Description

Technical Field

[0001] This utility model relates to the technical field of crucible fixing equipment, and in particular to a crucible fixing device for the production of vanadium-nitrogen alloys. Background Technology

[0002] Vanadium-nitrogen alloys are alloys primarily composed of vanadium (V) and nitrogen (N), widely used in the steel industry, especially in the production of high-strength, corrosion-resistant, and high-temperature steels. The main function of vanadium-nitrogen alloys is as alloying elements added to steel to improve its strength, hardness, toughness, and wear resistance. Vanadium can promote grain refinement in steel, enhancing its mechanical properties, particularly its stability at high temperatures.

[0003] In the production of vanadium-nitrogen alloys, high-temperature smelting is one of the core processes. When using crucibles for smelting, the stability and support height of the crucibles have a significant impact on production efficiency and safety. Currently, most traditional crucible fixing equipment uses fixed brackets or mechanical means to support the crucibles. Although these support structures can stably fix the crucibles on the ground, during the smelting process, these support structures cannot flexibly adjust the support height of the crucibles according to actual needs, making it inconvenient to flexibly adjust their placement. Furthermore, they also hinder the removal of the high-temperature smelted vanadium-nitrogen alloy from the crucible, thus presenting certain limitations in their use.

[0004] Based on this, we propose a crucible fixing device for vanadium-nitrogen alloy production to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a crucible fixing device for vanadium-nitrogen alloy production, which can solve the problems of traditional crucible fixing devices being unable to flexibly adjust the support height and placement position, and being inconvenient for discharging high-temperature smelting vanadium-nitrogen alloys.

[0007] To solve the above-mentioned technical problems, this utility model provides a crucible fixing device for vanadium-nitrogen alloy production, which adopts the following technical solution: it includes a mobile trolley, the top of which is connected to a scissor lift frame, and the top of the scissor lift frame is also equipped with a crucible fixing assembly. The crucible fixing assembly includes a support adjustment assembly, and the top of the support adjustment assembly is connected to a crucible body for vanadium-nitrogen alloy smelting.

[0008] The support adjustment assembly includes a first support base plate, a second support base plate is hinged to the top of the first support base plate, push handles are respectively connected to both sides of one end of the second support base plate, and a fixed base is also installed at the end of the second support base plate away from the push handles.

[0009] Optionally, the fixed base has an electric heating groove inside, and the electric heating groove has a card interface on both sides inside.

[0010] Optionally, an electric heater is connected to the bottom of the crucible body. The electric heater is matched with the structure of the electric heating tank. A snap-fit ​​block is installed on both sides of the electric heater. The snap-fit ​​block is matched with the snap-fit ​​interface structure. The snap-fit ​​block and the snap-fit ​​interface are engaged in a snap-fit ​​fit.

[0011] Optionally, the crucible body is provided with lifting handles on both sides of the top, and a pouring outlet is provided on the side of the crucible body away from the lifting handles.

[0012] Optionally, one end of the mobile cart is connected to a mobile push handle, and a voltage control cabinet is installed at the end of the mobile cart near the mobile push handle. An electric push rod is connected to the bottom of the voltage control cabinet, and the electric push rod is connected to the scissor lift frame by a transmission connection.

[0013] Optionally, the voltage control cabinet has an adjustable limit frame on one side, and one end of the adjustable limit frame is connected to the bottom of the first support base plate with a hinge seat. The hinge seat and the scissor lift frame are hinged together.

[0014] In summary, this utility model has at least one of the following beneficial effects:

[0015] 1. This solution utilizes a scissor lift frame hinged between the mobile trolley and the crucible fixing assembly, along with an electric push rod installed at the bottom of the voltage control cabinet, to adjust the support height of the crucible fixing assembly. The transmission connection between the electric push rod and the scissor lift frame allows the electric push rod to extend or retract the scissor lift frame when energized, thereby adjusting the support height. When the scissor lift frame is extended, the support height of the mobile trolley on the crucible fixing assembly is increased; when the scissor lift frame is retracted, its support height is decreased. As can be seen from the above, the crucible fixing equipment designed in this solution can flexibly adjust the support height and position of the crucible fixing assembly as needed, thus improving the flexibility of the equipment in the field of crucible fixing.

[0016] 2. The crucible fixing assembly in this solution mainly consists of a support and adjustment assembly and a crucible body. The support and adjustment assembly, through a snap-fit ​​design between the snap-fit ​​block and the snap-fit ​​interface, can fix the crucible body used for high-temperature smelting of vanadium-nitrogen alloys to the top of the second support base plate. After the vanadium-nitrogen alloy has melted inside the crucible body, the crucible body can be lifted upwards using the hinge structure between the first and second support base plates and the combination of the push-top handle. The lifted crucible body can tilt to one side, facilitating the smooth discharge of the high-temperature vanadium-nitrogen alloy inside. As can be seen from the above, the crucible fixing device designed in this solution can stably fix the crucible body to the top of the support and adjustment assembly. This support and adjustment assembly can also tilt the stably installed crucible body according to usage conditions to facilitate the discharge of the high-temperature vanadium-nitrogen alloy inside the crucible body.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example: Refer to Figures 1 to 5 This utility model provides an embodiment of a crucible fixing device for vanadium-nitrogen alloy production, comprising a mobile trolley 1, a scissor lift frame 2 connected to the top of the mobile trolley 1, a crucible fixing assembly 3 installed on the top of the scissor lift frame 2, a support and adjustment assembly 3 including a support and adjustment assembly 4, a crucible body 5 for vanadium-nitrogen alloy smelting connected to the top of the support and adjustment assembly 4, a first support base plate 6, a second support base plate 7 hinged to the top of the first support base plate 6, push handles 8 connected to both sides of one end of the second support base plate 7, and a fixing base 9 installed at the end of the second support base plate 7 away from the push handles 8. This crucible fixing device allows for flexible adjustment of the support height and placement position of the crucible fixing assembly 3 for vanadium-nitrogen alloy production according to usage conditions, and can stably fix the crucible body 5 on the top of the support and adjustment assembly 4. The support and adjustment assembly 4 can also tilt the stably installed crucible body 5 according to usage conditions to facilitate the discharge of the high-temperature vanadium-nitrogen alloy inside the crucible body 5.

[0026] An electric heating groove 10 is provided inside the fixed base 9. Snap-fit ​​interfaces 11 are provided on both sides of the electric heating groove 10. The crucible body 5 can be connected and fixed to the top of the second support base 7 via the electric heating groove 10 and snap-fit ​​interfaces 11 inside the fixed base 9. An electric heater 12 is connected to the bottom of the crucible body 5. The electric heater 12 is structurally compatible with the electric heating groove 10. Snap-fit ​​blocks 13 are installed on both sides of the electric heater 12. The snap-fit ​​blocks 13 are structurally compatible with the snap-fit ​​interfaces 11. The two parts are connected by a snap-fit ​​mechanism. The snap-fit ​​mechanism between the snap-fit ​​block 13 and the snap-fit ​​interface 11 facilitates the fixation of the crucible body 5 on the top of the second support base plate 7. The crucible body 5 can also be installed and disassembled according to the usage. Both sides of the top of the crucible body 5 are provided with lifting handles 14. The side of the crucible body 5 away from the lifting handles 14 is also provided with a casting outlet 15. The casting outlet 15 added to one side of the crucible body 5 facilitates the discharge of the high-temperature molten vanadium-nitrogen alloy inside the crucible body 5.

[0027] One end of the mobile cart 1 is connected to a mobile push handle 16. A voltage control cabinet 17 is installed at the end of the mobile cart 1 near the mobile push handle 16. An electric push rod 18 is connected to the bottom of the voltage control cabinet 17. The electric push rod 18 is connected to the scissor lift frame 2 by transmission. Through the structural design of the transmission connection between the electric push rod 18 and the scissor lift frame 2, when the electric push rod 18 is powered on, it can drive the scissor lift frame 2 to expand or retract between the mobile cart 1 and the crucible fixing assembly 3. One side of the voltage control cabinet 17 is an adjustment limit frame 19. One end of the adjustment limit frame 19 is connected to the bottom of the first support base plate 6 by a hinge seat 20. The hinge seat 20 and the scissor lift frame 2 are hinged together. Through the structural design of the hinge seat 20 and the scissor lift frame 2, the scissor lift frame 2 can be movably hinged between the mobile cart 1 and the crucible fixing assembly 3.

[0028] Working Principle: This solution utilizes a scissor lift frame 2 hinged between the mobile trolley 1 and the crucible fixing assembly 3, and an electric push rod 18 installed at the bottom of the voltage control cabinet 17. Since the electric push rod 18 and the scissor lift frame 2 are connected by a transmission mechanism, when the electric push rod 18 is energized, it can drive the scissor lift frame 2 to expand or retract between the mobile trolley 1 and the crucible fixing assembly 3. Expanding the scissor lift frame 2 increases the support height of the mobile trolley 1 on the crucible fixing assembly 3; similarly, retracting the scissor lift frame 2 decreases the support height of the mobile trolley 1 on the crucible fixing assembly 3. Therefore, the crucible fixing equipment designed in this solution allows for flexible adjustment of the support height and placement position of the crucible fixing assembly 3 used in vanadium-nitrogen alloy production, depending on the application.

[0029] The crucible fixing assembly 3 in this solution mainly consists of a support and adjustment assembly 4 and a crucible body 5. The support and adjustment assembly 4 mainly consists of a first support base plate 6, a second support base plate 7, a push handle 8, and a fixing base 9. The fixing base 9 has an internally opened electric heating groove 10 and a snap-fit ​​interface 11, as well as an electric heater 12 and a snap-fit ​​block 13 installed at the bottom of the crucible body 5. Because the electric heater 12 and the electric heating groove 10 are structurally matched, and the snap-fit ​​block 13 and the snap-fit ​​interface 11 are snap-fitted together, the crucible body 5 can be fixed in place. The crucible body 5 is fixed at the top of the second support base plate 7. After the vanadium-nitrogen alloy is melted at high temperature inside the crucible body 5, the crucible body 5 installed on the top of the second support base plate 7 can be lifted upward by the hinged connection between the first support base plate 6 and the second support base plate 7, and the push-holding rods 8 installed on both sides of one end of the second support base plate 7. The upward lifting of the second support base plate 7 can make the crucible body 5 installed on the top tilted. The tilted crucible body 5 facilitates the discharge of the vanadium-nitrogen alloy melted at high temperature inside.
