It should be understood that the specific implementation methods described herein are only used to explain the present invention and do not limit the protection scope of the present invention.

[0038] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0040] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0041] The present invention provides an aluminum rod heating furnace, comprising a feeding conveying mechanism, a preheating section and a heating section; Figure 2 As shown, the aluminum rod heating furnace also includes a type sorting acquisition module, a first temperature acquisition module, a second temperature acquisition module, a sorting generation module, a calculation module and a controller.

[0042] The type sorting acquisition module is used to acquire the aluminum bar types and initial sorting of the aluminum bars to be heated on the feeding conveying mechanism. Specifically, the aluminum bar heating furnace also includes an image acquisition module, which is used to acquire images of the aluminum bars to be heated on the feeding conveying mechanism, acquire the aluminum bar types and initial sorting of the aluminum bars to be heated according to the images of the aluminum bars to be heated, and feed back to the type sorting acquisition module.

[0043] The image acquisition module obtains the image of the aluminum bar to be heated, obtains the image contour of the aluminum bar to be heated, compares the similarity between the image contour of the aluminum bar to be heated and the pre-stored standard contour of different types of aluminum bar images, and determines the type of aluminum bar to be heated on the feeding conveying mechanism and the corresponding initial sorting. Of course, based on the comparison of the similarity between the image contour of the aluminum bar to be heated and the pre-stored standard contour of different types of aluminum bar images, the type of aluminum bar to be heated on the feeding conveying mechanism can be further determined by comparing the pixel grayscale value of the image of the aluminum bar to be heated with the pre-stored standard pixel grayscale value of different types of aluminum bar images, and then the initial sorting is determined. The different types of aluminum bars to be heated are first identified, that is, each type of aluminum bar to be heated corresponds to an identification symbol such as an identification number, and then the aluminum bars to be heated on the feeding conveying mechanism are sorted from close to the preheating section to away from the preheating section, to obtain the initial sorting.

[0044] The first temperature acquisition module is used to acquire the preheating temperature data of the preheating section; the second temperature acquisition module is used to acquire the heating temperature data of the heating section. Both the first temperature acquisition module and the second temperature acquisition module can be temperature sensors to respectively acquire the air temperature of the preheating section and the flame temperature in the heating section and feed them back to the controller.

[0045] The sorting generation module is used to obtain multiple different new sortings according to preset rules and initial sorting. Here, the preset rules include but are not limited to random sorting and sorting by aluminum bar mass, by aluminum bar required preheating temperature, by aluminum bar required heating temperature, and by aluminum bar diameter.

[0046] The calculation module stores a preheating benefit function and a heating benefit function, which is used to obtain the preheating time, preheating waiting time, heating time and heating energy consumption of each aluminum bar to be heated in each sort according to the aluminum bar type, initial sort and new sort, calculate the preheating benefit value according to the preheating time, preheating waiting time and the preheating benefit function, calculate the heating benefit value according to the heating time, heating energy consumption and the heating benefit function, calculate the total benefit value of each sort according to the preheating benefit value and the heating benefit value, calculate the total time of each sort according to the preheating time, preheating waiting time and heating time, and calculate the total energy consumption of each sort according to the heating energy consumption.

[0047] Preferably, the calculation module includes a time-energy consumption calculation unit and a benefit calculation unit.

[0048] The time and energy consumption calculation unit is used to calculate the preheating time according to the type, mass, initial temperature and preheating temperature of the aluminum rod to be heated and the air temperature of the preheating section, calculate the heating time and heating energy consumption according to the type, mass and preheating temperature of the aluminum rod to be heated and the flame temperature of the heating section, and calculate the preheating waiting time according to the heating time.

[0049] For different types of aluminum bars to be heated, the required preheating temperature and required heating temperature are different. For example, the required preheating temperature of aluminum bars is usually around 200℃. The purpose is to remove impurities such as moisture and oxides in the aluminum bars, and at the same time improve the plasticity and ductility of the aluminum bars for extrusion molding. The required heating temperature of aluminum bars is usually required to be between 400℃ and 550℃. This range is based on the melting point of aluminum of about 660℃, and considering the need to avoid overheating during the heat treatment process to cause the material performance to deteriorate. It can not only ensure the plastic deformation ability of aluminum materials, but also avoid performance degradation caused by overheating. The specific required preheating temperature and heating temperature should be adjusted according to the alloy composition, size and required performance of the aluminum bars, which will not be repeated here.

[0050] According to the type and quality of the aluminum rod to be heated, the temperature rise characteristics of the aluminum rod to be heated in the preheating section are obtained. The temperature rise characteristics determine the time required for the aluminum rod to be heated from the initial temperature to the preheating temperature (i.e., the preheating time) when the air temperature in the preheating section is greater than or equal to the required preheating temperature of the aluminum rod to be heated. In order to facilitate the calculation of the preheating time, the inner cavity of the preheating section is connected to the inner cavity of the heating section through a pipeline. The preheating section preheats the aluminum rod to be heated through the waste heat of the heating section, and a solenoid valve and a blower controlled by a controller are installed in the pipeline. The controller controls the action of the blower and the solenoid valve according to the air temperature of the preheating section, controls the flow rate of the waste heat of the waste heat flowing into the preheating section, adjusts the air temperature of the preheating section, and makes the air temperature of the preheating section within a preset preheating temperature range. The preset preheating temperature range can be . is the preheating temperature, Greater than 0 indicates a preset preheating temperature range adjustment coefficient, which can be 0.1, 0.2, 0.3, 0.5, etc., preferably 0.1 or 0.2.

[0051] As a preferred technical solution, the preheating time is based on the formula .in, represents the initial temperature, Indicates the air temperature in the preheating section, which can be the median value of the preset preheating temperature range. Indicates the mass of the aluminum bar to be heated, represents the specific heat capacity of the aluminum rod to be heated, Indicates the warm-up time. represents the attenuation constant, Indicates the preheating correction value corresponding to the aluminum bar to be heated.

[0052] The benefit calculation unit is used to calculate the preheating benefit value according to the preheating time, the preheating waiting time and the preheating benefit function, and to calculate the heating benefit value according to the heating time, the heating energy consumption and the heating benefit function, and to calculate the total benefit value according to the preheating benefit value and the heating benefit value.

[0053] Preferably, the preheating benefit function is , the heating benefit function ;

[0054] in, represents the preheating benefit value, represents the heating benefit value, represents the warm-up time benefit factor, represents the heating time benefit factor, represents the heating energy efficiency factor, represents a natural constant, Indicates the warm-up time. Indicates the warm-up waiting time. represents the first preheating benefit adjustment coefficient and the second preheating benefit adjustment coefficient respectively, Indicates the heating time. Indicates heating energy consumption, They respectively represent the first heating benefit adjustment coefficient and the second heating benefit adjustment coefficient.

[0055] Preferably, the total benefit value ;in, Indicates the total number of aluminum bars to be heated on the feed conveyor mechanism. Indicates The preheating benefit value of the aluminum bar to be heated, Indicates The heating efficiency value of the aluminum rod to be heated.

[0056] The controller is used to select the preferred sorting from the initial sorting and the new sorting according to the total benefit value, total time and total energy consumption of each sorting and the heating priority strategy selected by the user, adjust the sorting of the aluminum bars to be heated on the feed conveying mechanism according to the preferred sorting and control the action of the feed conveying mechanism to convey the aluminum bars to be heated to the preheating section.

[0057] The heating priority strategy includes three types: total benefit value priority, total time priority and total energy consumption priority. The user can select the heating priority strategy from the three types: total benefit value priority, total time priority and total energy consumption priority.

[0058] If the selected heating priority strategy is total benefit value priority, the ranking corresponding to the maximum total benefit value will be taken as the preferred ranking; if the selected heating priority strategy is total time priority, the ranking corresponding to the minimum total time will be taken as the preferred ranking; if the selected heating priority strategy is total energy consumption priority, the ranking corresponding to the minimum total energy consumption will be taken as the preferred ranking.

[0059] The aluminum rod heating furnace calculates the preheating time, the preheating waiting time and the total benefit value, and selects the preferred sorting from the initial sorting and the new sorting according to the total benefit value, the total time and the total energy consumption of each sorting and the heating priority strategy selected by the user. According to the preferred sorting, the sorting of the aluminum rods to be heated on the feeding conveying mechanism is adjusted and the action of the feeding conveying mechanism is controlled to convey the aluminum rods to be heated to the preheating section. It can heat multiple aluminum rods of different types and sizes according to the aluminum rod heating strategy selected by the user, and can meet the different aluminum rod heating strategy requirements of the user, solving the problem that the existing heating furnace cannot meet the different aluminum rod heating strategy requirements of the user.

[0060] The present invention also provides a control method for an aluminum rod heating furnace, which is applied to the aluminum rod heating furnace. Figure 1 As shown, it includes the following steps:

[0061] S1, obtaining the types and initial sorting of the aluminum bars to be heated on the feeding conveying mechanism.

[0062] S2, obtaining preheating temperature data of the preheating section and heating temperature data of the heating section.

[0063] S3, obtaining multiple different new sortings according to preset rules and the initial sorting.

[0064] S4, obtaining the preheating time, preheating waiting time, heating time and heating energy consumption of each aluminum bar to be heated in each sort according to the aluminum bar type, initial sort and new sort.

[0065] Specifically, the preheating time is calculated according to the type, mass, initial temperature, preheating temperature and air temperature of the aluminum rod to be heated, and the preheating waiting time is calculated according to the heating time.

[0066] The heating time is calculated according to the type, mass and preheating temperature of the aluminum rod to be heated and the flame temperature of the heating section. Preferably, for an aluminum rod to be heated of a certain type and a certain mass, the gas flow rate and air flow rate of the burner in the heating section are maintained within a preset flow rate range to ensure that the flame temperature of the heating section is stable within a preset temperature range. In this way, not only can the aluminum rod to be heated be stably heated at a suitable flame temperature and the heating quality be improved, but the calculation of the heating time can also be facilitated.

[0067] The heating time can be obtained by calculating the average heating time of heated aluminum bars of the same type and mass. Similarly, the heating energy consumption can also be obtained by calculating the average heating energy consumption of heated aluminum bars of the same type and mass.

[0068] After calculating the heating time and preheating time of each aluminum bar to be heated, the preheating waiting time of each aluminum bar to be heated can be calculated according to the order of the aluminum bars to be heated. It should be noted that the preheating waiting time refers to the time between when the aluminum bar to be heated completes preheating and enters the heating section in the preheating section.

[0069] As a preferred technical solution, a virtual model of an aluminum rod heating furnace can also be constructed based on digital twin technology, and information such as aluminum rod type, quality, initial temperature, preheating temperature, heating temperature, initial sorting, new sorting, and flame temperature of the heating section can be input into the virtual model of the aluminum rod heating furnace to obtain the preheating time, preheating waiting time, heating time, and heating energy consumption of each aluminum rod to be heated in each sorting. Since constructing a virtual model based on digital twin technology is a conventional technical means, it will not be described in detail here.

[0070] S5, calculate the preheating benefit value according to the preheating time, the preheating waiting time and the preheating benefit function, calculate the heating benefit value according to the heating time, the heating energy consumption and the heating benefit function, calculate the total benefit value of each sort according to the preheating benefit value and the heating benefit value, calculate the total time of each sort according to the preheating time, the preheating waiting time and the heating time, and calculate the total energy consumption of each sort according to the heating energy consumption.

[0071] Preferably, the preheating benefit function is , the heating benefit function ;

[0072] in, represents the preheating benefit value, represents the heating benefit value, represents the warm-up time benefit factor, represents the heating time benefit factor, represents the heating energy efficiency factor, represents a natural constant, Indicates the warm-up time. Indicates the warm-up waiting time. represents the first preheating benefit adjustment coefficient and the second preheating benefit adjustment coefficient respectively, Indicates the heating time. Indicates heating energy consumption, They respectively represent the first heating benefit adjustment coefficient and the second heating benefit adjustment coefficient.

[0073] S6, select the preferred sorting from the initial sorting and the new sorting according to the total benefit value, total time and total energy consumption of each sorting and the heating priority strategy selected by the user, adjust the sorting of the aluminum bars to be heated on the feeding conveying mechanism according to the preferred sorting and control the action of the feeding conveying mechanism to convey the aluminum bars to be heated to the preheating section.

[0074] The total benefit value ;in, Indicates the total number of aluminum bars to be heated on the feed conveyor mechanism. Indicates The preheating benefit value of the aluminum bar to be heated, Indicates The heating efficiency value of the aluminum rod to be heated.

[0075] By calculating the total benefit value, total time and total energy consumption of each sorting, and selecting the corresponding sorting as the preferred sorting based on the heating priority strategy selected by the user, such as the manufacturer, the different aluminum rod heating strategy requirements of the user can be met.

[0076] That is to say, the aluminum rod heating furnace calculates the preheating time, preheating waiting time and total benefit value, and selects the preferred sorting from the initial sorting and the new sorting according to the total benefit value, total time and total energy consumption of each sorting and the heating priority strategy selected by the user, adjusts the sorting of the aluminum rods to be heated on the feeding conveying mechanism according to the preferred sorting, controls the action of the feeding conveying mechanism, and conveys the aluminum rods to be heated to the preheating section. It can heat multiple aluminum rods of different types and sizes according to the aluminum rod heating strategy selected by the user, and can meet the different aluminum rod heating strategy requirements of the user, solving the problem that the existing heating furnace cannot meet the different aluminum rod heating strategy requirements of the user.

[0077] The present invention also provides a computer-readable storage medium storing a computer program, which implements the heating furnace control method when the computer program is executed.

[0078] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
