Description

Technical Field

[0001] This application relates to the field of ingot internal defect detection technology, and in particular to an auxiliary detection device for internal defects in smelting ingots. Background Technology

[0002] During the smelting process, metal ingots may develop a variety of internal defects. The formation of these defects is often related to factors such as smelting process, material quality, and operating procedures. Common internal defects include porosity, which is a void formed when gas in the molten metal is not completely expelled during solidification; inclusions, which refer to substances formed inside the ingot, which can be impurities in the molten metal or unmelted local metal; as well as shrinkage cavities, cracks, and chemical segregation.

[0003] Currently, measures taken to reduce internal defects in metal smelting ingots include improving smelting quality, optimizing casting processes, improving mold design, and strengthening cooling control. However, even after reducing internal defects, to ensure the quality of the ingot and the finished product, it is usually necessary to inspect its internal structure after smelting and forming to rule out any remaining defects and guarantee the quality of the formed ingot.

[0004] Currently, flaw detectors are used to detect internal defects in ingots. Their usage is described in the instruction manual attached. Figure 1 As shown, the flaw detector probe is held close to the surface of the ingot by hand for detection, and real-time observation is performed via a cable-connected display screen. This allows for the detection of internal defects in the ingot (primarily shrinkage cavities, caused by the large liquid volume and small solid volume of titanium and titanium alloys, resulting in shrinkage cavities due to the volume difference created by the final solidification of the liquid portion during the ingot's solidification process, which is not filled by liquid). Currently, during inspection, the flaw detector probe is typically moved manually circumferentially and axially around the ingot's surface to achieve a complete inspection of the ingot's internal structure. However, due to human error, the probe movement is usually not linear, resulting in deviations. Figure 2 As shown, during the circumferential movement detection of the probe, there will be an axial positional deviation of the probe, resulting in undetected areas between axially adjacent detection positions. Figure 2 As shown in the dotted circle in the middle, when replacing adjacent axial detection positions, it is not possible for the manual operator to accurately move the probe to the next detection position. There may be non-overlapping areas between adjacent detection positions, which in turn may result in missed detection areas, leading to incomplete detection of the internal structure of the ingot. Summary of the Invention

[0005] To address the aforementioned problems, this application aims to provide an auxiliary detection device for internal defects in smelting ingots. This device can securely assemble the probe, thereby mitigating the influence of human instability during the detection process. It can also drive the probe to move axially and circumferentially, enabling complete detection of internal defects in the ingot and ensuring the forming quality of the ingot and subsequent processed products.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: an auxiliary detection device for internal defects of smelting ingots, including a flaw detector, which consists of a probe and a display, characterized in that: the detection device further includes a detection bracket set on the ingot, the probe is mounted on the detection bracket, and the detection bracket is provided with a driving component that drives the probe to move axially and circumferentially.

[0007] Preferably, the detection bracket is circumferentially fitted onto the ingot, and the detection bracket is a hinged and openable clamp structure.

[0008] Preferably, the driving component includes a circumferential slide bar perpendicular to the detection bracket and circumferentially slidable at one end on the detection bracket, and an axial slide plate slidably disposed on the circumferential slide bar and fitted with the probe.

[0009] Preferably, a displacement scale is provided along the entire length of the circumferential slide bar, and a locking bolt is provided on one side of the axial slide plate to position it with the circumferential slide bar.

[0010] The beneficial effects of this application are: the detection device assembles and fixes the probe by means of a detection bracket, which can achieve a relatively stable state between the probe and the ingot compared with the current manual hand-held method, thereby solving the influence of human instability factors during the detection process.

[0011] By driving the probe to move circumferentially on the detection bracket through the driving component, a complete circumferential inspection of the ingot can be performed. By moving axially, after the inspection of a single circumferential inspection position is completed, it can move to the next circumferential inspection position. In this way, a complete inspection of internal defects of the ingot can be completed, ensuring the forming quality of the ingot and subsequent processed products. Attached Figure Description

[0017] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] See attached document Figures 1-4 The illustrated auxiliary detection device for internal defects in smelting ingots includes a flaw detector, which consists of a probe 11 and a display 12. Specific detection methods include... Figure 1 As shown, the display 12 is placed on the surface of the ingot, and then the probe 11 is held close to the surface of the ingot for detection. Real-time observation is performed via a cable-connected display screen, thus completing the detection of internal defects in the ingot. To address the problem of incomplete detection due to unstable factors during manual inspection, this application includes a detection device, such as... Figure 4 As shown, it includes a detection bracket 2 set on the ingot, and the probe 11 is mounted on the detection bracket 2. Compared with the current manual hand-held method, the detection bracket 2 can make the probe 11 relatively stable with the ingot, thereby solving the influence of human instability during the detection process.

[0019] After the probe 11 is mounted on the detection bracket 2, to facilitate the movement and detection of the probe 11, such as... Figure 4 As shown, a driving component is provided on the detection bracket 2 to drive the probe 11 to move axially and circumferentially. When the probe 11 is driven to move circumferentially on the detection bracket 2 by the driving component, a complete circumferential inspection of the ingot can be performed; while by axial movement, after the inspection of a single circumferential inspection position is completed, it can move to the next circumferential inspection position. In this way, a complete inspection of internal defects of the ingot can be completed, ensuring the forming quality of the ingot and subsequent processed products.

[0020] like Figure 3-4 As shown, the detection bracket 2 is a circular ring structure adapted to the ingot, with its circumferential ring fitting onto the ingot. The detection bracket 2 is also a hinged, openable clamp structure. Because the surface of the smelted ingot is relatively rough, it is difficult to smoothly insert the closed-ring detection bracket 2 from the end of the ingot. Therefore, it is designed as an openable clamp structure, facilitating the smooth insertion of the detection bracket 2 at any position on the circumference of the ingot.

[0021] Specifically, such as Figure 3-4As shown, the driving component includes a circumferential slide rod 3 perpendicular to the detection bracket 2 and circumferentially slidable at one end on the detection bracket 2, and an axial slide plate 4 slidably mounted on the circumferential slide rod 3 and fitted with the probe 11. The circumferential slide rod 3 and the detection bracket 2 are connected by a groove structure, allowing the circumferential slide rod 3 to slide circumferentially on the detection bracket 2. The probe 11 is preferably fitted to one side of the axial slide plate 4 by binding or using connecting bolts, such as... Figure 4 The position shown allows the probe 11 to be positioned outside the axial slide plate 4, avoiding interference from the axial slide plate 4 on the bottom detection surface of the probe 11. To prevent the axial slide plate 4 from rotating circumferentially on the circumferential slide rod 3, the circumferential slide rod 3 is preferably square or rectangular in cross-section, thus limiting the rotation of the axial slide plate 4 after it is engaged with the slide rod 3.

[0022] After assembly, the circumferential slide bar 3 is driven to slide circumferentially along the detection bracket 2 to achieve a complete circumferential inspection of the current detection position. After the circumferential inspection at this position is completed, the axial slide bar 4 is driven to move circumferentially around the circumferential slide bar 3 (moving a distance less than the length of the probe 11, so that the axial adjacent detection positions partially overlap, avoiding the omission of detection areas between adjacent detection positions). Then, the circumferential slide bar 3 is driven to move circumferentially around the detection bracket 2 to complete the complete circumferential inspection of this detection position. This operation can completely detect internal structural defects in the ingot.

[0023] To further avoid the influence of human factors on the spacing between adjacent detection positions, such as Figure 3 As shown, a displacement scale 3a is provided along the entire length of the circumferential slide bar 3. The position of the probe 11 can be accurately adjusted axially through the displacement scale 3a, avoiding the problem of non-overlapping adjacent detection positions due to insufficient accuracy of manual movement time.

[0024] After adjusting the detection position of probe 11, during the circumferential sliding detection process, to prevent probe 11 from sliding axially on the circumferential slide bar 3, as follows: Figure 3-4 As shown, a locking bolt 5 is provided on one side of the axial slide plate 4 to position it relative to the circumferential slide rod 3. After adjusting the detection position of the probe 11 using the displacement scale 3a, the locking bolt 5 is tightened so that its end abuts against the circumferential slide rod 3, thereby achieving relative positioning between the axial slide plate 4 (probe 11) and the circumferential slide rod 3, thus maintaining the linearity (planarity) of the probe 11's movement during circumferential sliding detection.

[0025] The principle of this application is as follows: When performing internal defect detection of an ingot, the detection bracket 2 is first hinged open and then looped around the starting point of the location to be detected on the surface of the ingot. Next, the probe 11 is mounted on the axial sliding plate 4 and slid along the circumferential sliding rod 3. The detection position of the probe 11 is adjusted, and then the locking bolt 5 is tightened to lock the probe 11 relative to the circumferential sliding rod 3. The circumferential sliding rod 3 is then driven to slide circumferentially on the detection bracket 2, thus completing the circumferential detection of the current location. Then, the locking bolt 5 is loosened, and the position of the probe 11 is adjusted using the displacement scale 3a on the circumferential sliding rod 3, ensuring that the adjusted detection position partially overlaps with the already detected position. The locking bolt 5 is then tightened again to perform the complete circumferential detection operation at that location. In this way, the complete detection of the internal structure of the ingot can be completed.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this application. Various changes and modifications may be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
