[0030] Embodiment 1

[0031] Figure 1 A flowchart of a molten iron ladle energy adjustment method is provided for Embodiment 1 of the present invention. This embodiment is applicable to the situation where the castings cannot meet the process standards due to energy loss during the transportation of the molten iron ladle. This method can be executed by a molten iron ladle energy adjustment device, which can be implemented in the form of hardware and / or software, and can be configured in a personal computer or a server. As Figure 1 shown, the method includes:

[0032] S101. Obtain the initial energy of the molten iron ladle and the influencing factors.

[0033] A molten iron ladle is a casting equipment for pouring operations, used for pouring operations in a foundry workshop. It receives molten iron in front of the furnace and then is transported to the casting mold by a traveling crane for pouring.

[0034] During the transportation of the molten iron ladle, the energy of the molten iron in the ladle will be lost due to various factors. The influencing factors are the factors on the production line where the molten iron ladle is located that affect the energy loss of the molten iron in the ladle. Exemplarily, such as the time required for transportation, the coverage rate of the heat insulation agent on the surface of the molten iron ladle, and so on.

[0035] Obtain the initial energy of the molten iron after the molten iron ladle receives it in front of the furnace, as well as the data of each influencing factor, for subsequent prediction of the energy loss of the molten iron ladle during transportation.

[0036] It should be noted that the influencing factors in the embodiments of the present invention include the time required for transportation, and the coverage rate of the heat preservation agent on the surface of the ladle is an exemplary illustration of the embodiments of the present invention. In other embodiments of the present invention, other influencing factors may also be included. The embodiments of the present invention are only examples and are not limited.

[0037] S102. Predict the lost energy of the ladle based on the influencing factors.

[0038] During the transportation of the ladle, there is a certain correlation between the influencing factors and the molten iron energy of the ladle. The influencing factors are used to predict the energy lost by the ladle during transportation.

[0039] The present invention does not limit the method of predicting the lost energy of the ladle based on the influencing factors.

[0040] In some embodiments of the present invention, S102 includes:

[0041] S1021. Calculate the energy loss coefficient of the ladle based on the influencing factors.

[0042] The influencing factors have a certain regularity and correlation with the energy loss of the ladle. The energy loss coefficient of the ladle is determined based on the data of the influencing factors. The energy loss coefficient is the proportion of the energy value of the predicted lost energy to the total initial energy value.

[0043] Exemplarily, each different value of the influencing factors has a corresponding sub-energy loss coefficient. The sub-energy loss coefficient corresponding to the current influencing factor is obtained by searching, and the sub-energy loss coefficients corresponding to all influencing factors are multiplied to obtain the energy loss coefficient of the ladle.

[0044] Exemplarily, by querying the correlation curve of all influencing factors and the energy loss coefficient, the corresponding energy loss coefficient of the ladle is obtained.

[0045] It should be noted that the calculation of the energy loss coefficient of the ladle based on the influencing factors listed in the embodiments of the present invention is an exemplary illustration of the embodiments of the present invention. In other embodiments of the present invention, there may be other methods for calculating the energy loss coefficient of the ladle. In the embodiments of the present invention, only examples are given and are not limited.

[0046] S1022. Multiply the initial energy by the energy loss coefficient to obtain the lost energy of the ladle.

[0047] The energy loss coefficient is the proportion of the energy value of the predicted lost energy to the total initial energy value. Multiply the initial energy by the energy loss coefficient to obtain the energy lost by the ladle during transportation.

[0048] The present invention is only an example and is not limited.

[0049] S103. Subtract the loss energy from the initial energy to predict the first energy when the ladle reaches the destination point.

[0050] Subtract the loss energy dissipated during transportation from the initial energy of the molten iron in the ladle after receiving it in front of the furnace to predict the first energy when the molten iron reaches the destination point at the mold.

[0051] The present invention is only for illustration and not for limitation.

[0052] S104. Compare the first energy with a preset energy threshold range to obtain the energy state of the ladle.

[0053] The energy of the ladle when it reaches the destination point is not an exact value. A certain range of energy threshold is preset in advance. The molten iron energy within this energy threshold range can meet the molten iron energy required by the process, ensure that the carbon content and oxygen content of the casting meet the process requirements, and casting forming within this energy threshold range can save the materials used in other casting processes and reduce the cost of steelmaking.

[0054] Compare the predicted first energy when reaching the destination point with the preset energy threshold range, judge the relationship between the first energy of the molten iron in the ladle and the energy threshold range, and obtain the current energy state of the molten iron in the ladle.

[0055] Exemplarily, if the first energy of the molten iron in the ladle is within the energy threshold range, the energy state of the ladle is normal; if the first energy of the molten iron in the ladle is not within the energy threshold range, the energy state of the ladle is abnormal.

[0056] It should be noted that classifying the energy state of the ladle into normal and abnormal in the embodiments of the present invention is an exemplary illustration of the embodiments of the present invention. In other embodiments of the present invention, it is classified into different energy states according to different rules, such as classifying the energy state of the ladle into: too low molten iron energy, normal molten iron energy, too high molten iron energy, etc. The present invention is only for illustration and not for limitation.

[0057] S105. Adjust the production operation on the production line where the ladle is located according to the energy state of the ladle so that the energy of the ladle when it reaches the destination point is within the preset energy threshold range.

[0058] Adjusting the production operations on the production line can change the energy of the ladle when it reaches the destination point, so that the energy of the ladle when it reaches the destination point is within the preset energy threshold range, that is, to stabilize the molten iron energy of the ladle and meet the process standards of the mold. There is a corresponding relationship between the production operations corresponding to the energy state of the ladle. According to the energy state of the ladle, select the adjustment method of the corresponding production operation to make the energy of the ladle reach the destination point within the preset energy threshold range.

[0059] The present invention is only for illustration and not for limitation.

[0060] The technical solution of the embodiment of the present invention is to obtain the initial energy and influencing factors of the ladle, where the influencing factor is a factor that affects the energy loss of the molten iron in the ladle on the production line where the ladle is located; predict the loss energy of the ladle based on the influencing factor; subtract the loss energy from the initial energy to predict the first energy of the ladle when it is transported to the destination point; compare the first energy with the preset energy threshold range to obtain the energy state of the ladle; according to the energy state of the ladle, adjust the production operations on the production line where the ladle is located, so that the energy of the ladle when it reaches the destination point is within the preset energy threshold range. The embodiment of the present invention can monitor and predict the energy of the molten iron in the ladle in real time during the transportation process, predict the first energy of the ladle when it is transported to the destination point according to the influence of each influencing factor on the molten iron in the ladle during the transportation process, and accurately guide the production operations on the production line based on this, optimize the transportation process of the ladle, realize the stability of the molten iron energy in the ladle, provide stable molten iron energy for the subsequent steelmaking process, and is conducive to realizing the digitization of molten iron transportation and the process standards of steelmaking production.

[0061] Embodiment Two

[0062] Figure 2 is a flowchart of a method for adjusting the energy of a ladle provided according to Embodiment Two of the present invention. This embodiment is a refinement of each step of the above embodiment. As Figure 2 shown, the method includes:

[0063] S201. Obtain the initial energy and influencing factors of the ladle.

[0064] In some embodiments of the present invention, S201 includes:

[0065] S2011. Obtain the specific heat capacity, liquid surface temperature, purity and weight of the molten iron.

[0066] The initial heat of the molten iron is obtained by multiplying the specific heat capacity, liquid surface temperature, purity and weight of the molten iron. Obtain the specific heat capacity, liquid surface temperature, purity and weight of the molten iron in the ladle for subsequent calculation of the initial heat of the molten iron in the ladle.

[0067] It should be noted that obtaining the specific heat capacity, liquid surface temperature, purity and weight of the molten iron in the embodiments of the present invention is for illustrative purposes. In other embodiments of the present invention, other data for calculating the initial energy may also be obtained. The present invention is only an example and is not limited thereto.

[0068] S2012. Calculate the product of the specific heat capacity, liquid surface temperature, purity and weight of the molten iron to obtain the initial energy of the ladle.

[0069] Multiply the specific heat capacity, liquid surface temperature, purity and weight of the molten iron as the initial energy of the ladle.

[0070] Exemplarily, the specific heat capacity of the molten iron is 0.46×10 3 J / (kg·°C), the liquid surface temperature of the molten iron is 700 °C, the weight of the molten iron is 210 tons, and the purity of the molten iron is 0.95, that is, the iron content in the molten iron accounts for 95%. 0.46×10 3 ×700×210×10 3 ×0.95, and the initial energy of the ladle is obtained as 6.4239×10 10 J.

[0071] It should be noted that the actual values in the embodiments of the present invention are for illustrative purposes. In other embodiments of the present invention, other data may also be used according to the actual situation. The present invention is only an example and is not limited thereto.

[0072] S2013. Obtain the transportation time and the coverage rate of the heat preservation agent as the influencing factors of the ladle.

[0073] Both the transportation time and the coverage rate of the heat preservation agent on the liquid surface of the ladle will affect the energy loss of the molten iron in the ladle. The longer the transportation time and the lower the coverage rate of the heat preservation agent, the faster the energy loss rate of the molten iron in the ladle.

[0074] Obtain the transportation time and the coverage rate of the heat preservation agent as the influencing factors of the ladle for subsequent prediction of the lost energy.

[0075] It should be noted that obtaining the transportation time and the coverage rate of the heat preservation agent as the influencing factors of the ladle in the embodiments of the present invention is for illustrative purposes. In other embodiments of the present invention, other data may also be obtained as the influencing factors of the ladle, such as the time node of adding the heat preservation agent, the amount of the heat preservation agent added, and the current temperature. The present invention is only an example and is not limited thereto.

[0076] S202. Predict the lost energy of the ladle based on the influencing factors.

[0077] In some embodiments of the present invention, S202 includes:

[0078] S2021. Calculate the energy loss coefficient of the ladle based on the influencing factor.

[0079] In some embodiments of the present invention, S2021 includes:

[0080] S211. Determine the current correlation coefficient in the ladle energy-related curve according to the influencing factor.

[0081] The ladle energy-related curve is a curve obtained by fitting experiments using different influencing factors multiple times. According to the actual data of the influencing factor, determine the correlation coefficient corresponding to the current influencing factor in the ladle energy-related curve.

[0082] The embodiments of the present invention are only for illustration and are not limited.

[0083] S212. Multiply the correlation coefficient by the transportation duration to obtain the energy loss coefficient.

[0084] The correlation coefficient is a fixed data value. Multiply the correlation coefficient by the transportation duration to obtain an energy loss coefficient that is proportional to the transportation duration.

[0085] Exemplarily, the determined correlation coefficient is 0.32 and the transportation duration is 0.3 hours. Therefore, the calculated energy loss coefficient is 0.096.

[0086] It should be noted that the actual values in the embodiments of the present invention are for illustrative purposes. In other embodiments of the present invention, other data may also be used according to the actual situation. The present invention is only for illustration and is not limited.

[0087] In some embodiments of the present invention, S2021 further includes:

[0088] S213. Look up the atmospheric influence coefficient of the ladle based on the environmental temperature.

[0089] In addition to the influencing factor affecting the energy loss of the ladle during transportation, the current environmental temperature can also affect the speed of energy loss during transportation. Look up the atmospheric influence coefficient of the ladle based on the current environmental temperature and incorporate the atmospheric influence into the energy loss coefficient.

[0090] Exemplarily, there is a mapping relationship between the environmental temperature and the atmospheric influence coefficient. After knowing the environmental temperature, look up the corresponding atmospheric influence coefficient according to the mapping relationship. If the obtained current atmospheric environmental temperature is 20°C, the corresponding atmospheric influence coefficient is 1.02; if the obtained current atmospheric environmental temperature is above 35°C, the atmospheric influence coefficient is taken as 1.1, where the value range of the atmospheric influence coefficient is between 1.0 and 1.1.

[0091] In other embodiments of the present invention, the season and the atmospheric influence coefficient have a mapping relationship. The corresponding atmospheric influence coefficient can also be queried according to the current season. The embodiments of the present invention are only for illustration and are not limited.

[0092] S214. Multiply the energy loss coefficient by the atmospheric influence coefficient to correct the energy loss coefficient.

[0093] The energy loss coefficient obtained in S212 only considers the influence factors such as the transportation speed and the coverage rate of the heat preservation agent on the energy loss. Multiplying the energy loss coefficient by the atmospheric influence coefficient to correct the energy loss coefficient, and considering the influence of the atmospheric temperature on the energy loss during the transportation process, makes the prediction of the lost energy more accurate and more flexible.

[0094] Exemplarily, the energy loss coefficient is 0.096, and the atmospheric influence coefficient is 1.02. The corrected energy loss coefficient obtained by multiplying 0.096 by 1.02 is 0.09792.

[0095] It should be noted that the actual values in the embodiments of the present invention are for illustrative purposes. In other embodiments of the present invention, other data can also be adopted according to the actual situation. The present invention is only for illustration and is not limited.

[0096] S2022. Multiply the initial energy by the energy loss coefficient to obtain the lost energy of the ladle.

[0097] In some embodiments of the present invention, before S201, it further includes:

[0098] S001. Randomly select the corresponding ladle weight, transportation time, and coverage rate of the heat preservation agent within the preset transportation time range and within the preset coverage rate range of the heat preservation agent for experiments to obtain the corresponding temperature drop difference of the molten iron.

[0099] Since the ladle is filled with molten iron and is in the atmospheric environment, the air temperature, transportation speed, residence time of the ladle at the receiving place, time node of adding the heat preservation agent, and coverage rate of the heat preservation agent during the transportation of the ladle are all changing. It is difficult to obtain the formula through formula calculation and reasoning. In the embodiments of the present invention, the corresponding ladle weight, transportation time, and heat preservation agent are randomly selected within the preset transportation time range and the preset coverage rate range of the heat preservation agent for experiments to obtain the corresponding temperature drop difference of the molten iron.

[0100] Conducting experiments within the specified transportation time range and coverage rate of the heat preservation agent is to simulate the values in the daily production environment, reduce the cost ratio of the experimental test, improve the experimental efficiency, and the experimental data can also be sufficient to obtain the energy-related curve of the ladle.

[0101] The steps and processes for measuring the lost energy are relatively complex. Within a preset transportation time range and within a preset coverage rate range of the heat preservation agent, the corresponding ladle weight, transportation time, and coverage rate of the heat preservation agent are randomly selected for experiments to obtain the corresponding temperature drop difference of the molten iron, making the experimental steps simpler and easier to operate, and further improving the experimental efficiency.

[0102] Exemplarily, the preset transportation time range is 20 to 200 minutes, and the preset coverage rate range of the heat preservation agent is 60% to 100%. During the experiment, it was measured that the transportation time of 180 ladles of molten iron was 0.33 hours, the coverage rate of the heat preservation agent was 100%, and the temperature drop of the molten iron was 7.2 °C; the transportation time of 8 ladles of molten iron was 0.33 hours, the coverage rate of the heat preservation agent was 90%, and the temperature drop of the molten iron was 8.5 °C; the transportation time of 22 ladles of molten iron was 0.33 hours, the coverage rate of the heat preservation agent was 80%, and the temperature drop of the molten iron was 9.6 °C; the transportation time of 220 ladles of molten iron was 0.66 hours, the coverage rate of the heat preservation agent was 100%, and the temperature drop of the molten iron was 12.6 °C; the transportation time of 80 ladles of molten iron was 0.66 hours, the coverage rate of the heat preservation agent was 90%, and the temperature drop of the molten iron was 13.9 °C; the transportation time of 60 ladles of molten iron was 0.66 hours, the coverage rate of the heat preservation agent was 80%, and the temperature drop of the molten iron was 15.6 °C; the transportation time of 36 ladles of molten iron was 1 hour, the coverage rate of the heat preservation agent was 100%, and the temperature drop of the molten iron was 19 °C; the transportation time of 12 ladles of molten iron was 1 hour, the coverage rate of the heat preservation agent was 90%, and the temperature drop of the molten iron was 21 °C; the transportation time of 8 ladles of molten iron was 1 hour, the coverage rate of the heat preservation agent was 80%, and the temperature drop of the molten iron was 22.3 °C.

[0103] It should be noted that the actual values in the embodiments of the present invention are for illustrative purposes. In other embodiments of the present invention, other data can also be used according to the actual situation. The present invention is only an example and is not limited.

[0104] In addition, in other embodiments of the present invention, experiments can also be carried out within the preset transportation time range. For example, experiments can be carried out when the atmospheric environment temperature is between 5 °C and 35 °C. The present invention is only an example and is not limited.

[0105] S002. Convert the temperature drop difference into the corresponding lost energy.

[0106] Multiply the temperature drop difference, the weight of the molten iron, the purity of the molten iron, and the specific heat capacity of the molten iron to obtain the corresponding lost energy, which can more efficiently and conveniently obtain the lost energy corresponding to each test condition in the experiment.

[0107] The embodiments of the present invention are only examples and are not limited.

[0108] S003. Perform correlation processing on the transportation time, the coverage rate of the heat preservation agent, and the corresponding lost energy, and fit the energy-related curve of the ladle.

[0109] Using the transportation time, the covering of the heat preservation agent, and the lost energy obtained after conversion for correlation processing, a ladle energy correlation curve that can reflect the correlation between the lost energy and the transportation time and the covering of the heat preservation agent is fitted.

[0110] It should be noted that the ladle energy correlation curve in the embodiments of the present invention is an exemplary illustration of the correlation curve between the lost energy and the transportation time and the covering of the heat preservation agent. In other embodiments of the present invention, the ladle energy correlation curve may also include the correlation between other influencing factors and the lost energy. The present invention is only for example and is not limited.

[0111] S203. Subtract the lost energy from the initial energy to predict the first energy when the ladle is transported to the destination point.

[0112] S204. Compare the first energy with the preset energy threshold range to obtain the energy state of the ladle.

[0113] In some embodiments of the present invention, S204 further includes:

[0114] S2041. If the first energy is less than the minimum value of the preset energy threshold range, then execute S2042; if the first energy is greater than or equal to the minimum value of the preset energy threshold range and less than or equal to the maximum value of the preset energy threshold range, then execute S2043; if the first energy is greater than the maximum value of the preset energy threshold range, then execute S2044.

[0115] The energy threshold range is a continuous numerical range with a maximum value and a minimum value. If the obtained first energy is less than the minimum value of the energy threshold range, then execute S2042 to determine that the energy state of the ladle is that the molten iron energy is too low. In this state, the molten iron may have poor fluidity and the carbon content of the molten iron will also increase; if the first energy is greater than or equal to the minimum value of the preset energy threshold range and less than or equal to the maximum value of the preset energy threshold range, that is, the first energy is within the preset energy threshold range, then execute S2043 to determine that the energy state of the ladle is that the molten iron energy is normal. At this time, the energy state of the molten iron basically meets the process standard and is within the allowable error range, and has little impact on the finished product of the casting; if the first energy is greater than the maximum value of the preset energy threshold range, then execute S2044 to determine that the energy state of the ladle is that the molten iron energy is too high. In this state, the molten iron may cause rapid loss of the spheroidizing material, low recovery rate of magnesium, which is not conducive to spheroidization, or the oxygen content of the molten iron will increase.

[0116] S2042. Determine that the energy state of the ladle is that the molten iron energy is too low.

[0117] S2043. Determine that the energy state of the ladle is that the molten iron energy is normal.

[0118] S2044. Determine that the energy state of the ladle is that the molten iron energy is too high.

[0119] The embodiments of the present invention are only for illustration and are not limited.

[0120] S205. According to the energy state of the ladle, adjust the production operations on the production line where the ladle is located so that the energy of the ladle when it reaches the target point is within the preset energy threshold range.

[0121] In some embodiments of the present invention, S205 includes:
