Description

Technical Field

[0001] This invention relates to the field of electrofused brick casting technology, specifically to a method and system for continuous electrofused brick casting. Background Technology

[0002] As a high-performance refractory material, fused refractory bricks are manufactured through a core process where raw materials such as quartz sand, alumina, sodium carbonate, and strontium carbonate are melted into a homogeneous melt at extreme high temperatures of 1800℃ to 2400℃ in an electric arc furnace. The melt is then cast into a specific mold and subjected to slow cooling, annealing, and machining. These bricks are widely used in key lining parts of high-temperature industrial equipment such as glass kilns, iron and steel smelting furnaces, non-ferrous metal smelting furnaces, and chemical reactors due to their high density, excellent strength at both room and high temperatures, strong resistance to slag erosion, and outstanding thermal stability. Their quality directly determines the service life and operational safety of industrial furnaces and kilns.

[0003] In the large-scale production of electrofused bricks, to improve production efficiency and raw material utilization, the industry generally adopts a continuous casting process. This means that multiple sets of molds need to be cast sequentially from one batch of molten raw materials. However, the interval between the completion of the previous set of sand mold casting and the start of the next set requires a large number of personnel and related equipment such as cranes to assist in changing the sand molds. This interval is affected by factors such as the sand mold changing speed, gate calibration, equipment parameter adjustment, and the operator's proficiency, and generally ranges from 5 to 15 minutes. In some complex conditions, it can even be extended to more than 20 minutes, constituting a casting delay. The problems caused by the continuous heat dissipation of the melt lead to a series of negative chain reactions on the characteristics of the melt and the final quality of the brick. The continuous heat dissipation of the melt reduces the fluidity and the integrity of the pouring and filling. During the residence period, the contact time between the melt and the air is prolonged, and easily oxidized elements will react with oxygen to generate low-melting-point oxidation products, which reduces the high-temperature stability of the brick. In addition, the flow trajectory of the melt at the beginning, the continuous pouring and the end of the pouring are dynamically changing. This causes the sand molds that are continuously suspended by the crane or placed on the ground to not only have a certain amount of melt overflow and splashing during the pouring, but also to pose safety hazards to the surrounding auxiliary personnel and the environment.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0013] Furthermore, the driven slider has an extension sleeve at its bottom that slides and engages with the limiting shaft, and the central turntable has a semi-circular arc-shaped cavity at its center, with a traction wire connected to the limiting counterweight block inside the arc-shaped cavity.

[0014] Furthermore, the bottom of the side adjustment frame is provided with a lifting hydraulic cylinder arm that is sleeved inside the side wing track groove. The bottom outer wall of the side adjustment frame is provided with a side adjustment slider that slides in cooperation with the side wing track groove.

[0016] A method for continuous casting of fused bricks includes the following steps:

[0017] During the feeding stage, the sand mold is transported in an orderly manner to the casting rotary table via the feeding conveyor. The casting rotary table then uses the on-board splicing guide to initially move the sand mold laterally to receive and transfer it.

[0018] During the adjustment phase, the sand mold initially placed on the surface of the splicing guide frame on the platform is adjusted horizontally and left-right using the side adjustment and matching frame.

[0019] During the pouring stage, based on the cooperation of the platform splicing guide frame with the front grab hook and the rear baffle, the current position of the sand mold is adjusted by the landing point auxiliary frame to adapt to the landing point trajectory that guides the flow of molten material when the gate is tilted, so as to complete the precise pouring.

[0020] During the unloading stage, the poured sand mold is deflected and brought closer to the unloading conveyor frame by axial rotation of the pouring rotary table, thus completing the continuous operation trajectory of single-mold sand mold pouring.

[0021] The beneficial effects of this invention are:

[0022] 1. This invention utilizes a ring-array platform splicing guide design on a casting rotary table, combined with the coordinated operation of the feeding conveyor and the unloading conveyor, to achieve a continuous operation mode where the casting of one set of sand molds is synchronized with the pre-positioning and adjustment of the next set of sand molds. This significantly shortens the sand mold replacement interval and avoids problems such as reduced heat dissipation and fluidity of molten material due to prolonged retention, and the generation of low-melting-point oxidation products from easily oxidized elements. It significantly improves the core qualities of electrofused bricks, such as density and high-temperature stability, while reducing reliance on manual labor and auxiliary equipment such as cranes, thus lowering the intensity of manual operation and equipment scheduling costs.

[0023] 2. This invention constructs a full-process sand mold positioning and calibration system through a linkage control mechanism of a platform splicing guide frame, a front grab hook, a rear baffle, a side adjustment frame, and a landing point auxiliary frame. The side adjustment frame identifies and adjusts the sand mold placement deviation in a timely manner by detecting the sliding rod. The front grab hook and the rear baffle form a two-way limiting fixation. The landing point auxiliary frame adjusts the sand mold position in real time according to the inclination angle of the gate, ensuring that the landing point of the molten material parabola always accurately matches the sand mold opening. This eliminates molten material splashing waste from the source, removes safety hazards to operators and the surrounding environment, and improves the utilization rate of raw materials and the integrity of pouring and filling.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1: Please refer to Figure 1 - Figure 14 As shown in the figure, this embodiment is a method and system for continuous casting of electrofused bricks, as detailed below:

[0042] During the feeding stage, the sand mold is transported in an orderly manner to the casting rotary table 1 via the feeding conveyor 3. The casting rotary table 1 then initially moves the sand mold laterally forward via the on-platform splicing guide 2 to receive and transfer it. A rotating shaft 101 is set in the middle of the casting rotary table 1. Several sets of casting fan plates 103 are arranged in a ring array on the top of the outer periphery of the rotating shaft 101. Support beam plates 102 that cooperate with and connect to the rotating shaft 101 are set between the bottoms of adjacent casting fan plates 103. Multiple sets of central track grooves 104 that are horizontally aligned with the feeding conveyor 3 are set in the center of the top of the casting fan plate 103. Multiple sets of side track grooves 105 and 106 that are horizontally and vertically aligned with the central track grooves 104 are set on both sides of the top of the casting fan plate 103. A guide intermediate slide groove 107 that cooperates with the rear baffle 8 is set on the inner wall of the central track groove 104. The feeding conveyor 3 and the unloading conveyor 4 are respectively arranged around the outer periphery of the casting rotary table 1.

[0043] During continuous casting, pre-made sand molds are sequentially hoisted onto the feeding conveyor 3, which then transports them in an orderly manner to the pouring rotary table 1. When the first set of sand molds approaches the pouring rotary table 1, the pouring rotary table 1 rotates and is adjusted so that the platform splicing guide 2 on one set of pouring fan plates 103 is horizontally aligned with the feeding conveyor 3. The pouring fan plate 103 is internally fitted with a drive motor that is connected to the guide roller 201. This drive motor is used to drive the guide roller 201 to run at the same frequency as the feeding conveyor 3 or the unloading conveyor 4, thereby completing the active traction during the feeding and unloading of the sand molds. It should be noted that a clutch is provided between the drive motor and the guide roller 201 for adjustment of connection and disconnection according to the pouring needs.

[0044] During the adjustment phase, the sand mold initially placed on the surface of the splicing guide frame 2 on the platform is adjusted laterally by the side adjustment frame 5. The bottom of the side adjustment frame 5 is equipped with a lifting hydraulic cylinder arm 501 that fits inside the side wing track groove 105. The bottom outer wall of the side adjustment frame 5 is equipped with a side adjustment slider that slides in cooperation with the side wing track groove 105. The side wing track groove 105 is equipped with a side wing hydraulic push rod 1 that cooperates with the side adjustment slider. The top of the lifting hydraulic cylinder arm 501 is equipped with a lifting support plate 502 facing the splicing guide frame 2 on the platform. The top of the lifting support plate 502 is equipped with an adjusting support plate 503. The middle of the adjusting support plate 503 is fitted with a detection slide rod 504 facing the splicing guide frame 2 on the platform. The tip of the detection slide rod 504 is fitted with a detection ball 505. The detection ball 505 is equipped with a pressure sensor.

[0045] In the sand mold alignment and adjustment zone where the sand mold has just been transferred to the surface of the splicing guide 2 on the platform, the side adjustment frame 5 is axially slid closer to the sand mold by the side hydraulic push rod 1. The adjustment plate 503 on the side adjustment frame 5 is pre-set to adjust the length of the rod extending towards the sand mold by the detection slide rod 504. The lifting hydraulic cylinder arm 501 drives the lifting plate 502 to slide up a certain distance, causing the detection ball 505 to contact the outer wall of the sand mold that has been transported. The contact pressure is detected synchronously by the pressure sensors built into multiple sets of detection balls 505. Based on whether the detected pressure is consistent, it is determined whether there is a misalignment in the current position of the sand mold on the splicing guide 2 on the platform. With the help of the surrounding auxiliary personnel, the lifting hydraulic cylinder arm 501 is further slid up, and the lifting plate 502 lifts and pushes the corner or the same side of the sand mold that is misaligned. The specific scheme is adjusted by the auxiliary personnel according to the current positional deviation of the sand mold, and is not limited to this.

[0046] Example 2: During the casting stage, based on the cooperation of the platform splicing guide 2, the front grab hook 6, and the rear baffle 8, the trajectory of the molten material flow is guided when the sand mold is tilted to achieve precise casting. A support guide 801 is provided at the bottom of the rear baffle 8. A traction adjustment frame 803 is provided on the surface of the support guide 801 facing the feeding conveyor 3. Lifting hydraulic cylinder arms 802 connected to the rear baffle 8 are sleeved on the two sides of the support guide 801 away from the traction adjustment frame 803. Moving sliding blocks 805 are symmetrically arranged on the outer wall of the traction adjustment frame 803. The traction adjustment frame 803 and the support guide 801... A transmission component box 807 is provided in the middle. A torque adjustment motor 806 that is connected to the transmission component box 807 is provided at the bottom of the traction adjustment frame 803. A torque adjustment shaft 804 that is fixedly connected to the limiting shaft 808 is sleeved through the middle of the traction adjustment frame 803. A sliding rectangular groove is provided through the middle of the limiting shaft 808, and a limiting tooth 809 is provided inside the sliding rectangular groove. A rack is provided at the top and bottom of the torque adjustment shaft 804. A magnetic coupling, gear and transmission short rod connected to the rack are provided inside the transmission component box 807, forming a drive link for the torque adjustment motor 806 to adjust the extension length of the torque adjustment shaft 804.

[0047] During the process of the sand mold being pulled and moved to the splicing guide frame 2 on the platform, within the sand mold straightening and adjustment zone, the rear baffle 8 first contacts the outer wall of the sand mold, and along with the continuous guiding movement of the sand mold by the guide roller 201 within the sand mold straightening and adjustment zone, it drives the rear baffle 8 to move synchronously along the splicing guide frame 2 on the platform. Combined with the guide intermediate slide groove 107 and the moving and cooperating slider 805, it ensures that the rear baffle 8 maintains a horizontal state and moves smoothly. The lifting hydraulic cylinder arm 802 drives the rear baffle 8 to adjust its longitudinal height to adapt to the current sand mold.

[0048] When the rear baffle 8 moves horizontally in sync with the rotating shaft 101, if the front grab hook 6 is still in a squeezed and deflected state, the rear baffle 8, through the support guide 801, drives the traction adjustment frame 803 and the limiting shaft 808 to maintain synchronous horizontal movement. When the sand mold moves past the front grab hook 6, and the front grab hook 6 rebounds and remains in an upright state, the front grab hook 6 is temporarily limited and locked by the limiting counterweight block 608 and the limiting shaft 808. Machine 806 drives the adjusting shaft 804 to move a distance equal to the length of the front gripper 6 in the direction of the rotating shaft 101. This distance is the distance from the claw tip of the front gripper 6 to the central turntable 601. The adjusting shaft 804 drags the limiting shaft 808 to keep them moving synchronously. The front gripper 6 is simultaneously pulled closer to the sand mold until the front gripper 6 contacts the outer wall of the sand mold, thus forming a limiting adjustment mechanism for the sand mold. The limiting adjustment mechanism is jointly constructed by the front gripper 6 and the rear baffle 8.

[0049] A central turntable 601 is provided in the middle of the front gripper hook 6. Driven sliders 602, which slide and cooperate with the inner guide groove 204, are provided on both sides of the central turntable 601. A central rotating shaft 603, which is sleeved with the central turntable 601, is provided in the middle of the driven sliders 602. A damping spiral spring 607, which cooperates with the central turntable 601, is provided on the shaft of the central rotating shaft 603. An auxiliary shaft 609 is provided on the outer wall of the shaft of the central rotating shaft 603. 9. An auxiliary gear 610 is provided on the surface to mesh with the limiting rack 203; the bottom of the driven slider 602 is provided with an extension sleeve 604 that slides and engages with the limiting shaft 808; a semi-circular arc-shaped wire cavity 605 is provided in the center of the central turntable 601; a traction wire 606 connected to the limiting counterweight block 608 is provided inside the arc-shaped wire cavity 605; and a block fitting groove is provided on the inner wall of the extension sleeve 604 to slide and engage with the limiting counterweight block 608.

[0050] like Figure 4-6 As shown, the front gripper 6 maintains an inclined vertical state towards the rotating shaft 101 without interference, and is located between the limiting rack 203 and the spring protrusion 202 within the sand mold straightening adjustment range. When the sand mold is transported through the initial position area of ​​the front gripper 6 by the splicing guide frame 2 on the platform, several sets of miniature rollers are provided on the claw surface of the front gripper 6 facing the feeding conveyor frame 3 to assist the sand mold in contacting the front gripper 6. Combined with the arc provided on the edge of the sand mold chassis and the limiting resistance of the spring protrusion 202 on the initial position of the front gripper 6, the front gripper 6 is squeezed and deflected along the central rotating shaft 603. The damping scroll spring 607 is compressed simultaneously. After the sand mold moves past the front gripper 6, the front gripper 6 is reset by the damping scroll spring 607 and maintains an upright state.

[0051] When the front gripper hook 6 is squeezed and deflected into the fitting slot, the rotation of the central turntable 601 causes the traction wire 606 to gradually slide down the limiting counterweight block 608 until the limiting counterweight block 608 disengages from the limiting tooth 809, thus achieving a temporary sliding engagement between the extension sleeve 604 and the limiting shaft 808. Meanwhile, the rear baffle 8 lengthens the distance between itself and the front gripper hook 6 as the sand mold continues to move. After the front gripper hook 6 resets, the traction wire 606 again drags the limiting counterweight block 608 upwards, maintaining a limiting engagement with the limiting tooth 809, thus causing the extension sleeve 604 and the limiting shaft 808 to engage. Rod 808 maintains a temporary limiting sleeve engagement. Similarly, after the sand mold is poured and transported close to the unloading conveyor frame 4, the adjusting motor 806 drives the adjusting shaft 804 and the limiting shaft 808 to move two lengths of the front grab hooks 6 towards the unloading conveyor frame 4, causing the front grab hooks 6 to disconnect from the sand mold in advance. When the front grab hooks 6 move horizontally in sync with the sand mold and the rear baffle 8 and approach the limiting rack 203, the limiting rack 203 engages with the auxiliary gear 610. As the front grab hooks 6 continue to move, the auxiliary gear 610 drives the central turntable 6 through the auxiliary shaft 609. 01 rotates towards the feeding conveyor frame 3. The rotation of the central turntable 601 synchronously drives the traction wire 606 to drag the limiting counterweight block 608 upward, causing it to disengage from the extension sleeve 604 and the limiting tooth 809, maintaining a temporary sliding fit. At the same time, the pitch adjustment motor 806 drives the pitch adjustment shaft 804 and the limiting shaft 808 to move towards the rotating shaft 101 through the accessories inside the transmission accessory box 807. This causes the distance between the rear baffle 8 and the front grab hook 6 to gradually shorten, and the sand mold is aligned by the rear baffle 8 and the sand mold straightening adjustment range with the actively driven guide roller 201. The material is pushed down to the unloading conveyor 4, from which it is transported to the next processing step for subsequent treatment such as heat preservation. It should be noted that the spring protrusion 202 has a replaceable damping spring inside. The part of the spring protrusion 202 exposed in the inner guide groove 204 is a hemispherical structure, which provides a certain damping for the movement of the driven slider 602. However, after the driven slider 602 is dragged to the upper limit of the force by the limiting shaft 808, the spring protrusion 202 is forced to squeeze the damping spring and sink into the inner wall of the inner guide groove 204. The gear structure is not limited to that shown in the attached figure and can be selected according to the implementation requirements.

[0052] The landing point auxiliary frame 7 has a synchronous slider 701 at its bottom that cooperates with the side wing track groove 106. The landing point auxiliary frame 7 has a passive pusher 702 at its top. The passive pusher 702 has a combined telescopic arm 703 hinged at its top. The combined telescopic arm 703 consists of a main arm and a secondary arm. The main arm has a spring component that cooperates with and connects to the secondary arm. The combined telescopic arm 703 has a rotary joint 704 hinged at its top. The rotary joint 704 has a limit sleeve 705 on its side wall. The rotary joint 704 consists of a micro motor, a reducer, and transmission components. It is responsible for transmitting rotational motion and bearing the load.

[0053] After the sand mold is clamped and limited by the front grab hook 6 and the rear baffle 8, it is pushed from the sand mold straightening adjustment zone to the sand mold landing point calibration zone by the guide roller 201. The initial unfolding angle of the combined telescopic arm 703 is adjusted in advance according to the sand mold to be processed. Guide posts are set on the top outer walls on both sides of the sand mold, such as... Figure 12 As shown, the combined telescopic boom 703 contacts the guide column and pushes the combined telescopic boom 703 and the passive pusher 702 to move laterally along the landing point auxiliary frame 7 until the sand mold is completely inside the sand mold landing point calibration range near the rotating shaft 101. This position is the trajectory of the molten material pouring down when the furnace charge is initially tilted during pouring. Figure 14 The furnace charge inlet body is shown as a dotted guide section. The main arm of the combined telescopic boom 703 extends the auxiliary arm via a built-in spring, causing the limiting sleeve 705 to approach the bottom of the furnace charge inlet. The distance between the limiting sleeve 705 and the bottom of the furnace charge inlet is adjusted by the rotating joint 704, ensuring that the limiting sleeve 705 makes contact with the bottom of the furnace charge inlet, forming a force application point. Figure 10 and Figure 12 As shown; the furnace charge inlet begins pouring and tilts downwards, as... Figure 14 As shown, the molten material gradually retracts from the landing point, and as the furnace charge opening tilts, it pushes the limiting sleeve 705. The limiting sleeve 705 drives the joint point between the combined telescopic arm 703 and the passive pusher 702 to deflect. With the guide column as the fulcrum, the combined telescopic arm 703 squeezes the guide column, causing the clamped sand mold to move laterally along the guide roller 201 towards the forward grab hook 6 within the sand mold landing point calibration range. This completes the coordinated adjustment of the sand mold and the furnace charge opening landing point. The adjustment distance is adjusted synchronously according to the tilt angle of the furnace charge opening. The auxiliary arm compresses the spring component as the furnace charge opening squeezes, adaptively adjusting the unfolded length of the main arm and auxiliary arm. The center of the sand mold opening is adjusted to match the parabolic landing point of the furnace charge opening, effectively reducing the molten material splashing and waste caused by contact between the molten material and the edge of the sand mold opening, thus avoiding safety hazards to surrounding processing personnel and the processing environment.

[0054] During the unloading stage, the cast sand mold is deflected close to the unloading conveyor frame 4 by axial rotation of the casting rotary table 1, completing the continuous running trajectory of single-mold sand mold casting; the platform splicing guide frame 2 is sleeved on the top of the central track groove 104, and several sets of guide rollers 201 are arranged at equal intervals between the outer walls of the top of the multiple sets of platform splicing guide frames 2. The middle of the platform splicing guide frame 2 is recessed with an adaptation slot that communicates with the central track groove 104. The inner wall of the adaptation slot is recessed with an inner guide groove 204. The inner wall of the inner guide groove 204 near the feeding conveyor frame 3 is provided with a limiting rack 203. The inner guide groove 204 is provided with a spring protrusion 202 near the limiting rack 203.

[0055] After a single sand mold is poured, the rotating shaft 101 drives the pouring rotary table 1 to rotate at a uniform speed. During the pouring of the current sand mold, the next sand mold has been adjusted and transferred to the next pouring fan plate 103, while the current sand mold is moved closer to the unloading conveyor 4. Before it is transferred to the unloading conveyor 4, the current sand mold and the next sand mold can be intermittently poured according to the pouring needs. The specific adjustments are made as needed. After the pouring is completed and the sand mold is transferred to the unloading conveyor 4, the poured sand mold is pushed and transferred to the unloading conveyor 4 by the cooperation of the platform splicing guide 2, the front grab hook 6 and the rear baffle 8. The unloading conveyor 4 then transports the sand mold to the heat preservation area, realizing the production line process of continuous automated feeding, precise pouring and automated unloading and transfer of molten electrofused bricks during the pouring and casting process.

[0056] Combining Embodiment 1 and Embodiment 2, the pre-positioning and adjustment of the next set of sand molds can be completed during the casting of one set of sand molds, which greatly shortens the sand mold replacement interval. Through the linkage control mechanism of the platform splicing guide 2, the front grab hook 6 and the rear baffle 8, the mismatch of the gate caused by the traditional sand mold placement offset, as well as the problem of the stage mismatch between the landing point of the molten material parabola and the sand mold gate during the pouring process, eliminates the waste and safety hazards of molten material splashing, and reduces the intensity of manual operation and environmental risks.

[0057] The continuous casting process system for electrofused bricks is composed of a limit adjustment mechanism and a pouring rotary table 1. In the feeding stage, a feeding control module is built based on the feeding conveyor frame 3 to regulate the sand mold transportation and feeding. In the regulation stage, a sand mold position calibration module is built based on the side adjustment frame 5 to assist in ensuring the sand mold's placement on the surface of the splicing guide frame 2 meets the molten material pouring requirements and to make adjustments. In the pouring stage, a pouring regulation module is built based on the splicing guide frame 2, the front grab hook 6, and the rear baffle 8 to adjust the sand mold's connection with the molten material based on the parabolic landing point of the molten material during the pouring process. In the unloading stage, an unloading control module is built based on the unloading conveyor frame 4 to coordinate the transportation and unloading of the poured sand mold.
