Description

Technical Field

[0001] The utility model relates to the field of metallurgical equipment, in particular to an integrated tilting electric furnace equipment for smelting ferrovanadium. Background Art

[0002] With the increasing demand for ferrovanadium, traditional smelting methods are no longer able to meet the production requirements of high efficiency, low consumption, and environmental protection. As an advanced smelting equipment, the tilting electric furnace has gradually become an important choice for ferrovanadium smelting due to its ability to flexibly control the smelting process and improve smelting efficiency and quality.

[0003] Tilt-type electric furnaces integrate advanced technologies such as arc heating, tilting tapping, and automated control. They enable rapid melting and alloying of raw materials while facilitating slag and iron separation and subsequent processing. Furthermore, they offer high thermal efficiency and energy utilization, helping to reduce production costs. With the continuous advancement of metallurgical technology and increasingly stringent environmental protection requirements, the application of tilt-type electric furnaces in ferrovanadium smelting will become even more widespread. In the future, tilt-type electric furnaces will develop towards larger, more intelligent, and more environmentally friendly designs to further improve smelting efficiency, reduce energy consumption, and minimize environmental pollution.

[0004] However, complex raw materials react violently during the smelting process, and the service life of the water-cooled furnace cover is short. Metal splashing and bonding burnout occur during the smelting process, leading to cracks and leakage in the welds of the internal circulating water pipes. The violent reaction of the materials during the smelting process can cause the slag outlet water tank to burst. There is also the possibility of the final stage of the tilting furnace slag discharge process causing the slag to reflux and burn the furnace frame. During operation, the centripetal force during the operation of the furnace cover rotation mechanism may damage the guide wheel through the cover and cause it to become stuck. Graphite electrodes may also slip and break during the iron and slag discharge process. The resulting wear and tear requires regular maintenance and replacement of parts, increasing maintenance costs. Utility Model Content

[0051] It should be understood that the embodiments of the present invention shown in the exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in the present invention, it is readily apparent to those skilled in the art that various modifications are possible without departing substantially from the teachings of the present invention. Accordingly, all such modifications are intended to be included within the scope of the present invention. Other substitutions, modifications, variations, and deletions may be made to the design, operating conditions, and parameters of the following exemplary embodiments without departing from the spirit of the present invention.

[0052] The utility model provides an integrated tilting electric furnace for smelting vanadium iron. Figure 1 , including: a furnace body 1, a furnace frame 2, a furnace cover rotating support 3, a center cover ring 4 and a water-cooled furnace cover 5; the furnace body 1 is located on the furnace frame 2, the water-cooled furnace cover 5 is arranged above the furnace body 1, and the center cover ring 4 is arranged above the water-cooled furnace cover 5; a bracket is arranged on the side extension of the furnace frame 2, which is used to connect one end of the furnace cover rotating support 3, and the other end of the furnace cover rotating support 3 is connected to the water-cooled furnace cover 5; a sleeve is sleeved on the furnace body 1.

[0053] By improving the tilting furnace, this utility model enables rapid addition of raw materials and efficient removal of waste slag, improving smelting efficiency, facilitating uniform temperature distribution within the furnace, and increasing ferrovanadium yield. It also offers improved environmental performance and reduces waste gas and slag emissions. By achieving integration, the equipment's operating efficiency is improved, while operating difficulty and maintenance costs are reduced. During the ferrovanadium smelting process, the integrated tilting furnace equipment enables full automation of the entire process, from raw material processing and smelting process control to product output.

[0054] In some embodiments, see Figure 4 , the furnace cover rotation support 3 includes a rotation positioning mechanism, a water cooling mechanism and a support mechanism;

[0055] The rotation positioning mechanism is sleeved in the supporting mechanism, and the water cooling mechanism is located above the supporting mechanism.

[0056] The furnace cover rotation support 3 is used to support the entire water cooling mechanism to facilitate cooling. At the same time, with the help of the rotation positioning mechanism, the problem of jamming during rotation is avoided.

[0057] In some embodiments, see Figure 4 , the rotation positioning mechanism includes an L-shaped guide wheel 311, a positioning ring 312, a distance ring 313, a horizontal bearing 314 and a connecting shaft 315;

[0058] The connecting shaft 315 is sleeved in the positioning ring 312 and the distance ring 313;

[0059] A horizontal bearing 314 is provided between the positioning ring 312 and the distance ring 313;

[0060] An L-shaped guide wheel 311 is provided outside the horizontal bearing 314 , and the horizontal bearing 314 is located in the vacant portion of the L-shaped guide wheel 311 .

[0061] In order to solve the problem of furnace cover rotation mechanism failure in the pre-furnace smelting preparation stage, an "L" guide wheel is used to replace the original design of the wheel without flange. The L-shaped structure provides a larger support area and stability, which helps to reduce vibration and deviation, and overcome the centripetal force damage to the guide wheel during the operation of the furnace cover rotation mechanism, which may cause the cover to become stuck.

[0062] The positioning ring 312 and the distance ring 313 can ensure accurate alignment between the various parts, thereby improving the overall accuracy and stability of the rotation positioning mechanism. They also serve as fasteners to fix the L-shaped guide wheel 311 and enhance the stability of the rotation positioning mechanism.

[0063] In some embodiments, see Figure 4 , the water cooling mechanism includes a water cooling pipe 321, a water cooling bracket 322, a side circulation pipe 323 and a water outlet 324;

[0064] The water cooling pipe 321 and the side circulation pipe 323 are connected and are located together in the water cooling bracket 322;

[0065] One end of the water cooling pipe 321 is connected to the water outlet 324 .

[0066] The side circulation pipe 323 is responsible for leading the cooling medium out of the water-cooling pipe 321, passing through the external heat dissipation equipment and then returning to the water-cooling pipe 321, forming a closed cycle. Through the side circulation pipe 323, the cooling medium can fully exchange heat with the external environment, thereby further improving the heat dissipation effect.

[0067] In some embodiments, see Figure 4 , the support mechanism includes a support seat 331, a rotary bearing 332 and a sag adjustment surface 333;

[0068] The support seat 331 is located above the connecting shaft 315;

[0069] The rotary bearing 332 passes through the connecting shaft 315 and the bracket provided on the side of the furnace frame 2;

[0070] A sag adjustment surface 333 is provided on the top of the support base 331 , and the water cooling bracket 322 is connected above the sag adjustment surface 333 .

[0071] When the rotating bearing 332 passes through the bracket connecting the shaft 315 and the furnace frame 2, it can effectively fix and support the entire furnace cover rotating support to prevent it from shaking or shifting during rotation. At the same time, it can also simplify the structure of the furnace cover rotating support and facilitate disassembly and installation during maintenance.

[0072] In some embodiments, see Figure 7 The holding ring 6 includes a balancing positioning seat 61 and a rigid positioning pin 62, which are used to constrain the graphite electrode.

[0073] The balanced positioning seat 61 and the rigid positioning pin 62 are used to strengthen the circumferential constraint of the holding ring 6, thereby eliminating the graphite electrode slippage during the smelting process and the graphite electrode breakage during the iron and slag tapping processes. The invention has a wide range of applications, low cost, and great social and economic benefits.

[0074] In some embodiments, see Figure 2 The bushing includes a graphite bushing 71, an explosion-proof bushing 72 and a corundum casting lining 73.

[0075] As a protective layer for the furnace body 1, the liner can effectively reduce heat loss from the furnace body 1 to the outside world and improve the thermal efficiency of the furnace. This is particularly important for the electric furnace smelting process, because the energy consumption of the electric furnace mainly comes from the process of converting electrical energy into thermal energy. Reducing heat loss means efficient utilization of energy. During the smelting process, the high temperature, slag, and molten metal in the furnace can all cause corrosion to the furnace body 1. The liner acts as a barrier, effectively isolating these corrosive factors and protecting the furnace body 1 from damage, thereby extending the service life of the furnace body 1.

[0076] The graphite bushing 71 not only has excellent high-temperature resistance but also possesses high corrosion resistance, significantly improving the durability of the furnace lining and reducing replacement frequency and maintenance costs. It protects the furnace body 1 as the target product passes through the taphole, and changes the taphole's shape from circular to square, increasing its cross-sectional area.

[0077] The presence of the explosion-proof bushing 72 helps stabilize the furnace environment and reduces smelting instability factors caused by temperature changes or structural deformation of the furnace body 1. This helps to improve the stability and reliability of the smelting process and ensure the consistency of product quality.

[0078] Corundum, the primary component of the castable, has a melting point of up to 2050°C, enabling the corundum cast lining 73 to withstand extremely high temperatures without melting or deforming. During high-temperature processes such as ferrovanadium smelting, the corundum cast lining 73 maintains a stable structure and performance, providing a reliable protective layer for the furnace body 1.

[0079] In some embodiments, see Figure 3 The crossbeam 21 of the furnace frame 2 is filled with magnesia and corundum slag particles.

[0080] An arc frame 22 is provided in the furnace frame 2 for supporting the furnace body 1 , and a positioning pin 23 is provided at the bottom of the arc frame 22 , one end of the positioning pin 23 is connected to a track 24 .

[0081] In order to solve the problem of residual slag backflow and burning the grate 2 in the final stage of the tilting furnace slag discharge process, the method of filling the crossbeam 21 with magnesia + corundum slag particles is adopted to avoid the high-temperature liquid residue burning and burning through the crossbeam to improve the safety of the equipment body.

[0082] The addition of magnesia and corundum slag particles increases the density of the material within beam 21, reducing the formation of pores and cracks. This structural reinforcement helps improve the crossbeam 21's mechanical properties, such as compression and bending resistance, allowing it to withstand greater loads and impacts. Both magnesia and corundum slag particles have excellent thermal insulation properties, reducing heat transfer from crossbeam 21 to the outside world. This helps reduce heat loss during the smelting process and improves energy efficiency.

[0083] The curved frame 22 distributes the weight of the furnace body 1 more evenly across the frame 2, avoiding localized stress caused by concentrated weight. This distribution enhances overall structural stability and reduces the risk of damage from vibration or impact. The curved structure possesses inherent compressive and tensile properties, making it more resilient to the forces and moments transmitted from the furnace body 1. This significantly enhances the supporting strength of the frame 2, ensuring safe and stable operation of the furnace body 1 during the smelting process.

[0084] During the smelting process, the furnace body 1 generates a large amount of heat, resulting in temperature fluctuations. These temperature fluctuations can generate thermal stress between the furnace body 1 and the furnace frame 2. The design of the curved frame 22 helps optimize the distribution of thermal stress and reduce deformation or cracking caused by concentrated thermal stress. The curved structure provides good adaptability to thermal expansion. As the furnace body 1 expands due to heat, the curved frame can adapt to this change, thereby reducing the restraining force on the connection between the furnace body 1 and the furnace frame 2.

[0085] The connection between the locating pins 23 and the rails 24 further enhances the stability of the oven frame 2. The locating pins 23 ensure the accurate positioning of the curved frame 22 on the rails 24, preventing it from moving or deforming during use. By adjusting the position of the locating pins 23 on the rails 24, the angle and height of the curved frame 22 can be easily adjusted.

[0086] In some embodiments, see Figure 4 , the diameter of the center cover ring 4 is 2320mm±100mm;

[0087] The center cover ring 4 is cast without water and is provided with an A-phase electrode hole 41 , a B-phase electrode hole 42 , a C-phase electrode hole 43 and an inclined feeding hole 44 for feeding materials and graphite electrodes.

[0088] In some embodiments, see Figure 5 , the diameter of the center cover ring 4 is 2320mm±100mm;

[0089] The center cover ring 4 is cast without water and is provided with an A-phase electrode hole 41 , a B-phase electrode hole 42 , a C-phase electrode hole 43 and an inclined feeding hole 44 for feeding materials and graphite electrodes.

[0090] The design of the A-phase, B-phase, and C-phase electrode holes allows the graphite electrodes to be quickly and accurately positioned and installed in the corresponding positions, reducing the time and difficulty of electrode installation, thereby improving production efficiency. Precise electrode hole positioning reduces vibration and offset of the electrodes during operation, thereby improving the stability and reliability of the equipment.

[0091] The inclined feeding hole 44 allows the feeding direction and angle of the electrode to be flexibly adjusted.

[0092] The use of an anhydrous center cover ring 4 greatly reduces the failure rate of the original water-cooled center cover ring 4 and improves the stability of the ferrovanadium smelting process. The diameter of the center cover ring 4 is optimized. The diameter of the original water-cooled cover ring is changed from 2800mm to 2320mm. The anhydrous cast composite center cover ring 4 reduces heat loss. In some embodiments, please refer to Figure 6 The diameters of the upper circulation pipe 51 and the lower circulation pipe 52 in the water-cooled furnace cover 5 are 945 mm ± 5 mm.

[0093] Complex raw materials react violently during the smelting process, and the original design of the water-cooled furnace cover 5 has a short service life. Metal splashing and bonding burning occur during the smelting process, resulting in cracks and leakage in the welds of the internal circulating water pipes. For this reason, the height of the upper circulation pipe 51 and the lower circulation pipe 52 of the original water-cooled furnace cover 5 were changed from 705mm to 945mm, which extended the service life of the water-cooled furnace cover 5; avoided splashing, molten metal bonding, weld burning deformation, cracks and other problems during the smelting process.

[0094] The above embodiments are possible examples of implementation of the present invention and are given only to enable those skilled in the art to clearly understand the principles of the present invention. Those skilled in the art should understand that the above discussion of any embodiment is merely exemplary and is not intended to imply that the scope disclosed in the embodiments of the present invention, including the claims, is limited to these examples. Under the overall concept of the present invention, the technical features in the above embodiments or different embodiments can also be combined with each other to produce many other changes in different aspects of the embodiments of the present invention as described above, which are not provided in the specific implementation for the sake of simplicity.
