Description

Technical Field

[0001] This specification relates to the field of steel rolling technology, and more specifically, this application relates to an automatic coil slitting control method and related equipment. Background Technology

[0002] The cold-rolled tin-plating unit is a continuous production line. Incoming coils are welded to the tail of the previous coil at the inlet before entering the line, and are slit at the outlet using a flying shear to produce finished coils. In related technologies, the secondary automation of the tin-plating unit's outlet slitting process uses master data from the steel coil (PES) to perform pre-calculation of the slitting. However, in the coordinated automatic slitting calculation between the primary and secondary systems, the lack of a precise material tracking calculation method prevents the secondary automation from optimizing the slitting strategy based on real-time and accurate strip remaining quantity. Tin-plating operators can only roughly calculate the slitting length based on existing material tracking data and order requirements, and then manually enter the slitting length into the HMI (Human-Machine Interface) to execute the slitting. However, manual slitting operations negatively impact the production line's automation level, resulting in low efficiency, susceptibility to human error, and the inability to optimize the slitting strategy in real-time, leading to increased scrap, lower yield, and higher production costs.

[0039] The automatic coil slitting control method proposed in this application creates a real-time and accurate strip tracking calculation method through an automated control system. It fully considers the plate length and welding position information in the tin-plating unit production line that affect the calculation of slitting length and gives the optimal shearing strategy to achieve precise automatic slitting control at the tin-plating exit.

[0040] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus. The technical solutions of the embodiments of this application will now be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them.

[0041] The automatic control system of the 1420 tin-plating unit was developed and designed by Pratt. The automatic coil slitting function is completed by the coordinated operation of process automation (secondary automation) and PLC automation (primary automation). First, the secondary automation performs pre-calculation of coil slitting according to the slitting strategy based on the master data of the coil issued by PES and the order requirements. However, in actual application, operations such as defect scrapping and sampling inspection are determined by the actual operation of the strip steel on site. Ignoring the sampling, scrapping length, and unloading tail coil length can lead to the slitting of sub-coils being too small. Inaccurate calculation of the strip length in the looper and uncertainty of the tail coil length on the uncoiler can also cause inaccurate calculation of the secondary automatic coil slitting, which cannot achieve the optimal slitting of the coil. It may even cause the automatic optimization slitting strategy to become confused and the automatic coil slitting to fail.

[0042] Currently, the secondary automation of the tin plating unit's outlet coiling process pre-calculates the coiling based on the master data sent by the PES. However, in the coordinated automatic coiling calculation between the primary and secondary systems, the lack of precise material tracking calculation methods (especially for calculating, sampling, and cutting the remaining strip amount at the uncoiler tail and the amount of strip within the looper) prevents the secondary automation from optimizing the cutting strategy based on real-time and accurate remaining strip amount. Tin plating operators can only roughly calculate the coiling length according to the order requirements based on existing material tracking data, and then manually enter the coiling length into the HMI interface to execute the coiling. However, manual coiling operations negatively impact the production line's automation level, resulting in low efficiency, human error, and an inability to optimize the coiling strategy in real-time, leading to increased scrap, lower yield, and higher production costs.

[0043] Please see Figure 1 This is a schematic flowchart of an automatic roll-to-roll control method for a type of rolled material provided in an embodiment of this application, which may specifically include:

[0044] S110. Obtain the remaining length information of the master coil and the weld position information, wherein the remaining length information of the master coil includes the remaining length information on the uncoiler mandrel, the distance information between the uncoiler and the cross-cutting shear, the distance information between the cross-cutting shear and the welding machine, and the strip length information between the welding machine and the flying shear.

[0045] For example, such as Figure 2 The diagram shows a schematic of a tin-plating production line layout, including an uncoiler, an inlet cross-cutting shear, a welder, a looper, an outlet flying shear, and a coiler. The remaining length information of the master coil includes the remaining length on the uncoiler mandrel, the distance between the uncoiler and the cross-cutting shear, the distance between the cross-cutting shear and the welder, and the strip length from the welder to the flying shear. When multiple steel strips are linked for transmission, welding is required to ensure continuous transmission. However, the weld seam needs to be removed before entering the coiler to prevent weld seams from appearing in the middle of the finished coil.

[0046] The actual physical location of the flying shear on the production line was determined by comparing the drawings with actual measurements. The remaining total length L of the mother roll. remain It is the sum of the remaining strip length L0 on the uncoiler mandrel, the fixed distance L1 from the uncoiler to the cross-cutting shear, the fixed distance L2 from the cross-cutting shear to the welding machine, and the strip length L3 from the welding machine to the flying shear.

[0047] L remain =L0+L1+L2+L3

[0048] S120. Determine the coiling plan information based on the remaining length information of the master coil, the coiling target, and the coiling strategy. For example, obtain the steel coil master data from the production management system, perform coiling pre-calculation based on the coiling target and the coiling strategy, and determine the coiling plan information, i.e., how much material is needed for each coil.

[0049] S130. Based on the above weld location information and the above roll-out plan information, control the exit flying shear to perform the cutting operation.

[0050] For example, the cutting operation is controlled by adjusting the coil length and welding position information based on the coiling plan and whether there is a weld seam at the exit. Automatic coiling control is achieved by precisely calculating the length of the sheet metal and the welding position information in the tin plating unit production line.

[0051] In summary, the automatic coil slitting control method proposed in this application creates a real-time and accurate strip tracking calculation method through an automated control system. It fully considers the plate length and welding position information in the tin plating unit production line that affect the calculation of slitting length and gives the optimal shearing strategy, thereby achieving precise automatic coil slitting control at the tin plating exit.

[0052] In some embodiments, the above method further includes:

[0053] Obtain export cutting length information and unloading coil length information, wherein the export cutting length includes export scrap length and sampled strip length;

[0054] Based on the above-mentioned remaining length information of the master roll, the above-mentioned export cutting length information, and the above-mentioned unloading tail roll length information, the remaining length correction information of the master roll is determined;

[0055] Based on the above-mentioned remaining length correction information of the master volume, the above-mentioned volume division objectives, and the above-mentioned volume division strategies, the volume division plan information is determined.

[0056] For example, the remaining length of the master coil also needs to be adjusted based on the export scrap length, the sampling strip length, and the unloading length, and pre-calculated for slitting according to the coil target and slitting strategy. The two slitting targets for the finished coil are: ① slitting the finished coil according to the maximum weight; ② slitting the finished coil according to the average weight. Unloading the coil refers to the operation of unwinding the coil from the drum during the production process. Unloading is usually carried out at the end of the coiling machine or coil production line. This process requires gradually unwinding the coil, laying it flat on a workbench or conveyor belt for subsequent processing or use. The sampling strip is the material to be cut for relevant physical and chemical tests.

[0057] In some embodiments, the above method further includes:

[0058] The remaining length information of the master coil is determined based on the sum of the remaining length information on the uncoiler mandrel, the distance information between the uncoiler and the cross-cutting shear, the distance information between the cross-cutting shear and the welding machine, and the strip length information between the welding machine and the flying shear.

[0059] For example, the remaining total length L of the volume remain The sum of the remaining strip length L0 on the uncoiler mandrel, the fixed distance L1 from the uncoiler to the cross-cutting shear, the fixed distance L2 from the cross-cutting shear to the welding machine, and the strip length L3 from the welding machine to the flying shear:

[0060] L remain =L0+L1+L2+L3

[0061] In some embodiments, the above method further includes:

[0062] The remaining length information on the uncoiler mandrel is determined based on the inner diameter, outer diameter, and thickness information of the steel coil on the uncoiler.

[0063] For example, the remaining length of the steel coil on the inlet uncoiler is calculated from the inner diameter information, outer diameter information, and thickness information of the steel coil.

[0064] Specifically, it can be calculated using the following formula:

[0065]

[0066] Among them, D in For information on the inner diameter of the steel coil, D out Th represents the outer diameter of the steel coil, and Th represents the thickness of the steel coil.

[0067] In some embodiments, the above method further includes:

[0068] The above-mentioned steel coil thickness information is determined based on the actual thickness information of the steel coil and the upper and lower limits of the steel coil thickness.

[0069] For example, the remaining length of the steel coil on the uncoiler is calculated using the mother coil thickness Th issued by the secondary level. However, in actual production, this value deviates significantly from the raw material thickness measured by the primary level. To prevent inaccurate calculation of the slitting weight due to a large deviation in the mother coil thickness value issued by the secondary level, the primary level defines upper and lower limits (0.12-0.55mm) for the mother coil thickness value when calculating the remaining strip length on the uncoiler. When the issued mother coil thickness is within the upper or lower limit range, the primary level uses the mother coil thickness issued by the secondary level in the calculation; when the mother coil thickness exceeds the upper limit range, the primary level selects to use either the upper or lower limit boundary value in the calculation.

[0070] In some embodiments, the above method further includes:

[0071] Obtain information on the looper pass number, top roll diameter, bottom roll diameter, top roll distance, and looper trolley running height;

[0072] Based on the above information on the looper pass number, the above information on the top roller diameter, the above information on the bottom roller diameter, the above information on the top roller distance, and the information on the looper trolley running height, the strip length information from the welding machine to the flying shear is determined.

[0073] For example, the strip length from the welding machine to the flying shear is the physical distance between the welding machine and the flying shear plus the amount of strip sleeved within the looper. The amount of strip sleeved varies, and because the bottom roll and top roll are not perpendicularly distributed, the strip distribution has an angle in the vertical direction, such as... Figure 3 As shown, the strip length from the welding machine to the flying shear can be calculated using the following formula:

[0074]

[0075] In the formula, N represents the number of loop passes ( Figure 3 As shown, N=6), d is the diameter information of the top roller and bottom roller, x is the distance information between the two top rollers (center distance), and h is the running height information of the looper trolley. The running height information of the looper trolley can be obtained by counting by the looper trolley encoder.

[0076] In some embodiments, the above method further includes:

[0077] Determine the elongation correction factor based on the elongation rate of the target material;

[0078] The remaining length information of the master volume is extended and corrected based on the aforementioned extension correction coefficient.

[0079] For example, the strip length will be affected after the material undergoes tension straightening. Considering the strip elongation, the remaining strip length is corrected as follows: (1+0.02)×L act The remaining weight of the steel coil is calculated, and a new coiling plan is formulated according to the coiling strategy.

[0080] In some implementations, automatic splitting control can be coordinated by a primary or secondary automation system, such as... Figure 4 The diagram shown is a schematic representation of another automatic roll-to-roll control method proposed in this application, specifically including steps S210 to S230:

[0081] S210, Level 2 Pre-segmentation

[0082] The secondary automation system obtains the steel coil master data from the PES production management system and performs pre-calculation of coiling based on the coiling objectives and strategies. The two coiling objectives for finished coils are: ① to cut finished coils according to the upper weight limit; ② to cut finished coils according to the average weight.

[0083] S220. When there are no welds on the production line, the first and second levels work together to calculate the remaining length of the master roll from the uncoiler to the flying shear. The second level then re-executes the rewinding calculation and issues a rewinding command.

[0084] S2201. Calculation of the remaining length of the master roll from the uncoiler to the flying shear.

[0085] By comparing the drawings with actual measurements, the actual physical position of the flying shear on the production line is determined, and this physical position is used as a reference point in the secondary stage. The remaining total length L of the mother roll. rema in is the sum of the remaining strip length L0 on the uncoiler mandrel, the fixed distance L1 from the uncoiler to the cross-cutting shear, the fixed distance L2 from the cross-cutting shear to the welding machine, and the strip length L3 from the welding machine to the flying shear.

[0086] L remain =L0+L1+L2+L3 (1)

[0087] S2202, Calculation of remaining strip length on the uncoiler, Level 1 automation defines upper and lower limits for the thickness of the incoming master coil.

[0088] The remaining length of the steel coil on the inlet uncoiler is calculated from the inner diameter, outer diameter, and thickness of the steel coil. Where D in D out These are the inner and outer diameters of the steel coil, respectively.

[0089] When calculating the remaining length of the steel coil on the uncoiler, the thickness Th of the master coil issued by the secondary stage is used. However, in actual production, this value deviates significantly from the raw material thickness measured by the primary stage. To prevent inaccurate calculation of the slitting weight due to a large deviation in the master coil thickness value issued by the secondary stage, the primary stage defines upper and lower limits (0.12-0.55mm) for the master coil thickness value when calculating the remaining strip length on the uncoiler. When the issued master coil thickness is within the upper or lower limit range, the primary stage uses the master coil thickness issued by the secondary stage in the calculation; when the master coil thickness exceeds the upper limit range, the primary stage selects to use either the upper or lower limit boundary value in the calculation.

[0090] S2203. The strip length from the welding machine to the flying shear is the physical distance between the welding machine and the flying shear plus the amount of strip sleeved within the looper. The amount of strip sleeved varies, and because the bottom roll and top roll are not perpendicularly distributed, the strip distribution has an angle in the vertical direction, as shown in the figure below.

[0091]

[0092] N is the number of looper passes, N=6, d is the diameter of the top and bottom rollers, x is the center distance between the two top rollers, and h is the actual running height of the looper trolley, which can be obtained by counting using the looper trolley encoder.

[0093] S2204. The flying shear sampling and waste sheet cutting are all set using the first level. The first level calculates the length of the unloading roll at the inlet and the waste / material cutting at the outlet and transmits it to the MTR. Then, the calculated remaining length is subtracted from the length of the unloading roll or waste material and sent to the second level.

[0094] L act =L remain -L ex-cut -L tail (3)

[0095] L remain Total remaining length of the master roll, L act L is the calculated value of the actual remaining strip length after deducting scrap and tail material from the mother coil. ex-cut For export scrap cutting and sampling strip length, L tail This refers to the length of the unloaded roll.

[0096] S2205. The strip length will be affected after the material undergoes tension straightening. The secondary calculation takes into account the strip elongation and corrects the remaining strip length value as follows: (1+0.02)×L act The remaining weight of the steel coil is calculated at the second level, and a new coiling plan is formulated according to the coiling strategy.

[0097] S230. When there is a weld seam on the production line, the first level tracks the weld seam by counting with the encoder and the weld seam synchronization position, and the second level sends the weld seam cutting code to the first level according to the weld seam.

[0098] In summary, the secondary automation system obtains the master data of the steel coils from the PES production management system and performs pre-calculation of coiling based on the coiling target and strategy. Simultaneously, a real-time, accurate strip tracking calculation method is created within the automation control system, fully considering factors affecting the coiling length calculation, such as elongation, strip thickness, sampling and scrap amount, and unloading coil length. The primary automation system feeds back the accurate remaining length of the master coil to the secondary system in real time, allowing the secondary system to recalculate the coiling and provide the optimal shearing strategy, achieving precise automatic coiling control at the tin-plating exit.
