Description

Technical Field

[0001] The present disclosure relates to a technology for optimizing the operation of a heating furnace. Specifically, the present disclosure relates to a technology for calculating the optimal temperature for operating a heating furnace using artificial intelligence. Background Art

[0002] With the development of artificial intelligence technology, artificial intelligence technology is being widely used in various industrial fields. In particular, the research on using artificial intelligence models to optimize the operation of steel product production processes has attracted much attention recently.

[0003] In order to produce steel products of target quality, the physical properties of the steel plate must be changed by performing appropriate heat treatment in a heating furnace. However, the physical properties of the steel plate do not change linearly with the heat treatment, but show a nonlinear relationship of sharp change when the heat treatment is performed above the appropriate temperature, and the effect of the heat treatment temperature on the change of the physical properties varies with various reasons such as the composition of the steel plate, the thickness of the steel plate or the operating environment. Therefore, there is a limitation that it is difficult to accurately handle the heat treatment that causes the change of the physical properties of the steel plate. In addition, since the heat treatment depends on the experience of the operator, even if the same steel product is produced, the furnace temperature and operating conditions set by different operators will be different, so there are limitations in ensuring the stability of the quality of the steel product. In order to solve these problems, although the technology of optimizing the steel process has been developed, the existing steel process optimization technology is only used to stably control the steel process, and it is impossible to calculate the optimal operating temperature of the heating furnace, which is a limitation.

[0004] Therefore, it is necessary to develop a method for calculating the optimal temperature of a heating furnace and a device for executing the method, so as to improve thermal efficiency while ensuring the stability of the quality of steel products. Summary of the invention

On the other hand, when describing the method for calculating the optimal temperature of the heating furnace, the above-mentioned Figures 1 to 3 The contents described are repeated in some embodiments. However, this is only for the convenience of explanation and should not be construed as limiting.

[0072] Figure 4 is a sequence diagram illustrating a method for calculating an optimal temperature of a heating furnace according to an embodiment of the present disclosure.

[0073] According to one embodiment of the present disclosure, a method for calculating the optimal temperature of a heating furnace may include: a step S1000 of obtaining a target physical property value of a material input by an operator; a step S2000 of obtaining a plurality of appropriate candidate temperatures of a heating furnace from first input data using a trained optimal temperature model; a step S3000 of obtaining an expected physical property value of a material from a second input data using a trained physical property prediction model; a step S4000 of sampling a plurality of appropriate candidate temperatures to obtain at least one sampled appropriate candidate temperature; a step S5000 of obtaining thermal information when the heating furnace is operated at the sampled appropriate candidate temperatures, comparing the thermal information, and filtering the sampled appropriate candidate temperatures to obtain at least one appropriate temperature; a step S6000 of calculating an optimal temperature based on the appropriate temperatures; and / or a step S7000 of sending a request for indicating that the calculated optimal temperature is set as the set temperature value of the heating furnace.

[0074] In step S1000 of obtaining the target property value of the material input by the operator, the electronic device 1000 may obtain the target property value related to the target property information of the product input by the operator of the heating furnace through the transceiver 1100. The target property value may be a value related to any target property of the heat-treated material, including tensile strength, yield strength, hardness and / or elongation of the material heat-treated by the heating furnace.

[0075] In step S2000 of obtaining multiple appropriate candidate temperatures of the heating furnace from the first input data using the trained optimal temperature model, the electronic device 1000 can obtain multiple appropriate candidate temperatures of the heating furnace from the first input data including the thickness of the material to be heated in the heating furnace, the steel type of the material, the operating speed of the heating furnace, the target physical property value obtained by step S1000 and / or their combination as variables.

[0076] Figure 5 1 is a diagram for explaining a method for training an optimal temperature model according to an embodiment of the present disclosure and a form of calculating an appropriate candidate temperature using the trained optimal temperature model. Specifically, Figure 5 (a) is a diagram showing a form of calculating an appropriate candidate temperature using a trained optimal temperature model according to an embodiment of the present disclosure, Figure 5 (b) is a diagram illustrating a training method of an optimal temperature model according to an embodiment of the present disclosure.

[0077] The trained optimal temperature model can obtain the first input data through the input layer, and calculate multiple appropriate candidate temperatures ( Figure 5 (a) T1, T2 to Tn), and output the calculated multiple suitable candidate temperatures through the output layer. At this time, the electronic device 1000 can obtain multiple suitable candidate temperatures through the output layer of the trained optimal temperature model.

[0078] On the other hand, the optimal temperature model can be trained based on a first learning data consisting of the thickness of the material, the steel type of the material, the operating speed of the heating furnace, the target physical property value and / or a combination thereof obtained from the heating furnace operation database, and a learning data set consisting of the operating temperature of the heating furnace corresponding to the first learning data. More specifically, the optimal temperature model can be configured to output a predicted temperature based on the first learning data. At this time, the optimal temperature model is trained by updating the parameters (or weights) of the optimal temperature model based on the difference between the predicted temperature and the operating temperature of the heating furnace contained in the learning data set so as to output the predicted temperature at a value approximating the operating temperature of the heating furnace. Therefore, the trained optimal temperature model can be configured to calculate an appropriate candidate temperature corresponding to the actual operating temperature of the heating furnace based on the first input data corresponding to the variables of the first learning data.

[0079] In step S3000 of obtaining the expected physical property value of the material from the second input data using the trained physical property prediction model, the electronic device 1000 can obtain the expected physical property value of the material from the second input data including the appropriate candidate temperature calculated in step S2000, the thickness of the material, the steel type of the material, the operating speed of the heating furnace and / or a combination thereof as variables using the trained physical property prediction model. The expected physical property value may be an expected value related to any physical property of the material to be heat treated, including the tensile strength, yield strength, hardness and / or elongation of the material to be heat treated by the heating furnace.

[0080] Figure 6 is a diagram for illustrating a method for training a physical property prediction model according to an embodiment of the present disclosure and a form of calculating expected physical property values ​​using a trained physical property prediction model. Specifically, Figure 6 (a) is a diagram showing a form of calculating expected physical property values ​​using a trained physical property prediction model according to an embodiment of the present disclosure, Figure 6 (b) is a diagram illustrating a method for training a physical property prediction model according to an embodiment of the present disclosure.

[0081] The trained physical property prediction model can obtain the second input data through the input layer, and calculate the expected physical property value (for example, Figure 6(a) The expected physical property value Q1 related to the tensile strength, the expected physical property value Q2 related to the yield strength, the expected physical property value Q3 related to the hardness, and the expected physical property value Q4 related to the elongation), and the calculated expected physical property values ​​are output through the output layer. At this time, the electronic device 1000 can obtain the expected physical property values ​​through the output layer of the trained physical property prediction model.

[0082] On the other hand, the physical property prediction model can be trained based on the second learning data consisting of the thickness of the material, the steel type of the material, the operating speed of the heating furnace, the operating temperature of the heating furnace and / or a combination thereof obtained from the heating furnace operation database and a learning data set consisting of the physical property information when the material is heat treated under the operating conditions corresponding to the second learning data. More specifically, the physical property prediction model can be configured to output the physical property information as a related predicted value based on the second learning data. At this time, the physical property prediction model can update the parameters (or weights) of the physical property prediction model based on the difference between the predicted value and the physical property information contained in the learning data set so as to output the predicted value as a value approximating the physical property information. Therefore, for example, the trained physical property prediction model can be configured to calculate the expected physical property value when the material is heat treated at an appropriate candidate temperature calculated by the trained optimal temperature model based on the second input data corresponding to the variables of the second learning data and under the operating conditions corresponding to the second input data.

[0083] Figure 7 FIG. 1 is a diagram for explaining a method of calculating an optimal temperature from appropriate candidate temperatures according to an embodiment of the present disclosure.

[0084] In step S4000 of sampling multiple appropriate candidate temperatures to obtain at least one sampled appropriate candidate temperature, the electronic device 1000 may perform the action of sampling multiple appropriate candidate temperatures and obtaining the sampled appropriate candidate temperatures. Specifically, the electronic device 1000 may be configured to compare the target property value input by the operator with the expected property value calculated by the trained property prediction model according to the appropriate candidate temperature, and sample multiple appropriate candidate temperatures calculated by the trained optimal temperature model. For example, the electronic device 1000 may calculate the target property value input by the operator and the expected property value calculated by the trained property prediction model according to the first appropriate candidate temperature (for example, Figure 7 For example, the electronic device 1000 may calculate the target property value input by the operator and the first expected property value calculated by the trained property prediction model according to the second appropriate candidate temperature (e.g., Figure 7For example, the electronic device 1000 may calculate the target property value input by the operator and the second expected property value calculated by the trained property prediction model according to the nth appropriate candidate temperature (e.g., Figure 7 The nth difference between the nth expected property values ​​calculated by Tn).

[0085] As an example, the electronic device 1000 may sort the multiple suitable candidate temperatures in ascending order of the difference between the target property value and the expected property value based on the difference between the target property value and the expected property value. In addition, the electronic device 1000 may be configured to determine, based on the sorting result, the multiple suitable candidate temperatures corresponding to the expected property values ​​that fall within the predetermined order as the sampled suitable candidate temperatures ( Figure 7 As an example, the electronic device 1000 may be configured to determine a plurality of suitable candidate temperatures corresponding to the expected physical property values ​​whose calculated differences fall within a predetermined value as suitable candidate temperatures for sampling ( Figure 7 ST1, ST2 to STm).

[0086] However, the above is merely an example, and the electronic device 1000 may be configured to sample a plurality of suitable candidate temperatures based on any suitable method.

[0087] In step S5000 of obtaining heat information when the heating furnace is operated at the sampled appropriate candidate temperature, comparing the heat information, and filtering the sampled appropriate candidate temperature to obtain at least one appropriate temperature, the electronic device 1000 may obtain each heat information when the heating furnace is operated at each sampled appropriate candidate temperature. For example, the electronic device 1000 may obtain the heat information when the heating furnace is operated at the sampled first appropriate candidate temperature (e.g., Figure 7 The heat information used when the heating furnace is operated under ST1 of Figure 7 For example, the electronic device 1000 may obtain a second suitable candidate temperature (eg, Figure 7 The heat information used when operating the heating furnace under ST2) (for example, Figure 7 For example, the electronic device 1000 may obtain the mth appropriate candidate temperature (eg, Figure 7 The heat information used when operating the heating furnace under STm (for example, Figure 7 mth heat).

[0088] At this time, the electronic device 1000 can compare the acquired heat information and filter the multiple sampled appropriate candidate temperatures to obtain at least one appropriate temperature. Specifically, the electronic device 1000 can sort the multiple sampled appropriate candidate temperatures in order of heat from small to large based on the heat information. At this time, the electronic device 1000 can be configured to determine the multiple sampled appropriate candidate temperatures corresponding to the heat that fall into the predetermined order as at least one appropriate temperature based on the sorting result (for example, Figure 7 OT1 to OTk).

[0089] However, the above is merely an example, and the electronic device 1000 may be configured to acquire a plurality of appropriate temperatures from a plurality of sampled appropriate candidate temperatures based on any appropriate method.

[0090] In step S6000 of calculating the optimal temperature based on a plurality of appropriate temperatures, the electronic device 1000 may be configured to calculate an average value of the appropriate temperatures as the optimal temperature. For example, the electronic device 1000 may calculate a plurality of appropriate temperatures (eg, Figure 7 The average value of the first appropriate temperature (OT1) to the kth appropriate temperature (OTk) is calculated, and the average value of the calculated appropriate temperatures is determined as the optimal temperature.

[0091] On the other hand, although Figure 4 Although not shown in the figure, the method for calculating the optimal temperature of the heating furnace according to an embodiment of the present disclosure may be configured to calculate the optimal temperature by repeating steps S2000 to S6000 multiple times.

[0092] In step S7000 of sending a request for instructing to set the calculated optimal temperature as the set temperature value of the heating furnace, the electronic device 1000 may be configured to send a request for instructing to set the calculated optimal temperature as the set temperature value of the heating furnace to the heating furnace controller 200 through the transceiver 1100. At this time, the heating furnace controller 200 may be configured to set the set temperature value of the heating furnace 100 to the calculated optimal temperature in response to the request. In addition, the heating furnace controller 200 may perform an operation of controlling the operating temperature of the heating furnace to the set temperature value based on the operating temperature of the heating furnace 100 and the set temperature value.
