Technical Field

[0001] This utility model relates to the field of ferromanganese alloy casting technology, specifically to a mounting and fixing device for a ferromanganese alloy casting anti-splash baffle. Background Technology

[0002] Ferromanganese alloy is an iron alloy smelted from manganese ore. Its main components are manganese and iron. It is used in casting, power equipment manufacturing, new energy vehicles, aerospace and other fields, and can improve the hardness, wear resistance and oxidation resistance of steel.

[0003] In the casting of ferromanganese alloys, severe splashing often occurs due to the high temperature, high fluidity, and impact force of the molten alloy. This not only threatens the safety of on-site operators, increasing the risk of burns and other accidents, but also corrodes surrounding equipment, shortening its service life and increasing production costs.

[0004] In current ferromanganese alloy casting operations, the mainstream method to reduce the impact of splashing is to install baffles on the furnace body used for casting ferromanganese alloy. The baffles can prevent the alloy liquid from splashing out of the furnace body. However, most of the current baffles are fixed installations, which are inconvenient to disassemble and replace, thus affecting production efficiency.

[0005] To address this issue, this utility model provides a mounting and fixing device for a manganese-iron alloy cast anti-splash baffle, thereby solving the aforementioned problems. Summary of the Invention

[0017] Compared with existing technologies, the beneficial effects of this utility model are as follows: The present invention relates to a mounting and fixing device for a manganese-iron alloy casting anti-splash baffle. This device comprises a first mounting component mounted on the furnace body and second mounting bodies on both sides of the baffle.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4As shown, the mounting and fixing device for the manganese-iron alloy cast anti-splash baffle provided by this utility model includes a first mounting body 2 and a second mounting body 3. The first mounting body 2 is disposed on the furnace body and has a through mounting hole 201. A first fixing groove 202 is provided below the mounting hole 201. An expansion member 4 is movably connected in the first fixing groove 202. In this embodiment, the expansion member 4 is similar in shape and size to the first fixing groove 202. The expansion member 4 is directly placed into the first fixing groove 202, and the top of the expansion member 4 is flush with the opening of the first fixing groove 202 at room temperature. The second mounting body 3 is disposed on one side of the baffle 1 and can be inserted into the mounting hole 201 and rotate within the mounting hole 201. A second fixing groove 301 is provided on one side of the second mounting body 3. When the second mounting body 3 is inserted into the mounting hole 201, the second fixing groove 301 can be aligned with the first fixing groove 202. The expansion member 4 can expand under high temperature, so that the expansion member 4 enters the second fixing groove 301 to prevent the second mounting body 3 from rotating.

[0022] During installation, the first mounting body 2 is installed above the furnace body and can be fixedly connected by bolts or other means. The expansion member 4 is placed into the first fixing groove 202, and then the second mounting body 3 is inserted into the mounting hole 201 and parallel to the edge of the furnace body. At this time, the first fixing groove 202 and the second fixing groove 301 are aligned. During the casting operation, the temperature of the baffle 1 will rise, causing the expansion member 4 to expand. A part of the expanded expansion member 4 enters the first fixing groove 202, so that the first fixing groove 202 is fixedly connected to the second fixing groove 301 through the expansion member 4, thereby fixing the rotation of the baffle 1 and keeping the baffle 1 in a fixed state during the casting operation to effectively resist the impact of alloy liquid splashing. In the non-casting operation state, the expansion member 4 contracts until it is completely inside the first fixing groove 202. Since the second mounting body 3 is directly inserted into the mounting hole 201, the second mounting body 3 can rotate freely in the mounting hole 201, thereby allowing the baffle 1 to rotate, which facilitates non-casting operations such as material removal. At the same time, in the non-casting operation state, the second mounting body 3 can also be removed from the mounting hole 201, which facilitates the replacement of the baffle 1.

[0023] Furthermore, the expansion component 4 is made of alumina ceramic, and its height is greater than 100mm. Alumina ceramic can withstand high temperatures of 2000 degrees Celsius and can operate stably for extended periods, similar to the casting temperature of ferromanganese alloys at 1600 degrees Celsius. Based on the characteristics of thermal expansion, the coefficient of linear expansion of alumina in the range of 0~1400℃ is... Taking the lowest value as an example, when the height of the expansion component 4 is 100mm and the temperature change is 1400℃, the expansion amount is... .

[0024] If the expanded component uses higher purity (e.g., 99.7%) or the sintering process is optimized, the coefficient of thermal expansion can be further increased to [missing value]. The corresponding expansion amount is 1.37 mm. As can be seen above, when the top of the expansion member 4 is flush with the opening of the first fixing groove 202 at room temperature, during the casting operation, the expansion amount of the expansion member 4 in the height direction is greater than 1 mm, causing the top of the expansion member 4 to enter the first fixing groove 202, so that the first fixing groove 202 is fixedly connected to the second fixing groove 301 through the expansion member 4, thereby fixing the rotation of the baffle 1. Secondly, the elastic modulus of alumina is 380 GPa, its bending strength is between 330-380 MPa, its compressive strength exceeds 2000 MPa, and its hardness reaches Mohs 9, second only to diamond. This high rigidity characteristic allows it to withstand high mechanical loads at high temperatures, reducing the possibility that the expansion member 4 will plastically deform and lose its fixation to the baffle 1 due to the long-term force exerted by the baffle 1 on the expansion member 4. In this embodiment, a release groove 5 is provided below the first fixing groove 202. The release groove 5 is connected to the outer wall of the first mounting body 2. A release member 6 is slidably connected in the release groove 5. The height of the release member 6 is the same as the height of the release groove 5. The release member 6 can lift the expansion member 4 to the top of the release member 6. A handle 7 is provided at one end of the release member 6 near the outer wall of the first mounting body 2. When the expansion member 4 is above the release member 6, the top of the expansion member 4 is flush with the opening of the first fixing groove 202.

[0025] When the ferromanganese alloy casting is completed but the working temperature has not yet dropped and the casting needs to be removed urgently, the baffle 1 is still in a fixed state because the release part 6 has not yet fully contracted. At this time, the release part 6 is pulled out, and the expansion part 4 falls from the first fixed groove 202 to the release groove 5, so that the expansion part 4 is released from the constraint of the second fixed groove 301 in advance, allowing the baffle 1 to rotate. This is used to deal with the situation where the baffle 1 needs to be lowered in an emergency, and can also improve production efficiency in environments with slow cooling or in situations where continuous production is required.

[0026] Furthermore, the lower part of the expansion member 4 adopts a rounded transition, and the end of the release member 6 away from the handle 7 adopts a rounded transition, so that when the release member 6 moves towards the first fixing groove 202, the expansion member 4 is forced to move upward.

[0027] When the release member 6 is removed, the expansion member 4 falls from the first fixing groove 202 into the release groove 5, thereby releasing the constraint on the second fixing groove 301 in advance. This setting can restore the above state to the normal state. In use, the release member 6 is pushed into the release groove 5. The arc surface on the expansion member 4 located in the release groove 5 contacts the arc surface of the release member 6 and receives an upward component force, thereby causing the expansion member 4 to move into the first fixing groove 202 until it returns to the initial position.

[0028] The second mounting body 3 has a groove 302 on its periphery, and a retaining ball 303 is elastically connected in the groove 302. In this embodiment, a spring connection is used. In the initial state, a part of the retaining ball 303 extends out of the groove 302. The wall of the mounting hole 201 is provided with a retaining groove 203 that cooperates with the retaining ball 303. The retaining ball 303 and the retaining groove 203 are configured such that when the baffle 1 is in the blocking position, the retaining ball 303 enters the retaining groove 203.

[0029] When the baffle 1 rotates to the blocking position, the retaining ball 303 enters the retaining groove 203, so that the baffle 1 is in a "soft fixed" state, that is, a large external force is required to make the baffle 1 rotate. This is used before the manganese-iron alloy is cast, when the temperature has not yet risen to the point where the expansion part 4 enters the second fixed groove 301. It plays a positioning role of the baffle 1 and prevents the expansion part 4 from being blocked by the rotation and displacement of the baffle 1 during the temperature rise process.

[0030] In this embodiment, a sealing block 304 is detachably installed at the end of the second mounting body 3 away from the baffle 1. The size of the sealing block 304 is larger than that of the mounting hole 201. After the second mounting body 3 is inserted into the mounting hole 201, it will continue to extend beyond the mounting hole 201. Installing the sealing block 304 at this time can prevent the second mounting body 3 from falling off during operation. The sealing block 304 and the second mounting body 3 are preferably connected by threads to facilitate disassembly and replacement. The outer surface of the sealing block 304 is designed with anti-slip texture to increase friction during operation and ensure that the installation and disassembly process is more convenient.

[0031] In this embodiment, a second mounting body 3 is provided on both sides of the baffle 1, and two first mounting bodies 2 are provided at the positions where the baffle 1 is installed in the furnace body, with each first mounting body 2 corresponding to one second mounting body 3. This arrangement ensures that both sides of the baffle 1 have a mounting and dismounting device for the manganese-iron alloy casting anti-splash baffle 1 of this utility model, making the force on both sides of the baffle 1 uniform, thereby effectively avoiding tilting or loosening caused by uneven force on one side. This symmetrical design not only improves the stability of the baffle 1 during use, but also better adapts to thermal expansion and contraction changes under high-temperature environments. In addition, the evenly distributed mounting structure on both sides also helps to simplify installation and disassembly operations, making maintenance more efficient. Through this design, the overall reliability and durability of the device are further enhanced, meeting the requirements for precise control during the casting of manganese-iron alloy.

[0032] Furthermore, both sides of the baffle 1 are provided with mounting grooves 101, and the second mounting body 3 is elastically connected in the mounting groove 101. The second mounting body 3 is configured such that: in the initial state, the second mounting body 3 extends out of the mounting groove 101 and can cooperate with the first mounting body 2 and the sealing block 304; in the compressed state, the second mounting body 3 enters the mounting groove 101.

[0033] During installation, the second mounting body 3 is pressed into the mounting groove 101, and then the baffle 1 is placed in the installation position. At this time, the second mounting body 3 pops out under the action of the elastic connection and enters the mounting hole 201. To remove the baffle 1, first remove the sealing block 304, then press the second mounting body 3 into the mounting groove 101, and the baffle 1 can be removed. This design not only simplifies the installation steps but also effectively avoids installation failure due to improper operation. Through the elastic connection design, the second mounting body 3 can automatically spring back after being subjected to force, ensuring its precise fit with the first mounting body 2 and the sealing block 304, thereby improving the overall assembly efficiency. In addition, this structural design can also adapt to different sizes of mounting holes 201 to a certain extent, enhancing the versatility and flexibility of the device.

[0034] Furthermore, the edge of the second mounting body 3 furthest from the mounting groove 101 has a rounded transition. During installation, the rounded surface of the second mounting body 3 first contacts the side wall of the first mounting body 2, causing the second mounting body 3 to be subjected to pressure into the mounting groove 101, thus allowing the second mounting body 3 to break through the elastic force of the elastic connection and enter the mounting groove 101. This design only requires pressing the baffle 1 downward between the two first mounting bodies 2 during installation, and the second mounting body 3 automatically enters the mounting hole 201, simplifying the operation process. The rounded transition design not only improves the smoothness of installation but also effectively reduces the friction between the side wall of the second mounting body 3 and the side wall of the first mounting body 2, thereby extending the service life of the device.

[0035] In this embodiment, an oil filling hole 8 is provided above the first mounting body 2, extending into the mounting hole 201. Normally, lubricating oil needs to be applied between the mounting hole 201 and the second mounting component to ensure smoother rotation of the second mounting component. The lubricating oil needs to be replenished periodically. When replenishing the lubricating oil, simply introduce the lubricating oil into the oil filling hole 8, allowing it to flow into the mounting hole 201 under gravity. Then, by rotating the baffle 1, the second mounting component rotates, allowing the lubricating oil to spread throughout the entire mounting hole 201. This design eliminates the need to disassemble the baffle 1 when adding lubricating oil, greatly simplifying the maintenance process and reducing the risk of wear or damage to parts due to frequent disassembly. Furthermore, the oil filling hole 8 is designed with a dustproof function, featuring a removable sealing plug that effectively prevents external impurities from entering the mounting hole 201, thus ensuring the purity and lubrication effect of the lubricating oil. This design not only reduces maintenance costs but also improves overall work efficiency.
