Description

Technical Field

[0001] The present invention relates to the technical field of automated control of steel production, and in particular to a method, device and system for adjusting the sequence of slabs in a direct-charging production organization. Background Art

[0002] Direct Hot Charge Rolling (DHCR) is an integrated steelmaking-continuous casting-rolling production technology. Under this direct charging production organization model, the direct continuous casting slabs are cut and then sent directly to the hot rolling heating furnace for steel charging, which can minimize losses. The direct charging production organization model requires the coordination and guarantee of multiple factors: the simultaneous stability and smooth operation of the steelmaking and hot rolling production lines; a reasonable order structure and sufficient order turnover; the timing of steelmaking slab output matching the hot rolling progress, and the ability to quickly adjust in the event of production fluctuations; the ability to accurately issue and timely adjust the DHCR schedule and transmit information on steelmaking slab output. If the steelmaking and continuous casting time or production capacity cannot be matched, steel rolling will not proceed smoothly.

[0003] In the case of multiple casting machines, factors such as the casting speed of each casting machine, the smoothness of the spraying station staff in unloading and loading the slabs, the difference between the steelmaking plan and the actual output, and the steelmaking feeding sequence may cause the actual slab incoming sequence to be inconsistent with the pre-set steel loading requirements. Manual intervention is required to adjust the incoming sequence of the actual slabs, which has an adverse impact on the efficiency of the direct loading production mode. Figure 1 As shown in the example, slabs A / B / C have a rolling thickness of 3.0mm, while slabs D / E have a rolling thickness of 3.5mm. The DHCR scheduling requirement for loading slab C is that slab C enters the hot rolling furnace before slab D. However, in actual production, slab D is delivered before slab C. This means that the actual delivery order of the slabs is inconsistent with the pre-set loading requirements, resulting in a jump in rolling specifications. When this occurs, the crane is currently adjusted to lift slab D and allow slab C to pass through first. This practice impacts logistics operations and negatively impacts the efficiency of the direct loading production model. Summary of the Invention

[0004] The problem solved by the present invention is that when the actual incoming order of slabs in the direct charging production organization mode is inconsistent with the pre-set steel charging requirements, the incoming order of the physical slabs needs to be adjusted, which has an adverse effect on the efficiency of the direct charging production mode.

[0009] If the conditions are met, the incoming order of the difference slabs in the set incoming order of slabs is adjusted according to the actual incoming order of slabs.

[0010] Optionally, the actual slab incoming order includes currently actually incoming slabs, and the set slab incoming order includes currently planned incoming slabs; and determining whether the actual slab incoming order is consistent with the set slab incoming order includes:

[0011] Determining whether the currently actually received slab is consistent with the currently planned incoming slab;

[0012] If they are consistent, it is determined that the actual slab incoming order is consistent with the set slab incoming order;

[0013] If not, it is determined that the actual slab incoming sequence does not match the set slab incoming sequence, and the current actual incoming slab and the current planned incoming slab are the difference slabs.

[0014] Optionally, the determining whether the difference slab satisfies a preset replacement rule includes:

[0015] determining whether the different slabs have the same replaceable rolling code;

[0016] If so, it is determined that the difference slab meets the preset replacement rule;

[0017] If not, it is determined that the difference slab does not meet the preset replacement rule.

[0018] Optionally, the determining whether the difference slab satisfies a preset replacement rule includes:

[0019] Determining whether the slab attributes of the difference slabs correspond to the same, wherein the slab attributes include steel type, slab size, and the rolling plan unit to which it belongs;

[0020] If so, it is determined that the difference slab meets the preset replacement rule;

[0021] If not, it is determined that the difference slab does not meet the preset replacement rule.

[0022] Optionally, after determining whether the difference slab satisfies a preset replacement rule, the method further includes:

[0023] If the preset replacement rule is not satisfied, the actual slab incoming order is adjusted according to the set slab incoming order.

[0024] Optionally, the adjusting the incoming order of the difference slabs in the set incoming order of slabs according to the actual incoming order of slabs includes:

[0025] According to the actual slab incoming order, the incoming order of the difference slabs in the set slab incoming order in the corresponding system is adjusted, wherein the corresponding system includes one or more of the WH hot rolling management system, the IS inventory management system, the PO order management system and the WS steelmaking scheduling management system.

[0026] Optionally, the method for adjusting the slab sequence in the direct-loading production organization further includes:

[0027] Before the slabs are charged into the furnace, the steps of obtaining the actual slab incoming sequence and the set slab incoming sequence are performed.

[0031] The present invention also proposes a slab sequence adjustment system in a direct-charging production organization, comprising: a hot rolling process machine and an ERP system; the hot rolling process machine is used to obtain the actual slab incoming sequence and the set slab incoming sequence; determine whether the actual slab incoming sequence is consistent with the set slab incoming sequence; if not, determine the difference slab between the actual slab incoming sequence and the set slab incoming sequence, and determine whether the difference slab meets the preset replacement rule, wherein the difference slab is two or more slabs; if satisfied, report a slab sequence adjustment message to the ERP system; the ERP system is used to adjust the incoming sequence of the difference slabs in the set slab incoming sequence according to the actual slab incoming sequence after receiving the slab sequence adjustment message.

[0032] The present invention compares the actual slab incoming order with the set slab incoming order. When the two do not match, discrepancies are identified and replacement rules are pre-set. When discrepancies meet the replacement rules, the incoming order of the discrepancies in the set slab incoming order is adjusted according to the actual slab incoming order, so that the set slab incoming order matches the actual slab incoming order. This ensures smooth DHCR furnace loading, resolves the direct impact of inconsistent incoming materials that restrict direct loading, and significantly improves the direct heating charging rate. Furthermore, the replacement operation on the corresponding system is implemented for discrepancies that meet the replacement rules, reducing tedious operations such as skipping and rearrangement. Physical slabs do not need to be frequently taken offline and put back online, reducing the need for physical slabs to be transported back and forth, ensuring the fastest possible loading of slabs into the furnace, reducing online waiting and adjustment time for slabs, improving logistics efficiency, improving production efficiency, and reducing energy loss. Furthermore, physical slabs do not need to be frequently taken offline and put back online, reducing the impact of operations on equipment, thereby reducing safety hazards.

[0035] Figure 3 This is another flow chart of the method for adjusting the slab sequence in the direct loading production organization according to an embodiment of the present invention. DETAILED DESCRIPTION

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] In a production organization model driven by sales, the slab number serves as a key value when loading slabs into the furnace. This key value is associated with the order and production target control information. Therefore, the order in which the slabs arrive at the furnace must align with the planned loading sequence. However, in a multi-casting system, factors such as the casting speed of each caster and the smoothness of the marking stations in unloading and loading slabs can make it difficult to align the order and timing of slab arrival with the planned loading sequence and time.

[0038] In order to resolve the above contradiction, the present invention proposes a method for adjusting the sequence of slabs in direct loading production organization.

[0039] like Figure 2 In one embodiment of the present invention, the method for adjusting the slab sequence in the direct loading production organization includes:

[0040] Step S100, obtaining the actual slab incoming order and the set slab incoming order.

[0041] Before the slabs are loaded into the furnace, the step of obtaining the actual slab incoming order and the set slab incoming order is performed. The actual slab incoming order and the set slab incoming order obtained here refer to the order of the slabs that have not yet been loaded into the furnace.

[0042] An image acquisition device captures slab images and performs image recognition to identify the actual slab incoming order. The image acquisition device can be a camera. The actual slab incoming order can be uploaded in real time or at regular intervals. The set slab incoming order is pre-set and stored in a preset database. During step S100, it is directly retrieved from the preset database.

[0043] The actual slab incoming sequence and the set slab incoming sequence can both be expressed as slab number sequence data with a certain order. For example, if there are slab numbers A, B, C, D, and E, the slab incoming sequence can be expressed as {A->B->C->D->E}; it can also be expressed as each slab number being accompanied by a sequential number. For example, if there are slab numbers A, B, C, D, and E, the slab incoming sequence can be expressed as {A-1, B-2, C-3, D-4, E-5}, where 1, 2, 3, 4, and 5 refer to sequential numbers.

[0044] Optionally, after each acquisition of the actual slab incoming order, the corresponding set slab incoming order is queried based on the slab numbers included in the actual slab incoming order. For example, if the actual slab incoming order is {A->C->B}, the set incoming order corresponding to slabs A, B, and C is queried based on the slab numbers A, B, and C included therein. Optionally, the actual slab incoming order and the set slab incoming order can be acquired simultaneously. Optionally, the set slab incoming order can be acquired in advance, and then the actual slab incoming order can be acquired. Furthermore, the set of slab numbers contained in the actual slab incoming sequence is a subset of the set of slab numbers contained in the corresponding set slab incoming sequence. For example, if the actual slab incoming sequence is {A->C->B}, then the corresponding set slab incoming sequence may be {A->B->C}, or it may be {A->C->D->B}, {A->C->E->D->B}, {A->C->E->D->F->B}, etc.

[0045] Step S200, determining whether the actual slab incoming order is consistent with the set slab incoming order.

[0046] The number of slabs for which the sequence is judged here may be one or more.

[0047] In one embodiment, the number of slabs for which sequence consistency is determined is one. Specifically, the actual slab incoming sequence includes the currently actually incoming slabs, and the set slab incoming sequence includes the currently planned incoming slabs; step S200 includes: determining whether the currently actually incoming slabs are consistent with the currently planned incoming slabs; if they are consistent, determining that the actual slab incoming sequence is consistent with the set slab incoming sequence; if they are inconsistent, determining that the actual slab incoming sequence is inconsistent with the set slab incoming sequence, and the currently actually incoming slabs and the currently planned incoming slabs are the discrepancy slabs.

[0048] After determining that the actual slab incoming order is consistent with the set slab incoming order, the actual slab incoming order and the set slab incoming order can be retrieved again, and the steps after the acquisition order are executed.

[0049] For example, for slabs A, B, C, and D, if the current actual incoming slab is D and the current planned incoming slab is C, then when the current actual incoming slab and the current planned incoming slab are judged for consistency, it is determined that the two are inconsistent. At this time, the current actual incoming slab D and the current planned incoming slab C are difference slabs; if the current actual incoming slab is D and the current planned incoming slab is also D, then when the current actual incoming slab and the current planned incoming slab are judged for consistency, it is determined that the two are consistent, and the actual slab incoming order is consistent with the set slab incoming order.

[0050] In another embodiment, the number of slabs for which order matching is determined is multiple, i.e., two or more. Specifically, the actual order of incoming slabs includes the multiple slabs actually received, and the set order of incoming slabs includes the multiple slabs planned to be received, and the two are compared. For example, for slabs A, B, C, and D, if the multiple slabs actually received are A->C->B and the multiple slabs planned to be received are A->B->C, A->C->B is compared with A->B->C to determine whether the order matches. Slabs with inconsistent orders are considered discrepant slabs.

[0051] Step S300: If not, determine the difference between the actual slab incoming order and the set slab incoming order, and judge whether the difference meets the preset replacement rule, wherein the difference is two or more slabs.

[0052] If "No" is displayed here, it means that the actual incoming order of slabs does not match the set incoming order of slabs.

[0053] Discrepant slabs refer to slabs whose actual incoming order differs from the planned order. For example, the discrepancies between the order A->C->B and A->B->C are slabs B and C. For another example, if the actual incoming slab is D and the planned incoming slab is C, then the actual incoming slab D and the planned incoming slab C are discrepant slabs.

[0054] Due to differences in slab steel grade and width, thickness, width, and steel grade in production orders, as well as rolling process constraints, not all slabs can be adjusted in the set slab incoming order (hereinafter referred to as the "set order"). By pre-setting replacement rules, when different slabs meet the preset replacement rules, the order of the different slabs in the set slab incoming order can be adjusted. When the different slabs do not meet the preset replacement rules, the order of the different slabs in the set slab incoming order cannot be adjusted.

[0055] Optionally, the determination of whether the difference slab satisfies the preset replacement rules includes: determining whether the difference slab has the same replaceable rolling code; if so, determining that the difference slab satisfies the preset replacement rules; if not, determining that the difference slab does not satisfy the preset replacement rules.

[0056] Among them, replaceable rolling codes can be assigned in advance to slabs with the same slab properties. Slabs with the same replaceable rolling codes can be adjusted in sequence, that is, they meet the preset replacement rules. Otherwise, the preset replacement rules are not met.

[0057] By adopting the batching rule and introducing the replaceable rolling code of the slab, the judgement of whether the setting order of the different slabs can be adjusted is realized by comparing the replaceable rolling codes of the different slabs. The operation is simple and easy to implement.

[0058] Optionally, the determination of whether the differential slab satisfies a preset replacement rule includes: determining whether the slab attributes of the differential slab correspond to the same, wherein the slab attributes include steel type, slab size, and the rolling plan unit to which it belongs; if so, determining that the differential slab satisfies the preset replacement rule; if not, determining that the differential slab does not satisfy the preset replacement rule.

[0059] The slab size includes at least one of slab thickness, slab width and slab length.

[0060] After obtaining the difference slabs, the slab properties of the difference slabs are obtained to determine whether the steel types of the difference slabs are the same, whether the slab sizes are the same, and whether the difference slabs are in the same rolling plan unit.

[0061] By comparing the slab properties of the difference slabs, it is determined whether the two meet the preset replacement rules, and then whether the difference slabs can be adjusted in order. The slabs that can adjust the set order can be limited, and then the slabs that cannot adjust the order can be restricted, avoiding adverse consequences caused by the adjustment of the slab order. The slabs that can adjust the order can be easily identified, so that the set order and the actual order are kept consistent, ensuring the smooth progress of DHCR.

[0062] Step S400: If the conditions are met, the incoming order of the difference slabs in the set incoming order of slabs is adjusted according to the actual incoming order of slabs.

[0063] If the discrepant slabs satisfy a preset replacement rule, the order of the discrepant slabs in the set slab incoming order is adjusted according to the actual slab incoming order, i.e., the set slab incoming order in the corresponding system is adjusted. The corresponding system may include one or more of a WH hot rolling management system, an IS inventory management system, a PO order management system, and a WS steelmaking scheduling management system. Alternatively, if the preset replacement rule is not satisfied, the actual slab incoming order is adjusted according to the set slab incoming order.

[0064] By comparing the actual slab incoming order with the set slab incoming order, when the two do not match, the difference slabs are determined, and replacement rules are pre-set. When the difference slabs meet the replacement rules, the incoming order of the difference slabs in the set slab incoming order is adjusted according to the actual slab incoming order, so that the set slab incoming order matches the actual slab incoming order, thereby ensuring the smooth progress of DHCR furnace loading, solving the direct impact of inconsistent incoming materials that restrict direct loading, and significantly improving the direct heating loading rate. In addition, the replacement operation on the corresponding system is implemented for the difference slabs that meet the replacement rules, reducing tedious operations such as skipping and rearranging. The physical slabs do not need to be frequently taken offline and put online, reducing the re-transport of the physical slabs, ensuring the fastest possible entry of the slabs into the furnace, reducing the online waiting and adjustment time of the slabs, improving logistics efficiency, improving production efficiency, and reducing energy loss. In addition, the physical slabs do not need to be frequently taken offline and put online, reducing the impact of operations on the equipment, thereby reducing safety hazards.

[0065] Optionally, the adjusting the incoming order of the difference slabs in the set incoming order of slabs according to the actual incoming order of slabs includes:

[0066] According to the actual slab incoming order, the incoming order of the difference slabs in the set slab incoming order in the corresponding system is adjusted, wherein the corresponding system includes one or more of the WH hot rolling management system, the IS inventory management system, the PO order management system and the WS steelmaking scheduling management system.

[0067] Among them, the replaceable rolling code mentioned above can be generated during DHCR scheduling. The replaceable rolling code can be generated according to business rules when the WH system establishes the DHCR schedule, and issued as one of the contents of the PDI (Production Data Input) production instruction.

[0068] Among them, the PDI file of the WH hot rolling management system records the actual replacement of slabs.

[0069] IS inventory management system: records the schedule number, schedule order number, schedule coil number and corresponding order information corresponding to the slab.

[0070] WS steelmaking scheduling management system: records the scheduling number, scheduling order number, scheduling steel coil number and corresponding order information corresponding to the planned billet.

[0071] PO order management system: record tracking quantity and its adjustment.

[0072] The processing logic of the sequence adjustment process is:

[0073] The WH system of the ERP system (short for Enterprise Resource Planning) receives the slab sequence adjustment message thrown by the hot rolling process machine, parses the information of the replaced slab (mainly the scheduling information such as the steel coil number corresponding to the replaced slab number), and then combines the slab and its current scheduling information to query the relevant data information in each system in the ERP. Based on the received replacement result content, the WH hot rolling management system scheduling file is updated. At the same time, the IS system interface is called to complete the correction of the IS / WS file data, and the PO system interface is called to complete the update of the order tracking quantity, fully realizing the system support for the replacement of the slab entering the furnace and ensuring that the system data is consistent with the actual on-site objects.

[0074] Specifically, if Figure 3 According to the actual slab incoming order, adjusting the incoming order of the difference slabs in the set slab incoming order in the corresponding system includes the following operations:

[0075] Receive slab replacement message;

[0076] Determine whether the message length of the slab replacement message is correct;

[0077] If the message length is incorrect, the message will be considered as discarded and an abnormality will be prompted;

[0078] If the message length is correct, the message parsing is started to identify the data fields such as coil number 1, planned slab number 1, actual slab number 1, coil number 2, planned slab number 2, actual slab number 2, and replacement time;

[0079] Use coil numbers 1 / 2 to query the schedule file and determine whether coil numbers 1 / 2 exist. If so, update the slab number, furnace order number, and cutting sequence of the schedule file based on the coil number.

[0080] The IS system interface is called to perform the following operations for the two slabs corresponding to coil numbers 1 and 2: The slab's actual slab number is used to determine whether the slab exists in the actual output table of the IS inventory management system. If so, the slab has been produced and is an actual slab. The actual slab is processed to determine whether the replacement requires a change in the order item. If the slabs before and after the replacement belong to the same order, no further adjustments are required. If the slabs before and after the replacement do not belong to the same order and the order item needs to be changed, the following operations are performed in sequence: cancel the original schedule, cancel the schedule confirmation, cancel the pending order, re-pend the order, re-schedule, and call the PO system interface to adjust the PO plan tracking quantity. If the slab does not exist in the actual output table of the IS inventory management system, it means that the slab has not been produced yet. Then use the planned slab number of the slab to query the plan table to determine whether the order item needs to be changed after the replacement. If the order item does not need to be changed, there is no need to continue to adjust. If the order item needs to be changed, execute: cancel the original schedule of the planned slab, cancel the schedule confirmation of the planned slab, cancel the pending order of the planned slab, re-pend the order of the planned slab, re-schedule the planned slab, and call the PO system interface to adjust the PO plan tracking quantity.

[0081] Furthermore, after the slab consumption is completed, the slab consumed by the steel coil is the slab in the output message of the hot rolling process machine, that is, the slab used in the actual rolling.

[0082] Furthermore, when a manually input setting sequence adjustment instruction is received, the setting sequence of the corresponding slabs is adjusted according to the instruction.

[0083] In one embodiment of the present invention, a slab sequence adjustment device in a direct-loading production organization includes one or more processors and a computer-readable storage medium storing a computer program. The one or more processors are configured to implement the above-described method for adjusting the slab sequence in a direct-loading production organization by executing the computer-readable storage medium. The advantageous effects of the slab sequence adjustment device in a direct-loading production organization of the present invention compared to the prior art are consistent with those of the above-described method for adjusting the slab sequence in a direct-loading production organization and are not further described here.

[0086] The ERP system is used to adjust the incoming order of the difference slabs in the set slab incoming order according to the actual slab incoming order after receiving the slab order adjustment message.

[0087] Among them, on the one hand, the hot rolling process machine can determine whether the slab needs to be adjusted in the set sequence through replacement rules.
