Description

Technical Field

[0001] The invention relates to the technical field of scrap steel quality detection, in particular to a method for evaluating the quality of scrap steel briquetting. Background Art

[0002] Scrap briquettes are made by compressing scrap, including discarded steel, from various types of machinery and equipment, vehicles, agricultural machinery, tools, building materials, and household items, or scrap, leftovers, and iron-containing waste generated during the production of these products, into briquettes for easier transportation and use. While briquetted scrap is convenient for transportation and use, buyers can only inspect the surface quality of the briquetted scrap during quality inspection, making it easier for suppliers to pass off inferior products as genuine ones and making quality inspection more difficult for buyers.

[0003] At present, the inspection of scrap steel briquettes in the market is mostly to select briquettes and then decompose them from the middle of the briquettes for inspection. There is no relatively complete quality evaluation method, which brings about the following disadvantages: first, if they are only decomposed from the middle, illegal suppliers may hide inferior materials or other fraudulent behaviors in some parts (head and tail), causing direct economic losses to the purchaser; second, when fraudulent behaviors such as passing inferior products off as good ones are discovered, there is no quality evaluation and handling standard, which makes it easy for the supply and demand parties to have disputes and non-compliance situations to occur. Summary of the Invention

[0004] In order to overcome the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a method for evaluating the quality of scrap steel briquette.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a method for evaluating the quality of scrap steel briquetting, comprising the following steps:

[0006] Randomly sample the scrap steel briquettes loaded on the vehicles to be assessed, and determine the decomposition position of each sampled scrap steel briquettes by random drawing;

[0007] Cut the sampled scrap steel briquettes according to the determined decomposition parts, and after the cutting is completed, collect and weigh the total weight of the ash residue generated after cutting all the sampled scrap steel briquettes in each car;

[0008] The total weight of the ash obtained by weighing is compared with the set ash standard range one by one. According to the comparison results, the quality standard range to which the vehicle scrap steel briquettes to be evaluated belong is judged, and the quality grade of the vehicle scrap steel briquettes to be evaluated is determined.

[0009] As a further improvement of the present invention: the specific rating rules are as follows:

[0010] If the total weight of ash and slag is within the set minimum standard range, the vehicle scrap steel briquettes are judged to be of qualified grade;

[0011] If the total weight of ash exceeds the qualified standard range, different abnormal quality levels corresponding to the degree of excess will be determined, and corresponding treatment will be carried out in accordance with the established quality abnormality evaluation and treatment standards.

[0012] As a further improvement of the present invention, before randomly sampling the scrap steel briquettes of the vehicle to be evaluated, the following steps are further included:

[0013] Conduct additional spot checks on scrap steel briquettes at different locations on the bottom of each vehicle. If any of the following situations occur, it will be considered a hidden collision and the unloading of scrap steel briquettes on that vehicle will be stopped;

[0014] 1) Inspect the appearance of the vehicle bottom briquettes to check whether there are obvious ash marks, abnormal color or texture differences on the surface of the briquettes, and determine the grade of the vehicle bottom briquettes. When it is detected that the proportion of low-grade briquettes to the total number of briquettes sampled on the bottom of the vehicle exceeds a first preset proportion;

[0015] 2) Use a cutting machine or an oxygen gun to cut, collect and weigh the ash produced by cutting, use an X-ray fluorescence spectrometer to analyze the composition of the ash sample, compare it with the known ash composition standard spectrum, and determine whether the ash is an impure substance. When it is detected that the weight of the impure ash in the underbody sampled briquettes accounts for a proportion of the total weight of the sampled briquettes that exceeds a second preset proportion.

[0016] As a further improvement of the present invention: the decomposition parts are specifically divided as follows:

[0017] 1 / 4 area: Divide the briquette into four equal parts along the length direction, and the first quarter area close to one end of the briquette;

[0018] 1 / 2 part: measured from one end of the briquette to the position where the briquette is half of its length, and the area formed by extending 5%-10% of the briquette length to both sides with this position as the center;

[0019] 3 / 4 part: along the length direction of the briquette, starting from one end to three-quarters of the length, with this point as the center and extending to both sides by 5%-10% of the briquette length.

[0020] As a further improvement of the present invention, the random lottery to determine the decomposition position of each scrap steel briquette also includes thermal imaging detection, specifically as follows:

[0021] Data acquisition: Use a high-precision thermal imager to fully scan the scrap steel briquette, obtain the temperature distribution image of the briquette surface, and record the scanning time, ambient temperature, and thermal imager parameter settings;

[0022] Feature extraction and analysis: Extract characteristic parameters of temperature distribution from thermal imaging images. These parameters include temperature gradient, high-temperature area, and low-temperature area distribution. By comparing these parameters with standard thermal imaging feature models, it is determined whether there are any inhomogeneities, defects, or impurities inside the compact.

[0023] Quality determination and report generation: Based on the results of thermal imaging analysis and the quality rating of scrap steel briquettes obtained through random inspections, the comprehensive quality grade of the scrap steel briquettes is determined and a thermal imaging analysis report is generated. The report includes the thermal imaging image of the briquettes, characteristic parameter analysis results and quality determination conclusions, and is entered into the supplier's integrity file.

[0024] As a further improvement of the present invention: further comprising:

[0025] Mark areas with significantly higher or lower temperatures as suspected abnormal areas and record their corresponding locations and temperature characteristics;

[0026] If the suspected abnormal part detected by thermal imaging coincides with the randomly determined decomposition part, the spot check will be focused on that part; if they do not coincide, the suspected abnormal part and the randomly determined decomposition part will be spot checked separately.

[0027] As a further improvement of the present invention: further comprising:

[0028] The temperature distribution information and abnormal part characteristics obtained by thermal imaging detection are integrated and analyzed with the internal structure problems and total ash weight data found in the random inspection of decomposition parts;

[0029] Establish a data fusion model, assign corresponding weights to the above different types of data, and comprehensively evaluate the quality of scrap steel briquettes;

[0030] According to the comprehensive analysis results, the quality grade of the scrap steel briquettes is determined by comparing with the pre-set quality rating range. The quality grades can be divided into high-quality, qualified, downgraded and unqualified.

[0031] As a further improvement of the present invention: the determination of the abnormal quality level includes:

[0032] If the percentage of excess is between 1% and 5% (inclusive), it is judged as a mild abnormal quality level; if the percentage of excess is between 5% and 10% (inclusive), it is judged as a moderate abnormal quality level; if the percentage of excess is greater than 10%, it is judged as a severe abnormal quality level.

[0033] As a further improvement of the present invention: further comprising:

[0034] Establish a scrap steel briquette quality traceability information database, and enter all relevant information of each scrap steel briquette sampled into the database. The relevant information of the scrap steel briquette includes the sub-area identification of the carriage where the scrap steel briquette is located, the sampling number, the ash weight and quality, as well as the related supplier information, production batch information, and transportation link information.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] Random sampling of scrap steel briquettes from the vehicles under assessment can avoid human interference. A random lottery determines the decomposition site of each scrap steel briquette, enhancing the randomness of the test. After cutting the scrap steel briquettes according to their decomposition site, the total weight of the ash residue generated by all scrap steel briquettes from each vehicle is collected and weighed. This converts the quality of the scrap steel briquettes into a specific quantitative indicator, eliminating the uncertainty of subjective judgment. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Figure 2 This is a schematic diagram of the decomposition parts in a method for evaluating the quality of scrap steel briquette according to the present invention. DETAILED DESCRIPTION

[0039] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] In order to solve the technical problems in the prior art, the present invention is further described with reference to the accompanying drawings and embodiments:

[0041] The embodiment of the present invention discloses a method for evaluating the quality of scrap steel briquetting, comprising the following steps:

[0042] The scrap steel briquettes loaded on the vehicles to be evaluated are randomly sampled, and the decomposition position of each sampled scrap steel briquettes is determined by random drawing; the sampled scrap steel briquettes are cut according to the determined decomposition position, and after the cutting is completed, the total weight of the ash produced after the cutting of all the sampled scrap steel briquettes on each vehicle is collected and weighed; the total weight of the ash obtained by weighing is compared one by one with the set ash standard range, and based on the comparison result, the quality standard range to which the scrap steel briquettes of the vehicles to be evaluated belong is judged, and the quality grade of the scrap steel briquettes of the vehicles to be evaluated is determined.

[0043] Random sampling ensures comprehensiveness: Random sampling of scrap steel briquettes from the vehicles being evaluated eliminates human interference, ensuring that the sample is more representative of the quality of the entire batch. Every briquette has an equal chance of being selected, encompassing briquettes from different locations and with varying characteristics, providing a more comprehensive and accurate data foundation for subsequent quality evaluation.

[0044] Randomly selecting the decomposition location increases uncertainty: By randomly selecting the decomposition location for each scrap steel briquette, the randomness of the test is further enhanced. Different decomposition locations may exhibit different quality characteristics. Random selection allows for a more comprehensive assessment of the internal quality of the briquette, preventing bias caused by focusing on specific locations and ensuring that the evaluation results better reflect the true quality of the scrap steel briquette.

[0045] Total ash weight is a quantitative quality indicator: After cutting the scrap briquettes according to their decomposition area, the total ash weight generated by each truckload of scrap briquettes is collected and weighed, transforming the quality of the scrap briquettes into a specific quantitative indicator. Total ash weight is an intuitive and easily measurable physical quantity. This method allows the quality of the scrap briquettes to be digitally expressed, eliminating the uncertainty of subjective judgment.

[0046] In some implementations, the specific rating rules are as follows:

[0047] If the total weight of ash and slag is within the set minimum standard range, the vehicle scrap steel briquettes are judged to be of qualified grade;

[0048] If the total weight of ash exceeds the qualified standard range, different abnormal quality levels corresponding to the degree of excess will be determined, and corresponding treatment will be carried out in accordance with the established quality abnormality evaluation and treatment standards.

[0049] The determination of abnormal quality level includes:

[0050] If the percentage of excess is between 1% and 5% (inclusive), it is judged as a mild abnormal quality level; if the percentage of excess is between 5% and 10% (inclusive), it is judged as a moderate abnormal quality level; if the percentage of excess is greater than 10%, it is judged as a severe abnormal quality level.

[0051] In practical operation, the following quality abnormality evaluation and handling standards can be set:

[0052] (1) Identification and handling of quality abnormalities

[0053] a. If there are two scrap steel briquettes with obvious discrepancies between the inner and outer shapes, and the inner shape is two grades or more lower than the surface shape and >30%, they will be judged as the lowest grade among the actual objects and will be fined RMB 30,000 per vehicle.

[0054] b. Concealed loading, with low-grade briquettes or mixed ash slag mixed on the bottom of the vehicle, will be judged according to the lowest grade of the actual objects and will be subject to an economic penalty of RMB 30,000 per vehicle.

[0055] (2) Major quality abnormalities and their treatment methods

[0056] a. If only one piece of briquetting contains ash packed in a barrel or bag, and the weight of the ash exceeds 20kg, it will be settled at only RMB 1 per ton, and an economic penalty of RMB 100,000 per vehicle will be imposed.

[0057] b. If there are two or more pieces of briquetting and the ash is packed in barrels or bags (the amount of ash is not measured), the settlement will be based on only 1 yuan per ton, and an economic penalty of 200,000 yuan per vehicle will be imposed.

[0058] c. One truck was decomposed into 5 pieces, and the total amount of ash was found to be between 100-200kg, and the settlement was 1 yuan / ton.

[0059] d. One truck was decomposed into 5 pieces, and the total amount of ash was found to be between 201kg and 400kg. It was settled at only 1 yuan per ton, and an economic penalty of 100,000 yuan per truck was imposed.

[0060] e. One truck was decomposed into 5 pieces, and the total amount of ash was found to be between 401kg and 1200kg. The settlement was only 1 yuan per ton, and an economic penalty of 200,000 yuan per truck was imposed.

[0061] f. A car was decomposed into 5 pieces, and the total amount of ash was found to be more than 1,200 kg. It was settled at only 1 yuan per ton, and an economic penalty of 300,000 yuan per car was imposed.

[0062] (3) Identification and handling of fraudulent purchases of scrap steel

[0063] If there are more than three cars of briquettes with serious quality abnormalities delivered to the factory on the same day with the same order contract number, it will be deemed as fraud and an additional economic penalty of 100,000 yuan per car will be imposed.

[0064] In some embodiments, Figure 1 and Figure 2 As shown in the figure, a represents length, b represents width, c represents height, label ① represents 1 / 4 part, label ② represents 1 / 2 part, label ③ represents 3 / 4 part, and the decomposed parts are specifically divided as follows:

[0065] 1 / 4th position: Divide the briquette into four equal parts along its length. The first quarter near one end of the briquette is the 1 / 4th decomposition position. Selecting this decomposition position is effective for detecting whether the ends of the briquette are wrapped with inferior materials, as the ends are more likely to harbor impurities during the briquette production process.

[0066] 1 / 2 position: Measure from one end of the compact to the point halfway along its length. The area formed by extending a certain distance to either side of this point (this distance is determined by the actual size of the compact and the required test accuracy, generally 5%-10% of the compact length) is the 1 / 2 decomposition point. Testing this area can reveal the quality of the midsection of the compact and determine whether there is any overall uneven quality.

[0067] 3 / 4 position: Also along the length of the briquette, starting from one end to three-quarters of the length, and extending a certain distance in both directions from this point (the extension distance is determined in the same way as the 1 / 2 position), this area is the 3 / 4 decomposition position. This position can detect the quality of the other end of the briquette and the area near the end, complementing the 1 / 4 position to fully cover potential quality risks at both ends of the briquette.

[0068] In some embodiments, before randomly sampling the scrap steel briquettes of the vehicle to be evaluated, the method further includes:

[0069] Conduct additional spot checks on scrap steel briquettes at different locations on the bottom of each vehicle. If any of the following situations occur, it will be considered a hidden collision and the unloading of scrap steel briquettes on that vehicle will be stopped;

[0070] 1) Inspect the appearance of the vehicle bottom briquettes to check whether there are obvious ash marks, abnormal color or texture differences on the surface of the briquettes, and determine the grade of the vehicle bottom briquettes. When it is detected that the proportion of low-grade briquettes to the total number of briquettes sampled on the bottom of the vehicle exceeds a first preset proportion;

[0071] 2) Use a cutting machine or an oxygen gun to cut, collect and weigh the ash produced by cutting, use an X-ray fluorescence spectrometer to analyze the composition of the ash sample, compare it with the known ash composition standard spectrum, and determine whether the ash is an impure substance. When it is detected that the weight of the impure ash in the underbody sampled briquettes accounts for a proportion of the total weight of the sampled briquettes that exceeds a second preset proportion.

[0072] In some embodiments, the random drawing to determine the decomposition location of each scrap steel briquette also includes thermal imaging testing, as follows:

[0073] Data acquisition: Use a high-precision thermal imager to fully scan the scrap steel briquette, obtain the temperature distribution image of the briquette surface, and record the scanning time, ambient temperature, and thermal imager parameter settings;

[0074] Feature extraction and analysis: Extract characteristic parameters of temperature distribution from thermal imaging images. These parameters include temperature gradient, high-temperature area, and low-temperature area distribution. By comparing these parameters with standard thermal imaging feature models, it is determined whether there are any inhomogeneities, defects, or impurities inside the compact.

[0075] Quality determination and report generation: Based on the results of thermal imaging analysis and the quality rating of scrap steel briquettes obtained through random inspections, the comprehensive quality grade of the scrap steel briquettes is determined and a thermal imaging analysis report is generated. The report includes the thermal imaging image of the briquettes, characteristic parameter analysis results and quality determination conclusions, and is entered into the supplier's integrity file.

[0076] The uneven structure and composition of scrap briquettes can lead to varying heat transfer characteristics. When heating or cooling, areas containing voids, foreign matter, or varying material distribution can produce surface temperature distributions that differ from those found elsewhere. Thermal imagers can detect these subtle temperature differences and convert them into visual thermal images, providing a basis for assessing scrap briquette quality.

[0077] Image processing and machine learning algorithms are used to extract characteristic temperature distribution parameters from thermal images, such as temperature gradient, high-temperature area, and low-temperature distribution. By comparing these parameters with standard thermal imaging feature models, the presence of internal inhomogeneities, defects, or impurities within the compact can be determined. For example, areas with large cavities or foreign material inclusions may exhibit abnormal temperature distribution.

[0078] In some embodiments, the present invention further comprises:

[0079] Mark areas with significantly higher or lower temperatures as suspected abnormal areas and record their corresponding locations and temperature characteristics;

[0080] If the suspected abnormal part detected by thermal imaging coincides with the randomly determined decomposition part, the spot check will be focused on that part; if they do not coincide, the suspected abnormal part and the randomly determined decomposition part will be spot checked separately.

[0081] In some embodiments, the present invention further comprises:

[0082] The temperature distribution information and abnormal part characteristics obtained by thermal imaging detection are integrated and analyzed with the internal structure problems and total ash weight data found in the random inspection of decomposition parts;

[0083] Establish a data fusion model, assign corresponding weights to the above different types of data, and comprehensively evaluate the quality of scrap steel briquettes;

[0084] According to the comprehensive analysis results, the quality grade of the scrap steel briquettes is determined by comparing with the pre-set quality rating range. The quality grades can be divided into high-quality, qualified, downgraded and unqualified.

[0085] In some embodiments, the present invention further comprises:

[0086] Establish a scrap steel briquette quality traceability information database and enter all relevant information of each scrap steel briquette sampled into the database. The relevant information of the scrap steel briquette includes the carriage sub-area identification of the scrap steel briquette, sampling number, ash weight and quality, and related supplier information, production batch information, and transportation link information.

[0087] In summary, after reading the present invention document, ordinary technicians in this field can make various other corresponding transformation schemes based on the technical solutions and technical concepts of the present invention without creative mental work, and all of them fall within the scope of protection of the present invention.
