In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
First, the term "and/or" appearing herein is merely an association relationship describing associated objects, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.
The strip steel treatment system provided by the embodiment of the invention can be arranged at the upstream of the finishing unit, so that the finishing unit utilizes the comprehensive treatment data to comprehensively judge the quality of strip steel. Of course, the system can also be arranged on a production line without finishing units, and only outputs comprehensive treatment data, thereby providing treatment comments for technicians responsible for the production line.
Referring next to fig. 1, a strip steel handling system in an embodiment of the invention includes: a defect position determining unit 101, configured to acquire and process data, size data, and defect data of the strip steel during the rolling process, so as to obtain defect position data of the strip steel; the coil separating position determining unit 102 is configured to pre-roll the strip steel based on a preset coil separating requirement and defect position data, so as to obtain coil separating result data; and a strip steel quality judging unit 103 for acquiring the rolling result data and processing the rolling result data based on a preset judging condition to obtain comprehensive treatment data provided to the finishing unit so that the finishing unit judges the strip steel quality by using the comprehensive treatment data.
In the embodiment of the present invention, a defect detector (not shown) may be disposed upstream of the production line where the defect position determining unit 101 is located, where the defect detector is configured to detect various defects existing on the strip steel, record the positions of the defects to obtain defect data, and then feed back the defect data to the defect position determining unit 101 at the downstream, where the defect detector may be one or more of a thickness gauge, a core loss gauge, a hole gauge, and a edge drop gauge.
In order to obtain the process data of the strip steel in the rolling process, a process recorder (not shown) may be arranged at the upstream of the production line where the defect position determining unit 101 is located, the process recorder is used for recording and feeding back the process data to the defect position determining unit 101, the process data may be an uncoiling mode, a coiling mode, a head-to-tail turning, a steel grade density, a strip steel number and a rolling mill set through which the strip steel passes, and the rolling mill set through which the strip steel passes may be an acid rolling mill set, an annealing first set, an annealing second set and the like; and in order to obtain the dimension data of the strip steel during the rolling process, a dimension measurer (not shown) may be disposed upstream of the production line where the defect position determining unit 101 is located, and the dimension measurer is used for recording and feeding back the dimension data of the strip steel to the defect position determining unit 101, where the dimension data may be the length, thickness, width, and the like of the strip steel.
In order to improve the reliability of the feedback data of the instrument, the instrument can be checked, for example, a dimension measurer is used for measuring the standard strip steel, and then whether the difference between the measured value and the length of the standard strip steel is smaller than 1-2 meters is calculated and judged.
For the density of the steel grade, since the densities of the steel grades are different, the accurate densities of the steel grades are required to be calculated through weighing, the theoretical calculation result of the densities is consistent with the actual weight result, and the density of the steel grade is obtained by dividing the total weight of the strip steel by the volume of the strip steel, wherein the strip steel is subjected to trimming treatment at a finishing unit, and therefore, when the volume of the strip steel is calculated, an allowable tolerance range, such as a tolerance of +/-0.5 mm-1 mm, can be set for the width of the strip steel based on the preset width.
In a specific implementation process, the defect position determining unit 101 obtains process data, size data and defect data of the strip steel in the rolling process, and the process data of the strip steel can be processed in the following manner:
In the first mode, for the process data, the coiling mode of the strip steel in the process data is taken as an example, the upper surface of the strip steel can be represented by the number "1", the turn-over of the strip steel can be represented by the number "-1", if the coiling mode is "1" after the strip steel passes through the acid rolling mill, the coiling mode is changed to "-1" after the strip steel passes through the annealing first mill, and the coiling mode is changed to "-1" after the strip steel passes through the annealing second mill, the product of the numbers can represent the final mode of strip steel coiling, namely, 1× -1=1, that is, the final mode of strip steel coiling is the upper surface.
In the second mode, for the process data, the head-tail turning of the strip steel in the process data is taken as an example, the positive direction of the strip steel can be represented by the number "1", the turning of the strip steel can be represented by the number "-1", if the strip steel passes through the acid rolling mill, the coiling mode is "1", after passing through the annealing first mill, the coiling mode is changed to "-1", after passing through the annealing second mill, the coiling mode is changed to "-1", and the sum of the numbers can represent the final mode of the turning of the strip steel, namely, 1+ (-1) +(-1) =1, that is, the final mode of the turning of the strip steel is the positive direction, that is, no turning occurs.
After processing the technical data of the strip steel, combining the size data and the defect data, the defect position data of the strip steel can be obtained.
For example, if the number of the strip is: 192187540, the strip steel needs to sequentially pass through an acid rolling unit, an annealing unit and a finishing unit, a defect detector records a defect A at the acid rolling unit, the defect A is positioned on the upper surface of the strip steel, the distance between the starting position of the defect A and an acid rolling head is A 1, the distance between the ending position of the defect A and the acid rolling head is A 2, … … the defect A passes through 3 head-tail turns before reaching the finishing unit, and a defect position determining unit 101 processes the process data, the size data and the defect data to obtain that the strip steel does not turn head-tail and turn up and down, and the position of the defect A is in the positive direction and is positioned on the upper surface of the strip steel.
The distance of the start position of the defect a from the finishing head can be obtained by the following formula:
Wherein S 1 is the distance between the starting position of the defect A and the finishing head, A 1 is the distance between the starting position of the defect A and the acid rolling head, T t is the strip tail cutting length of the strip steel in the annealing unit, H j is the strip head cutting length of the strip steel in the finishing unit, L j is the strip steel length in the finishing unit, and L s is the strip steel length in the acid rolling unit;
the distance between the end position of defect a and the finishing head can be found by the following formula:
Wherein S 2 is the distance between the end position of the defect A and the finishing head, A 1 is the distance between the end position of the defect A and the acid rolling head, T t is the strip tail cutting length of the strip steel in the annealing unit, H j is the strip head cutting length of the strip steel in the finishing unit, L j is the strip steel length in the finishing unit, and L s is the strip steel length in the acid rolling unit.
In a specific implementation process, the roll position determining unit 102 is specifically configured to: determining a pre-rolling position of the strip steel based on a preset rolling requirement so as to pre-roll the strip steel into N coils of sub-strip steel, wherein N is a positive integer greater than or equal to 1; and judging the N coils of sub-strip steel based on the defect position data to obtain the coil separating result data used for representing the position information of the N coils of sub-strip steel and a first judging result, wherein the first judging result represents whether the sub-strip steel is qualified or not.
For the preset scroll requirement, specifically, the preset scroll requirement may include: the minimum weight requirement per coil of strip steel and the packaging requirement, wherein the packaging requirement can be that the weight of each coil of strip steel is more than X tons and less than Y tons.
Specifically, based on preset coiling requirements, the coiling length of each coil of sub-strip steel can be calculated by combining preset density, length, width and thickness of the strip steel, the pre-coiling position of the strip steel can be determined, the strip steel is pre-coiled into N coils of sub-strip steel, then the N coils of sub-strip steel are judged based on defect position data, the positions of defects on the strip steel are recorded by the defect position data, the distance between the defects can be determined, when the strip steel is pre-coiled, the part with concentrated defects is divided into one coil, and the other coils of sub-strip steel can not have defects, so that coiling result data used for representing the position information of the N coils of sub-strip steel and a first judgment result is obtained, wherein the first judgment result represents whether the sub-strip steel is qualified or not.
For example, referring to fig. 2, if the minimum weight requirement of each coil of the strip steel is 3 tons, the defect position data recorded on the strip steel includes: a and B, and a pre-winding M 1 between defect a and defect B, wherein the length of defect a is the distance between a 1 and a 2, and the length of defect B is the distance between B 1 and B 2; the following determination can be performed on the strip steel to obtain corresponding rolling result data:
(1) If the weight between the defect A and the defect B is more than 0 ton and less than 3 tons, the defect A and the defect B are unified into a coil of sub-band steel, and the judgment result is that: the coiled strip steel is unqualified.
(2) If the weight between the defect A and the defect B is equal to 3 tons and less than X tons, the defect A and the defect B are unified into a coil of sub-band steel, and the judgment result is that: the coiled strip steel is qualified.
(3) If the weight between the defect A and the defect B is equal to X tons and less than Y tons, the strip steel between the A 2 and the B 1 is pre-divided into a coil of sub-strip steel, and the judgment result is that: the coiled strip steel is qualified.
(4) If the weight between the defect A and the defect B is more than or equal to Y tons and less than X+X tons, the strip steel between A 2 and M 1 is pre-divided into a first sub-strip steel and the strip steel between M 1 and B 1 is pre-divided into a second sub-strip steel according to the maximum weight of each coil of the strip steel as Y tons, wherein the judgment result of the first sub-strip steel is as follows: the coiled strip steel is qualified; and the second sub-strip steel is re-judged according to the judging mode.

(6) If the weight between the defect A and the defect B is large is equal to or less than Y+Y tons and less than X+X+X tons, according to the maximum weight of each coil of strip steel being Y tons, the strip steel is pre-divided into two coils of strip steel with the same weight, pre-dividing the strip steel between M 1 and B 1 into a third sub-strip steel, wherein the judging result of the two coils of sub-strip steel between A 2 and M 1 is as follows: qualified; and the third sub-strip steel is re-judged according to the judging mode.
(7) And if the weight between the defect A and the defect B is more than or equal to X+X … … +X tons and less than Y+Y … … +Y tons, analogizing is performed according to the method, and judging results are respectively made.
If the whole coiled steel is not recorded with defects, each coiled strip steel after pre-coiling is qualified; if a plurality of defects exist on the strip steel, such as a defect A, a defect B and a defect C exist on the strip steel, when the strip steel is pre-rolled, after the pre-rolling position between the defect A and the defect B is determined, the pre-rolling position between the defect B and the defect C is determined in sequence, and so on until all the sub-rolling position data are obtained.
In addition, after the band steel meets the minimum weight requirement, if the minimum weight required by the package is X tons and the maximum weight is Y tons, if the weight of each coil of band steel is between X tons and Y tons, the weight and the coil separation number of each coil of band steel after pre-coiling are recorded; if the weight of each coil of sub-strip steel is not between X tons and Y tons, pre-coiling is carried out according to the maximum coil weight of Y tons, the sub-strip steel with the weight larger than X tons is defined as a qualified product, and the rest of the sub-strip steel in the pre-coiling is judged to be qualified and is discharged, wherein the qualified strip can be re-judged according to other packaging requirements.
In the implementation process, the strip quality determination unit 103 is specifically configured to: processing the data of the winding separation result based on a preset judgment condition to obtain a second judgment result of the N rolls of sub-strip steel, wherein if the first judgment result corresponding to the sub-strip steel is qualified, the second judgment result is qualified or qualified strip products are produced; otherwise, it is: secondary products, utilizable products, waste products and tail rolls.
Specifically, the preset determination conditions include: whether the actual size of each coil of strip steel is in a preset size grade or not; whether the defect of each coil of strip steel is in a preset severity; whether the actual weight of each coil of strip steel is in a preset weight range or not; whether the actual performance of each coil of strip steel is at a preset performance level.
