Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of blast furnace operation, in particular to a color value recognition device, a furnace condition stabilizing method, equipment and a storage medium. BACKGROUND

[0002] At present, the stable operation of a blast furnace refers to the uniformity of the descent of the furnace charge and the ascent of the gas flow in the furnace, the stability of the furnace temperature and the stability of the pig iron quality. Due to the closed process of blast furnace ironmaking and the harsh conditions such as high pressure and high temperature in the internal environment, it is difficult to accurately detect the process parameters in real time online. Therefore, the blast furnace operating condition stability is generally represented by indirect parameters such as air volume, air pressure, material speed and top temperature. There are many controversies in the industry, and there is no consistent and recognized technical index. Due to the difficulty in accurately detecting the actual blast furnace smelting process parameters in real time, the length of the blast furnace is generally determined by the experience of the operator, combined with the above indirect parameters and the actual blast furnace operation state observed by the operator, such as the flame at the tuyere and the iron flower, and the blast furnace operating condition stability is determined by the operator, which makes the coordination between the teams in the blast furnace production operation poor. In addition, this manual experience operation mode is subjective and relatively rough, and requires a high level of experience in blast furnace operation.

[0003] At present, the blast furnace operating condition stability is generally represented by indirect parameters, such as the ratio between the change rate of the material weight and the average change rate of the maximum temperature difference of the top gas, and the change rate of the top temperature corresponding to the material time. All of these are indirect parameters such as material speed and top temperature. There are still controversies in the actual implementation process, and the blast furnace production operation still needs to be implemented by the operator's visual judgment.

[0004] In summary, the blast furnace operating condition stability is determined by indirect parameters in the prior art, which has the problems of non-uniform index and large error. In addition, the manual visual judgment is subjective and relatively rough. Therefore, how to provide a solution to the above technical problems is a problem that needs to be solved by those skilled in the art at present. SUMMARY

[0042] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0043] At present, the stable and smooth operation of a blast furnace refers to that the descent of the furnace charge and the ascent of the gas flow in the furnace are uniform, the furnace temperature is sufficient and stable, and the quality of the pig iron is stable. Since the blast furnace ironmaking process is closed, the internal operating environment is high pressure and high temperature, and the like, and the process parameters are difficult to be accurately detected in real time, the blast furnace condition stability can be represented by indirect parameters such as the air volume, the air pressure, the material speed, and the top temperature, and there are many controversies in the industry and even in the same enterprise, and there is a lack of a consistent and recognized technical index. Since the actual blast furnace smelting process parameters are difficult to be accurately detected in real time, at present, the length of the blast furnace is generally determined according to the experience of the operator, combined with the above indirect parameters and the visual observation of the actual blast furnace operating process, and the blast furnace condition stability is manually judged, so that the coordination among the shifts of the blast furnace production operation is poor, and such a manual experience operation mode is subjective and relatively rough, and requires a high level of experience of the operator of the blast furnace. That is, the blast furnace condition stability is judged by indirect parameters, which has problems such as non-uniform index and large error, and the manual visual judgment is subjective and relatively rough. Therefore, the present application provides a color value recognition device, which can solve the problems such as non-uniform index and large error in the judgment of the blast furnace condition stability by indirect parameters, and subjective and relatively rough manual visual judgment, so as to intuitively and accurately judge the blast furnace condition stability.

[0044] The embodiment of the present application discloses a color value recognition device, as shown in the figure, which comprises: Figure 1

[0045] A molten iron sampler A1 is used to obtain molten iron.

[0046] In the embodiment, the molten iron sampler A1 is composed of a sampling rod 1 and a sampling spoon 2; as shown in the figure, the sampling rod 1 is used to obtain the molten iron, and the sampling spoon 2 is used to collect the molten iron. Figure 2 ​As shown, the sampling rod 1 is a steel tube rod made of hard heat-resistant steel tube, one end of the sampling rod 1 is wrapped with hard heat-resistant rubber material as a hand handle 3, the other end of the sampling rod is welded with the sampling spoon 2, and the sampling spoon 2 is made of hard heat-resistant alloy. It should be pointed out that the size of the molten iron sampler A1 can be determined according to the actual space size in front of the furnace, and the size of the sampling rod 1 can be 3000mm-4000mm, and the size of the sampling spoon 2 can be 125cm 3 -1000cm 3 .

[0047] The standard sample box 6 is used to contain the molten iron obtained by the molten iron sampler;

[0048] In this embodiment, the standard sample box installed under the semi-closed camera box is a sample box 6 with an open top and tightly closed box edges 4 and box bottom 5, and the standard sample box 6 is made of heat-resistant material. As shown in Figure 3 The bottom is paved with refractory bricks as the box bottom 5, the four surrounding box edges 4 are tightly closed to prevent molten iron from overflowing, and the upper opening is convenient for pouring molten iron and system value taking, and the size of the standard sample box can be 125cm 3 .

[0049] The semi-closed camera box A2 is used to collect the molten iron level image of the molten iron in the standard sample box through the fixed camera in the semi-closed camera box;

[0050] In this embodiment, the semi-closed camera box A2 is composed of a semi-closed box body 7, a standard lamp 8 and a fixed camera 9; the semi-closed box body 7 is a lower opening box body made of hard heat-resistant material; the fixed camera 9 is a high-definition camera fixedly installed on the upper side inside the semi-closed box body; and the standard lamp 8 is a high-brightness heat-resistant lamp fixedly installed on the upper side inside the semi-closed box body. For example, as shown in Figure 4 A semi-closed box body 7 of 5.5m×1.5m×800mm is made of φ3mm steel plate, three sides are closed, the lower opening side faces the upper surface of the molten iron in the standard sample box 6, a high-definition camera 9 is fixedly installed on the upper side in the semi-closed box, the angle is fixed, that is, perpendicular and fixed distance, the high-definition camera 9 collects the molten iron level image in the standard sample box, and 8 groups of LED high-brightness heat-resistant lamps 8 are fixedly installed on the upper side in the semi-closed box, the light directly irradiates the molten iron level in the standard sample box 6 to ensure that the environmental brightness is relatively stable.

[0051] The strong wind cooling system 10 installed at the preset positions inside and outside the semi-closed camera box is used to reduce the environmental temperature of the semi-closed camera box;

[0052] In this embodiment, the strong wind cooling system 10 uses high-pressure air as a cooling source and is installed at appropriate positions inside and outside the semi-closed box, thereby reducing the ambient temperature of the semi-closed camera box A3 and ensuring the cleanliness of the semi-closed camera box A3, especially the cleanliness of the high-definition camera therein.

[0053] The color value recognition system A3 installed in the blast furnace master control microcomputer 11 is used to extract the color value of the molten iron in the molten iron surface image and monitor the time when the color value of the molten iron reaches a standard color value to determine the stability of the blast furnace condition based on the sampling start time of the molten iron and the time when the standard color value is reached; the standard color value represents the average value of the color value when the color of the molten iron in the standard sample box of the previous n furnaces changes to a dark color.

[0054] It can be understood that the color value recognition system is installed in the blast furnace master control microcomputer, extracts the color value of the collected molten iron surface image, monitors the time when the standard color value is reached, and calculates the stability of the blast furnace condition at the blast furnace by analogy. Among them, the standard color value is the color value when the color of the molten iron changes to a dark color. It should be pointed out that in addition to using the average value of the color value when the color of the molten iron in the standard sample box of the previous n furnaces changes to a dark color to represent the standard color value, the standard color value R, G, B or H, S, V, etc. can also be manually inputted by human intervention. And the value of n can be set to any one of 5 to 30. For example, the average value of the dark color value of the molten iron in the standard sample box of 30 furnaces is taken as the standard color value, or the standard color value H is manually inputted, and when the furnace condition appears to be a phased abnormal fluctuation, the upper limit of the furnace temperature is controlled, and the standard color value is determined according to the actual experience value.

[0055] It can be seen that in the embodiments of the present application, through the color value analysis of the molten iron sampling at the blast furnace, the problems of non-uniformity of indicators, large error, subjective and relatively rough manual visual judgment, etc. in judging the stability of the blast furnace condition by indirect parameters are solved, the stability of the blast furnace condition can be directly and accurately judged, thereby providing a scientific basis for the overall production operation of the blast furnace, providing a convenient and intuitive technical index for the scientific evaluation of the stability of the blast furnace condition, and greatly improving the skill level and efficiency of the operation at the blast furnace.

[0056] The embodiment of the present application discloses a furnace condition stability method, as shown in Figure 5 The color value recognition system applied in the color value recognition device is used.

[0057] Step S11: determining the difference between the sampling start time when the molten iron is obtained and the time when the standard color value is reached to obtain a standard color value time difference.

[0058] In the embodiment, the color value recognition system monitors the time when the color value of the molten iron reaches the standard color value, i.e., the time when the standard color value is reached, and then determines the standard color value time difference according to the recorded sampling start time of the molten iron and the time when the standard color value is reached. For example, the standard color value time difference T n = time when the standard color value is reached - sampling start time.

[0059] Step S12: determining the blast furnace condition stability value based on the standard color value time difference.

[0060] In the embodiment, after determining the difference between the sampling start time of the molten iron and the time when the standard color value is reached to obtain the standard color value time difference, the blast furnace condition stability value can be directly determined based on the standard color value time difference, that is, the blast furnace condition stability can be directly and accurately determined by analyzing the color value of the iron sample taken at the blast furnace front, and specifically, the difference between the standard color value time difference of the previous n furnaces and the standard color value time difference of the previous n-1 furnaces is determined, the ratio between the difference and the average of the standard color value time difference of the previous m furnaces is determined, and the percentage of the sum of the preset value and the ratio is determined as the blast furnace condition stability value. For example, the blast furnace condition stability value W n = [1 + (standard color value time T n - standard color value time T n-1 ) / average of the standard color value time of the previous m furnaces] x 100%, wherein the value of n can be set to any value in the range of 5 to 30, and the value of m can be set to any value in the range of 8 to 72 according to actual production conditions.

[0061] Step S13: determining the stability of the blast furnace condition according to the blast furnace condition stability value, and triggering the execution of the stable condition operation corresponding to the blast furnace condition stability.

[0062] It should be noted that the reasonable threshold of the blast furnace condition stability at the blast furnace front can be set according to actual production, and any value in the range of 105% to 120% can be determined as the preset upper stability threshold, any value in the range of 110% to 140% can be determined as the preset upper upper stability threshold, any value in the range of 80% to 95% can be determined as the preset lower stability threshold, and any value in the range of 60% to 90% can be determined as the preset lower lower stability threshold.

[0063] In this embodiment, after the blast furnace condition stability value is calculated, the stability of the blast furnace condition is determined according to the blast furnace condition stability value, and the stable condition operation corresponding to the blast furnace condition stability is triggered. For example, the preset stability upper limit threshold of the blast furnace condition is set to 120%, the preset stability upper limit threshold is set to 110%, the preset stability lower limit threshold is set to 90%, and the preset stability lower limit threshold is set to 80%. If the blast furnace condition stability value is less than the preset stability upper limit threshold and greater than the preset stability lower limit threshold, it is determined that the stability of the blast furnace condition is good, and the stable condition operation of keeping good is maintained. That is, the blast furnace condition stability value is within the reasonable threshold range, that is, 90% < W n <110%, which indicates that the current blast furnace condition stability is good, and as long as the stable condition operation of keeping good is continued, the blast furnace condition stability is good. If the blast furnace condition stability value is less than or equal to the preset stability lower limit threshold and greater than the preset stability lower limit threshold, it is determined that the stability of the blast furnace condition is deviated downward, and the stable condition operation of increasing the furnace temperature is triggered. That is, the blast furnace condition stability value is lower than the lower limit of the reasonable threshold, that is, 80% < W n ≤90%, which indicates that the current blast furnace condition stability is deviated downward, and the stable condition operation of increasing the furnace temperature needs to be performed. If the blast furnace condition stability value is less than or equal to the preset stability lower limit threshold, it is determined that the stability of the blast furnace condition is deviated downward too much, and the stable condition operation corresponding to the stability deviated downward too much is triggered. That is, the blast furnace condition stability value is lower than the lower limit of the reasonable threshold, that is, W n ≤80%, which indicates that the current blast furnace condition stability is deviated downward too much, and the stable condition operation of increasing the fuel ratio and reducing the tapping needs to be performed. If the blast furnace condition stability value is less than the preset stability upper limit threshold and greater than or equal to the preset stability upper limit threshold, it is determined that the stability of the blast furnace condition is deviated upward, and the stable condition operation corresponding to the stability deviated upward is triggered. That is, the blast furnace condition stability value is higher than the upper limit of the reasonable threshold, that is, 110% ≤ W n <120%, which indicates that the current blast furnace condition stability is deviated upward, and the analysis and processing of the indirect parameters such as the air volume, the air pressure, the material speed, and the top temperature need to be performed in time. If the blast furnace condition is stable and in order, the low-silicon smelting operation is appropriately performed on the basis of the stable condition. If the blast furnace condition appears a stage abnormal fluctuation, the furnace temperature upper limit control is performed, and the furnace temperature operation is continued to be performed. If the blast furnace condition stability value is greater than the preset stability upper limit threshold, it is determined that the stability of the blast furnace condition is deviated upward too much, and the stable condition operation corresponding to the stability deviated upward too much is triggered. That is, the blast furnace condition stability value is higher than the upper limit of the reasonable threshold, that is, W n≥120% indicates that the current blast furnace stability is too high, and needs to be analyzed and processed in time in combination with the indirect parameters such as air volume, air pressure, material speed, top temperature, etc. If the blast furnace is stable and smooth, then low-silicon smelting operation is appropriately performed on the basis of stable blast furnace; if the blast furnace appears stage abnormal fluctuation, then the upper limit control of blast furnace temperature is continued.

[0064] It can be seen that, in the embodiment of the application, through the sampling color value analysis of the blast furnace tap hole, the problems of non-uniform index, large error, subjective and relatively rough manual visual judgment, etc. in the judgment of blast furnace stability by indirect parameters are solved, the blast furnace stability can be directly and accurately judged, thereby providing a scientific basis for the overall production operation of the blast furnace, and providing a convenient and intuitive technical index for the scientific evaluation of the blast furnace stability, and greatly improving the skill level and operation efficiency of the blast furnace operation.

[0065] For example, a standard sample box made of refractory bricks is placed under a semi-closed camera box, the strong cold valve, the fixed camera in the semi-closed camera box and the standard lamp are turned on, the color value recognition system in the main control microcomputer of the blast furnace is inputted with the standard color value, or the average color value of the previous 24 furnaces is automatically calculated as the standard color value, and the related stability threshold is set, the color value recognition system is started and runs, then the molten iron sampler is used to pour the molten iron from the iron runner into the standard sample box, the color value recognition system runs, if it is identified and judged that the current blast furnace stability is good, such as case 1 in Table 1, then it is continued; if it is identified and judged that the current blast furnace stability is lower, such as case 2 in Table 1, then the blast furnace temperature is raised to stabilize the blast furnace; if it is identified and judged that the current blast furnace stability is too low, such as case 3 in Table 1, then the stable blast furnace operation such as increasing the fuel ratio and reducing the tapping is timely performed; if it is identified and judged that the current blast furnace stability is too high, such as case 4 in Table 1, then the indirect parameters such as air volume, air pressure, material speed, top temperature, etc. are analyzed and processed in time, if the blast furnace is smooth, then low-silicon smelting operation is appropriately performed, if the blast furnace is stage fluctuation, then the upper limit control of the blast furnace temperature is continued; if it is identified and judged that the current blast furnace stability is too high, such as case 5 in Table 1, then the indirect parameters such as air volume, air pressure, material speed, top temperature, etc. are analyzed and processed in time, if the blast furnace is smooth, then low-silicon and production-increasing smelting operation is appropriately performed on the basis of stable blast furnace, if the blast furnace is stage fluctuation, then the upper limit control of the blast furnace temperature is continued.
