DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.
[0019] According to an embodiment of the present invention, an embodiment of a fault detection method for the tundish slagging process is provided. It should be noted that the steps shown in the flowchart of the drawings can be executed in a computer system such as a set of computer-executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.
[0020] This embodiment provides a method for fault detection in the process of slag entrainment in the tundish of continuous casting, as Figure 1 shown, the method includes the following steps: S101. Obtain the slag entrainment signal value and record the number of times the corresponding slag entrainment signal value appears.
[0021] Specifically, the slag entrainment signal value is a coil acquisition value used to represent the amount of molten slag in the ladle. The number of times the corresponding slag entrainment signal value appears can be expressed as, for example, when the slag entrainment signal value is 20, the number of appearances is 4 times, and when the slag entrainment signal value is 5, the number of appearances is 3 times, etc.
[0022] S102. In response to the slag entrainment signal value reaching a preset value, send an opening signal to start the slag entrainment process of the current round.
[0023] Specifically, the preset value refers to the set limit value of the slag entrainment signal. When the slag entrainment signal reaches the set limit value, the opening signal sent refers to opening the baffle for controlling the pouring of molten steel. During the slag entrainment process of each round, the weight of the ladle continuously decreases due to the pouring of molten steel in the ladle, for example, from 100 tons to 20 tons.
[0024] S103. In response to the slag entrainment signal value reaching a first threshold and the number of times reaching a second threshold corresponding to the first threshold, determine that there is a slag entrainment fault in the slag entrainment process of the current round.
[0025] Specifically, the first threshold includes a first upper limit threshold and a first lower limit threshold. Correspondingly, the second thresholds corresponding to the first threshold respectively include a second upper limit threshold and a second lower limit threshold. Among them, the first upper limit threshold, the first lower limit threshold, the second upper limit threshold, and the second lower limit threshold can be set according to the actual working conditions, and this embodiment does not make specific limitations on this.
[0026] Specifically, the slag entrainment signal value reaching the first threshold means that the slag entrainment signal value exceeds the first upper limit threshold or reaches the first lower limit threshold, and the number of times reaching the second threshold corresponding to the first threshold means that the number of times the corresponding slag entrainment signal value appears exceeds the second upper limit threshold or the second lower limit threshold.
[0027] The present invention provides a method, device, equipment, and medium for fault detection in the process of ladle slag falling during continuous casting. This method obtains the slag falling signal value and records the number of times the corresponding slag falling signal value appears. When the slag falling signal reaches a preset value, the slag falling process of the current round is started, and it is determined that there is a slag falling fault in the slag falling process of the current round by using the slag falling signal and the number reaching the first threshold and the second threshold respectively. In this process, the slag falling signal value is used as the basis for judging to start the slag falling process of the current round, and the slag falling signal and the number of times corresponding to the slag falling signal value are used as the basis for determining that there is a slag falling fault in the slag falling process of the current round, so that when the slag falling signal and the number reach the first threshold and the second threshold respectively in the slag falling process of the current round, it is determined that there is a slag falling fault in the slag falling process of the current round, thereby completing the fault detection of the slag falling process and avoiding the occurrence of production abnormalities caused by slag falling faults.
[0028] In an alternative embodiment, in response to the slag falling signal value reaching the first threshold and the number reaching the second threshold corresponding to the first threshold, determining that there is a slag falling fault in the slag falling process of the current round includes: In response to the slag falling signal value exceeding the first upper limit threshold and the number reaching the second upper limit threshold corresponding to the first upper limit threshold, it is determined that there is a slag falling fault in the slag falling process of the current round.
[0029] Specifically, the slag falling signal value exceeding the first upper limit threshold means that the obtained slag falling signal value is greater than the set first upper limit threshold, and the number reaching the second upper limit threshold corresponding to the first upper limit threshold means that the number of times the slag falling signal value is greater than the set first upper limit threshold is greater than or equal to the second upper limit threshold. Among them, the first upper limit threshold can be 30, 25 or other values, and usually a positive integer is selected as the first upper limit threshold, such as 30; the second upper limit threshold can be 3, 4 or other values, and usually a positive integer is selected as the second upper limit threshold, such as 3. It can be specifically set according to the actual working conditions, and this embodiment does not make specific limitations on this.
[0030] In an alternative embodiment, in response to the slag falling signal value reaching the first threshold and the number reaching the second threshold corresponding to the first threshold, determining that there is a slag falling fault in the slag falling process of the current round includes: In response to the slag falling signal value reaching the first lower limit threshold and the number reaching the second lower limit threshold corresponding to the first lower limit threshold, it is determined that there is a slag falling fault in the slag falling process of the current round.
[0031] Specifically, the ladle slag signal value reaching the first lower limit threshold means that the obtained ladle slag signal value is equal to or less than the set first lower limit threshold, and the number of times reaching the second lower limit threshold corresponding to the first lower limit threshold means that the number of times the ladle slag signal value is equal to or less than the set first lower limit threshold is greater than or equal to the second lower limit threshold. Here, the first lower limit threshold can be 0, 1, or other values, and usually an integer is selected as the first lower limit threshold, such as 0; the second lower limit threshold can be 5, 6, or other values, and usually a positive integer is selected as the second lower limit threshold, such as 5. Specifically, it can be set according to the actual working conditions, and this embodiment does not make specific limitations in this regard.
[0032] In an alternative embodiment, the method further includes: In response to there being no ladle slag fault during the ladle slag process of the current round, send a shutter signal to end the ladle slag process of the current round.
[0033] Specifically, when there is no ladle slag fault during the ladle slag process of the current round, the sent shutter signal means controlling the shutter for molten steel pouring to close, ending the ladle slag process of the current round until the ladle slag process of the next round. It should be understood that there are multiple rounds of ladle slag processes in the overall ladle slag process.
[0034] In an alternative embodiment, after ending the ladle slag process of the current round, the method further includes: Obtain the weight of the tundish in real time; record and update the weight of the tundish corresponding to the end of the ladle slag process of the current round.
[0035] Specifically, since there are multiple rounds of ladle slag processes in the overall ladle slag process, when there is no ladle slag fault during the ladle slag process of the current round, record and update the weight of the tundish corresponding to the end of the ladle slag process of the current round as the gross weight before the start of the ladle slag process of the next round. For example, if the weight of the tundish corresponding to the end of the first-round ladle slag process is a, then the gross weight of the tundish before the start of the second round is a.
[0036] In an alternative embodiment, the method further includes: In response to there being a ladle slag fault during the ladle slag process of the current round, do not update the weight of the tundish.
[0037] Specifically, since there are multiple rounds of ladle slag processes in the overall ladle slag process, when there is a ladle slag fault during the ladle slag process of the current round, do not update the weight of the tundish. For example, if the weight of the tundish corresponding to the end of the first-round ladle slag process is a, but there is a ladle slag fault during the ladle slag process of the second round and the weight of the tundish is not updated, then the gross weight of the tundish before the start of the third round is a.
[0038] In an alternative embodiment, the method further includes: Generate a slagging fault warning message in response to a slagging fault during the slagging process of the current round; send the slagging fault warning message based on a preset path.
[0039] Specifically, sending the slagging fault warning message based on a preset path includes voice broadcasting the slagging fault warning message on the equipment at a preset point and sending a slagging fault information prompt to a preset relevant person in charge.
