[0044] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings, but it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present disclosure.

[0045] As described in the background technology, the current heating furnace combustion control in steel rolling mills has evolved from instrument automatic control to heating model automatic steel burning control, and the degree of automation has been greatly improved. Different factories and mines have different product structures, and the corresponding billet heating processes are also very different.

[0046] In the related art, when performing the slab heating process, relevant process parameters are usually obtained from the process static table built into the model. However, when the slab structure varies greatly between different production batches, accurate process parameters cannot be issued in time for the heating furnace to operate through the static table built into the model.

[0047] The present invention provides a control method for a steel rolling heating furnace, specifically, obtaining the steel coil number of a target steel coil; according to the steel coil number, querying in a constructed database whether there is a first static table corresponding to the steel coil number, the first static table including production process parameters that meet the contract requirements of the target steel coil; if the first static table exists in the constructed database, the first static table is used as a target static table; the working parameters of the steel rolling heating furnace are obtained based on the target static table; and the steel rolling heating furnace is controlled to produce according to the working parameters. In this way, according to the steel coil number of the target steel coil, it can be queried in the database whether there is a first static table that meets the contract requirements of the target steel coil, and the working parameters of the heating furnace can be obtained based on the target static table, so that the working parameters of the heating furnace can accurately meet the contract requirements, which solves the problem in the related art that when the slab heating process changes, the static table built into the model cannot timely issue accurate process parameters (i.e., working parameters) for the heating furnace to work.

[0048] In addition, in order to reduce production costs, large steel companies usually use the same steelmaking material to obtain products with different performance through different heating processes. In this case, the heating model of the steel rolling furnace needs to obtain the corresponding heating process in a timely manner according to the product performance requirements. At present, it is still at the stage of manually modifying the heating operator through a text contact ticket. At this time, the heating furnace model needs to consider factors such as the timeliness of process control targets and product correspondence, and often cannot be put into automatic steel burning.

[0049] In an embodiment of the present invention, the working parameters can be obtained by analyzing the target static table through the constructed steel burning model. The working parameters at least include the temperature information of the steel rolling heating furnace, thereby reducing manual participation. While the working parameters of the heating furnace are more accurate, the working parameters can also be automatically matched to improve production efficiency and accuracy.

[0050] It should be understood that the control method of the steel rolling heating furnace provided in the embodiment of the present invention can be executed by a target device. The target device can be one electronic device, or multiple electronic devices that cooperate with each other to execute, or a programmable logic controller (PLC) of the heating furnace. The electronic device can be a server, such as an independent physical server, a server cluster composed of multiple servers, and a cloud server capable of cloud computing.

[0051] The technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0052] Figure 1 Flow chart of a control method of a steel rolling heating furnace provided by an embodiment of the present invention. Figure 1 As shown, the control method of the steel rolling heating furnace provided in the embodiment of the present invention includes steps 110 to 140.

[0053] Step 110, obtaining the coil number of the target coil.

[0054] In the embodiment of the present invention, the target steel coil may be any steel coil to be produced, and the steel coil number is the production identification of the target steel coil. The target device may obtain the steel coil number of the target steel coil by obtaining external input, and after the target device obtains the steel coil number of the target steel coil, step 120 may be executed.

[0055] Step 120: query, based on the steel coil number, whether there is a first static table corresponding to the steel coil number in the constructed database, wherein the first static table includes production process parameters that meet the contract requirements of the target steel coil.

[0056] In an embodiment of the present invention, the target steel coil may be a steel coil with special contract requirements, and the special contract requirements may be detailed control parameters during heating, such as heating temperature, heating time and other parameters. When constructing the database, the contract requirements are bound to the steel coil number, so that after the target device obtains the steel coil number, it can query whether there is a first static table corresponding to the steel coil number in the constructed database according to the steel coil number.

[0057] In the embodiment of the present invention, the existence of the first static table can be queried through the constructed database, and can also be queried through other models, such as the automatic steel burning model described below, which is queried in the constructed database. If the first static table exists in the constructed database, steps 130 to 150 can be executed.

[0058] Step 130: If the first static table exists in the constructed database, use the first static table as a target static table.

[0059] In the implementation of the present invention, the target static table is a process static table referenced by the steel rolling heating furnace for production. The target static table includes the contract requirements corresponding to the target steel coil, such as more detailed heating control targets, heating position, heating temperature, residence time and other information.

[0060] Step 140, obtaining the working parameters of the steel rolling heating furnace based on the target static table.

[0061] In an embodiment of the present invention, the data included in the target static table can be directly used as the working parameters of the steel rolling heating furnace, and appropriate adjustments can be made to the data in the target static table, for example, according to the current temperature of the steel rolling heating furnace, or through a neural network model to make slight adjustments based on historical data or training data.

[0062] Step 150, controlling the steel rolling heating furnace to produce according to the working parameters.

[0063] In the embodiment of the present invention, after the steel burning model is calculated, the control targets of each section of the heating furnace are transmitted to the primary instrument to control each heating section of the furnace, so that the heating process of all slabs in the whole furnace meets the specific requirements of the contract.

[0064] In this way, according to the steel coil number of the target steel coil, it is possible to query in the database whether there is a first static table that meets the contract requirements of the target steel coil, and obtain the working parameters of the heating furnace based on the target static table, so that the working parameters of the heating furnace can accurately meet the contract requirements. This solves the problem in the related technology that when the slab heating process changes, the built-in static table in the model cannot timely issue accurate process parameters (i.e., working parameters) for the heating furnace to operate.

[0065] Before obtaining the working parameters of the steel rolling heating furnace based on the target static table in step 140, it also includes: if the first static table does not exist in the constructed database, obtaining the characteristic information of the target steel coil, the characteristic information at least including the material of the target steel coil; according to the characteristic information, querying in the constructed database whether there is a second static table corresponding to the characteristic information, the second static table including production process parameters preset according to the characteristic information; if the second static table exists in the constructed database, using the second static table as the target static table; if the second static table does not exist in the constructed database, an error prompt is given.

[0066] In an embodiment of the present invention, the characteristic information of the target steel coil includes at least one of the material, thickness, hardness and width of the target steel coil. When the second static table is queried according to the characteristic information, the static table with the highest degree of characteristic information matching (i.e., satisfying the most characteristic information) can be used as the second static table, and further as the target static table.

[0067] In an embodiment of the present invention, the second static table may be a process static table preset based on production experience or production equipment characteristics, which may include heating methods classified according to slab steel coil number, raw steel quality, steel grade, sorting degree, and special internal coding of the steel plant (such as APN code).

[0068] In an embodiment of the present invention, if the second static table does not exist in the constructed database, an error prompt may be given, and the error prompt may be a prompt to recheck the input conditions, or that the relevant table cannot be found, etc. The staff may record the error prompt and update the second static table in the database to include more characteristic information of the target steel coil.

[0069] In the embodiment of the present invention, when the first static table does not exist in the constructed database, heating treatment can be performed according to the working parameters included in the second static table to meet the production accuracy of the target steel coil.

[0070] In an embodiment of the present invention, a specific implementation method of obtaining the working parameters of the steel rolling heating furnace based on the target static table in step 140 may include the following steps: analyzing the target static table through the constructed steel burning model to obtain the working parameters, and the working parameters at least include the temperature information of the steel rolling heating furnace.

[0071] In the embodiment of the present invention, the working parameters may include not only the temperature information of the steel rolling heating furnace, such as "the measured temperature of the slab surface", but also the placement position and residence time of the slab. The constructed steel burning model may be a trained neural network model, which may analyze the process standard data included in the target static table to obtain the working parameters of the steel rolling heating furnace, and may also query the constructed database based on the coil number and / or feature information of the target coil.

[0072] In the embodiment of the present invention, part of the code for analyzing and processing by the constructed steel burning model may be as follows:

[0073] log.Info()<<"Initial position of slab:"< <chgData.absc_start<<endl;

[0074] chgData.furNo=p_Fv_pdiaps_furnace.furNo();

[0075] chgData.rowNo=p_Fv_pdiaps_furnace.rowNo();

[0076] if(chgData.slabActLength>5.0)

[0077] {chgData.slabLengthType=3;}

[0078] else

[0079] {if(chgData.rowNo==2*chgData.furNo)

[0080] {chgData.slabLengthType=1;}

[0081] else

[0082] {chgData.slabLengthType=2;}}

[0083] strncpy((char*)chgData.checkTime,p_Fv_pdiaps_furnace.idTime(),sizeof(c hgData.checkTime));

[0084] chgData.LcheckTime=p_Time.createValueTime(p_Fv_pdiaps_furnace.idTime());

[0085] In the embodiment of the present invention, the constructed database provides a visual interface for viewing, and can also provide a visual interface for staff to modify. When matching the heating detailed control target corresponding to the steel coil number, first match the contract heating process static table (i.e., the first static table), and if it cannot be found, then match the process static table built into the heating furnace model (i.e., the second static table), and obtain a unique heating detailed control target corresponding to the steel coil number, and present this process in a visual screen for easy query.

[0086] In the embodiment of the present invention, the database can be constructed by the following steps:

[0087] A database storing a first table and / or a second table is used as a constructed database, wherein the first table includes heating furnace control data obtained according to a contract, and the second table includes heating furnace control data obtained according to production experience.

[0088] In the embodiment of the present invention, the second table can be as follows Figure 2 As shown, the detailed heating control target of each slab that produces a steel coil number is input according to the slab steel code and specification classification. However, when the same steel code corresponds to different contract requirements, the control target is different. Therefore, it is necessary to obtain the heating process control target that meets the contract requirements and will generate the initial data record of the production plan (Product Data Input, referred to as PDI) at the same time as the hot rolling production contract is generated. According to the raw steel, steel type, sorting degree, and APN code, it is decomposed into the detailed heating control target required by the contract, and a contract heating process input screen is established (such as Figure 3 This is a static table of the contract heating process, which does not match the specific slab. Then, a related visual view is established in the database, and the calculation is performed to match the detailed heating control target required by the contract to the specific steel coil number, and the first table is obtained.

[0089] In an embodiment of the present invention, the steel burning model is constructed by the following steps: obtaining training data; and training the steel burning model by using the training data until the steel burning model outputs an optimal value.

[0090] In an embodiment of the present invention, Figure 4 A training concept diagram of a steel burning model provided by an embodiment of the present invention, such as Figure 4 As shown, the training data of the steel burning model provided by the embodiment of the present invention can come from the product contract for special varieties. The contract steel burning target is digitized from text to model, and the key parameter control target method of slab heating is extracted to develop a static table parameter management system for steel burning targets for hot rolling process personnel (such as the constructed database described above). The training data of the steel burning model provided by the embodiment of the present invention can also come from the steel burning process parameter classification method and the parameter analysis of the steel burning target by the original furnace area PDI data. Based on these data, the connection between the furnace area steel burning target data (working parameters) and the factory and mine company's reporting system is established, so as to carry out the intelligent matching method of the production plan and the digital steel burning target, and realize the visual intelligent matching system, so as to train and obtain a model heating control target parameter selection strategy with high accuracy. Finally, the steel burning model is obtained by jointly debugging the key parameter control target method of slab heating and / or the model heating control target parameter selection strategy, and the steel burning model is applied to the control method of the steel rolling heating furnace provided by the embodiment of the present invention to realize accurate control of the heating furnace.

[0091] In order to better understand the control method of the steel rolling heating furnace provided by the embodiment of the present invention, an example is now given. It should be understood that the example is not limiting. The control method of the steel rolling heating furnace provided by the embodiment of the present invention may include the following steps:

[0092] 1. Digitally convert the steel burning target text requirements of special varieties of contracts and provide an input screen specifically for production plant and mine process personnel, such as Figure 3 When the process personnel input the textual requirements for heating of special products in the company's manufacturing system terminal, the specific control targets of the contract for slab heating, such as the upper and lower limits of the furnace time of each heating section, the upper and lower limits of the heating temperature of each heating section, and the excess air coefficient of each heating section, are also input into the screen, and the contract steel burning targets decomposed by raw steel quality, steel type, sorting degree, and APN in the screen are stored in the table of the secondary heating furnace database.

[0093] 2. Establish multiple corresponding views in the table of the secondary computer database of the heating furnace when they are sent to the secondary heating furnace database under the production plan PDI, and classify them according to the raw steel classification PDI, steel grade classification PDI, sorting degree classification PDI, APN code classification PDI and other mixed process classification views. Perform view matching operations according to the production plan matching rules of the research company's manufacturing system until the specific control target digital requirement value of the heating and the corresponding slab are matched.

[0094] 3. When the slab is loaded into the heating furnace, the tracking program of the secondary computer of the heating furnace will first match the specific digital control targets required by the contract in the heating process database view (such as the upper and lower limits of the furnace time of each heating section, the upper and lower limits of the heating temperature of each heating section, and the excess air coefficient of each heating section). If not found, the heating furnace model control target self-learning parameter table will continue to be matched according to the material and steel type to obtain a more detailed and accurate heating control target for the slab in the furnace.

[0095] 4. The heating control target of the slab in the furnace is transmitted to the model program. The automatic steel-burning model will obtain the optimal set temperature value and excess air coefficient of the furnace section according to the heating control target of the slab in the furnace section and transmit them to the instrument automation control system to control the output of the air and gas flow of each furnace section valve to meet the heating process requirements of all slabs.
