Description

Technical Field

[0001] The invention relates to the technical field of zinc liquid slag removal, and in particular to a method for evaluating the polymerization effect of zinc liquid surface slag. Background Art

[0002] The zinc pot is the core equipment of the continuous hot-dip galvanizing production line. The zinc slag produced during the galvanizing process affects the surface quality of the galvanized sheet, and in severe cases, the galvanized sheet product is scrapped. The zinc pot slag removal worker needs to perform the slag removal operation every 40 to 60 minutes. However, the ambient temperature around the zinc pot is high, the operating space is narrow, the workers' work is dangerous, and the labor intensity is high. Manual slag removal can easily cause excessive fluctuations in the liquid level and affect the surface quality of the galvanized sheet. Therefore, it is urgent to develop new technologies to reduce the labor intensity and working environment of workers, reduce excessive fluctuations in zinc liquid, and ensure the quality of galvanized sheets.

[0003] Electromagnetic separation technology uses the principle of the difference in electrical conductivity between the molten metal and the inside of the molten metal to separate inclusions in the molten metal. In the prior art, there is no absolutely effective evaluation method for evaluating the effect of electromagnetic separation technology on zinc slag, whether in the test stage or in the application of production lines.

[0069] In some optional embodiments, referring to Figures 2 to 6 , Figure 2 A sampling diagram of the first sample is shown in FIG. Figure 3 A sampling diagram of the second sample is shown in FIG. Figure 4 This is a metallographic side planing zinc slag comparison diagram of the first sample 112 area and the second sample 112D area. Figure 5 This is a metallographic side planing zinc slag comparison diagram of the first sample 132 area and the second sample 132D area. Figure 6 This is a metallographic side planing zinc slag comparison diagram of the first sample 152 area and the second sample 152D area. The first sample is a sample formed by placing a mixed solution of zinc slag and zinc liquid in a container and solidifying. After the first sample is heated and melted and subjected to electromagnetic slag gathering treatment, it solidifies again in the container to form the second sample. Figure 2 and Figure 3 , the first sample is divided into the left part, the middle part and the right part in the direction of the traveling wave, and samples are taken from the 112D area on the left, the 132D area in the middle and the 152 area on the right. Similarly, samples are taken from the 112 area, the 132 area and the 152 area of ​​the second sample. The 112 area corresponds to the 112D area, the 132 area corresponds to the 132D area, and the 152 area corresponds to the 152D area. Taking the electromagnetic slag gathering treatment to push the zinc slag to the edge of the container as an example, refer to Figures 4 to 6 ,exist Figures 4 to 6In the figure, the upper picture is the metallographic side planing picture of the first sample, and the lower picture is the metallographic side planing picture of the second sample. It can be seen that the amount and area of ​​zinc slag in areas 112 and 152 have increased significantly, while the amount and area of ​​zinc slag in area 132 have decreased significantly, and the shape of the zinc slag is relatively regular and concentrated, which proves the effectiveness of electromagnetic slag treatment.

[0070] Furthermore, referring to Table 1, the influencing factors of electromagnetic slag aggregation treatment are analyzed.

[0071] First, the effect of frequency on slag aggregation was analyzed. The relative aggregation values ​​corresponding to the four frequency levels of 5Hz, 10Hz, 15Hz, and 20Hz were selected with a current of 50A. Through data analysis, it was found that the relative aggregation increased approximately linearly with the increase of frequency. The maximum relative aggregation value was 11.4% in the 11th test, and the minimum relative aggregation value was 3.0% in the 1st test.

[0072] Then, the influence of current on the slag aggregation effect was analyzed. The relative aggregation values ​​corresponding to the 20Hz frequency and the four current levels of 50A, 100A, 150A, and 200A were selected. Through data analysis, it was found that with the increase of current, the relative aggregation showed an approximately linear increase, but the linear slope increased from 0.00066 to 0.00184, indicating that the influence of large current on the relative aggregation is greater. The maximum relative aggregation value was 30.6% in the 20th test, and the minimum relative aggregation value was 11.1% in the 10th test.

[0073] Finally, the influence of the zinc magnetic liquid surface distance on the slag aggregation effect was analyzed. The current was 300A and the frequency was 20Hz. The relative aggregation values ​​corresponding to the three levels of zinc magnetic liquid surface distance were 125mm, 180mm, and 240mm. Through data analysis, it was found that with the increase of the zinc magnetic liquid surface distance, the relative aggregation showed an approximately linear decrease. The maximum relative aggregation value was 30.6% in the 20th test, and the minimum relative aggregation value was 17.4% in the 27th test.

[0074] In other words, frequency, current and zinc-magnetic liquid surface distance are all factors affecting the slag aggregation effect.

[0079] The known influencing factors are frequency, current and zinc-magnetic liquid surface distance. A comprehensive analysis showed that when the frequency is 20 Hz and the current is 300 A, that is, the online operating capacity of the equipment, and the zinc-magnetic liquid surface distance is 125 mm, the zinc slag aggregation effect is best. The surface slag in the zinc ingot shows the characteristic of gathering towards the edge, while the zinc slag in the middle of the zinc ingot is significantly less. During the experiment, the zinc liquid level fluctuation is within a reasonable range and does not exceed 0.5 mm. When the zinc-magnetic liquid surface distance exceeds 180 mm, the zinc slag aggregation effect is not obvious.

[0080] In some optional embodiments, referring to Table 2 and Table 3, the minimum relative aggregation influence factor Q f3 The maximum value is 0.0076, which means that when the frequency increases by the same unit, the larger the basic value of the frequency is, the greater the effect on the aggregation of zinc slag is.

[0081] Minimum relative aggregation factor Q f1 The minimum is 0.0026, which means that when the frequency increases by the same unit, the smaller the basic value of the frequency is, the smaller the effect on the aggregation of zinc slag is, and the less obvious the aggregation effect is.

[0082] Maximum relative aggregation factor Q A3 The maximum is 0.1, which means that when the current increases by the same unit, the larger the basic value of the current is, the greater the effect on the aggregation of zinc slag is.

[0083] Maximum relative aggregation factor Q A2 The minimum is 0.053, which means that when the current increases by the same unit, when the basic value of the current is between 100A and 150A, the effect on the aggregation of zinc slag is smaller and the aggregation effect is less obvious.
