[0002] Continuous annealing is relative to hood annealing. Continuous annealing is a production method in which the strip steel continuously passes through the annealing furnace without sealing, and the strip steel is directly coiled without stopping. In production applications, continuous annealing is widely used. Continuous annealing transforms deformed grains into uniform equiaxed grains, eliminates work hardening and residual internal stress, and restores the organization and properties of steel to the state before cold deformation.

[0003] During the continuous annealing process, it is necessary to detect and record abnormalities (such as holes and abnormal thickness) of the steel coils off the continuous annealing unit, especially after the steel coils are cut into sub-coils, the abnormal information of the sub-coils needs to be recorded. However, in the related art, the abnormalities of the cut sub-coils are mainly detected and recorded manually, resulting in problems such as low detection and recording efficiency and high error rate.

[0051] The embodiment of the present application provides a method for detecting abnormalities in slitting sub-rolls, thereby solving the technical problems in the prior art of mainly manually detecting and recording abnormalities in steel coils, which leads to low detection and recording efficiency and high error rate.

[0052] The technical solution of the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0053] In the process of the target continuous annealing production line running, the weld detector on the target continuous annealing production line is controlled to detect the welds appearing on the target continuous annealing production line. When the weld between the previous strip and the current strip is detected, a weld confirmation signal is generated, and the target detection device on the target continuous annealing production line is controlled to detect the actual parameters belonging to the target type on the current strip; when the actual parameters belonging to the target type are abnormal, the distribution position of the abnormal actual parameters on the current strip is recorded; after the current strip is cut into multiple strip sub-rolls, the actual position of the abnormal actual parameters on each strip sub-roll is determined according to the length relationship between the current strip and each strip sub-roll and the distribution position of the abnormal actual parameters on the current strip. It can be seen that the present embodiment avoids the method of mainly manually detecting and recording the abnormality of the steel coil in the related art, and automatically detects and records the abnormality of the slit sub-roll of the continuous annealing unit online, which reduces the labor intensity, improves the detection and recording efficiency and accuracy, and reduces the negative impact on the normal circulation and delivery of the steel coil.

[0054] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0055] First of all, the term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0056] This embodiment provides Figure 1 A method for detecting abnormality in splitting sub-volumes is shown, and the method includes steps S11 to S15.

[0057] Step S11, during the operation of the target continuous annealing production line, controlling the weld detector on the target continuous annealing production line to detect the welds appearing on the target continuous annealing production line;

[0058] Step S12, receiving a weld confirmation signal generated by the weld detector when the weld between the previous steel strip and the current steel strip is detected;

[0059] Step S13, in response to the weld confirmation signal, controlling the target detection device on the target continuous annealing production line to detect the actual parameters of the target type on the current strip;

[0060] Step S14, when there is an abnormality in the actual parameter belonging to the target type, the distribution position of the abnormal actual parameter on the current strip is recorded;

[0061] Step S15, after the current steel strip is cut into multiple steel strip sub-rolls, the actual position of the abnormal actual parameter on each steel strip sub-roll is determined according to the length relationship between the current steel strip and each steel strip sub-roll and the distribution position of the abnormal actual parameter on the current steel strip.

[0062] The present embodiment provides a method for detecting abnormalities in slitting sub-rolls, which can be executed by a host computer of a continuous annealing production line.

[0063] Regarding step S11, during the operation of the target continuous annealing line, the weld inspection instrument on the target continuous annealing line is controlled to inspect the welds appearing on the target continuous annealing line.

[0064] During the operation of the target continuous annealing production line, that is, during the transmission of the strip on the target continuous annealing production line, the weld detector on the target continuous annealing production line is controlled to work so as to detect the welds between the strips running on the target continuous annealing production line.

[0065] Regarding step S12, a weld confirmation signal generated by the weld detector when the weld between the previous steel strip and the current steel strip is detected is received.

[0066] When the weld detector detects a weld, a weld confirmation signal is generated and step S13 is continued.

[0067] In this embodiment, the strip steel before the weld seam is detected is recorded as the previous strip steel, and the strip steel after the weld seam is detected is recorded as the current strip steel. The subsequent steps S13 to S15 in this embodiment are all executed for the current strip steel.

[0068] Regarding step S13, in response to the weld confirmation signal, the target detection equipment on the target continuous annealing line is controlled to detect actual parameters of the target type on the current strip.

[0069] After receiving the weld confirmation signal, the target detection equipment on the target continuous annealing production line can be controlled to detect the actual parameters of the target type on the current strip steel, wherein the target detection equipment includes a thickness gauge and / or a hole gauge.

[0070] Specifically, the thickness gauge on the target continuous annealing production line can be controlled to detect the actual thickness parameters of the current strip steel, and the hole gauge on the target continuous annealing production line can also be controlled to detect the holes in the current strip steel.

[0071] It should be noted that the weld detector that generates the weld confirmation signal should be the weld detector closest to the thickness gauge or hole gauge on the target continuous annealing production line (referred to as the first weld detector). However, since the thickness gauge needs to prepare data such as the coil ID, steel type, thickness, and alloy compensation factor in advance, the thickness gauge needs to be started in advance, and the trigger signal for the early start is generated by the second weld detector that is located before the first weld detector on the target continuous annealing production line.

[0072] That is to say, the weld between the previous strip and the current strip will first be detected by the second weld detector, and then a trigger signal will be generated. The trigger signal is used to control the start of the thickness gauge, so that the thickness gauge can prepare data such as coil ID, steel type, thickness, alloy compensation coefficient, etc. in advance. As the target continuous annealing production line continues to be transported, the weld between the previous strip and the current strip will be detected by the first weld detector, and then a weld confirmation signal will be generated. The weld confirmation signal is used to control the thickness gauge or hole gauge to start normal operation, so as to detect the actual thickness parameters or holes of the current strip.

[0073] When the actual parameters of the current strip steel belonging to the target category do not have abnormalities, it means that the current strip steel is good and does not need to be cut for abnormalities. It can be directly packaged and shipped after being cut into multiple strip steel sub-rolls, thereby reducing manufacturing costs. When the actual parameters of the target category have abnormalities, step S14 is continued.

[0074] Regarding step S14, when there is an abnormality in the actual parameter belonging to the target category, the distribution position of the abnormal actual parameter on the current strip is recorded.

[0075] This embodiment describes step S14 from two aspects: a thickness gauge and a porosity gauge.

[0076]

Thickness Gauge

[0077] When the actual thickness parameter of the current strip exceeds the preset thickness range, it is determined that there is an abnormality in the actual thickness parameter, and the first distribution position of the abnormal thickness position on the current strip is determined based on the first length information between the abnormal thickness position where the abnormal actual thickness parameter is located and the head of the current strip.

[0078] The preset thickness range is set according to the actual situation. When the actual thickness parameter of the current strip exceeds the preset thickness range, it means that there is an abnormality in the actual thickness parameter. Specifically, the thickness abnormality is determined according to the rules based on the thickness curve of the overall detection of the strip. In this embodiment, the position where the actual thickness parameter with the abnormality is located is recorded as the abnormal thickness position, and the first length information between the abnormal thickness position and the head of the current strip is recorded. It should be noted that the actual thickness parameter with the abnormality can be one place or multiple places, which is specifically determined according to the actual situation of the current strip. When there are multiple abnormal thickness positions, the first length information between each abnormal thickness position and the head of the current strip is determined.

[0079] like Figure 2 As shown, it is a schematic diagram of the current strip steel. Figure 2 The left end of the current strip is the tail (i.e. Figure 2 The right end is the head of the current strip (i.e. Figure 2 ). Where X1, X2 and X3 are abnormal thickness positions respectively. The first length information between each abnormal thickness position and the head of the current strip is the length between X1 and the starting point, the length between X2 and the starting point, and the length between X3 and the starting point. That is, the first distribution position of the abnormal thickness position on the current strip is characterized by the first length information.

[0080]

Porosimeter

[0081] When a target hole appears in the current steel strip, it is determined that the current steel strip is abnormal, and a second distribution position of the hole on the current steel strip is determined based on second length information between the target hole and the head of the current steel strip.

[0082] Qualified steel strips have no holes. Holes are defects of steel strips. Therefore, when holes appear in the current steel strip, it means that there is an abnormality at that position. In this embodiment, the hole is recorded as a target hole, and the second length information between the target hole and the head of the current steel strip is recorded. It should be noted that the target hole can be one or more, which is determined according to the actual situation of the current steel strip. When there are multiple target holes, the second length information between each target hole and the head of the current steel strip is determined.

[0083] like Figure 3 As shown, it is a schematic diagram of the current strip steel. Figure 3 The left end of the current strip is the tail (i.e. Figure 3 The right end is the head of the current strip (i.e. Figure 3The second length information between each target hole and the head of the current strip is the length between X1 and the starting point, the length between X2 and the starting point, and the length between X3 and the starting point. That is, the second distribution position of the target hole on the current strip is characterized by the second length information.

[0084] Regarding step S15, after the current steel strip is cut into multiple strip sub-coils, the actual position of the abnormal actual parameters on each strip sub-coil is determined according to the length relationship between the current steel strip and each strip sub-coil and the distribution position of the abnormal actual parameters on the current steel strip.

[0085] This embodiment describes step S15 from two aspects: a thickness gauge and a porosity gauge.

[0086] [Thickness gauge] includes steps S1511 to S1514.

[0087] Step S1511, sorting each strip steel sub-roll according to the direction from the beginning to the end of the current strip steel;

[0088] Step S1512, determining the actual length information between the head and tail of each strip steel sub-roll and the head of the current strip steel;

[0089] Step S1513, determining the actual length ranges corresponding to each strip steel sub-roll and the current strip steel according to the actual length information between the head and tail of each strip steel sub-roll and the head of the current strip steel;

[0090] Step S1514, when the first length information is within the actual length range corresponding to the i-th strip sub-coil, determine the first actual position of the abnormal thickness position on the i-th strip sub-coil according to the actual length range corresponding to the i-th strip sub-coil and the first length information, where i is a positive integer, 0<i≤N, and N is the number of strip sub-coils obtained from the current strip cutting.

[0091] like Figure 2 As shown, the current strip steel is sorted from the starting point to the end point to sort the strip steel sub-rolls. The strip steel sub-rolls from right to left are respectively recorded as the first strip steel sub-roll, the second strip steel sub-roll, and the third strip steel sub-roll.

[0092] Determine the actual length relationship between the head and tail of each strip steel coil and the head of the current strip steel. Figure 2As shown, the head of the first steel strip sub-roll coincides with the head of the current steel strip, so the actual length is 0, the tail of the first steel strip sub-roll is L1 away from the head of the current steel strip, so the actual length is L1, and the actual length range is [0, L1]. The head of the second steel strip sub-roll coincides with the tail of the first steel strip sub-roll (as a dotted line W1), and the tail of the second steel strip sub-roll is L2+L1 away from the head of the current steel strip, so the actual length is L2, and the actual length range is [L1, L2]. The head of the third steel strip sub-roll coincides with the tail of the second steel strip sub-roll (as a dotted line W2), and the tail of the third steel strip sub-roll is L3+L2+L1 away from the head of the current steel strip, so the actual length is L3, and the actual length range is [L2, L3].

[0093] When the first length information corresponding to the abnormal thickness position falls within the range [0, L1], it means that the first strip steel sub-roll has an abnormal thickness position, and then according to the first length information and the range [0, L1], it can be determined that the abnormal thickness position is located at the actual position of the first strip steel sub-roll. When the first length information corresponding to the abnormal thickness position falls within the range [L1, L2], it means that the second strip steel sub-roll has an abnormal thickness position, and then according to the first length information and the range [L1, L2], it can be determined that the abnormal thickness position is located at the actual position of the second strip steel sub-roll. When the first length information corresponding to the abnormal thickness position falls within the range [L2, L3], it means that the third strip steel sub-roll has an abnormal thickness position, and then according to the first length information and the range [L2, L3], it can be determined that the abnormal thickness position is located at the actual position of the third strip steel sub-roll.

[0094] [Pore analyzer] includes steps S1521-S1524.

[0095] Step S1521, sorting each strip steel sub-roll according to the direction from the beginning to the end of the current strip steel;

[0096] Step S1522, determining the actual length information between the head and tail of each strip steel sub-roll and the head of the current strip steel;

[0097] Step S1523, determining the actual length ranges corresponding to each strip steel sub-roll and the current strip steel according to the actual length information between the head and tail of each strip steel sub-roll and the head of the current strip steel;

[0098] Step S1524, when the second length information is within the actual length range corresponding to the j-th strip sub-roll, determine the second actual position of the target hole on the j-th strip sub-roll according to the actual length range corresponding to the j-th strip sub-roll and the second length information, where j is a positive integer, 0<j≤N, and N is the number of strip sub-rolls obtained from the current strip cutting.

[0099] like Figure 3As shown, the current strip steel is sorted from the starting point to the end point to sort the strip steel sub-rolls. The strip steel sub-rolls from right to left are respectively recorded as the first strip steel sub-roll, the second strip steel sub-roll, and the third strip steel sub-roll.

[0100] Determine the actual length relationship between the head and tail of each strip steel coil and the head of the current strip steel. Figure 3 As shown, the head of the first steel strip sub-roll coincides with the head of the current steel strip, so the actual length is 0, the tail of the first steel strip sub-roll is L1 away from the head of the current steel strip, so the actual length is L1, and the actual length range is [0, L1]. The head of the second steel strip sub-roll coincides with the tail of the first steel strip sub-roll (as a dotted line W1), and the tail of the second steel strip sub-roll is L2+L1 away from the head of the current steel strip, so the actual length is L2, and the actual length range is [L1, L2]. The head of the third steel strip sub-roll coincides with the tail of the second steel strip sub-roll (as a dotted line W2), and the tail of the third steel strip sub-roll is L3+L2+L1 away from the head of the current steel strip, so the actual length is L3, and the actual length range is [L2, L3].

[0101] When the second length information corresponding to the target hole falls within the range [0, L1], it means that the second strip steel sub-roll has the target hole, and then the actual position of the target hole in the second strip steel sub-roll can be determined based on the second length information and the range [0, L1]. When the second length information corresponding to the target hole falls within the range [L1, L2], it means that the second strip steel sub-roll has the target hole, and then the actual position of the target hole in the second strip steel sub-roll can be determined based on the second length information and the range [L1, L2]. When the second length information corresponding to the target hole falls within the range [L2, L3], it means that the third strip steel sub-roll has the target hole, and then the actual position of the target hole in the third strip steel sub-roll can be determined based on the second length information and the range [L2, L3].

[0102] After determining the actual position of the abnormal actual parameter on each strip steel sub-roll according to the length relationship between the current strip steel and each strip steel sub-roll and the distribution position of the abnormal actual parameter on the current strip steel, the method further includes:

[0103] Determine whether the absolute value of the difference between the sum of the lengths of the strip steel sub-rolls and the length of the current strip steel is less than or equal to a preset difference threshold;

[0104] When the absolute value of the difference between the sum of the lengths of the strip steel sub-rolls and the length of the current strip steel is less than or equal to the preset difference threshold, the actual position of the abnormal actual parameter on each strip steel sub-roll is recorded;

[0105] When the absolute value of the difference between the sum of the lengths of the strip sub-rolls and the length of the current strip is greater than a preset difference threshold, an abnormal alarm signal is generated.

[0106] That is to judge Figure 2 and Figure 3 Whether |L1+L2+L3-Ltotal| is less than or equal to the preset difference threshold value P. When |L1+L2+L3-Ltotal|≤P, it means that the error is within a reasonable range, and the position of the abnormal actual parameters detected by steps S11-S15 is reasonable, and then the actual position of the abnormal actual parameters on each strip sub-coil can be recorded. When |L1+L2+L3-Ltotal|>P, it means that the error is not within a reasonable range, and the position of the abnormal actual parameters detected by steps S11-S15 is unreasonable, and then an abnormal alarm signal can be generated to remind relevant staff to re-record manually. The preset difference threshold value P can be set according to actual conditions, for example 5≤P≤15.

[0107] In summary, in the process of the target continuous annealing production line running, the weld detector on the target continuous annealing production line is controlled to detect the welds appearing on the target continuous annealing production line. When the weld between the previous strip and the current strip is detected, a weld confirmation signal is generated, and the target detection device on the target continuous annealing production line is controlled to detect the actual parameters belonging to the target type on the current strip; when the actual parameters belonging to the target type are abnormal, the distribution position of the abnormal actual parameters on the current strip is recorded; after the current strip is cut into multiple strip sub-rolls, the actual position of the abnormal actual parameters on each strip sub-roll is determined according to the length relationship between the current strip and each strip sub-roll and the distribution position of the abnormal actual parameters on the current strip. It can be seen that the present embodiment avoids the method of mainly manually detecting and recording the abnormality of the steel coil in the related art, and automatically detects and records the abnormality of the slit sub-roll of the continuous annealing unit online, which reduces the labor intensity, improves the detection and recording efficiency and accuracy, and reduces the negative impact on the normal circulation and delivery of the steel coil.

[0108] Based on the same inventive concept, this embodiment provides Figure 4 A device for detecting abnormality in slitting sub-rolls is shown, the device comprising:
