Description

Technical Field

[0001] The invention belongs to the technical field of auxiliary detection of chemical composition of molten steel, and in particular relates to a method for retaining furnace numbers in a chemical analysis process based on the principle of a serial number trace method. Background Art

[0002] The chemical composition of steelmaking molten steel determines the product quality of Baosteel's steel. The spectrometer can quickly detect the chemical composition of molten steel. Steelmaking cake samples are the product of the application of spectral chemical analysis. Steelmaking cake samples play an important role in the detection of chemical composition. In the subsequent proofreading of chemical composition, the chemical composition of steelmaking cake samples is detected by chemical analysis and compared with the results of spectral direct reading. In chemical analysis, steelmaking cake samples require sample chips, which can be drilled, planed or prepared by other methods. During the sampling process, the steelmaking cake samples have a fast cooling speed and high hardness, and cannot be processed during sampling, so heat treatment is used to reduce the hardness for easy processing. There are two traditional printing and marking methods, one is manual, that is, a hammer is used to hit the type head, and the production logo to be marked is marked on the designated position; the other is mechanical, that is, a marking machine is used to print the production logo; relatively speaking, the former has low printing efficiency and certain safety hazards, and the latter is relatively complex in design and has a relatively high manufacturing cost.

[0003] Since the surface of the steelmaking cake sample is relatively small and uneven, and the furnace number has many digits, the surface is not suitable for printing. The steelmaking cake sample is affixed with a paper with the steelmaking furnace number information. During the chemical analysis process, especially the heat treatment process, the paper will burn when it enters the furnace, so the furnace number retention of the steelmaking cake sample is a key technology in the chemical analysis process. The inventor has developed a method for retaining the furnace number of steelmaking cake samples during heat treatment (CN117512309A, hereinafter referred to as document 1), which includes the following steps: 1) Arrange several cake samples, place them on a tray, and take pictures; 2) Copy the furnace numbers of several cake samples on the sample bag and place them in the order of the samples; 3) Put the tray and the sample into the heat treatment furnace for treatment; 4) After the treatment, take out the tray and then cool the sample to room temperature; 5) Put several samples into the sample bag in order; 6) Send several cake samples to the next process. Although the method disclosed in Document 1 can correctly retain the original sample number of steel cake samples with uneven surfaces after heat treatment, it has the following defects in production: (1) The method of Document 1 is suitable for situations where the number of steel cake samples is small, and only a few cake samples can be loaded into one furnace during the heat treatment process. This is because when the number of steel cake samples is large, the probability of incomplete furnace numbers on the removed mouth-take paper increases, making it difficult to distinguish; moreover, the position of steel cake samples without furnace numbers on the material tray cannot be changed. When loading the furnace, if too many cake samples are loaded, the position is easy to move, causing the position of the steel cake samples to change from the position before taking the photo, resulting in confusion of the furnace numbers of the steel cake samples and erroneous results. In addition, when the number of cake samples is large, in order to avoid confusion of cake samples, multiple heat treatments are required, which increases energy consumption, and each additional furnace takes 2 more days, which is inefficient; (2) Document 1 needs to remove the mouth-take paper before heat treatment. The cutting paper on the steel cake sample is firmly bonded and difficult to remove, which will cause the cutting paper to be incomplete when it is removed; and the speed of tearing it off is slow, which will lead to low efficiency. After heat treatment, the torn cutting paper needs to be pasted on the sample again. It may be that the cutting paper is not sticky enough due to repeated use or it is damaged when it is torn off and cannot be pasted on the sample again; (3) After heat treatment, the cake sample in Document 1 is easy to fall off after being placed in the sample bag, which will cause confusion of the cake sample and erroneous results; (4) Since the furnace number is relatively complicated, Document 1 needs to spend a lot of time for each marking, resulting in low efficiency and easy errors in furnace number information. Summary of the invention

[0004] In view of the problems existing in the prior art, the object of the present invention is to provide a method for retaining the furnace number of steelmaking cake samples in the chemical analysis process, which has low fault tolerance, low energy consumption, high efficiency, and can process a large number of steelmaking cake samples at one time, and comprises the following steps:

[0005] S1) Enter the furnace number information on the steel cake sample paper into the computer in sequence, and each furnace number is assigned a sequence number;

[0006] S2) using a marker pen to mark the serial number of the corresponding furnace number on the corresponding steelmaking cake sample, and sending it to a heat treatment furnace for heat treatment;

[0007] S3) Before heat treatment, several steel cake samples are placed on the material tray according to the sequence number, and before loading into the furnace, the several steel cake samples are photographed with a mobile phone, and the order and position of each steel cake sample are retained after loading into the furnace;

[0008] S4) comparing the heat-treated steel cake samples with the photos obtained in step S3), and marking the sequence numbers on the steel cake samples with a marker or a high-temperature pen;

[0009] S5) sending the steelmaking cake samples marked in step S4) to subsequent processes.

[0010] In some embodiments, in step S2), a take-out paper is attached to one side of the steelmaking cake sample, and a corresponding serial number is marked on the take-out paper.

[0011] In some embodiments, the method further comprises the following steps:

[0012] S6) Enter the analysis results of several steelmaking cake samples marked with sequence numbers into a report sheet in the computer, corresponding to their respective furnace number information.

[0013] In some embodiments, the subsequent process in step S5) includes subsequent processing sampling and chemical analysis.

[0014] In some embodiments, before marking the serial numbers on the steelmaking cake samples with a marker pen or a high-temperature pen in step S4), the process also includes removing the easily detachable surface layer of each steelmaking cake sample.

[0015] In some embodiments, in step S3), more than 10, preferably more than 15, and more preferably more than 18 steelmaking cake samples are placed on a tray in sequence and photographed.

[0016] Beneficial effects of the present invention:

[0017] The method provided by the present invention can simplify the complex furnace number into a simple serial number, which is not easy to make mistakes when transferring between various processes, ensures that the steelmaking cake sample and the furnace number are correctly corresponding, and solves the difficulty of the furnace number not being easy to mark during the heat treatment process. As long as the position of the cake sample is correctly recorded, after the heat treatment is taken out of the furnace, the serial number is marked on the cake sample again with a high temperature ratio or a marker, and then transferred to the processing process, drilled or turned into a chip sample, and sent to the chemical room for chemical analysis. Finally, the serial number is restored to the furnace number, and a report sheet is issued according to the furnace number, and the chemical analysis process can be completed. Moreover, the method of the present invention does not need to tear off the mouth paper from the steelmaking cake sample before and after the heat treatment and then paste the mouth paper, and does not need to copy the furnace number information on the sample bag again, which can save a lot of time and improve the efficiency of chemical analysis. In addition, the method of the present invention does not need to put the steelmaking cake sample into the sample bag, so the risk of confusion is avoided, and the simple serial number is less likely to have errors than the complex furnace number information, so the fault tolerance rate of the method of the present invention is low. Furthermore, the method of the present invention can be used to retain the furnace number of a large number of steel-making cake samples. This is because when using the serial number trace method, the serial number is simple and can be marked on both sides of the steel-making cake sample with a high-temperature pen (one side can also be affixed with a mouth-taking paper, and the corresponding serial number is marked on the mouth-taking paper with a marker). The corresponding serial number is also marked on the mouth-taking paper. This is to facilitate the placement of the cake sample on the material tray, and the mouth-taking paper is placed facing up. When taking pictures and loading the furnace, in order to retain the original number, the furnace number entered into the computer can be corrected; when loading the furnace, the surface of the steel-making cake sample is marked with a serial number. Even if the position of the cake sample changes, the position can be restored according to the serial number. Therefore, a large number of steel-making cake samples can be heat-treated each time without confusion, and the work efficiency is high. Moreover, for heat-treated samples with uneven or irregular surfaces and particularly complex sample numbers, the method of the present invention can also be used to simplify the sample number, take pictures of the original number and the sample loading position, and solve the problem of sample number and sample correspondence. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 These are photos of 18 steel cake samples before heat treatment.

[0019] Figure 2 This is a photo of 18 steelmaking cake samples after re-marking serial numbers after heat treatment. DETAILED DESCRIPTION

[0020] During the heat treatment process, the treatment temperature is high, and the paper on the surface of the steel cake sample is burned. After the steel cake sample is taken out of the furnace, it is impossible to distinguish it. This requires that the furnace order of the steel cake sample be recorded before loading, and the position of the steel cake sample is kept unchanged after loading. After taking out of the furnace, the furnace number of the steel cake sample is restored according to the position. It is required that the furnace number of the steel cake sample be marked before the heat treatment of the steel cake sample in order to distinguish it and place it in order.

[0021] The present invention enters all the steelmaking numbers (furnace numbers) on the steelmaking cake sample paper into the computer according to the production date or the production process sequence, automatically generates a serial number (also referred to as the serial number in this article), writes the serial number on the surface of each steelmaking cake sample with a high-temperature pen, and sends it to the heat treatment process for softening treatment. During the heat treatment process, the steelmaking cake samples are placed on the iron plate (material tray) in the order of the serial numbers, and the arranged steelmaking cake samples are photographed, and the placement order of the steelmaking cake samples and the original appearance of the steelmaking cake samples are retained (for comparison after leaving the furnace); slowly put into the heat treatment furnace, and try not to change the position of the steelmaking cake samples. After the heat treatment is completed, the surface layer of the steelmaking cake sample that is easy to fall off is processed, and the traces of the serial number marked with a high-temperature pen on the steelmaking cake sample are compared with the photos or the traces of the serial number marked with a high-temperature pen on the steelmaking cake sample, and the serial number is re-marked with a high-temperature pen or a marker. The numbered steelmaking cake samples are sent to the subsequent processing sampling and chemical analysis process, and a report sheet is issued according to the furnace number after the inspection results come out.
