Description

Technical Field

[0001] This invention relates to the field of silicon-adding agent detection technology, specifically to a silicon-adding agent testing device. Background Technology

[0002] Silicon-reinforcing agents play multiple roles in steel production, including deoxidation, alloying, improving casting performance, enhancing heat and corrosion resistance, controlling grain size, and reducing costs. They are indispensable additives in steel production. Current testing and analysis utilizes a chemical analysis method involving perchloric acid dehydration and gravimetric analysis. This method involves melting, filtration, washing, ignition, treatment, and re-ignition, which is time-consuming and cumbersome, requiring a high level of technical expertise. Even slight errors necessitate retesting, making it unsuitable for production batching guidance. Furthermore, the large number of existing crucibles requires manual placement on trays, which is inconvenient and the spacing requires a certain level of technical skill, impacting efficiency. To address this, a fluorescence instrument analysis method has been developed. Standard sample calibration ensures accuracy while improving analytical timeliness, thus providing faster guidance for production batching. Summary of the Invention

[0003] The purpose of this invention is to solve the problems of the current testing and analysis of the device, which uses chemical analysis and perchloric acid dehydration gravimetric method. The analysis process involves melting, filtration, washing, ignition, treatment and re-ignition, which is time-consuming and cumbersome. It requires a high level of technical expertise and requires retesting if the error is slight. It is not suitable for production batching guidance. In addition, the existing large number of crucibles need to be manually placed in various positions on the tray, which is troublesome and the spacing between them requires a certain level of technical expertise, affecting the efficiency of use. Therefore, a testing device for silicon-enhancing agents is proposed.

[0004] To achieve the above objectives, the present invention provides the following technical solution: Design a testing device for silicon-adding agents, including a high-temperature chamber and a testing machine. The outer wall of the high-temperature chamber is fixedly connected to an electric push rod via a connecting bracket. A lifting bracket is fixedly connected to the end of the output shaft of the electric push rod. A rotary motor is installed at the upper end of the lifting bracket. A chamber cover is fixedly connected to the inner wall of the lower end of the lifting bracket. A rotating component is arranged below the chamber cover. A testing component is installed inside the testing machine.

[0005] This setup uses an electric actuator to control the top support and rotating support to be pulled out from inside the high-temperature chamber, thus completing the storage and retrieval of the crucible on the rotating support.

[0006] Preferably, the rotating assembly includes a top bracket, a box cover is fixedly connected to the upper end of the top bracket, the inner wall of the top bracket is rotatably connected to the rotating part of the rotating bracket through a bearing, the multiple inner walls of the rotating bracket are all machined with tapered holes, a gear one is fixedly connected to the upper part of the outer wall of the rotating part of the rotating bracket, a gear two is meshed and connected to the rear side of the outer wall of the gear one, and the inner wall of the gear two is fixedly connected to the output shaft of the servo motor.

[0007] This feature allows the user to control the servo motor to drive gear one and gear two to rotate the rotating bracket slowly during the process of placing or removing the crucibles, thus enabling multiple crucibles to be arranged in a circle on the rotating bracket.

[0008] Preferably, the main body of the servo motor is fixedly connected to the upper rear side of the cover, and the outer wall of the output shaft of the servo motor is rotatably connected to the cover via bearings. Preferably, crucibles are placed in the conical holes on the surface of the rotating bracket. This arrangement allows the crucibles to be accurately and stably placed on the surface of the rotating bracket through the conical holes.

[0009] Preferably, a fan is fixedly connected to the end of the output shaft of the rotary motor, and a heating grid is fixedly connected to the inner wall of the high-temperature chamber.

[0010] This design allows for the placement of a rotating motor and fan above the rotating support, enabling airflow to cool the crucible being removed.

[0011] Preferably, the detection assembly includes a display screen, a cross-shaped moving mechanism, and a turntable. The cross-shaped moving mechanism is installed on the inner wall of the detection machine, and a detection head is installed on the moving part of the cross-shaped moving mechanism. The turntable is located below the detection head, and the lower end of the turntable is connected to the output shaft of the internal motor of the detection machine. Multiple fluorescent sample boxes are fixedly connected to the upper end of the turntable, and the display screen is fixedly connected to the upper part of the inner wall of the detection machine.

[0012] This setting involves placing the fused sheet into the fluorescent sample box, then placing it into the turntable, selecting the corresponding prepared alloy working curves, and using the cross-shaped moving mechanism to drive the detection head to perform point analysis.

[0013] Preferably, a maintenance box is installed on the lower front side of the testing machine, and support feet are fixed to the four corners of the lower end of the testing machine.

[0014] Preferably, an alarm is fixedly connected to the upper front right side of the detection machine.

[0015] The present invention proposes a testing device for silicon-enhancing agents, which has the following advantages: Through the cooperation between the crucible, high-temperature chamber, rotating support, heating grid, detector, and fluorescent sample box, 5.5000g of mixed solvent is weighed and placed into another crucible. The small balls processed above after brushing off the graphite powder are buried in the mixed solvent, 10 drops of release agent are added, and then the crucible is placed inside the high-temperature chamber and melted at 1050°C. After being taken out, it is directly shaped or molded into a measurable glass slide. The prepared molten slide is poured out and placed into the fluorescent sample box, then placed into the turntable. The corresponding prepared working curves of each alloy are selected, and the analysis button is pressed to perform analysis. After the analysis is completed, the instrument displays the analysis results. It has the advantages of improving corrosion resistance, producing smooth and clean slides that are conducive to fluorescence analysis, and having better analytical sensitivity, selectivity, and analysis speed than chemical analysis. It can detect multiple parameters, has a high degree of automation, and has low interference, which is beneficial for guiding production. By coordinating the electric push rod, support, rotating support, high-temperature chamber, rotary motor, and fan, the electric push rod can be controlled to pull the top support and rotating support out of the high-temperature chamber. During the process of placing or removing crucibles, the user can control the servo motor to drive gear one and gear two to slowly rotate the rotating support, allowing multiple crucibles to be arranged in a circle on the rotating support. At the same time, the rotary motor and fan above generate airflow to cool the crucibles being removed. This effectively avoids the problems of manually placing a large number of crucibles in various positions on the tray, which is cumbersome and requires a certain level of technical skill to arrange, thus affecting the efficiency of use.

On the upper rear side, the outer wall of the output shaft of the servo motor 403 is rotatably connected to the cover 8 via a bearing, and crucibles 14 are placed at the conical holes 405 on the surface of the rotating bracket 406.

[0020] See attached document Figure 1-9 In this embodiment, the detection component 3 includes a display screen 301, a cross-shaped moving mechanism 304, and a turntable 305. The cross-shaped moving mechanism 304 is installed on the inner wall of the detection machine 2. The moving part of the cross-shaped moving mechanism 304 is equipped with a detection head 302.

Multiple fluorescent sample boxes 303 are fixedly connected to the upper end of the turntable 305. The display screen 301 is fixedly connected to the upper part of the inner wall of the detection machine 2.

[0021] Working principle: When the testing device for this silicon-adding agent is needed, first arrange the entire device as shown in the figure, then place graphite pits inside multiple crucibles 14, and weigh them in sequence. 1. Place 5000g of mixed solvent (lithium metaborate Li2BO2-lithium tetraborate Li2B4O7), 0.8000g of lithium carbonate (Li2CO3), and 0.2000g of sample on filter paper, stir evenly (finely grind and mix evenly), then shape the filter paper into a cone shape and gently place it into the graphite pit inside the crucible 14. Place the crucible 14 into the rotating support 406, and then control the electric push rod 11 to control the rotating support 406 and the top support 401 to be placed in the high-temperature chamber 1 for heating through the heating grid 13. After the filter paper is completely ashed during the process, press the chamber cover 8 and melt and oxidize at 1000°C for 30-40 minutes. After the sample melts into a small ball without alloying, take it out, let it cool naturally, and gently brush off the graphite powder on the small ball with a small brush.

[0022] 2、 Weigh out 5.5000g of mixed solvent and put it into another crucible 14 (the above crucible has been washed and reused). Embed the small ball after the graphite powder has been brushed off into the mixed solvent and add 10 drops of release agent.

[0023] 3. Then place the crucible 14 into the high-temperature chamber 2 and melt it at 1050°C. The melting time is 120 seconds of holding at the temperature and 960 seconds of melting. Then take it out and directly shape it or cast it into a measurable glass sheet.

[0024] 4. Prepare standard samples into specimens, following the same steps as above, and establish standard curves for the analysis range of each alloy element content.

[0025] 5. After melting, remove the sample sheet and cool it to room temperature. Pour out the prepared molten sheet and label it with the sample code. Place the molten sheet into the fluorescent sample box 302 and then into the turntable 305. Select the corresponding prepared working curves for each alloy and use the cross-moving mechanism 304 to drive the detection head 302 to perform point analysis. After the analysis is completed, the instrument displays the analysis results.

[0026] Compared with existing technologies, this case has the following advantages: 1. The sample undergoes a special pre-oxidation treatment to form a stable oxide film, improving its corrosion resistance; 2. Pre-oxidation treatment avoids the reaction with platinum at high temperatures, thus preventing corrosion of the platinum dish and ensuring a smooth and clean slide for fluorescence analysis. 3. Based on the proportional relationship between fluorescence line intensity and elemental content, establish the matrix standard for each element. Quantitative analysis was performed using a standard curve of element content; 4. At the same time, the instrument's analytical sensitivity, selectivity, and analysis speed are better than chemical analysis. It can detect multiple parameters, has a high degree of automation, and has less interference, which is beneficial for guiding production.

[0027] Specifically, during the process of placing and removing crucibles 14 from the high-temperature chamber 1, the user can control the electric push rod 11 to pull the top support 401 and the rotating support 406 out of the high-temperature chamber 1. Then, during the process of placing or removing crucibles 14, the user can control the servo motor 403 to drive gear one 402 and gear two 404 to drive the rotating support 406 to rotate slowly, so that multiple crucibles 14 are arranged in a circle at the rotating support 406. At the same time, the rotating motor 6 and the fan 15 above generate airflow to cool the crucibles 14 that are being removed. In this way, the problem of manually placing a large number of crucibles in various positions on the tray is avoided, which is troublesome and the spacing requires a certain level of technical skill, affecting the efficiency of use.
