composition of the molten steel to temper the molten steel.

[0090] For example, in the process of molten steel sample detection, molten steel is sampled and sent to the spectral detection room where the spectral detection equipment is located by using a pneumatic sample delivery device. The chemical composition of the molten steel sample is detected on the spectrometer, and the sample number is entered into the spectrometer analysis software to save the chemical composition data; then in the process of chemical composition data transmission, the chemical composition data is sent to the production system chemical composition detection post terminal through the serial port. After the serial port data receiving program on the production system chemical composition detection post terminal obtains the chemical composition data, it sends the chemical composition data to the production system server through TCP communication. The production system server parses the chemical composition data and saves it in the corresponding data table, and broadcasts the parsed chemical composition data to the corresponding electric furnace smelting and pouring posts through socket communication. Finally, the smelting and pouring posts view the chemical composition data of the molten steel sample in real time according to the post terminal, and adjust the composition of the molten steel according to the chemical composition data.

[0091] Therefore, this application obtains the chemical composition data detected by the spectral detection equipment through the serial port, and displays the data in real time at the steelmaking post and on the large screen in front of the furnace through TCP communication and socket communication, which can improve the quality of steelmaking, reduce production costs, and promote the development of intelligent steelmaking.

[0092] The embodiment of the present application also provides a chemical composition data transmission system in electric furnace smelting, and the chemical composition data transmission system includes spectral detection equipment, a production system chemical composition detection post terminal, a production system service end, and a post terminal.

[0093] The chemical composition data transmission system in electric furnace smelting is used to execute the chemical composition data transmission method in electric furnace smelting.

[0094] The chemical composition data transmission system in electric furnace smelting provided by the embodiment of the present application, during the smelting process of the target electric furnace, obtains the molten steel sample of the target electric furnace by sampling the molten steel of the target electric furnace, and sends the molten steel sample to the spectral detection equipment, performs chemical composition detection on the molten steel sample by the spectral detection equipment to obtain corresponding chemical composition data, and sends the obtained chemical composition data to the production system chemical composition detection post terminal through the serial port of the spectral detection equipment under the preset serial port communication mode, and sends the chemical composition data to the production system server in real time through the production system chemical composition detection post terminal based on the preset TCP communication mode, the production system server parses the chemical composition data to obtain the parsed chemical composition data, and sends the parsed chemical composition data to the corresponding post terminal through the production system server based on the preset socket communication mode, so that the operator of the post terminal can view the chemical composition data corresponding to the operator's post in real time on the post terminal, and process the molten steel according to the chemical composition data. The chemical composition data transmission system in electric furnace smelting of the present application, by finally transmitting the chemical composition data detected by the spectral detection equipment to the electric furnace smelting position and the pouring position in real time through the data transmission methods such as the serial port and TCP communication, allows the operator to view the chemical composition data corresponding to the operator's position in real time according to the position terminal, without having to check the data in person at the spectrometer or understand the data through the telephone or other methods, thereby improving work efficiency and portability, and can grasp a more comprehensive chemical composition of the molten steel in the furnace in real time, and timely adjust the raw materials added during the smelting process, so as to more accurately control the smelting process, avoid the generation of waste due to inappropriate chemical composition, thereby reducing production costs and improving the quality of molten steel.
