Description

  The present invention relates to a steel output lot editing system, an editing method, and an editing program for performing lot editing when casting steel products in a casting facility.

In the steel industry, when manufacturing a wide variety of steel plates, slabs are formed by casting with a casting facility such as a continuous casting facility. The larger the structure, the less time is required for replacing and setting up the steel output equipment, and the manufacturing cost is not increased.
Therefore, in order to reduce the manufacturing cost, it is a challenge how to combine various order components into a single production lot and produce a large lot. The above issues occupy a greater weight as the process continues to progress.

Conventionally, as a means of automating material consolidation work to reduce the types of materials used in the manufacture of steel products, for example, the total order weight is calculated for each scheduled material that represents the tensile strength, and the total order weight is determined in advance. If the material is less than the reference value, the material is determined as an aggregation target, and if the material to be used for each order is the aggregation target, find the material that is not subject to aggregation from the pre-determined manufacturable materials. There has been proposed a production management method in the steel industry in which the material used is determined (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 5-12303 (first page, FIG. 3)

However, in the above-described conventional example, it is determined whether the material to be aggregated or not to be aggregated based on a material with many alternative materials such as tensile strength, and by reducing the material to be aggregated, the extra material is reduced. The production frequency is increased by reducing the frequency of material generation. Therefore, although Ru can consolidate if intended for that component of the order is equal, there is an unsolved problem that can not at all be intensification when component i.e. the order component of the order is different .

  If such order components are different, whether there is a partner that the person in charge of each product type in the department in charge of quality control can combine and produce steel while looking at each chemical component value for each component type It was determined whether or not, and a component combination table was created manually in advance. Therefore, it is necessary to determine the existence of a partner capable of combining components each time a new component type is produced, and to update the component combining table. Therefore, there is an unsolved problem that it takes a long time to search for a partner that can be combined.

  In addition, if the component combination table is not complete, aggregation into a production lot is not successful, resulting in a problem in production cost. In other words, in the case where a leak occurs in the creation of the component combination table, it is determined that, in actual work, it is not possible to combine orders that can be combined together and steel produced, and as a result, the manufacturing cost will be affected. There are challenges.

  In order to create this ingredient combination table without omission, in the actual situation, when it is discovered that it can be combined in the process of creating a steel production lot, ask the person in charge of the quality control department each time. To determine the possibility of merging, and when it is determined that merging is possible, an operation to update the merging table is also necessary, and it is still unsolved that the steeling lot knitting work cannot be performed smoothly and quickly There are also issues.

  Therefore, the present invention has been made by paying attention to the unsolved problems of the above-described conventional example, and can easily determine the presence of order components that can be combined based on the order components.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic configuration diagram showing an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a host computer 1 connected to a server 2 composed of, for example, an engineering workstation. An information processing terminal 3 composed of a large number of personal computers arranged for each process is connected via a local area network 4.

  The host computer 1 is provided with an order database DB by series as a steel output order registration means for managing order data by series, and a plate order for handling product orders received in this order database DB at a steelworks. Categorized by product type, such as hot rolling (hot rolling) order, cold rolling (cold rolling) order, electromagnetic steel order, large steel order, medium steel order, billet order, wire rod steel order, etc. Are stored in the order files F1 to F8, the current in-process orders and the orders to be newly produced are extracted from the orders for each series stored in the order files F1 to F8, and the extracted series The order data is transmitted to the server 2.

  Here, as shown in FIG. 2, the order database DB by series stores demand order data in which product names, dimensions, quantities, and customer names representing product types such as demand order names, delivery dates, and materials are registered. The demand order registration file 11, the production order association file 12 that stores the production order association data representing the association between the demand order name and the production order name, and the demand order registration file 11 are converted by the production order association data, and the in-process inventory A manufacturing order data registration file 13 for storing manufacturing order data in which manufacturing order names, process order names, product names, dimensions, and quantities are registered in units of information;

The server 2 is provided with an outgoing steel lot knitting system 2A that creates an outgoing steel lot knitting based on production order data input from the host computer 1.
Then, the data calculation processing unit 20a provided in the steel output lot knitting system 2A refers to the component combination file 20b and the component information file 20c, and executes a steel output lot knitting process according to the production order, thereby producing a steel output lot knitting. The information is stored in the lot organization file and the steel production lot organization information is displayed on the display 20f.

  Here, in the iron and steel industry, as shown in FIG. 3, first, in the blast furnace 25, iron ore is reduced with coke to produce pig iron having a substantially constant component, and this pig iron is transferred to the converter 26, The molten steel is produced by blowing oxygen into the hot metal so that the steel type has a chemical component corresponding to the production order, and the molten steel produced for each refining is put into a ladle. This refining every time is called charge, and the amount of molten steel per charge depends on the capacity of the converter 26. Then, the molten steel of the ladle is supplied to the tundish 28 of the continuous casting equipment 27, cast to form a slab, and this slab is sent to a thick plate process or a hot rolling process. The number of slabs produced from this one-charge molten steel is called one lot, and the knitting (type and casting order) of each slab within this one lot is called a steel-out lot lot knitting.

Then, at the time when the latest production order is registered every day, the data calculation processing unit 20a determines whether or not it is possible to combine all the manufacturing orders based on the chemical components, and creates a component combination table. The component combination table creation process to be performed is executed, and then the outgoing steel lot knitting process is performed in which the outgoing steel lot knitting is performed with reference to the generated component combination table.
As shown in FIG. 4, in the component combination table creation processing, first, in step S1, the latest production order information is read from the order database DB by series in the host computer 1, and then the process proceeds to step S2 to read the manufacturing. Unit numbers are issued collectively from the production information that overlaps the same component system from the order information, and the issued unit numbers are stored in the component information file 20c together with the component information, and are also added to the production order.

  Next, the process proceeds to step S3, and the unit that can be combined for all unit numbers is searched to create the component combination table shown in FIG. In creating the component combination table, the unit number and component information stored in the component information file 20c are sequentially read from the top, and other unit numbers having component information that matches or overlaps the read component information are searched. By doing. That is, for example, as shown in Table 1 below, if there are four unit numbers “A”, “B”, “C”, “D” to “G” having the same chemical components but different individual component amounts, each unit Numbered component (2), component (4), component (5), component (8), and component (9) match, but component (1), component (3), component (6), component (7) ) Has different component amounts.

  Therefore, when a unit number that can be combined is searched for the unit number “A”, the unit number “B” matches for components other than the component amount of the component (3), and “A” for the component (3). Is an upper limit value of 1.00 mass%, a lower limit value of 0.90 mass%, and a target value of 0.95 mass%, whereas “B” is an upper limit value of 1.00 mass%, a lower limit value of 0.80 mass%, and a target value of 0.90 mass. %, And overlapping in the range of 1.00 mass% to 0.90 mass%, it is determined that both unit numbers “A” and “B” can be combined. However, since unit number “C” does not overlap with component (7), it is determined that it cannot be combined, and similarly, “D” to “G” also do not overlap with component (3). , It is judged impossible to tie. In addition, since both the unit number “B” and the unit numbers “D” to “G” are overlapped with each other, the components (1) and (3) are determined to be able to be combined.

  The results of combining unit numbers “A” and “B” that are determined to be combined in this way are shown in the column of unit numbers “A” and “B” in Table 1 below as shown in the column (3). ) Are changed to an upper limit value of 1.00 mass%, a lower limit value of 0.90 mass%, and a target value of 0.95 mass%. “D” to “G” also represent the result of combining “D”, “E”, “F”, and “G” that can be combined in the same manner as described above.

Next, the process proceeds to step S4, the created component combination table is stored in the component combination file 20b, and the component combination table creation process is terminated.
The process of FIG. 4 corresponds to the component combination table creating unit, the process of step S2 corresponds to the component information storage unit, and the process of step S3 corresponds to the table forming unit.
As shown in FIG. 6, in the steel output lot knitting process, first, in step S11, the predicted verification cast knitting situation grasp list shown in FIG. 7 is displayed on the display 3b. This prediction verification cast knitting status list represents the steel production schedule from today to 20 days after each unit number, and a schedule in which the steel production planned quantity (t) of each date is displayed for each unit number. And a tundish information writing unit for determining a steel production lot for each unit number based on the scheduled steel production quantity of the schedule unit.

  Next, the process proceeds to step S12, where it is determined whether or not the tundish information has been written in the tundish information writing unit. It is determined whether or not the process is to be finished. When the outgoing steel lot knitting process is finished, the process is finished as it is, and when the outgoing steel lot knitting process is not finished, the process returns to step S12.

  If the determination result in step S12 is that in which the tundish information is written in the tundish information writing unit, the process proceeds to step S14, and the written tundish information specifies a plurality of unit numbers. If a single unit number is specified, the process proceeds to step S15, and the input charge (CH) number is set in the vicinity of the input scheduled steelmaking date. A production order having a built-in amount that falls within the corresponding possible molten steel amount range is extracted, and the tundish number display column 31, the charge number display column 32, the possible molten steel range display column 33, and the built-in amount display column 34 shown in FIG. , A knitting suitability message display field 35, a unit number display field 36, and a lot organization display field 37 for listing the extracted production orders in the order of the steel bill width. Back Tsu door organization list from the display on the display 3b to the step S12.

When the determination result in step S14 is the combination information in which the tundish information designates a plurality of unit numbers, the process proceeds to step S15, and the component combination table stored in the component combination file 20b is referred to. It is determined whether or not merging is possible. When merging is possible, the process proceeds to step S15 without creating a merging / non-meritability message. When merging is impossible, the process proceeds to step S17. After creating an error message such as no lap range, the process proceeds to step S15.
The process of FIG. 6 corresponds to the steel output lot knitting means, of which the process of step S16 corresponds to the merging determination means, and the processes of steps S17 and S15 correspond to the determination result output means.

Next, the operation of the above embodiment will be described.
Now, it is assumed that today is June 10, and the component combination table creation process shown in FIG. 4 is automatically started by the knitting lot management system 2A of the server 2 at a preset time in the early morning of today.
In this component combination table creation process, the latest production order information registered in the order database DB by series of the host computer 1 is read (step S1), and the same component system is duplicated based on the chemical component information of each production order information. Unit numbers are issued together with manufacturing orders to be processed, and unit numbers and chemical components corresponding to the unit numbers are tabulated and stored in the component information file 20c (step S2).

  Then, the unit numbers stored in the component information storage file 20c are read in order from the top, and the remaining unit numbers are searched based on the chemical components of the read unit numbers, and can be combined having chemical components that overlap with themselves. 5 is extracted, and a component combination table in which the group number, the number of combined units, and the unit numbers that can be combined shown in FIG. 5 are listed is created (step S13), and the generated component combined table is stored in the component combined file 20b. This completes the component combination table creation process.

As shown in Table 1, the component combination table extracts unit numbers having the same chemical components, and has chemical components that overlap with all of the chemical components of the extracted unit numbers. It is determined that the unit number can be combined.
Therefore, in Table 1 described above, the unit numbers “A” and “B” differ only in the content of the component (3), and the upper limit value and the lower limit value of both are over in the range of 1.00 to 0.90 mass%. Since they wrap, both are determined as units that can be combined, and unit numbers “A” and “B” are displayed in group number “33” in FIG. 5. Similarly, unit numbers “B” and unit numbers “D” ˜ Only “G” is different only in the content of component (3), and both upper and lower limits overlap in the range of 0.90 to 0.80 mass%. , Unit numbers “D”, “E”, “B”, “F” and “G” are displayed in the group number “41” of FIG.

In this way, unit numbers are issued for each component system for all the latest production orders, and it is automatically determined whether or not it is a unit that can be steeled by combining the issued unit numbers. Thus, an ingredient combination table is automatically created.
Thereafter, the operator starts up the information processing terminal 3 and accesses the outgoing steel lot knitting system 2A in the server 2 via the LAN 4 to execute the outgoing steel lot knitting process.
In this steelmaking lot knitting process, first, on the display 3b, for each unit number described above, for example, the date of delivery described in the daily production order from today (June 10) to June 29, 20 days later, is traced back. A predicted verification cast knitting status grasp list shown in FIG. 7 is displayed, which shows the expected steel production amount and the cumulative steel production amount from today to the day of the production limit date determined in this manner.

  From this predicted verification cast composition status grasp list, the outgoing steel lot organization is created. At this time, for example, if the unit number described in the left outgoing steel group column is left-clicked with the mouse 3d, for example, the selected unit number is displayed. The unit combination table stored in the component combination file 20b is searched for a unit that can be combined. For example, when the unit number of number 178 selects “A”, “B” is displayed as the unit number that can be combined. When “D” to “G” of the number 176 are selected, “B” is displayed as the unit number that can be combined, and conversely, when the unit number “B” of the number 177 is selected, “A” as the unit number that can be combined. Alternatively, “D” to “G” are displayed.

  Therefore, for example, when considering the steelmaking lot organization on June 23, when the steelmaking lot organization of the unit number “B” of the number 177 whose molten steel amount is less than the possible amount of molten steel for one charge in the converter is performed. When the unit number “B” alone secures one charge, the amount of molten steel per charge is 280 to 338 t, and the amount of molten steel of the unit number “B” is 89 t in total, so the minimum possible amount of molten steel is 191 t. The remaining material will be generated.

For this reason, since it is difficult to form a lot with the unit number “B” alone, merging is considered. As described above, by left-clicking the unit number “B” with the mouse, “A” or “D” to “G” are displayed.
Therefore, when the unit numbers “ D ” to “G” are verified, the accumulated molten steel amount until June 23 is 2066 t. When the accumulated molten steel amount 89 t of the unit number “B” is added to this, the total accumulated molten steel of both units is “20”. The amount is 2155t, and the possible amount of molten steel per charge is 280 to 338t, which means that it is possible to produce steel without excess or deficiency with 7 charges.

Similarly, when the verification about the unit number "A", the cumulative amount of molten steel to June 23 is 867T, the which is added the accumulated amount of molten steel 89t of unit number "B" total cumulative amount of molten steel in both 956t Thus, it can be seen that the amount of steel that can be melted in one charge is 280 to 338 t, and that it is possible to produce steel without excess or deficiency in three charges.
Therefore, in actuality, the unit number “A”, “B”, and “D” to “G ” are knitted independently with the unit number “ For B, the unit number “A”, the unit numbers “D” to “G”, and the unit numbers “A” and “D” to “G” can be combined. Validate.

  First, the number 178 for selecting the unit number “A” with the tundish number H264 is set at the position of the number 178 corresponding to the unit number “A” in the tundish information writing unit of the prediction verification cast organization status grasp list. At the same time, when the allocation amount and the scheduled date of steel production (June 11) are set and verification is performed, a verification result screen shown in FIG. 8 is displayed on the display 3b. In the verification result screen of FIG. 8, the tundish number “H264” is displayed in the tundish number display field 31, the charge number, for example, “1” is displayed in the charge number display field 32, and 1 is displayed in the possible molten steel display field 33. The possible molten steel amount per charge “280-338” is displayed, the embedded amount display column 34 displays the embedded amount “298”, and the component unit number display column 36 displays the specified unit number “A”. The Here, since the verification is the unit number “A” alone and not a tie, a message indicating whether or not the tie is possible is not created, and no message is displayed in the message display field 35. Further, the unit number “A” corresponding to one charge is extracted from the production order of unfinished steel in the unit number “A” in the vicinity of the scheduled steel production date in the lot organization display column 37, and the extracted unit number “A” is displayed in the order of billet width. At this time, each unit number “A” includes steel slab length, hot rolled thickness, hot rolled width, slab unit weight, surplus amount in slab, presence / absence of express export, date of outgoing steel limit, requested outgoing steel The date and order delivery date are displayed, and necessary messages are displayed.

  In addition, a number 177 for selecting the unit number “B” with the tundish number H265 is set at the position of the number 177 corresponding to the unit number “B” in the tundish information writing unit of the prediction verification cast organization status grasping list, When verification is performed by setting the allocation amount and the scheduled date of steel production (June 11), a verification result screen shown in FIG. 9 is displayed on the display 3b. 9, the tundish number “H265” is displayed in the tundish number display field 31, the charge number, for example, “1” is displayed in the charge number display field 32, and 1 is displayed in the possible molten steel display field 33. The possible molten steel amount per charge “280 to 338” is displayed, the incorporated amount “303” is displayed in the incorporated amount display column 34, and the specified unit number “B” is displayed in the component unit number display column 36. The Again, since the verification is the unit number “B” alone and not a tie, a message indicating whether or not the tie is possible is not created, and no message is displayed in the message display field 35. Furthermore, the unit number “B” corresponding to one charge is extracted from the production order of unfinished steel in the unit number “B” in the vicinity of the scheduled date of steel production in the lot organization display field 37, and the extracted unit number “B” is displayed in the order of billet width. At this time, each unit number “B” includes steel slab length, hot rolled thickness, hot rolled width, slab unit weight, surplus amount in slab, presence / absence of express export, date of outgoing steel limit, requested outgoing steel The date and order delivery date are displayed, and necessary messages are displayed. Here, it appears in the vicinity of the scheduled steel output date of June 11 that can be understood from the estimated steel output amount of the unit number “B” displayed in the schedule section of the prediction verification cast organization status grasp list shown in FIG. Since there is no steel plan, the unit number “B” for steeling after June 21st is displayed.

  Similarly, when verifying the unit numbers “D” to “G” previously conjugated, there is no unit number to be newly conjugated as shown in FIG. Is not displayed, and the lot organization display column 37 shows from the production orders of unfinished steel in the unit numbers “D”, “E”, “F” and “G” in the vicinity of the scheduled steel production date. Unit numbers “D” to “G” corresponding to one charge are extracted, and the extracted unit numbers “D” to “G” are displayed in the order of billet width.

  On the other hand, when the unit numbers “A” and “B” are combined, the numbers 177 and 178 corresponding to the unit numbers “B” and “A” in the tundish information writing unit of the prediction verification cast organization state grasp list. In the position, the numbers 177 and 178 for selecting the unit numbers “B” and “A” with the tundish number H267 are set, and the allocation amount and the scheduled date of steel production (June 11) are set and verified. The verification result screen shown in FIG. 11 is displayed on the display 3b. In the verification result screen of FIG. 11, the tundish number “H267” is displayed in the tundish number display column 31, the charge number, for example, “1” is displayed in the charge number display column 32, and 1 is displayed in the possible molten steel display column 33. The possible molten steel amount per charge “280-338” is displayed, the incorporated amount display column 34 displays the incorporated amount “324”, and the component unit number display column 36 designates the specified unit numbers “A” and “B”. Is displayed. Here, since the verification is the combination of the unit numbers “A” and “B”, it is possible to combine “A” and “B” with reference to the component combination table stored in the component combination file 20b. Since it is possible to determine whether or not both are possible, no message is displayed in the message display field 35. Furthermore, in the lot organization display column 37, unit numbers “A” and “B” corresponding to one charge from the production order of unfinished steel in the unit numbers “A” and “B” in the vicinity of the scheduled steel production date are displayed. The extracted unit numbers “A” and “B” are displayed in the order of billet width.

  Similarly, when unit numbers “D” to “G” and “B” are conjugated, unit numbers “D” to “G” and “ Numbers 176 and 177 for selecting unit numbers “D” to “G” and “B” with tundish number H268 are set at positions 176 and 177 corresponding to “B”, and the number of charges, the assigned amount, and the steel output When verification is performed by setting a scheduled date (June 11), a verification result screen shown in FIG. 12 is displayed on the display 3b. Also in this case, since both can be combined, no message is displayed in the message display field 35, and the unit numbers “D” to “G” in the vicinity of the scheduled date of steel production are displayed in the lot organization display field 37. Unit numbers “D” to “G” and “B” corresponding to one charge are extracted from the production order of unfinished steel in “B”, and the extracted unit numbers “D” to “G” and “B” are extracted. Are displayed in the order of billet width.

  Furthermore, when unit numbers “D” to “G” and “A” are combined, unit numbers “D” to “G” and “A” in the tundish information writing unit of the predicted verification cast organization status grasping list are used. Are set at numbers 176 and 178 corresponding to the numbers 176 and 178 for selecting the unit numbers “D” to “G” and “A” with the tundish number H269, and the allocation amount and the date of steel production ( June 11) is set and verification is performed, a verification result screen shown in FIG. 13 is displayed on the display 3b. At this time, unit numbers “D” to “G” and “A” are combined, and when referring to the component combination table stored in the component combination file 20b, unit numbers “D” to “G” Since the combination with “A” is not possible, a non-combination message of “no component wrapping range, out of steelmaking ability range” is created, and this non-combination message is displayed in the message display field 35. By displaying the message indicating that the combination cannot be performed, the operator can immediately determine that the unit numbers “D” to “G” and “A” cannot be combined, and the lot organization is actually performed. Therefore, it is possible to reliably prevent the occurrence of defective component slabs. Even in this incompatibility state, the lot organization display column 37 displays the lot organization by the unit numbers “D” to “G” and “A”.

  When the operator wants to make a more detailed determination in this incompatibility state, the chemical components of the unit numbers “D” to “G” and “A” stored in the component information file 20c are read, and both are moved up and down. By displaying the portion where the components do not overlap, that is, the component range of the component (3) in Table 1 described above in red or the like, the operator can surely see why the two cannot be combined. be able to.

In this way, when a plurality of verifications desired by the operator are performed and the optimum steelmaking lot organization by component combination is determined, it is stored in the determined lot organization file 20d and work for the operator of the converter and continuous casting equipment. An instruction document is created and output as a form or as electronic data, which is instructed to the operator of the converter and continuous casting equipment.
Therefore, according to the above embodiment, the component combination table is always updated based on the latest production order, and it is determined whether or not the unit number, that is, the production order can be combined with reference to this component combination table, Since the outgoing steel lot knitting is performed based on the judgment result, even if it is a new variety at the time of outgoing steel lot knitting, if there is a component mate partner from the beginning, tying is possible, so it is possible to consolidate outgoing steel lots. Progress can be made to reduce manufacturing costs and inventory.

In addition, since it is possible to automatically determine whether or not tying can be performed at the time of knitting a steel-out lot, the waiting time until a determination result is obtained can be greatly shortened, and the manufacturing lead time can be shortened.
In addition, in the said embodiment, although the case where a component combination table preparation process and a steel extraction lot organization process were performed in the steel extraction lot organization system 2A of the server 2 was demonstrated, it is not limited to this, Information processing terminal You may make it perform all the processes by 3 side.

  Further, in the above embodiment, a case has been described in which a steeling lot knitting is automatically performed by instructing a unit number. However, the present invention is not limited to this. Judgment is made whether or not it is possible, and when it is judged that merging is possible, a list of unfinished steel production orders corresponding to the unit number is displayed on the display 3b, and a desired production order is extracted from the displayed production order However, it is also possible to organize the outgoing steel lot.
