Description

Technical Field

[0001] This invention relates to the field of continuous casting machine guide rail technology, and in particular to a welding method for continuous casting machine guide rails and a continuous casting machine guide rail. Background Technology

[0002] The core function of the continuous casting machine guide rail is to ensure that the lifting device can smoothly lower the sector segment to the designated position and allow it to glide smoothly along the guide rail to the fixed device. Whether the sector segment can accurately reach the predetermined position depends directly on the accuracy of the guide rail.

[0003] Existing continuous casting machine guide rails typically employ a method of welding the guide rail plate to the external side of the vertical plate on one or both sides. This method results in insufficient welding stability, uneven stress distribution, and after prolonged use, the guide rails are susceptible to the effects of high-temperature moisture on-site, leading to significant changes in the welded structure and a risk of sagging. Summary of the Invention

[0004] In view of this, embodiments of the present invention provide a welding method for a continuous casting machine guide rail and a continuous casting machine guide rail, mainly used to solve the problems of existing guide rail plates being poorly welded, lacking precision after prolonged use, and being prone to falling off.

[0005] To achieve the above objectives, the present invention mainly provides the following technical solutions:

[0006] On one hand, the present invention provides a welding method for a continuous casting machine guide rail, comprising:

[0007] Prepare a guide rail plate, which includes a hollowed-out area;

[0008] Move the guide rail plate so that the cutout area corresponds to the end face of the upright plate;

[0009] The connection between the facade of the welded hollow area and the end face of the vertical plate is established through the hollow area.

[0010] The step of welding the connection between the vertical surface of the hollowed-out area and the end face of the vertical plate through the hollowed-out area includes:

[0011] Through the hollowed-out area, the four facades of the hollowed-out area are welded to the end faces of the upright plate in sequence.

[0012] The steps for welding the connection between the facade of the hollowed-out area and the end face of the vertical plate include: (The hollowed-out area has a beveled edge.)

[0013] The connection between the facade of the hollow area and the end face of the vertical plate is fixed by double-sided bevel welding, with the bevel angle being greater than or equal to 60° and less than or equal to 75°.

[0014] Before the step of connecting the welded hollow area's facade with the end face of the vertical plate, the method also includes:

[0015] Connecting plates are welded in segments along the length of the hollowed-out area, and the connecting plates are connected to the outer sides of the hollowed-out area in the width direction.

[0016] The steps for connecting the welded hollow area's facade to the end face of the vertical plate include:

[0017] The connection between the facade and the end face of the vertical plate of the segmented welded hollow area shall be such that the length of each segment welded shall be greater than or equal to 40cm and less than or equal to 70cm.

[0018] Following the step of connecting the welded hollow area's facade with the end face of the vertical plate, the method further includes:

[0019] Take the cover steel plate, embed it into the hollow area, and fix the cover steel plate.

[0020] The shape of the covering steel plate is adapted to the shape of the hollowed-out area.

[0021] The method also includes preparing an adjustment tool, which includes a support and an adjustment part. The support is used to fix the tool relative to the guide rail body, the adjustment part is connected to a replacement steel plate, and the adjustment part is movably connected to the support.

[0022] The steps of moving the guide rail plate to align the cut-out area with the end face of the upright plate include:

[0023] Move the guide rail plate to the height where it aligns with the upright plate, and use the adjustment tool to support the guide rail plate so that the cutout area corresponds to the end face of the upright plate;

[0024] Before the step of welding the connection between the vertical surface of the hollowed-out area and the end face of the vertical plate through the hollowed-out area, the method further includes:

[0025] The position of the guide plate is detected by measuring tools, and the guide plate is moved by the moving adjustment unit to adjust its position.

[0026] The support includes a horizontal support body and two vertical nuts, which are spaced apart on the horizontal support body. The horizontal support body also has two horizontal screw holes. There are four adjustment parts, which are bolts. The adjustment parts are used to be screwed onto the vertical nuts to abut against the side surface of the guide rail plate. The adjustment parts are also used to be screwed onto the horizontal screw holes to abut against the surface of the vertical plate opposite to the guide rail plate.

[0027] The step of adjusting the position of the guide rail plate by moving the guide rail plate through the adjustment unit includes:

[0028] The adjusting part is screwed on to move the guide rail plate through the action of the thread, thereby adjusting the position of the guide rail plate.

[0029] On the other hand, the present invention also provides a continuous casting machine guide rail, comprising:

[0030] The guide rail body includes two guide rail plates and a vertical plate. The two guide rail plates are spaced apart, and the vertical plate is located between the two guide rail plates.

[0031] The guide rail plate has a hollowed-out design, and the guide rail plate is welded and fixed to the end face of the vertical plate through the hollowed-out inner wall.

[0032] The continuous casting machine guide rail also includes:

[0033] A sprinkler system includes a sprinkler pipe and a sprinkler head connected to the sprinkler pipe. The sprinkler pipe is used to connect to a water supply device. The sprinkler system also includes a collection device.

[0034] The spray head is opposite to the guide rail plate of the guide rail body. The spraying device supplies water through the water supply component so that the spray head sprays water to the guide rail plate to clean the guide rail plate.

[0035] The collection device is located below the guide rail body. The collection device contains a filter screen. The collection device is used to collect sewage that slides down from the guide rail body, and the filter screen is used to filter the sewage.

[0036] This invention proposes a welding method for a continuous casting machine guide rail and the guide rail itself. The method primarily involves creating a hollowed-out area on the guide rail plate, which allows welding of the guide rail plate and the vertical plate from the center. This optimizes the structure, ensures functionality, and enables multi-sided welding stress, significantly enhancing the stability of the guide rail plate welding. This allows the guide rail to maintain excellent compressive strength even under high temperatures and equipment impacts, improving guide rail accuracy and lifespan while reducing costs.

[0043] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the following detailed description, in conjunction with the accompanying drawings and preferred embodiments, describes the specific implementation, structure, features, and effects of a welding method for a continuous casting machine guide rail proposed according to the present invention.

[0044] like Figure 1 As shown, this embodiment of the invention provides a welding method for a continuous casting machine guide rail, used to manufacture continuous casting machine guide rails. On the other hand, as... Figure 2-3 As shown, the present invention also provides a continuous casting machine guide rail, which is prepared by the aforementioned welding method of the continuous casting machine guide rail. In the following embodiments, the welding method is described in conjunction with the continuous casting machine guide rail. The continuous casting machine guide rail mentioned in the following embodiments can be used alone in the implementation of the continuous casting machine guide rail.

[0045] The continuous casting machine guide rail includes: a guide rail body (100), which includes two guide rail plates (110) and a vertical plate (120). The two guide rail plates (110) are spaced apart, and the vertical plate (120) is located between the two guide rail plates (110). The guide rail plates (110) are provided with perforations (111), and the guide rail plates (110) are welded and fixed to the end face of the vertical plate through the inner wall of the perforations (111).

[0046] The guide rail body (100) can have various shapes, such as a straight strip, i.e., the guide rail plate (110) is a flat plate structure; the guide rail body (100) can also be a curved structure, i.e., the guide rail plate (110) is an arc-shaped panel structure. The two guide rail plates (110) are parallel or equally spaced, and the vertical plate (120) is vertically connected between the two guide rail plates (110), thus forming a structure with an approximately I-shaped cross section in the extension direction.

[0047] The methods include:

[0048] S1. Prepare a guide plate (110), which includes a hollow area (111).

[0049] The cutout area (111) is an opening on the guide rail plate (110) that penetrates both sides of the guide rail plate (110). The cutout area (111) can be a long strip structure, and the two ends of the cutout area (111) in the length direction do not extend to the surrounding surface of the guide rail plate (110). In some embodiments, the length of the cutout area (111) is not less than two-thirds of the length of the guide rail plate (110), thereby ensuring that the welding connection area is large enough to ensure the connection strength of the guide rail plate (110). The width of the cutout area (111) is set according to the thickness of the end face of the upright plate (120), ensuring that the width of the cutout area (111) is less than the thickness of the end face of the upright plate (120), thereby making the cutout area (111) correspond to the inside of the end face of the upright plate (120), so that welding can be achieved through the edge of the cutout area (111) to the end face of the upright plate (120). The width of the hollow area (111) can be no less than one-third of the thickness of the vertical plate (120), thereby ensuring that the welding connection area is large enough to guarantee the connection strength of the guide plate (110) and to make way for the welding tools, making the welding process more convenient.

[0050] More specifically, the guide rail plate (110) is a high-strength, deformation-resistant steel plate with dimensions of 310cm×40cm×30mm. The central hollow area (111) of the guide rail plate (110) has dimensions of 280cm×9cm, while the thickness of the upright plate (120) can be 12cm, 15cm, etc.

[0051] S2. Move the guide rail plate (110) so that the hollow area (111) corresponds to the end face of the vertical plate (120);

[0052] The movable guide plate (110) can be moved by hoisting or manual handling by workers. After the guide plate (110) is moved to contact the upright plate (120), it can be continuously hoisted or fixed using additional fixing tools, such as clamping tools. Then, the position of the guide plate (110) is adjusted, and this adjustment method will be explained in more detail later. After the position of the guide plate (110) is adjusted, the cutout area (111) will correspond to the end face of the upright plate (120), and the surface of the guide plate (110) will connect with the end face of the upright plate (120).

[0053] S3. Weld the connection position between the vertical surface of the hollow area (111) and the end face of the vertical plate (120) through the hollow area (111).

[0054] Welding tools are inserted into the hollow area (111) to weld the contact position between the hollow area (111) and the end face of the vertical plate (120), thereby achieving welding from the inside of the guide plate (110). Compared with the traditional welding of the vertical plate (120) to the guide plate (110) on one or both sides, the welding strength of the guide plate (110) is higher.

[0055] This invention proposes a welding method for a continuous casting machine guide rail and the guide rail itself. The method primarily involves creating a hollowed-out area on the guide rail plate, which allows welding of the guide rail plate and the vertical plate from the center. This optimizes the structure while ensuring functionality, achieving four-sided welding and stress distribution. This significantly enhances the stability of the guide rail plate welding, enabling it to maintain excellent compressive strength even under high temperatures and equipment impacts, thereby improving guide rail accuracy, lifespan, and reducing costs.

[0056] In one embodiment, the step of welding the connection position between the vertical surface of the hollow area (111) and the end face of the vertical plate (120) through the hollow area (111) includes: welding the connection positions between the four vertical surfaces of the hollow area (111) and the end face of the vertical plate (120) in sequence through the hollow area (111).

[0057] The four-sided welding stress technology is innovatively adopted. Traditional welding methods mostly involve welding on one or two sides of the vertical plate (120), while the four-sided welding stress technology allows the guide plate (110) to be uniformly stressed in all directions, which greatly enhances its stability and compressive strength.

[0058] Furthermore, to accurately evaluate the improvement in the compressive strength of the guide plate (110), the following compressive strength formula is introduced: σ = F / A. Where σ is the compressive strength, F is the applied pressure, and A is the area under stress. For the guide plate of the prior art, after 20 tests under different pressure conditions, its average compressive strength was found to be σ1 = 200 MPa. For the anti-deformation guide plate (110) with four-sided welding of the hollow area (111) according to the embodiment of this application, 20 pressure tests were conducted under the same test environment and stress area, and its average compressive strength was found to be σ2 = 270 MPa. That is, the compressive strength F2 of the guide plate (110) according to the embodiment of this application is increased by 35% compared to the compressive strength F1 of the guide plate of the prior art. From the test results of actual application scenarios, in a certain actual production environment, under harsh conditions of high temperature (1200-1500℃), high humidity (80%-95% relative humidity) of the cast billet and frequent impacts from equipment (5-8 impacts per minute, with impact force between 5-10kN), the guide rail plate of the prior art showed obvious deformation and local damage after 1440 hours of continuous operation, and the compressive strength dropped to 150MPa. The anti-deformation guide rail plate (110) with the hollow area (111) welded on all four sides according to the embodiment of this application, still maintained good structural integrity after 1440 hours of the same harsh working conditions test, and the compressive strength only dropped to 250MPa. This fully demonstrates that the improved guide rail plate (110) has significantly enhanced compressive performance, can better cope with the high temperature and equipment impact force at the continuous casting machine site, and greatly improves the service life and reliability of the guide rail.

[0059] In one embodiment, a bevel is provided on the vertical surface of the hollow area (111), and the step of welding the connection position between the vertical surface of the hollow area (111) and the end face of the vertical plate (120) includes: the connection position between the vertical surface of the hollow area (111) and the end face of the vertical plate (120) is fixed by double-sided bevel welding.

[0060] In terms of welding fixation, the traditional single-sided or simple bevel welding is abandoned. Instead, a double-sided bevel welding technique is innovatively used to fix the guide rail plate (110) on both sides of the hollow area (111). This unique welding method greatly increases the contact area and interlocking force of the weld. After extensive experimental verification, the tensile strength of the weld is increased by 30% compared with the traditional welding method, ensuring that the weld is firm and reliable, and effectively avoiding the problem of cracking at the weld due to vibration, uneven stress and other factors during the operation of the continuous casting machine when changing the lower sector section.

[0061] The beveling angle on both sides should be greater than or equal to 60° and less than or equal to 75°. This avoids the problem of high residual stress generated during cooling and shrinkage of welds with large beveling angles, which could induce cracks or reduce the fatigue strength of the structure. At the same time, it avoids the risk of insufficient penetration or poor fusion at the root, which could restrict the oscillation space of the welding torch or electrode and lead to hidden defects.

[0062] To further control welding deformation, one embodiment employs an innovative segmented welding connection method. The step of welding the connection position between the vertical surface of the hollow area (111) and the end face of the vertical plate (120) includes: segmentally welding the connection position between the vertical surface of the hollow area (111) and the end face of the vertical plate (120).

[0063] Through numerous comparative experiments with welds of varying lengths, a weld length greater than or equal to 40cm and less than or equal to 70cm ensures better control of welding deformation. If the weld length is too short, it cannot effectively fix the guide rail plate (110), and in subsequent simulated operation tests, the probability of weld cracking is as high as 50%. When the weld length is between 70-100cm, the heat generated during welding is too concentrated, easily leading to significant deformation of the guide rail plate (110), with a maximum deformation of up to 3mm. The weld length can be 50cm.

[0064] To quantify the effect of segmented welding on preventing deformation, the formula for thermal deformation, ΔL = aLΔT, is introduced, where ΔL is the thermal deformation, a is the coefficient of thermal expansion of the material, L is the weld length, and ΔL is the temperature change during welding. Twenty thermal deformation tests were conducted on both the original continuous welding process and the innovative segmented welding process. The riveted and welded parts were made of the same material as the continuous casting machine guide rail, with a coefficient of thermal expansion of a = 1.2 × 10⁻⁶. -5 / ℃. The original continuous welding length L = 150 cm. During the welding process, the temperature change ΔT1 = 800℃. According to the formula for thermal deformation, the thermal deformation ΔL1 generated by the original continuous welding is 1.2 × 10⁻⁶. -5 ×150×800=1.44cm. After segment welding using this embodiment, the length of each weld segment L2=50cm, and due to the rapid heat dissipation of segment welding, the temperature change at the segment welding site ΔT2=480℃, as monitored by an imaging device and measured in real time by a temperature sensor, ΔT2 is reduced by 40% compared to the original continuous welding, and the thermal deformation ΔL2 generated by segment welding is 1.2×10 -5 ×50×480=0.288cm. The comparison shows that the thermal deformation of the segment weld is significantly reduced compared to the original continuous weld, with a reduction of approximately 80%. This effectively ensures the accuracy of the guide rail and significantly improves the welding quality and overall performance of the continuous casting machine guide rail.

[0065] In one embodiment, before the step of connecting the vertical surface of the welded hollow area (111) with the end face of the vertical plate (120), the method further includes: welding a connecting plate (130) in segments along the length direction of the hollow area (111), the connecting plate (130) being connected to the outer sides of both sides of the hollow area (111) in the width direction.

[0066] like Figure 4 As shown, the connecting plate (130) is a temporary fixing plate, and a connecting plate (130) is installed at each welding point for fixation to prevent large-area deformation from affecting accuracy. When using the aforementioned segmented welding connection method, the connecting plate (130) is set corresponding to the position of each weld segment. The fixing plate spans the hollow area (111), and both ends are connected to the outer surface of the hollow area (111). The connection method can be spot welding. Through the fixing and protection function of the connecting plate (130), it can fix the structure on both sides of the hollow area (111) and reduce local deformation during the welding process.

[0067] In one embodiment, after the step of connecting the vertical surface of the welded hollow area (111) with the end face of the vertical plate (120), the method further includes: taking a cover steel plate and embedding it into the hollow area (111), and fixing the cover steel plate; the shape of the cover steel plate is adapted to the hollow area (111).

[0068] The cover steel plate is a strip-shaped structure that can be embedded in the hollow area (111), such as a steel plate slightly smaller than 280cm × 9cm × 30mm. After welding, the cover steel plate fills the hollow area (111), thereby shielding the weld section and reducing corrosion of the weld section by harsh environmental factors such as high humidity, thus further ensuring the stability of the weld. At the same time, the contact between the cover steel plate and the side wall of the hollow area (111) also provides support for the hollow area (111), reducing the risk of deformation of the hollow area (111). The cover steel plate can be fixed in the hollow area (111) by welding.

[0069] In one implementation, such as Figure 5 As shown, the continuous casting machine guide rail also includes a spraying device (300), which includes a spray pipe (310) and a spray head (320) connected to the spray pipe (310). The spray pipe (310) is used to connect to a water supply component. The spraying device (300) also includes a collection device. The spray head (320) is opposite to the guide plate (110) of the guide rail body (100). The spraying device (300) supplies water through the water supply component so that the spray head (320) sprays water towards the guide plate (110) to clean the guide plate (110). The collection device is located below the guide rail body (100). The collection device is equipped with a filter screen and is used to collect wastewater that slides down from the guide rail body (100). The filter screen is used to filter the wastewater.

[0070] More specifically, double rows of 304 stainless steel spray pipes (310) can be arranged parallel to the longitudinal direction of the guide rail plate (110) of the guide rail body (100), with a pipe diameter of Φ10mm×3100mm, to more efficiently cover the guide rail spray area. The spray pipes (310) can be installed in sections, making installation and maintenance convenient. The length of each section of the spray pipe (310) can be between 100cm and 180cm, such as 155cm. Adjacent spray pipes (310) are connected by quick-release flanges. The spray heads (320) are connected to the spray pipes (310), and can be set at intervals of 15cm±0.5mm to ensure comprehensive spraying. The angle and position of the spray heads (320) can be flexibly adjusted according to the site conditions and water pressure, and this application does not limit them.

[0071] In one specific implementation, the height difference between the outlet of the spray head (320) and the guide rail plate (110) in the longitudinal direction is 3cm ± 0.5cm, and the horizontal distance between the outlet and the guide rail plate (110) is 8cm, achieving full coverage of the guide rail area without dead angles. The spray head (320) is angle-adjustable, such as having an adjustable spray angle of 45°. During installation, the angle of the spray head (320) can be set to an angle of 30° ± 2° with the longitudinal direction, which can be flexibly adjusted according to different actual needs to achieve the best spraying effect. The nozzle diameter of the outlet of the spray head (320) is 2mm, and when the single-hole flow rate is 0.25L / min, the water flow velocity can reach 8m / s. This combination of controlled system parameters ensures that the water flow has sufficient impact force while guaranteeing coverage.

[0072] The collection device may further include a collection tank and a converging device. The collection tank is located below the guide rail body (100), and the converging device is located at the end of the collection device. The bottom of the collection tank slopes downward toward the converging device. The converging device is equipped with a filter screen with a sufficient area, such as 400cm × 200cm × 150mm. The collection tank is used to collect wastewater that slides down from the guide rail body (100) and flows to the converging device. The filter screen is used to filter the wastewater, and the converging device can centrally treat and recycle the filtered wastewater. The dirt and iron oxide scale generated during each flush can be discharged from a high level to a low level for collection, which helps to protect the production environment and improve the collection and treatment effect of the spray water.

[0073] In one embodiment, the method further includes preparing an adjustment tool (200), the adjustment tool including a support part (210) and an adjustment part (220), the support part (210) being fixed relative to the guide rail body (100), the adjustment part (220) being connected to a replacement steel plate, and the adjustment part (220) being movably connected to the support part (210). The step of moving the guide rail plate (110) to make the hollow area (111) correspond to the end face of the upright plate (120) includes: moving the guide rail plate (110) to a height that aligns with the upright plate (120), and supporting the guide rail plate (110) with the adjustment tool (200) so that the hollow area (111) corresponds to the end face of the upright plate (120). Before the step of welding the connection position of the vertical surface of the hollow area (111) and the end face of the vertical plate (120) through the hollow area (111), the method further includes: detecting the position of the guide plate (110) by measuring tool, and pushing the guide plate (110) to move by moving adjustment part (220) to adjust the position of the guide plate (110).

[0074] The support part (210) is fixedly installed. By moving the adjustment part (220) relative to the support part (210), the guide rail plate (110) is pushed to move, thereby adjusting the relative position with the upright plate (120). The guide rail plate (110) can be aligned as needed to ensure accurate positioning. The measuring tools can be position measuring tools such as a level, or gap measuring tools such as a top ruler.

[0075] In a more specific implementation, such as Figure 6 As shown, the support part (210) includes a horizontal support body and two vertical nuts, spaced apart on the horizontal support body. The horizontal support body also has two horizontal screw holes. There are four adjusting parts (220), each a bolt. The adjusting parts (220) are screwed onto the vertical nuts to abut against the side surface of the guide rail plate (110), and onto the horizontal screw holes to abut against the surface of the opposite vertical plate (120) of the guide rail plate (110). The step of moving the guide rail plate (110) by moving the adjusting parts (220) to adjust its position includes: screwing the adjusting parts (220) so that the adjusting parts (220) drive the guide rail plate (110) to move through the thread action, thereby adjusting the position of the guide rail plate (110).

[0076] The adjustment tool (200) can also be called a figure-7 plate, and the adjustment part (220) can be an M24 bolt. Multiple adjustment tools (200) are spaced along the length of the guide rail body (100). For example, in an embodiment where the total length of the guide rail body (100) is 12 meters, an adjustment point can be set every 2 meters along the length direction, and an adjustment tool (200) can be set for each adjustment point. That is, the entire guide rail body (100) is equipped with 6 adjustment tools (200), and each adjustment tool (200) contains 4 M24 adjusting bolts. The adjustment tool (200) is made of high-strength, high-toughness alloy steel to ensure that it will not deform during frequent adjustment operations and to guarantee the stability of adjustment accuracy. The adjustment tool (200) is precisely machined with threaded holes that match the M24 bolts. The positions of these threaded holes are precisely calculated and correspond to the six pre-set adjustment points on the guide rail. A stable connection between the figure-7 plate and the guide rail is achieved by passing the M24 bolt through the horizontal screw hole and the vertical nut of the figure-7 plate and tightening it on the guide rail adjustment point of the guide rail plate (110).

[0077] Adjustment Method: Initially install the prepared L7 plate onto the six adjustment points of the guide rail using M24 bolts. Do not fully tighten the bolts at this stage; allow for some leeway for subsequent adjustments. During installation, use a level and right-angle ruler to calibrate the horizontal support angle of the L7 plate, ensuring it is tightly fitted to the guide rail and level. Adjust the guide rail by rotating the M24 bolts at the corresponding positions. For example, using... Figure 6 Taking the direction shown as an example, if the guide rail needs to be adjusted to the left, the M24 bolt on the right adjustment point can be rotated clockwise, so that the figure-eight plate exerts a leftward pushing force on the guide rail plate (110), pushing the guide rail plate (110) to move slowly; if the guide rail plate (110) needs to be adjusted upward, the bolt on the lower adjustment point is adjusted. During the adjustment process, the amplitude of each bolt rotation should be small, usually controlled within a very small angle range, and the position change of the guide rail plate (110) should be monitored in real time using measuring tools to ensure adjustment accuracy. Due to the high-precision design of this tool, the adjustment accuracy can reach within 0.10mm, which can meet the extremely high precision requirements of the continuous casting machine guide rail. Compared with traditional adjustment tools, this tool innovatively realizes a four-way adjustment function. This allows the direction of the force exerted by the figure-eight plate on the guide rail plate (110) to be flexibly changed by rotating the M24 bolts at different positions during the adjustment process, thereby realizing precise fine-tuning of the guide rail plate (110) in four directions, meeting the complex requirements of high-precision installation and real-time adjustment of the continuous casting machine guide rail within 0.10mm.

[0078] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
