Description

The present invention relates to a process support device, a process support method and a program.

In the manufacturing industry such as the steel industry, it is common that standards are stipulated for set values and measured values in the process. Such standards are often provided to ensure quality and facilitate the process. For example, when hot-rolling a steel material such as a slab in a rolling mill in the steel industry, the steel material rolling order can be determined so that changes in attributes (width, thickness, hardness, etc.) of adjacent steel materials are small. Standards are stipulated for the amount of transfer such as coil width difference and coil thickness difference.

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the present specification and the drawings, components having substantially the same functional configuration are designated by the same reference numerals, so that duplicate description will be omitted.

Hereinafter, embodiments of a process support device, a process support method, and a program in a manufacturing process including a hot rolling process for manufacturing a coil from a slab will be described as an example, but the present invention is not limited to the process including the hot rolling process. , Applicable in various processes for which criteria are defined for those in which numerical values related to the process are segmented according to predetermined conditions.

FIG. 1 is a diagram conceptually showing a manufacturing schedule in a hot rolling process. FIG. 1 is a diagram in which coils (rectangles) are arranged in the order of scheduled rolling, and shows that the leftmost coil is rolled first and the rightmost coil is rolled last. Further, the long side of each rectangle is represented as the coil width. In the illustrated example, the schedule of the hot rolling process includes an initial pressure section and a normal section. The initial pressure section is a section for the purpose of running-in of the rolling roll, and in principle, the coils are arranged so that the coil width gradually increases (positive transition). However, even in the initial pressure section, an array of coils with an exceptionally narrow coil width may appear (reverse transition). On the other hand, the normal section is a section after the initial pressure section reaches the maximum coil width. In the normal section, the coils are arranged so that the coil width gradually narrows in principle in consideration of roll wear at the end in the width direction of the coil (positive transition). However, even in the normal section, an array of coils with an exceptionally wide coil width may appear (reverse transition). In each of the initial pressure section and the normal section, upper limit values are specified for the amount of change in the coil width and coil thickness in the case of forward transition and reverse transition. The upper limit is defined according to attributes such as coil material, coil width, and coil thickness.

FIG. 2 is a diagram showing a schematic configuration of a process support device according to an embodiment of the present invention. The process support device 100 shown in FIG. 2 is composed of a large computer such as a mainframe or an open system, or an information processing device such as a personal computer. The reference data 1 and the actual data 2 are stored in various memories such as ROM and RAM, a hard disk, or a recording medium such as a CD-ROM by an operation by an operator or an automatic import instruction that is periodically executed. The reference data input unit 110 inputs the reference data 1, and the reference data 1 is used for processing of the condition extraction unit 120. On the other hand, the actual data input unit 210 inputs the actual data 2, and the actual data 2 is used for the processing of the segmentation unit 220. The processing result of the condition extraction unit 120 is also used for the processing of the segmentation unit 220. The threshold value calculation unit 230 uses the processing result of the segmentation unit 220. The comparison unit 130 executes comparison based on the processing results of the threshold value calculation unit 230 and the condition extraction unit 120, and the comparison result is visualized by the visualization unit 140 and output to the display 4. The operation unit 150 receives an operation to be executed by the user on the operation device 5 based on the information output to the display 4, and the reference data update unit 160 updates the reference data 1. On the other hand, the threshold value calculated by the threshold value calculation unit 230 is stored as the threshold value data 3 by the threshold value storage unit 240.

The reference data 1, the actual data 2, and the threshold data 3 may be stored in another information processing device and transmitted to the process support device 100 by communication using a telecommunication line such as a LAN or the Internet. Further, each part of the process support device 100 does not have to be realized by a single information processing device, and may be realized by being distributed to a plurality of information processing devices. Specifically, for example, the reference data input unit 110, the condition extraction unit 120, the comparison unit 130, the visualization unit 140, the operation unit 150 and the reference data update unit 160, the actual data input unit 210, the segmentation unit 220, and the threshold value calculation. The unit 230 and the threshold value storage unit 240 may be realized by different information processing devices. One or more information processing devices (computers) are segmented into a reference data input unit 110, a condition extraction unit 120, a comparison unit 130, a visualization unit 140, an operation unit 150, a reference data update unit 160, and an actual data input unit 210. A program for operating the unit 220, the threshold value calculation unit 230, and the threshold value storage unit 240 may be provided.

FIG. 3 is a flowchart showing a schematic process of the process support method according to the embodiment of the present invention. The process shown in FIG. 3 is executed, for example, at the timing of updating the reference data of the hot rolling process. In the illustrated example, first, in the reference data input step S110, the reference data input unit 110 reads the reference data 1 from the recording medium and inputs it. Here, the reference data 1 is data including a reference defined for a numerical value related to a process segmented according to a predetermined condition. For example, when the process is a hot rolling process, the reference data 1 includes a reference regarding the attributes of the coils that are rolled continuously with each other in the schedule of the hot rolling process as shown in FIG. An example of segmentation will be described later.

FIG. 4 is a diagram showing an example of reference data in the example of FIG. In the illustrated example, the coil width of the first coil (front coil) in the manufacturing schedule of the hot rolling process and the coil width of the second coil (rear coil) to be rolled after the first coil. Tolerance in the production schedule is specified for each combination. In the example of FIG. 1, when the coil indicated by "i" is used as the front coil, the coil indicated by "j" is used as the rear coil. In the example shown in FIG. 4, the reference is a predetermined condition (for example, every 200 mm) with the first numerical value "coil width of the front coil" and the second numerical value "coil width of the rear coil". For each cell of the reference table composed of the first reference element (the partition to which the coil width of the front coil belongs) and the second reference element (the partition to which the coil width of the rear coil belongs) segmented according to (separation setting). Is regulated. In another example, the segmentation condition for the first numerical value (first condition) and the segmentation condition for the second numerical value (second condition) may be different. In this example, the criteria indicate the tolerance in the manufacturing schedule for each cell in the reference table.

When the reference table shown in FIG. 4 as described above is for the normal section in the manufacturing schedule of the hot rolling process shown in FIG. 1, the cell in the lower left half of the reference table shifts positively (the coil width of the front coil). On the other hand, the coil width of the rear coil is the same or smaller), and the cell in the upper right half shows the reverse shift (the coil width of the rear coil is larger than the coil width of the front coil). As a general tendency, combinations are allowed in cells that have a positive transition and a small coil width transition (○), and combinations are acceptable in cells that have a large coil width transition even in reverse transition and positive transition. Not allowed (x) or allowed but not recommended (△). Specifically, for example, when the coil width of the front coil is 1400 mm, the reverse transition in which a coil having a coil width of 800 mm is combined as the rear coil is not allowed (x), but the forward transition in which a coil having a coil width of 1200 mm or 1400 mm is combined is not allowed. Is acceptable (〇). Further, a forward transition having a large transfer amount when a coil having a coil width of 1000 mm is combined and a reverse transition having a small transfer amount when combining a coil having a coil width of 1600 mm are allowed but not recommended (Δ).

In addition, although FIG. 4 illustrates a simplified reference table of 7 elements × 7 elements = 49 cells, in reality, the coil width delimiter setting may be made finer or other conditions may be combined. In some cases, a reference table with thousands of cells is defined. Further, in the example of FIG. 4, the tolerance in the production schedule is defined by three classes of 〇, Δ, and ×, but the tolerance may be defined by more or less classes, or numerical values.

Further, in the above, the reference table shown in FIG. 4 is used for the normal section in the manufacturing schedule, but a reference table for the initial pressure section may be provided separately. As described above, the reference included in the reference data 1 may be defined for each of a plurality of categories in which the processes are classified according to a condition (third condition) different from the condition for segmenting the numerical value (coil width). ..

With reference to FIG. 3 again, next, in the condition extraction step S120, the condition extraction unit 120 extracts the condition for segmentation from the reference data 1 input in the step S110. In the reference table illustrated in FIG. 4 above, the first numerical value "coil width of the front coil" and the second numerical value "coil width of the rear coil" related to the process are predetermined conditions (separation setting every 200 mm). ) Is segmented. For example, the condition extraction unit 120 specifies the condition from the reference data such as the above reference table even when the condition itself for segmentation is not described in the reference data 1.

Next, in the actual data input step S130, the actual data input unit 210 reads the actual data 2 from the recording medium and inputs it. Here, the actual data 2 is data including the actual value of the numerical value for which the standard included in the reference data 1 is defined. For example, the actual data 2 includes a value indicating the attributes of the coils rolled continuously with each other as actual results in the schedule of the hot rolling process as shown in FIG. Here, as illustrated in FIG. 4, in the reference data 1, the reference is defined for the numerical value segmented according to the condition, whereas the actual value included in the actual data 2 is acquired in step S130. It is not segmented at the time it is done.

FIG. 5 is a diagram showing an example of actual data in the example of FIG. In the illustrated example, the actual data 2 includes coil ID (ID unique to each coil), coil width, coil thickness, carbon content (information indicating material or chemical composition), workability (easy-to-manufacture material, normal material, etc.). Difficult-to-manufacture material), rolling lot ID (which lot was rolled), rolling order (order in rolling lot), and part (starting pressure section (S) or normal section (N)) )including. Although the example of FIG. 5 is simplified, the actual data 2 may include more information. The actual data 2 includes the actual value of the coil width, but at this point, the coil width is not segmented (specifically, divided into units of 200 mm) as in the reference table shown in FIG.

With reference to FIG. 3 again, then, in the width segmentation step S140, the segmentation unit 220 includes the reference included in the actual data 2 input in the step S130 according to the conditions extracted by the condition extraction unit 120 in the step S120. Segment the actual value of the numerical value related to. In the example of the hot rolling process shown in FIG. 5, the first actual value “coil width of the front coil” and the second actual value “coil width of the rear coil” related to the process are set as predetermined conditions ( A performance table consisting of the first performance element (the division to which the coil width of the front coil belongs) and the second performance element (the division to which the coil width of the rear coil belongs) segmented according to the division setting every 200 mm is generated. To. In another example, the segmentation condition for the first actual value (first condition) and the segmentation condition for the second actual value (second condition) may be different. The actual table generated in step S140 is the same table as in FIG. 4, but there is no data in each cell at this stage.

As mentioned above, if the reference table is defined for each of a plurality of categories, segmentation is also performed for each category. That is, in the above example, the segmentation unit 220 segments the coil widths of the front coil and the rear coil for each category of the initial pressure section and the normal section, and generates a performance table for each category. The conditions for segmentation may differ from category to category.

Next, in the width threshold value calculation step S150, the threshold value calculation unit 230 calculates the threshold value from the frequency distribution for each segment with respect to the actual value segmented in the step S140. Specifically, for example, the threshold value calculation unit 230 calculates one or a plurality of threshold values according to the cumulative frequency in the frequency distribution of the transition amount of the coil width. The determination result based on these threshold values corresponds to, for example, the tolerance in the reference data 1. For example, when calculating a threshold from a cumulative frequency distribution for each segment, a threshold indicating the limit of the range normally performed (for example, cumulative frequency 95%) and a threshold indicating the limit of the range rarely performed (for example, cumulative). Frequency 99%) can be calculated.

FIG. 6 is a graph showing an example of the threshold value calculation method in the example of FIG. As shown in FIG. 6, in general, the transition amount of the coil width, that is, the difference between the coil widths of the front coil and the rear coil that are continuously rolled from each other, increases the frequency as it is smaller, and decreases as it increases. Shows the distribution of rolling shoulders. Here, as described above with reference to FIG. 1, there are an initial pressure section and a normal section in the manufacturing schedule of the hot rolling process, and there is a difference in the number of coils included between these sections. In addition, the direction (positive or negative) of the coil width shift amount is reversed. In addition, there are forward and reverse shifts in the coil width shift, and the frequency of forward shifts is higher than that of reverse shifts. In consideration of these points, it is preferable to calculate the threshold values of a total of four categories of forward transition and reverse transition for each of the initial pressure section and the normal section, as described below.

7A to 7D are graphs showing an example in which the threshold values of a total of four categories of forward transition and reverse transition are calculated for each of the initial pressure section and the normal section by the threshold calculation method shown in FIG. FIG. 7A illustrates the normal transition of the normal section, FIG. 7B illustrates the reverse transition of the normal section, FIG. 7C illustrates the forward transition of the initial pressure section, and FIG. 7D illustrates the reverse transition of the initial pressure section. There is.

FIG. 8 is a diagram showing an example of a determination result based on the threshold value of the actual value in the example of FIG. In the example shown in FIG. 8, the cumulative frequency of 95% or less is defined as the normal implementation range (〇), the region of more than 95% and 99% or less is rarely implemented (Δ), and the cumulative frequency is 99%. The determination result is determined as a range (x) in which the area exceeding the above is not implemented. The threshold value calculation unit 230 or the comparison unit 130, which will be described later, determines and stores the determination result as described above for each cell of the performance table generated in step S120.

With reference to FIG. 3 again, next, in the width threshold value saving step S160, the threshold value storage unit 240 stores the threshold value calculated in step S150 as the threshold value data 3. For example, the saved threshold value is used for determining the actual data input from the next time onward.

Next, in the width comparison step S170, the comparison unit 130 compares the actual value segmented in the step S140 with the reference defined in the reference data 1. More specifically, the comparison unit 130 determines the determination result based on the threshold value of each cell of the performance table illustrated in FIG. 8 by the standard (tolerance) defined for each cell of the reference table illustrated in FIG. ). In the subsequent visualization step S180, the visualization unit 140 visualizes the result of comparison by the comparison unit 130 and outputs it to the display 4.

FIG. 9 is a diagram showing an example of the comparison result visualized in the example of FIG. In the example shown in FIG. 9, the result of the comparison by the comparison unit 130 is visualized as a comparison result table having the same cell configuration as the reference table exemplified in FIG. 4 and the performance table exemplified in FIG. .. More specifically, in the comparison result table exemplified in FIG. 9, the first element is the coil width of the front coil divided by 200 mm, and the second element is the coil width of the rear coil also divided by 200 mm. The coil width of. In each cell of the comparison result table composed of these elements, the result of comparing the corresponding cells of the reference table and the actual table is displayed by an icon.

For example, in the comparison result table shown in FIG. 9, when the criteria and the judgment results in the corresponding cells of the reference table and the actual table match (all 〇, both ×, or both Δ), the icon Is not displayed. If the criteria and judgment results in the corresponding cells of the criteria table and the actual table do not match, an icon is displayed. For example, in a cell having a coil width of 1400 mm for the front coil and a coil width of 1000 mm for the rear coil, the reference specified in the reference table shown in FIG. 4 is Δ (unfavorable but acceptable), whereas FIG. Since the judgment result in the performance table shown in (1) is × (range not implemented), an icon (Δ / ×) is displayed. On the other hand, in the cell having a coil width of 1200 mm for the front coil and a coil width of 1400 mm for the rear coil, the reference specified in the reference table shown in FIG. 4 is × (not allowed), whereas the actual result shown in FIG. 8 is shown. Since the judgment result in the table is Δ (rarely implemented), the icon (× / Δ) is displayed.

Here, as described above, a reference table of several thousand cells may actually be defined, and in such a case, the actual table and the comparison result table also have thousands of cells. In such a case, the visualization unit 140 may visualize the comparison result and output it to the display 4 in such a manner that cells whose reference and determination results in the reference table and the actual result table do not match can be easily found. .. Specifically, for example, the visualization unit 140 may preferentially display on the display 4 a table having many difference detection points among the comparison result tables generated for each process category. Further, for example, the visualization unit 140 may list the number of cells in which the reference and the determination result do not match in each category before displaying the table of each category on the display 4. Alternatively, the visualization unit 140 may preferentially display on the display 4 cells having a large dissociation among the cells whose reference and the determination result do not match (in this case, the cell will be described with reference to FIG. 9 above. In this example, the ○ / × icon is displayed with priority over the △ / × icon).

As mentioned above, if the reference table and the performance table are specified for each of a plurality of categories, segmentation is also performed for each category. That is, in the above example, the comparison unit 130 compares the reference defined in each cell of the reference table with the determination result of each cell of the actual table for each category of the initial pressure section and the normal section.

FIG. 10 is a diagram showing an example of detailed information visualized in association with the comparison result exemplified in FIG. For the detailed information, for example, by selecting an icon (× / Δ, etc.) indicating that the reference and the determination result do not match in the comparison result table shown in FIG. 9, the detailed information as shown in FIG. 10 can be obtained. It is displayed on the display 4. In the illustrated example, the detailed information includes the coil IDs, coil widths, and coil thicknesses of the front and rear coils, the rolling order and location of the rear coils, and the rolling lot ID. The user who referred to the detailed information visualized in this way has what common the front and rear coils of the rolling results, which were marked as × (not allowed) in the standard but △ (rarely implemented range) in the actual results. It can be confirmed whether it has characteristics. For example, in FIG. 10, although the coil width is in the 1200 mm range to the 1400 mm range, which is not allowed by the standard, the set of the front coil and the rear coil that have been actually rolled has a feature that the coil thickness is thicker than 7 mm. Can be confirmed.

FIG. 11 is a diagram showing an example of information that is further developed and visualized from the detailed information illustrated in FIG. In the examples shown in FIGS. 11A and 11B, when the rolling lot ID displayed in the example of FIG. 10 is selected on the display 4, the target coil is located at which part of the rolling lot. It will be displayed as to what to do, and you can see how it was rolled in the lot. The user who refers to the information visualized in this way can confirm what kind of information the coil rolled before the target coil has. For example, before and after the coil in which the coil width is rolled by the reverse shift in FIG. 11 (A), as shown in FIG. 11 (B), there are many easily manufactured materials with little roll wear, so even if the reverse shift occurs. It can be inferred that there would have been no problem.

With reference to FIG. 3 again, next, in the reference data update step S190, the reference data update unit 160 updates the reference data 1. Specifically, the user who referred to the comparison result visualized in step S180 examines the update content of the reference, the operation unit 150 accepts the user's operation, and the reference data update unit 160 accepts the reference according to the received operation. Update data 1.

Alternatively, the reference data update unit 160 may update the reference data 1 based on the result of comparison by the comparison unit 130 without visualization depending on the update content, that is, skipping the above step S180. For example, when updating to a stricter standard (for example, the portion where the Δ / × icon is displayed in the example of FIG. 9), the table value may be automatically updated without visualization. In the case of an update that relaxes the standard (for example, the part where the × / △ icon is displayed in the example of FIG. 9), × (not allowed) to △ (not recommended) or △ (not recommended) to ○ If (allowable) is relaxed (however, it is limited to cells adjacent to the cell whose standard is ○), the table value may be automatically updated without visualization.

According to the configuration as described above, the condition extraction unit 120 extracts the condition for categorizing the numerical values in the reference, and the segmentation unit 220 segments the actual value according to this condition, so that the reference is based on the comparison unit 130. The comparison with the actual value becomes easy, and the comparison result visualized by the visualization unit 140 becomes easy to see. By facilitating the comparison between the standard and the actual value, deviation from the standard of the actual value can be found. In addition, if the standard can be changed, the standard can be updated by reflecting the actual value, and a standard incorporating past manufacturing order creation know-how can be created.

Further, when the threshold value calculation unit 230 calculates the threshold value from the frequency distribution for each segment, it is possible to obtain a determination result corresponding to the standard for the actual value, and the comparison result between the standard and the actual value by the comparison unit 130 is visualized. Part 140 can be visualized in an easy-to-understand form (in the above example, icons using 〇, Δ, and ×).

The steps S140 to S170 described above have been described as steps for segmenting the actual value of the coil width, calculating the threshold value, comparing with the reference, and the like, but as shown in FIG. 3, the coil thickness is similarly the same. Steps S240 to S270 for segmenting the actual value, calculating the threshold value, comparing with the reference, and the like are executed in parallel, and in step S180, the comparison result may be visualized for both the coil width and the coil thickness.

Although the preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, the present invention is not limited to such examples. It is clear that a person having ordinary knowledge in the field of technology to which the present invention belongs can come up with various modifications or modifications within the scope of the technical ideas described in the claims. , These are also naturally understood to belong to the technical scope of the present invention.
