Description

Technical Field

[0001] This utility model belongs to the technical field of smelting equipment, and in particular relates to a crucible cutting, clamping and transfer device for slag resistance experiments. Background Technology

[0002] Metallurgical crucibles are deep cup-shaped refractory containers used for high-temperature melting of metals or alloys. Their core function is to provide a sealed environment that isolates the material from the outside world and resists corrosion during heating, melting, and chemical reactions. They are usually made of materials with high refractoriness and thermal stability, such as graphite, clay, and corundum, and can withstand extreme temperatures far above the melting point of metals (such as above 1500℃) as well as chemical erosion from slag and molten metal. They are widely used in laboratory research, small-batch refining, or ingot casting processes for special steels, non-ferrous metals, rare earth materials, and precious metals.

[0003] The crucible slag resistance test is a classic static test method for evaluating the corrosion resistance of refractory materials. Its core is to load a metallurgical slag of a specific composition into a crucible made of the refractory material to be tested, heat it in a high-temperature furnace to a temperature much higher than the melting point of the slag (usually 1500-1650℃), and hold it at that temperature for a long time. By analyzing the erosion depth, penetration area, and microstructure changes of the crucible profile after cooling, the ability of different materials to resist chemical erosion and physical penetration by slag can be qualitatively or semi-quantitatively compared. This provides key experimental basis for the screening and optimization of lining materials for industrial kilns.

[0004] In the prior art, such as the crucible cutting, clamping and transfer device for slag resistance testing disclosed in Chinese Patent (CN221642496U), which belongs to the field of metallurgical ironmaking technology, a car plate and a wheel assembly set on the bottom surface of the car plate are included. Two sets of crucible clamping mechanisms are symmetrically arranged on the upper surface of the car plate and spaced apart. Each set of crucible clamping mechanisms includes a fixed clamping block on the left and a movable clamping block on the right. The movable clamping block is slidably connected to the car plate. Crucible clamping grooves are provided on the fixed clamping block and the movable clamping block on the adjacent side of the two sets of crucible clamping mechanisms.

[0005] This method has the following drawbacks: First, when cutting crucibles using this device, the front end of the cutting blade needs to be inserted into the protective cover of the device to prevent dust from spreading. However, the cutting blade is usually connected to a power structure on the side, preventing it from fully extending into the protective cover. Furthermore, the field of vision is limited once the cutting device is inside the protective cover, and the narrow space of the protective cover opening makes it difficult to move the cutting blade up and down. Second, during the cutting operation, dust generated from cutting the crucible spreads into the interior of the protective cover. The components used to clamp and fix the crucible are also located inside the protective cover, resulting in a large amount of dust accumulating in the internal mechanisms of the protective cover, making cleaning difficult and reducing the lifespan of the device. Third, this device can only process one crucible at a time. When processing multiple sets of crucible experimental samples from the same batch, the processed crucibles need to be removed, fixed, transported, and cut separately multiple times, and then the samples need to be removed again for further processing. This method results in low crucible processing efficiency.

[0006] Therefore, this utility model provides a crucible cutting, clamping and transfer device for slag resistance experiments. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model discloses a crucible cutting, clamping and transfer device for slag resistance experiments. It can clamp and fix each crucible in the vertical direction for cutting, which improves the efficiency of cutting with the device. Moreover, during cutting, only the position of the clamping base needs to be adjusted back and forth, and the cutting blade needs to be moved up and down to perform the cutting action, which reduces the cutting difficulty. The structure of the clamping base is simple and reliable. After the cutting operation is completed, it can be rinsed with clean water, which is simple and efficient.

[0008] To achieve the above technical effects, this utility model provides a crucible cutting, clamping, and transporting device for slag resistance experiments, including a clamping base, casters, and a dust cover. The casters with a self-locking function are located below the clamping base, and the dust cover is located above the clamping base. The clamping base also includes a push rod mechanism, a base body, and a latch. The push rod mechanism is located on the rear side of the base body, which is configured as two interlocking pieces. The rear end of the base body is connected by a hinge, and the latch is located on the front side of the base body. The dust cover is divided into left and right parts, which are respectively installed on the base body, and an opening is provided on the top of the dust cover.

[0009] Preferably, the push rod mechanism further includes connecting rod a, connecting rod b, and mounting base. The mounting base is respectively located on the rear side of the base body. Connecting rod a is inserted into the mounting base and fixed by welding. Connecting rod b is welded and fixed to the upper end of connecting rod a. The left and right connecting rods b are connected by hinges.

[0010] Preferably, the base body further includes a crucible placement platform, a docking groove, and clamping blocks. The docking groove is located at the center of the base body, the crucible placement platform is located above the docking groove, and the clamping blocks are located inside the crucible placement platform.

[0011] Preferably, the crucible placement platform further includes a support platform and a clamp, with the clamp located above the support platform and configured as an outwardly expanding conical structure.

[0012] Preferably, the right side of the support platform of the crucible placement stage located on the left is provided with an extended support base, the length of which is less than the distance from the left end of the docking groove to the center line of the base body.

[0013] Preferably, the crucible placement platforms are respectively eccentrically arranged on the center line of the base body.

[0014] Preferably, the dust cover is eccentrically positioned on the center line of the base body.

[0015] Preferably, the dust cover has a dust baffle plate at the top of its interior, with the dust baffle plates arranged on both sides of the opening.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This device features interlocking clamping bases, with the cutting blade opening positioned above the dust cover. This allows for vertical clamping and fixing of various crucibles during cutting, improving efficiency. Furthermore, during cutting, simply moving the clamping bases back and forth and the cutting blade up and down eliminates concerns about the dust cover restricting visibility or hindering blade movement, thus reducing cutting difficulty. The clamping bases have a simple and reliable structure, preventing dust accumulation and extending the device's lifespan. After cutting, cleaning with water is all that's needed, making cleaning simple and efficient. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Example 1

[0019] like Figures 1 to 4 As shown The prior art in this embodiment has the following problems: The inventors have discovered the following defects in the prior art: 1. The cutting blade cannot be fully inserted into the protective cover for cutting, and the cutting device's field of vision is limited after being inserted into the protective cover, making it difficult to move the cutting blade up and down. Second, during use, a large amount of dust will accumulate in the mechanism inside the protective cover, making cleaning difficult and reducing the service life of the device; Third, the device can only process one crucible at a time, resulting in low processing efficiency. Therefore, the inventor provides a crucible cutting, clamping, and transporting device for slag resistance experiments, including a clamping base, casters 1, and a dust cover 2. The casters 1 with a self-locking function are located below the clamping base, and the dust cover 2 is located above the clamping base. The clamping base also includes a push rod mechanism 3, a base body 4, and a latch 5. The push rod mechanism 3 is located on the rear side of the base body 4, and the base body 4 is configured as two interlocking structures. The rear end of the base body 4 is connected by a hinge, and the latch 5 is located on the front side of the base body 4. The dust cover 2 is divided into left and right parts and is respectively located on the base body 4. An opening 6 is provided on the top of the dust cover 2.

[0020] Using the above scheme, after the test crucibles are heated in the test furnace, the operator uses crucible clamps to pick up the crucibles and place them onto the open clamping base. Then, the base body 4 is closed by the push rod mechanism 3 and fixed by the buckle 5, so that the crucibles are clamped on the base body 4. After the crucibles are placed, the self-locking of the universal wheel 1 is released, and the crucibles on the device are transferred to the bottom of the cutting machine by the push rod mechanism 3. After aligning the opening 6 above the dust cover 2 with the cutting blade, the universal wheel 1 is locked, and then the cutting is started. The machine presses down the cutting blade to cut the crucible on the clamping base below. After cutting the middle crucible, the cutting blade is lifted, the universal wheel 1 is released, and the clamping base is moved forward and backward so that the cutting blade can cut other crucibles when it is pressed down. After cutting all the crucibles on the clamping base in this way, the cutting machine is turned off. During the cutting process, the dust raised by the cutting blade is confined inside the dust cover 2. The clamping base is moved out and transferred to the observation and test location, completing the cutting and transfer of the crucibles. Example 2

[0021] like Figures 1 to 4 As shown Furthermore, the push rod mechanism 3 also includes a connecting rod a7, a connecting rod b8, and a mounting base 9. The mounting base 9 is respectively located on the rear side of the base body 4. The connecting rod a7 is inserted into the mounting base 9 and fixed by welding. The connecting rod b8 is welded and fixed to the upper end of the connecting rod a7. The connecting rods b8 on the left and right sides are connected by hinges. When the base body 4 holding the base is closed, the connecting rods b8 on the rear side of the two base bodies 4 form an angle of 180 degrees. After the buckle 5 at the front end of the base body 4 is released, the connecting rods a7 on both sides are pulled to open the base body 4 outward. At the same time, the angle between the connecting rods b8 decreases, and the hinge connection between the connecting rods b8 and the hinge connection between the base bodies 4 are opened, so that the tester can put the crucible into the base body 4 or take out the cut crucible. The connecting rods a7, connecting rods b8 and mounting base 9 can all be made by splicing and welding discarded pipes from the production workshop. Example 3

[0022] like Figures 1 to 4 As shown Furthermore, the base body 4 also includes a crucible placement platform, a docking groove 10, and a clamping block 11. The docking groove 10 is located at the center of the base body 4, the crucible placement platform is located above the docking groove 10, and the clamping block 11 is located inside the crucible placement platform. Furthermore, the crucible placement platform also includes a support platform 12 and a clamp 13. The clamp 13 is located above the support platform 12 and is configured as an outwardly expanding conical structure. Furthermore, an extended support base 14 is provided on the right side of the support platform 12 of the crucible placement platform located on the left side. The length of the support base 14 is less than the distance from the left end of the docking groove 10 to the center line of the base body 4. When the base body 4 is separated, the experimenter places the crucible to be cut on the support platform 12 of the crucible placement platform on the left. The support platform 12 on the left is provided with an extended support seat 14, which allows the crucible to be temporarily placed on the crucible placement platform. After the crucible is placed, the base body 4 is closed by the push rod mechanism 3. The right end of the left base body 4 is close to the right base body 4. The two base bodies 4 are joined together below the crucible to form a docking groove 10. The crucible is located on the support platform 12 above the docking groove 10. The support platforms 12 on the two base bodies 4 are joined together to clamp and fix the crucible from the left and right sides. The clamping block 11, made of high temperature resistant flexible material, can form a buffer between the outer wall of the crucible and the clamping seat 13, increasing the contact surface between the clamping seat 13 and the side wall of the crucible, so that the base body 4 can clamp the crucible tightly. During cutting, the cutting blade enters through the opening 6 on the dust cover 2 and cuts the crucible from top to bottom. The support platform 12 and the docking groove 10 lift the crucible and suspend it in the air to prevent the cutting blade from contacting the base body 4 during cutting. At the same time, the length of the support seat 14 used to provide support is less than the distance from the left end of the docking groove 10 to the center line of the base body 4, so that the right end of the support seat 14 is located to the left of the center line of the base body 4 cut by the cutting blade, providing support for the crucible while preventing the cutting blade from cutting into the support seat 14 when cutting downwards. This method allows for vertical clamping and cutting of each crucible, improving the efficiency of cutting with the device. Furthermore, during cutting, the position of the clamping base can be adjusted by moving it back and forth, and the cutting blade can be moved up and down to perform the cutting action. There is no need to worry about the dust cover 2 causing limited visibility or difficulty in moving the cutting blade, thus reducing the difficulty of cutting. Example 4

[0023] Furthermore, the crucible placement platforms are respectively eccentrically set on the center line of the base body 4 (not shown in the figure); Furthermore, the dust cover 2 is eccentrically positioned on the center line of the base body 4 (not shown in the figure). The crucible placement platform is eccentrically positioned on the base body 4, such that the area of ​​the support platform 12 on the left side of the base body 4 is larger than the area of ​​the support platform 12 on the right side. This allows the crucible to be securely placed on the crucible placement platform on the left side when the base body 4 is opened to place the crucible. The dust cover 2 is eccentrically positioned on the base body 4, with its center line coinciding with the center line of the crucible placement platform. This facilitates the protection of the crucible while ensuring that the cutting blade can be cut from the center of the crucible during cutting. The eccentric dimension should preferably be set between 1 cm and 2 cm. Example 5

[0024] like Figures 1 to 4 As shown Furthermore, a dust baffle 15 is provided at the top of the interior of the dust cover 2, and the dust baffles 15 are respectively arranged on both sides of the opening 6; During the cutting process, the dust generated by the cutting blade is shot to the top of the dust cover 2. The dust baffle 15 can increase the contact area between the dust cover 2 and the dust, so that the dust cover 2 can isolate and block more dust. The dust baffle 15 can be cut and welded onto the dust cover 2 using angle steel. With this device, the interior of the dust cover 2 only has a simple support platform 12 and a clamp 13. There is no need to worry about dust accumulating on the device and reducing its service life. After the cutting operation is completed, it can be rinsed with clean water, making the cleaning method simple and efficient.

[0025] In summary, this device features interlocking clamping bases, with the cutting blade opening 6 positioned above the dust cover 2. This allows for vertical clamping and fixing of various crucibles during cutting, improving efficiency. Furthermore, during cutting, simply moving the clamping bases back and forth and the cutting blade up and down eliminates concerns about the dust cover 2 restricting visibility or hindering blade movement, thus reducing cutting difficulty. The clamping bases have a simple and reliable structure, preventing dust accumulation and extending the device's lifespan. After cutting, cleaning with water is sufficient for rinsing, making cleaning simple and efficient.

[0026] The working principle of this utility model: After the crucibles used in the experiment are heated in the experimental furnace, the experimenter uses crucible clamps to clamp the crucibles onto the open clamping bases. In the scheme of embodiment 3, an extended support base 14 is provided on the left support platform 12, which allows the crucible to be temporarily placed on the crucible placement platform. After the crucible is placed, the base body 4 is closed by the push rod mechanism 3. The right end of the left base body 4 is close to the right base body 4. The two base bodies 4 are joined together below the crucible to form a docking groove 10. The crucible is located on the support platform 12 above the docking groove 10. The support platforms 12 on the two base bodies 4 are joined together to clamp and fix the crucible from the left and right sides. The clamping block 11 made of high temperature resistant flexible material can form a buffer between the outer wall of the crucible and the clamping base 13, increasing the contact surface so that the base body 4 can clamp the crucible. The base body 4 is fixed by the buckle 5 so that the crucible is clamped on the base body 4. In the scheme of embodiment 4, the crucible placement platform is eccentrically set on the base body 4, so that the area of ​​the support platform 12 on the left side of the base body 4 is larger than the area of ​​the support platform 12 on the right side. In this way, when the base body 4 is opened to place the crucible, the crucible can be placed securely on the crucible placement platform on the left side. The dust cover 2 is eccentrically set on the base body 4, and the center line of the dust cover 2 coincides with the center line of the crucible placement platform. This facilitates the protection of the crucible while ensuring that the cutting blade can be cut from the center of the crucible during cutting. The eccentric size should preferably be set between 1 cm and 2 cm. After the crucible is placed, release the self-locking of the universal wheel 1, and transfer the crucible on the device to the bottom of the cutting machine through the push rod mechanism 3. Align the opening 6 above the dust cover 2 with the cutting blade, lock the universal wheel 1, and then start the cutting machine to press down the cutting blade to cut the crucible on the clamping base below. During cutting, the cutting blade enters through the opening 6 on the dust cover 2 and cuts the crucible from top to bottom. The support platform 12 and the docking groove 10 lift the crucible and suspend it in the air to prevent the cutting blade from contacting the base body 4 during cutting. At the same time, the length of the support seat 14 used to provide support is less than the distance from the left end of the docking groove 10 to the center line of the base body 4, so that the right end of the support seat 14 is located to the left of the center line of the base body 4 cut by the cutting blade, providing support for the crucible while preventing the cutting blade from cutting into the support seat 14 when cutting downwards. This method allows for vertical clamping and cutting of various crucibles, improving the efficiency of cutting with the device. Furthermore, during cutting, it is only necessary to move the clamping base back and forth to adjust its position and the cutting blade up and down to perform the cutting action. There is no need to worry about the dust cover 2 causing limited visibility or difficulty in moving the cutting blade, thus reducing the difficulty of cutting. After cutting the middle crucible, lift the cutting blade, release the lock of the universal wheel 1, and move the clamping base forward and backward so that the cutting blade can cut other crucibles when it presses down. After cutting all the crucibles on the clamping base in this way, turn off the cutting machine. During the cutting process, the dust generated by the cutting blade is shot to the top of the dust cover 2. The dust baffle 15 can increase the contact area between the dust cover 2 and the dust, so that the dust cover 2 can isolate and block more dust. The dust baffle 15 can be cut and welded onto the dust cover 2 using angle steel. With this device, the interior of the dust cover 2 only has a simple support platform 12 and a clamp 13. There is no need to worry about dust accumulating on the device and reducing its service life. After the cutting operation is completed, it can be rinsed with clean water, making the cleaning method simple and efficient. After cutting, the clamping base is moved to the observation and testing location, completing the cutting and transfer of the crucible.
