Description

Technical Field

[0001] The invention relates to the field of steel manufacturing, and in particular to a packaging method for hot-rolled steel coils and related equipment. Background Art

[0002] The continuous casting billet is heated in the heating furnace and sent to the hot rolling unit by rollers for rolling. After rough rolling, finishing rolling, laminar cooling and other processes, the rolled steel strip is finally rolled into a formed steel coil by the coiler, and then the steel coil is unloaded by the coil unloading trolley. When the coil unloading trolley reaches the baling machine position, the trolley falls down, and the steel coil is placed on the baling machine. The baling machine starts baling. After baling one layer, the baling trolley moves forward to baling the next layer. The number of layers is set according to the steel type and the width of the steel coil. The steel coil baling machine is a relatively important link in the entire steel coil production line, which has a direct impact on the production rhythm and efficiency of the entire hot rolling production line.

[0003] At present, there are three main packaging methods for hot-rolled steel coils: single bundling, double bundling and fasteners. In production, it was found that some steel grades and some specifications were packaged with straps, and the straps often broke during the lifting process, resulting in loose coils. At the same time, it was found that some steel grades were almost all packaged with fasteners, which was costly. The choice of packaging method is simply distinguished based on the thickness and cold strength of the steel coils, resulting in problems such as broken straps and loose coils and high packaging costs. It is necessary to set the bundling method according to the product steel grade and width, or user needs, to avoid the loose coils caused by strap breakage during transportation, and to prevent unnecessary costs caused by excessive packaging and bundling.

[0062] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0063] In the following description, specific embodiments of the present invention will be described with reference to steps and symbols performed by one or more computers, unless otherwise stated. Therefore, these steps and operations will be mentioned several times as being performed by a computer, and computer execution referred to herein includes operations by a computer processing unit of electronic signals representing data in a structured form. This operation converts the data or maintains it at a location in the computer's memory system, which can be reconfigured or otherwise change the operation of the computer in a manner familiar to testers in the field. The data structure maintained by the data is a physical location in the memory, which has specific characteristics defined by the data format. However, the principles of the present invention are described in the above text, which does not represent a limitation, and testers in the field will understand that the various steps and operations described below can also be implemented in hardware.

[0064] The principles of the present invention operate with many other general or special purpose computing, communication environments or configurations. Examples of well-known computing systems, environments and configurations suitable for use with the present invention may include, but are not limited to, handheld phones, personal computers, servers, multiprocessor systems, microcomputer-based systems, mainframe computers, and distributed computing environments, including any of the above systems or devices.

[0065] The terms "first", "second", and "third" in the present invention are used to distinguish different objects rather than to describe a specific order. In addition, the terms "include", "have", and any variations thereof are intended to cover non-exclusive inclusions.

[0066] In view of the problems existing in the current packaging method of hot-rolled steel coils, it is necessary to formulate a scientific packaging plan to reduce the loss of yield caused by the loose coils of hot-rolled steel coils and the increase in costs caused by manual rework, while reducing the proportion of fasteners used in the current production of thick-gauge high-strength steel and reducing the cost of raw material packaging.

[0067] The hot rolling process personnel established a strapping force analysis model, fully considered the influence of various relevant factors, and developed a scientific classification and packaging plan. After multiple rounds of offline small batch and batch experiments, the results showed that the model is highly safe and the breakage rate of the strapping is significantly reduced. At the same time, the thick specifications of some steel products can be converted from fastener packaging to strapping packaging mode. The model is embedded in the manufacturing management system for development, and the packaging method is determined based on the thickness, width, temperature and other information of the rolled steel coils in real time. The packaging method is sent to the rolling line control system through the interface in real time to control the baler to perform baling and packaging operations.

[0068] See also Figure 1 , Figure 1 This is a diagram of the architecture of a hot-rolled steel coil packaging system provided in an embodiment of the present invention. The hot-rolled steel coil packaging system mainly includes three components:

[0069] Component 1 - Packaging optimization model rule static table module;

[0070] Component 2 - Packaging optimization model calculation module;

[0071] Component 3-packaging message sending module;

[0072] The functions of the three components are described below:

[0073] 1) The static table maintenance module of the rolling coil packaging optimization model rules requires input parameters to maintain the calculation model, which include the brand of the steel coil, the minimum thickness, the maximum thickness, the steel coil warehouse report, the sampling code, the yield strength, the coiling temperature, the KK critical width-thickness product G1 under the width coefficient of 1.4, and the KKKK critical width-thickness product G2 under the width coefficient of 1.4.

[0074] 2) Rolling coil packaging optimization model calculation module, selects the brand that originally needs to be packaged with fasteners according to the rolling plan. If there is a steel grade with the same brand in this static table in the rolling plan, the product of its thickness × thickness × width and the number calculated by the width-thickness product model in the static table are compared with G1 and G2. If the calculated number is smaller than G1, double bundling is used. If the calculated number is between G1 (including equal to G1) and G2, quadruple bundling is used. If it is greater than or equal to G2, it is reported to be packaged with fasteners.

[0075] 3) The module for sending the telegrams requesting bundling sends the calculated coil packaging method to the process control machine in the form of telegrams through the data receiving and responding module in the communication front-end machine to control the bundling machine to perform bundling operations.

[0076] By adopting the above technical solution, a reasonable packaging and bundling method can be calculated according to the steel type, specification, temperature and other information of the steel coils taken off the hot rolling production line, that is, the reliability of steel coil packaging is ensured, while unnecessary costs are not incurred due to excessive packaging.

[0077] The following is an explanation of the packaging method of hot-rolled steel coils from the perspective of the packaging device of hot-rolled steel coils. Figure 2 , Figure 2 A schematic flow chart of a method for packaging a hot-rolled steel coil provided in an embodiment of the present invention includes:

[0078] 201. Determine whether the target steel coil included in the target rolling plan is a special steel coil. If so, execute step 202.

[0079] In this embodiment, the packaging device of the hot-rolled steel coil can determine whether the target steel coil included in the target rolling plan is a special steel coil, which is a steel coil initially packaged with a standby fastener. Specifically, the packaging device of the hot-rolled steel coil can determine the brand of the target steel coil, that is, obtain the brand of the target steel coil from the target rolling plan, and determine whether there is a target steel grade matching the brand of the target steel coil in the pre-constructed model rule static table. If the target steel grade exists in the model rule static table, it is determined that the target steel coil is a special steel coil, and step 202 is executed. If the target steel grade does not exist in the model rule static table, it is determined that the target steel coil is not a special steel coil, and other operations are executed.

[0080] It should be noted that when the packaging device of the hot-rolled steel coil constructs the model rule static table, it can first determine the brand, material specification, strength, and temperature width and thickness product of all special steel coils; and determine the number of straps and bundling method for each special steel coil in all special steel coils according to the brand, material specification, strength, and temperature width and thickness product of all special steel coils; and then construct the model rule static table according to the number of straps and the bundling method.

[0081] 202. Determine packaging parameters of the target steel coil according to the attribute information of the target steel coil.

[0082] In this embodiment, after determining that the target steel coil is a special steel coil, the packaging device of the hot-rolled steel coil can determine the packaging parameters of the target steel coil according to the attribute information of the target steel coil. The attribute information includes but is not limited to information such as the steel type, specification and temperature of the steel coil. Specifically, the packaging device of the hot-rolled steel coil can first determine the target thickness and target width of the target steel coil from the specifications of the attribute information; then multiply the square of the target thickness by the target width to obtain the packaging parameters, that is, the packaging parameters = target thickness * target thickness * target width.

[0083] It should be noted that the target thickness and target width are determined from the specifications of the attribute information. Of course, they can also be determined by other means. For example, the packaging device of the hot-rolled steel coil provides an input window, and the target steel coil is manually measured and input. Of course, the target steel coil can also be photographed and then the photograph is identified to obtain the target thickness and target width. There is no specific limitation, as long as the target thickness and target width can be determined.

[0084] 203. Compare the packaging parameters with the preset packaging threshold value to obtain a comparison result.

[0085] In this embodiment, after determining the packaging parameters of the target steel coil, the packaging device of the hot-rolled steel coil can compare the packaging parameters of the target steel coil with the preset packaging threshold value to obtain a comparison result, wherein the preset packaging threshold value is the first packaging threshold value G1 and the second packaging threshold value G2 calculated by the width-thickness product model corresponding to the target steel coil in the model rule static table, wherein the first packaging threshold value G1 is less than the second packaging threshold value G2, and the packaging parameter G is compared with the first packaging threshold value G1 and the second packaging threshold value G2 respectively to obtain a comparison result, which includes that the packaging parameter G is less than the first packaging threshold value G1, the packaging parameter G is greater than or equal to the first packaging threshold value G1 and less than the second packaging threshold value G2, and the packaging parameter G is greater than or equal to the second packaging threshold value G2.

[0086] 204. Determine the packaging method of the target steel coil based on the comparison results.

[0087] In this embodiment, if the comparison result is that the packaging parameter is less than the second packaging threshold value, the packaging method of the target steel coil is determined to be strap packaging; wherein, the packaging parameter is less than the second packaging threshold value, including two cases, one case is that the packaging parameter is less than the first packaging threshold value, and the other case is that the packaging parameter is greater than or equal to the first packaging threshold value and less than the second packaging threshold value. At this time, the packaging method of the target steel coil can be determined as strap packaging. When the comparison result is that the packaging parameter is less than the second packaging threshold value, the packaging method of the target steel coil is determined to be double bundle packaging, that is, the target steel coil is packaged with straps, and the number of straps is two. When the comparison result is that the packaging parameter is greater than or equal to the first packaging threshold value and less than the second packaging threshold value, the packaging method of the target steel coil is determined to be four bundle packaging, that is, the target steel coil is packaged with straps, and the number of straps is four. It can be understood that the number of straps in the above double bundle packaging and four bundle packaging is only for example, and of course it can also be adjusted according to actual conditions, and is not specifically limited.

[0088] If the comparison result is that the packaging parameter is greater than the second packaging threshold value, the packaging method of the target steel coil is determined to be fastener packaging, that is, when the packaging parameter is greater than the second packaging threshold value, the target steel coil is packaged with a fastener.

[0089] 205. Send the packaging method of the target steel coil to the hot rolling line control system, so that the hot rolling line control system controls the baler to perform a baling operation on the target steel coil according to the packaging method.

[0090] In this embodiment, after determining the packaging method of the target steel coil, the packaging device of the hot-rolled steel coil can send the packaging method of the target steel coil to the hot rolling line control system via an electric message. After receiving the packaging method, the hot rolling line control system can control the baler to perform bundling operations on the target steel coil according to the packaging method.

[0091] In summary, it can be seen that in the embodiment provided by the present invention, the packaging device for hot-rolled steel coils can determine the packaging parameters of the target steel coil, compare the packaging parameters with the preset packaging threshold value, and determine the packaging method of the target steel coil according to the comparison result. Therefore, a reasonable packaging and bundling method can be calculated according to the steel type, specification, temperature and other information of the steel coils coiled off the hot rolling production line, that is, the reliability of steel coil packaging is guaranteed, and unnecessary costs are not caused by excessive packaging.
