[0021] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0022] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0023] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0024] See also Figure 1 , Figure 1 A schematic diagram of a process flow of a scrap steel tail coil processing method provided in one embodiment of the present invention, with reference to Figure 1 The scrap steel tail coil processing method comprises the following steps:

[0025] Step S101: Acquire the attribute information of the scrap steel tail coil to be processed.

[0026] Among them, the attribute information includes the initial length and the target processing length. The initial length can be understood as the distance between the two end faces of the scrap steel tail roll. The target processing length is the length set by technicians in this field, and can be set according to the maximum scrap steel length specified by the steelmaking furnace. The target processing length is less than the maximum scrap steel length. Different target processing lengths can also be set for scrap steel tail rolls of different materials. The target processing length can also be a value determined based on a preset processing length interval and an initial length. For example, the initial length is 2 meters, and the preset processing length is not more than 0.5m, so that the scrap steel tail roll to be processed can be cut into 4 parts. For another example, the initial length is 2.2 meters, and the preset processing length interval is not more than 0.5m, then the target processing length can be determined to be 0.44 meters, so that the scrap steel tail roll to be processed can be cut into 5 parts.

[0027] In one embodiment, the attribute information may also include data such as the weight and material of the scrap steel tail coil for subsequent processing. For example, based on the material, its melting point can be known, which facilitates the determination of the preset target temperature for subsequent heating during flame cutting. Knowing its weight can estimate the amount of scrap steel tail coil that can be added to the steelmaking furnace later, which facilitates production planning. The weight can be obtained by transferring the scrap steel tail coil to be processed to the load-bearing device through the transfer device in advance and weighing it.

[0028] As an example, the attribute information can be determined by the production line from which the tail coil of scrap steel to be processed comes, or by other methods known to those skilled in the art, which are not limited here.

[0029] Step S102: determining the required number of strapping tapes and the strapping position of each strapping tape according to the target processing length and the initial length.

[0030] Since the scrap steel tail roll will be scattered after cutting, it needs to be re-bundled before cutting to ensure that the scrap steel small roll will not be scattered after cutting. Therefore, it is necessary to determine the required number of strapping tapes and the strapping position of the strapping tape in advance, and bundle it in advance before cutting to ensure that the steel roll will not be scattered after cutting.

[0031] In one embodiment, the required number of strapping tapes is determined based on the target processing length and the initial length, including: if the initial length is an integer multiple of the target processing length, the required number of strapping tapes is determined based on the quotient of the initial length and the target processing length (the quotient minus 1); if the initial length is not an integer multiple of the target processing length, the integer value of the quotient of the initial length and the target processing length is determined, and the integer value is determined as the required number of strapping tapes. For example, if the initial length is 2 meters and the target processing length is not more than 0.5 meters, then the required number of strapping tapes is 3; for another example, if the initial length is 2.2 meters and the target processing length is not more than 0.5 meters, then the required number of strapping tapes is 4, and the actual processing length at this time is 0.44 meters. The actual processing length is used to replace the previous target processing length to determine the bundling position and the cutting position.

[0032] In one embodiment, the method further includes: if the initial length is not an integer multiple of the target processing length, the actual processing length is recalculated based on the initial length and the required number of strapping tapes, and the target processing length is replaced by the actual processing length. It can be understood that the target processing length is a maximum value of the processing length. Then, after the required number of strapping tapes is determined, in order to make the length of the cut small rolls uniform, a new actual processing length can be determined based on the required number of strapping tapes and the initial length, replacing the current target processing length. The actual processing length is equal to the quotient of the initial length and the required number of strapping tapes, that is:

[0033] Lactual = Linitial / (N+1);

[0034] Among them, L is the actual processing length, L is the initial length, and N is the currently determined required number of strapping tapes.

[0035] As an example, the method also includes: if the initial length is not an integer multiple of the target processing length, the number of integer values ​​can be understood. If the initial length of the scrap steel tail roll to be processed is just an integer multiple of the target processing length, then the scrap steel tail roll to be processed can be evenly divided, and it can be cut in a normal cutting manner. However, the initial length of the scrap steel tail roll to be processed is often not an integer multiple of the target processing length. At this time, there will be a small scrap steel roll with a weight and length that is significantly smaller than other small scrap steel rolls, which is not conducive to subsequent reuse. It may cause a feeding ratio problem when the subsequent feeding is not paid attention to the differences between the small scrap steel rolls. To address this problem, the two situations can be distinguished during the planning of the strapping tape. Then, for the small scrap steel rolls whose length is less than the target processing length, another type of strapping tape is used for bundling in order to distinguish them.

[0036] In one embodiment, the bundling position of each strapping tape is determined according to the target processing length and the initial length, including: if the initial length is an integer multiple of the target processing length, the position separated by the target processing length from the starting strapping position is determined as the bundling position of a strapping tape, and the starting strapping position is used as the bundling position of a strapping tape, and the starting strapping position is half the position of the target processing length from one end of the scrap steel tail roll to be processed. This position determination method can further ensure that the bundling strap is in the middle of the scrap steel roll after subsequent cutting; if the initial length is not an integer multiple of the target processing length, the position separated by the actual processing length from the starting strapping position is determined as the bundling position of a strapping tape, and the starting strapping position is used as the bundling position of a strapping tape, and the starting strapping position is half the position of the actual processing length from one end of the scrap steel tail roll to be processed.

[0037] In accordance with the above embodiment, the method further includes: if there is at least one strapping position that is the same as the original position of the original strapping position of the scrap steel tail roll to be processed, or the position error between the original position of the original strapping position of the scrap steel tail roll to be processed and the strapping position of any strapping position is less than a preset error threshold (such as less than 1 cm, etc.), the original strapping position is removed as the available strapping position, and the strapping is no longer repeated, and the original strapping can be directly used. In addition, the required number of strapping tapes can also be reduced accordingly according to the number of available original strapping tapes.

[0038] Step S103: bundling the tail coils of scrap steel to be processed by using the required number of bundling straps based on the bundling positions of all the bundling straps.

[0039] The specific strapping method is not limited here and can be implemented in a manner known to those skilled in the art. When there are strapping tapes of different types, they can be arranged according to the position arrangement rules of different types of strapping tapes provided in the aforementioned embodiments. When the original strapping tape can be reused, the strapping operation at the location of the original strapping tape can be omitted. As an example, when reusing the original strapping tape, the integrity of the original strapping tape can be verified by machine vision (for example, taking an image of the original strapping tape that needs to be reused for one week, and performing image feature extraction to obtain the original image feature, and comparing the original image feature with the pre-extracted damaged image feature of the strapping tape. If the comparison fails, it means that the original strapping tape is intact, otherwise it is considered that the original strapping tape is damaged). If the original strapping tape is intact and there is no damage, the original strapping tape can be reused. If there is damage, the new strapping tape is still strapped at the corresponding strapping position.

[0040] Step S104: Compress the interlayer strip steel of the bundled scrap steel tail coil to be processed until the gap between each layer of strip steel is smaller than a preset gap threshold, and tighten each packing belt on the compressed scrap steel tail coil to be processed.

[0041] The preset gap threshold may be set to 1 / 10 of the thickness of the steel strip, or other values ​​set by those skilled in the art.

[0042] Since the interlayer steel strips are compressed, the previously tied straps may become loose, so the strapping can be tightened to ensure that the strapping is firmly tied.

[0043] During the cutting process, at least the cutting position of the scrap steel tail roll to be processed is kept in a clamped state by the clamping device to ensure smooth cutting.

[0044] Step S105: cutting the compacted scrap steel tail roll to be processed based on the position of the strapping tape on the compacted scrap steel tail roll to be processed to obtain a plurality of scrap steel small rolls for processing the scrap steel tail roll to be processed.

[0045] In one embodiment, the compacted tail roll of scrap steel to be processed is cut based on the position of the strapping tape on the compacted tail roll of scrap steel to be processed, including: determining the middle point between two adjacent strapping tapes on the tail roll of scrap steel to be processed by machine vision recognition, and determining the middle point as the position to be cut; heating the position to be cut by a flame cutting torch; when the heated temperature of the position to be cut reaches a preset target temperature, flame cutting is performed at the position to be cut by the flame cutting torch; during the flame cutting process, the tail roll of scrap steel to be processed is rotated to make relative movement between the tail roll of scrap steel to be processed and the flame cutting torch until the flame cut slit is connected to form a circle on the tail roll of scrap steel to be processed.

[0046] When the flame cutting slit is connected in a circle on the tail roll of scrap steel to be processed, it means that the cutting is completed at this position.

[0047] As an example, the preset target temperature can be determined by the material of the scrap steel tail coil to be processed. Different materials have different melting points. Then, the preset additional temperature (such as 100° C.) is increased on the basis of the melting point to obtain the preset target temperature.

[0048] Step S106: flatten each scrap steel coil.

[0049] In one embodiment, a small scrap steel roll is flattened, including: after supporting the small scrap steel roll from the bottom, squeezing the small scrap steel roll from the top so that the small scrap steel roll is in a concave state; squeezing the small scrap steel roll from both ends and the top until the small scrap steel roll is in an M shape, thereby completing the flattening process of the small scrap steel roll to obtain a finished scrap steel product.

[0050] Since there are still certain safety hazards in the form of steel coils during transportation, they can be squeezed by hydraulic tools and other tools to obtain finished scrap steel products to avoid the danger caused by the steel coils spreading out. The degree of flattening can be set by technicians in this field as needed, and can be determined according to the weight, material, length, etc. of the scrap steel coils. Since the scrap steel tail coils may be elastic, there may be a risk of rebound if a simple flattening method is used, so the above method can be used to flatten them to avoid the risk caused by rebound. Among them, a specific implementation method of flattening is to first support the scrap steel coils from two points at the bottom of the scrap steel coils, and apply sufficient force from directly above to deform the scrap steel coils until they are concave; then apply sufficient force in the middle and both ends of the upper part of the flattened scrap steel to make the scrap steel M-shaped. The above M-shape is only an example of a shape, and does not limit the shape to a standard symmetrical shape. The specific flattening force can be set by technicians in this field as needed.

[0051] Following the above embodiment, after obtaining the scrap steel products, the method further includes: transferring the scrap steel products to a corresponding target storage warehouse according to the type of the strapping tape on the scrap steel products.

[0052] As an example, for the convenience of management, a corresponding identification label can be attached to each scrap steel product. The identification label can be made of a material that does not affect the secondary utilization of the scrap steel, and represents the material, weight, length and other information of the scrap steel product.

[0053] If the strapping tapes on the scrap steel products are of the same strapping tape type, then this batch of scrap steel products will be transported to the same target storage warehouse. However, as mentioned in the example provided in the above embodiment, there may be scrap steel products with at least two types of strapping tapes. In this case, the target storage warehouses corresponding to the different strapping tape types can be pre-set, and then the corresponding storage can be done. Multiple target storage warehouses can be physically separated or different storage areas in the same storage space. In this way, the appropriate scrap steel products can be selected for use as needed.

[0054] The following is an exemplary description of the scrap steel tail coil processing method provided above with a specific embodiment. The processing process can be achieved through intelligent flame cutting. Specifically, the weight, width, material, length of the scrap steel after processing and other attribute data of the scrap steel tail coil (attribute information of the scrap steel tail coil to be processed) are input into the HMI (Human Machine Interface) of the flame cutting and processing intelligent production line of the scrap steel tail coil; the scrap steel tail coil to be processed is moved to the steel coil seat of the packaging station of the scrap steel coil processing line; the scrap steel tail coil is tied with multiple strapping tapes by a robot, and the number of strapping tapes (the required number of strapping tapes) is the same as the number of small coil segments required after cutting. Taking the initial length as an integer multiple of the target processing length as an example, the distance between the first strapping tape and the last strapping tape and the edge of the scrap steel tail roll is half of the required length of the small roll after cutting (i.e. the length of the scrap steel after processing, the target processing length), and the distance between the two strapping tapes is the length of the small roll after cutting (the target processing length); the scrap steel tail roll to be processed is moved to the steel roll seat of the scrap steel roll processing line cutting station; a robot is used to move multiple flame cutting torches to the upper surface of the scrap steel tail roll, and align them with the middle point of every two strapping tapes; the flame cutting torch is turned on to heat the oxygen and fuel gas, ignited, and the middle point of the two strapping tapes is heated; an optical high The thermometer detects the temperature of the heating point. When the temperature is higher than the melting point by about 100°C (that is, the preset target temperature is reached), the slag blowing oxygen of the flame cutting torch is turned on for flame cutting, and the scrap steel tail coil is rotated to achieve relative movement with the flame cutting torch to achieve the purpose of cutting, until the cut seam is connected on the scrap steel tail coil to form a circle, and the scrap steel tail coil is cut into more than two small scrap steel coils; the scrap steel tail coil is moved to the steel coil seat of the flattening station of the scrap steel coil processing line, and the upper and lower hydraulic heads are used to flatten the small scrap steel coils to form scrap steel products; the scrap steel products are moved out from the steel coil seat of the flattening station of the scrap steel coil processing line and enter the storage warehouse (target storage warehouse).

[0055] The scrap steel tail roll processing method provided in the above embodiment obtains the initial length and the target processing length of the scrap steel tail roll to be processed, determines the required number of strapping tapes and the strapping position of each strapping tape according to the target processing length and the initial length, bundles the scrap steel tail roll to be processed with the strapping tapes of the required number of strapping tapes based on the strapping positions of all strapping tapes, cuts the bundled scrap steel tail roll to be processed based on the strapping tape positions on the bundled scrap steel tail roll to be processed, and obtains a plurality of scrap steel small rolls, so as to process the scrap steel tail roll to be processed, thereby providing a safe and reliable scrap steel tail roll cutting and processing method, which can safely cut overly long scrap steel tail rolls into suitable lengths and avoid the occurrence of safety accidents.
