Description

Technical Field

[0001] This invention relates to the field of aluminum coil production technology, and more specifically to an online alloy addition device for aluminum coil production. Background Technology

[0002] In the continuous casting and rolling process of aluminum coils, molten aluminum undergoes multiple processes including melting, purification, casting, and cold rolling before finally being rolled into aluminum strip coils. To optimize the mechanical and processing properties of aluminum, alloying elements are typically added to the molten aluminum, among which aluminum-titanium-boron (Al-Ti-B) alloy is one of the most commonly used grain refiners. The addition of this alloy can significantly refine the grain structure of aluminum, improve the strength, plasticity, and surface quality of the aluminum coil, and effectively prevent defects such as edge cracking and surface roughness from occurring during subsequent rolling or annealing processes.

[0003] Currently, the addition of Al-Ti-B alloys is typically completed during the process of conveying molten aluminum to the casting and rolling mill. Specifically, after flowing from the melting furnace, the molten aluminum enters the casting and rolling mill via a runner or conveying pipe. At a certain point in the conveying channel, an alloy addition device adds Al-Ti-B alloy (usually in filament or granular form) into the molten aluminum, dissolving and uniformly distributing it. However, existing alloy addition devices have the following problems in practical applications:

[0004] 1. Unable to dynamically adapt to changes in molten aluminum flow rate;

[0005] The flow rate of molten aluminum is determined by both the flow velocity and the unit cross-sectional area. In actual production, the flow velocity of molten aluminum may vary due to factors such as melting temperature, casting speed, and the angle of the flow channel.

[0006] Most existing alloy addition devices use a fixed addition rate, which cannot adjust the amount of alloy added according to the real-time changes in the aluminum melt flow rate, resulting in unstable alloy addition ratios. If the aluminum melt flow rate increases but the amount of alloy added is insufficient, the grain refinement effect will decrease, and the aluminum coil will be prone to edge breakage; conversely, if the aluminum melt flow rate decreases but the amount of alloy added is excessive, it may cause resource waste and even affect the purity of the aluminum melt.

[0007] 2. The alloy is not mixed evenly;

[0008] Because the flow of molten aluminum in the conveying channel may contain turbulence or dead zones, traditional alloying methods cannot ensure that the alloy dissolves quickly and uniformly in the molten aluminum, which can easily lead to local enrichment or unmelted particles, affecting the uniformity of the final aluminum coil structure.

[0009] Therefore, an online alloy addition device for aluminum coil production is needed to overcome the above-mentioned problems. Summary of the Invention

[0010] To address the aforementioned problems, embodiments of the present invention provide an online alloy addition device for aluminum coil production, thereby achieving the objective of resolving the problems mentioned in the background art.

[0011] To achieve the above objectives, the present invention employs the following technical solution: an online alloy addition device for aluminum coil production, comprising a conveying channel for conveying molten aluminum; the conveying channel is sequentially arranged along the flow direction of the molten aluminum as follows: a feeding section for feeding strip-shaped alloy into the conveying channel, so that the strip-shaped alloy melts inside the molten aluminum; a bearing section for bearing the alloy coil; and a conveying section for conveying the strip-shaped alloy from the alloy coil to the feeding section; the conveying section is designed such that the conveying speed of the strip-shaped alloy can be adjusted in real time according to the flow rate of the molten aluminum inside the conveying channel.

[0012] As a further improvement to the above technical solution:

[0013] The conveying unit includes: a housing, which covers the top of the conveying channel and communicates with the conveying channel internally; an impeller, which is disposed inside the housing and rotates by the flow power of molten aluminum; a clamping assembly, which is disposed on the top of the housing and clamps and drives the strip alloy to move; and a driving assembly, which transmits the rotational power of the impeller to the clamping assembly to drive the clamping assembly to operate.

[0014] The conveying unit further includes an adjustment component, which adjusts the height of the impeller according to the liquid level of the aluminum liquid inside the conveying channel, and at the same time cooperates with the drive component to adjust the moving speed of the clamping component driving the strip alloy.

[0015] The clamping assembly includes: a frame, mounted on the top of the housing; a roller, rotatably disposed inside the frame, which, when rotated, can drive the strip-shaped alloy clamped inside to move; and an input shaft, disposed on the roller, for power input to the roller.

[0016] The adjustment assembly includes: a chute, located on the side of the housing for the movement of impeller one; an electric push rod, mounted on the conveying channel, wherein impeller one is rotatably mounted in a support ring at the end of its piston rod, and the piston rod moves to drive impeller one to move; a baffle, rotatably mounted on the shaft of impeller one for closing the chute; and a liquid level detection mechanism, mounted on the conveying channel for monitoring the liquid level of aluminum liquid inside the conveying channel.

[0017] The drive assembly includes: a drive wheel fixedly connected to the shaft of impeller one; a rotating shaft rotatably mounted on a baffle plate; a driven wheel fixedly connected at the bottom end to mesh with the drive wheel; a variable diameter wheel fixedly connected at the top end; and a transmission wheel fixedly connected to the end of the input shaft, wherein the transmission wheel abuts against the variable diameter wheel through the elastic support of the input shaft.

[0018] The input shaft includes: a first connecting shaft, a connecting roller, a second connecting shaft slidably disposed inside the first connecting shaft, and a spring disposed between the first connecting shaft and the second connecting shaft.

[0019] The bearing unit includes: a housing, which covers the top of the conveying channel and is internally connected to the conveying channel; an impeller II, which is disposed inside the housing and rotates by the flow power of the aluminum liquid; and a drive roller, which is rotatably disposed on the impeller II by a one-way bearing to assist the rotation of the alloy coil.

[0020] The feeding section includes a feeding pipe installed on the conveying channel.

[0021] The beneficial effects of the embodiments of the present invention are as follows:

[0022] The alloy coil is fixed to the support unit, and the strip alloy is guided to the feeding unit via the conveying unit. The feeding unit uses a heat-insulating feed pipe made of high-temperature resistant material to ensure that the strip alloy accurately enters the high-temperature molten aluminum in the conveying channel. When the flow rate of molten aluminum increases, the conveying unit automatically increases the alloy conveying speed; conversely, it decreases the conveying speed accordingly, thereby always maintaining the optimal ratio of alloy elements to molten aluminum. The conveying unit can automatically adjust the conveying speed of the strip alloy according to the real-time changes in the flow rate of molten aluminum inside the conveying channel, achieving precise matching between the alloy addition amount and the flow rate of molten aluminum.

[0023] The conveying unit can utilize the kinetic energy of the aluminum liquid flow as a driving source, eliminating the need for additional power equipment and achieving energy-saving and environmentally friendly alloy conveying. Secondly, the rotation speed of impeller one is directly proportional to the flow speed of the aluminum liquid. Through the organic combination of fluid mechanics and mechanical transmission, the alloy conveying speed and the aluminum liquid flow rate are automatically kept synchronized, ensuring the stability of the alloy addition ratio.

[0024] By adjusting the height of the impeller, the working depth of the impeller is dynamically matched with the level of the molten aluminum, thus ensuring the stability of the hydraulic drive force.

[0025] The regulating component achieves coordinated control of the impeller's working depth and the alloy conveying speed through a liquid level linkage mechanism. When the liquid level detection mechanism detects a rise in the aluminum liquid level in the conveying channel, the electric push rod drives the impeller to move upward along the chute. This displacement is synchronously transmitted to the variable diameter wheel through a rigidly connected rotating shaft, causing it to produce a corresponding vertical displacement. Since the drive wheel maintains a constant clamping force with the variable diameter wheel through elastic support, the rise of the variable diameter wheel causes the contact point between the two to move towards the large diameter end of the variable diameter wheel, thereby increasing the rotational speed of the drive wheel. The change in rotational speed is transmitted to the clamping component through the input shaft, causing a corresponding increase in the rotational speed of the roller, ultimately increasing the conveying speed of the strip alloy.

[0026] This embodiment constructs a three-stage alloy homogenization system by optimizing the spatial layout and functional coordination of each component. Specifically, the feeding section, conveying section, and bearing section are arranged sequentially along the aluminum melt flow direction according to the process sequence. The feeding section adopts an inclined guide nozzle design, injecting strip-shaped alloys at an incident angle of 15-30°, utilizing the shear force of the aluminum melt to promote rapid melting. The mixed aluminum melt first flows through impeller one of the conveying section, where impeller one generates a dual effect of axial flow splitting and radial swirling of the aluminum melt, achieving primary mixing. Subsequently, the aluminum melt enters the bearing section's working area, where it is further mixed by impeller two, ensuring uniform mixing of the alloy within the aluminum melt.

[0043] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0044] See Figure 1-9 This invention discloses an online alloy addition device for aluminum coil production, comprising a conveying channel 1, a feeding section 2, a supporting section 3, and a conveying section 4. The conveying channel 1 is used for continuous conveying of molten aluminum, and the feeding section 2, supporting section 3, and conveying section 4 are arranged sequentially along the flow direction of the molten aluminum. The feeding section 2 is used to precisely feed the strip-shaped alloy into the conveying channel 1, allowing the strip-shaped alloy to fully melt in the high-temperature molten aluminum. The supporting section 3 is used to stably support the alloy coil, ensuring a continuous supply of strip-shaped alloy. The conveying section 4 is responsible for conveying the strip-shaped alloy from the alloy coil to the feeding section 2. Specifically, the conveying section 4 in this embodiment adopts an adjustable design, which can automatically adjust the conveying speed of the strip-shaped alloy according to the real-time changes in the flow rate of the molten aluminum inside the conveying channel 1, achieving precise matching between the alloy addition amount and the molten aluminum flow rate.

[0045] The specific working process of the device is as follows: First, the alloy coil is fixed on the bearing part 3, and the strip alloy is guided to the feeding part 2 via the conveying part 4. The feeding part 2 is a feeding pipe made of high-temperature resistant material with heat insulation effect to ensure that the strip alloy accurately enters the high-temperature aluminum liquid in the conveying channel 1. When the flow rate of aluminum liquid increases, the conveying part 4 automatically increases the alloy conveying speed; conversely, it reduces the conveying speed accordingly, thereby always maintaining the optimal ratio of alloy elements to aluminum liquid.

[0046] See Figure 3-5 The illustration shows an embodiment of a conveying unit 4, which includes a housing 41, an impeller 42, a clamping assembly 43, and a drive assembly 44. The housing 41 is entirely covered on top of the conveying channel 1, and its lower part communicates with the interior of the conveying channel 1. An impeller 42 is disposed in the internal cavity of the housing 41. The impeller 42 is rotatably mounted inside the housing 41, and its blades extend into the aluminum liquid flow channel. When the aluminum liquid flows, the hydrodynamic force generated directly acts on the blades of the impeller 42, driving the impeller 42 to rotate.

[0047] The clamping assembly 43 is installed at the top of the housing 41 and adopts a roller clamping structure to ensure a stable clamping and conveying force for the strip alloy. The drive assembly 44, as a power transmission mechanism, transmits the rotational power of the impeller 42 to the clamping assembly 43 through a power transmission system, causing the roller clamping structure to rotate synchronously. Firstly, the conveying unit 4 can utilize the kinetic energy of the flowing aluminum liquid as a drive source, eliminating the need for an additional power unit and achieving energy-saving and environmentally friendly alloy conveying. Secondly, the rotational speed of the impeller 42 is directly proportional to the flow rate of the aluminum liquid. Through the organic combination of fluid mechanics and mechanical transmission, the alloy conveying speed and the aluminum liquid flow rate automatically maintain synchronous changes, ensuring the stability of the alloy addition ratio.

[0048] See Figure 3 The illustration shows an embodiment of the clamping assembly 43, which includes a frame 431, rollers 432, and an input shaft 433. The frame 431 is fixedly mounted on the top of the housing 41, forming a stable support frame. The rollers 432 are rotatably disposed inside the frame 431, and their unique inverted triangular arrangement consists of three clamping rollers with different functions: the bottom active clamping roller is directly connected to the input shaft 433, and the side of this clamping roller is machined with equally spaced protrusions, which achieve precise conveying through the friction between the protrusions and the surface of the strip alloy; the upper two symmetrically arranged driven clamping rollers have grooves on their surfaces, the groove width of which is larger than the diameter of the strip alloy, forming a flexible limiting space that allows the strip alloy to swing slightly.

[0049] The working principle of the clamping assembly 43 is as follows: the input shaft 433 receives rotational power from the drive assembly 44, driving the bottom active clamping roller to rotate, and pushing the strip alloy forward through the protruding structure; at the same time, the V-shaped grooves of the two upper driven clamping rollers provide guidance and limiting functions for the strip alloy, which can effectively constrain the conveying trajectory of the alloy strip and allow it to swing within a certain range. This special design cleverly solves the swaying problem generated when the strip alloy is released from the coil. The flexible limiting function of the groove absorbs the swaying energy, avoiding jamming or deviation of the alloy strip during the conveying process, and ensuring the smoothness and reliability of the conveying process. The roller body 432 proposed in this application adopts an inverted triangular three-roller layout, combined with the complementary design of protrusions and grooves, to achieve the dual functions of precise conveying and sway compensation of the strip alloy; and the protruding structure of the active clamping roller enhances the contact friction with the alloy strip, preventing slippage; the groove design of the driven clamping roller ensures both guiding accuracy and provides the necessary sway margin, effectively solving the swaying problem when the alloy coil is unwound.

[0050] See Figure 2 , Figure 4This illustrates another embodiment of the conveying unit 4. The clamping assembly 43 further includes an adjusting assembly 45, which automatically adjusts the depth of the impeller 42 immersed in the molten aluminum according to the molten aluminum level and automatically adjusts the alloy conveying speed. The adjusting assembly 45 includes a chute 451, an electric push rod 452, a baffle 453, and a liquid level detection mechanism. The chute 451 is longitudinally formed on the side of the housing 41, providing a stable lifting guide channel for the impeller 42. The electric push rod 452 is fixed to the outer wall of the conveying channel 1 by a high-strength bracket. Its piston rod end is provided with a support ring made of high-temperature resistant alloy. The shaft of the impeller 42 is rotatably mounted in the support ring to ensure that the impeller 42 can still rotate smoothly during the lifting process.

[0051] Baffle 453 is rotatably mounted on the shaft of impeller 42, and is made of high-temperature resistant stainless steel. Its dimensions match the cross-section of chute 451. When impeller 42 rises or falls, baffle 453 rotates with the shaft and always fits against the inner wall of chute 451, forming a dynamic sealing structure that effectively prevents heat loss from the molten aluminum. The liquid level detection mechanism uses a non-contact laser rangefinder sensor, installed in the conveying channel 1 near the outer casing 41 (not shown in the figure), to monitor changes in the molten aluminum level in real time.

[0052] The operating procedure of the regulating component 45 is as follows: the liquid level detection mechanism collects the aluminum liquid height signal in real time. When the liquid level rises above the set threshold, the control system activates the electric push rod 452 to extend the piston rod, driving the impeller 42 to move upward along the slide 451, reducing the immersion depth of the impeller 42; simultaneously, the drive component 44 increases the conveying speed of the clamping component 43 to maintain a constant alloy addition ratio. Conversely, when the liquid level drops, the electric push rod 452 retracts, causing the impeller 42 to move downward, and the drive component 44 reduces the alloy conveying speed. The baffle 453 remains sealed throughout the entire regulating process.

[0053] The rotational speed of impeller 42 has a non-linear relationship with the force exerted by the molten aluminum, specifically as follows:

[0054] When the impeller 42 is immersed to an excessive depth, the fluid resistance torque on the impeller 42 increases significantly, resulting in a decrease in rotational speed. At this time, the position of the impeller is raised by the electric push rod 452 to reduce the immersion depth to the optimal range (usually 30-50% of the impeller diameter).

[0055] When the immersion depth is insufficient, the impeller 42 will not be powered enough, resulting in a low rotation speed. The system will automatically increase the immersion depth (by moving the electric push rod 452 downward) to enhance the driving force. That is, by adjusting the height of the impeller 42 through the adjustment component 45, the working depth of the impeller 42 is dynamically matched with the level of the molten aluminum, ensuring the stability of the hydraulic driving force.

[0056] See Figure 2The illustration shows an embodiment of the drive assembly 44, which includes a drive wheel 441, a rotating shaft 442, a driven wheel 443, a variable diameter wheel 444, and a transmission wheel 445. The drive wheel 441 is fixedly mounted on the upper end of the shaft of the impeller 42 via a key connection and rotates synchronously with the impeller 42. The rotating shaft 442 is mounted on a baffle 453, and its bottom end is fixedly connected to the driven wheel 443, which forms a precisely meshing gear pair with the drive wheel 441. The variable diameter wheel 444 is mounted on the top end of the rotating shaft 442. The variable diameter wheel adopts a conical structure design, and its working surface is a conical surface of 15-30 degrees. The transmission wheel 445 is connected to the input shaft 433 and maintains a constant contact pressure with the variable diameter wheel 444 under the action of the spring preload of the input shaft 433, forming a continuously variable friction transmission pair.

[0057] During operation, the rotational power of impeller 42 is transmitted to the rotating shaft 442 through the driving wheel 441 and the driven wheel 443 in sequence. The input shaft 433 is finally driven to rotate through the friction transmission between the variable diameter wheel 444 and the transmission wheel 445. The final output speed can be changed by adjusting the contact radius between the variable diameter wheel 444 and the transmission wheel 445, so as to achieve precise control of the alloy conveying speed.

[0058] The regulating component 45 achieves coordinated control of the working depth of impeller 42 and the alloy conveying speed through a liquid level linkage mechanism. When the liquid level detection mechanism detects a rise in the aluminum liquid level in the conveying channel 1, the electric push rod 452 drives impeller 42 to move upward along the slide 451. This displacement is synchronously transmitted to the variable diameter wheel 444 through the rigidly connected rotating shaft 442, causing it to generate a corresponding displacement in the vertical direction. Since the transmission wheel 445 maintains a constant clamping force with the variable diameter wheel 444 through elastic support, the rise of the variable diameter wheel 444 causes the contact point between the two to move towards the large diameter end of the variable diameter wheel 444. According to the speed relationship of conical friction transmission, V2 = V1 * (R2 / R1) (where V1 is the input speed, R1 is the contact radius of the variable diameter wheel, V2 is the output speed, and R2 is the radius of the transmission wheel 445), the speed of the transmission wheel 445 increases accordingly. The change in speed is transmitted to the clamping component 43 through the input shaft 433, causing the rotational speed of the roller 432 to increase accordingly, ultimately increasing the conveying speed of the strip alloy. This adjustment process forms a closed-loop control: liquid level rises → impeller moves upward → contact radius ratio increases → drive wheel speeds up → alloy delivery accelerates, ensuring that the alloy addition amount and aluminum liquid flow rate remain at the optimal ratio per unit time. In particular, the cone angle of the variable diameter wheel 444 has been optimized, so that the transmission ratio changes linearly when the impeller 42 rises and falls within the set range, ensuring control accuracy.

[0059] The input shaft 433 adopts an elastic telescopic structure design, specifically including connecting shaft one 4331, connecting shaft two 4332, and spring 4333. Connecting shaft one 4331 is fixedly connected to roller body 432 through a keyway fit, and has a precision guide hole machined inside; connecting shaft two 4332 is installed in the guide hole of connecting shaft one 4331 through a spline sliding fit, and the two form a kinematic pair that can slide relative to each other axially and rotate synchronously in the circumference; spring 4333 is made of high-temperature alloy material, pre-compressed and installed between the two connecting shafts, providing a constant axial thrust. The elastic connection design of the input shaft 433 automatically compensates for the axial displacement deviation of the variable diameter wheel 444 and the transmission wheel 445 during the adjustment process, ensuring that the friction transmission pair maintains contact pressure.

[0060] During operation, when the adjusting component 45 drives the variable diameter wheel 444 to rise and fall, the connecting shaft 4332 generates axial displacement under the drive of the transmission wheel 445. The extension and contraction deformation of the spring 4333 automatically absorbs this displacement, so that the transmission system is always in the optimal working state.

[0061] See Figure 4 The illustration shows an embodiment of the carrier section 3, which employs a hydraulically assisted unwinding mechanism, including a housing 31, an impeller 32, and a drive roller 33. The housing 31 is mounted on top of the conveying channel 1; the impeller 32 is rotatably mounted inside the housing 31; the drive roller 33 is mounted on the output shaft of the impeller 32 via a one-way overrunning clutch (one-way bearing), and the roller surface is covered with a high-friction coefficient ceramic layer. By setting the impeller 32 to utilize the flow energy of the molten aluminum to achieve auxiliary drive of the alloy coil, the traction load of the clamping assembly 43 is reduced; at the same time, the one-way transmission design allows the system to automatically adapt to different working conditions. When the conveying speed of the clamping assembly 43 is normal, the impeller 32 pushes the alloy coil to rotate through the drive roller 33; when the clamping speed increases and causes the rotation speed of the alloy coil to exceed that of the drive roller 33, the one-way bearing disengages to avoid generating reverse resistance.

[0062] This embodiment constructs a three-stage alloy homogenization system by optimizing the spatial layout and functional coordination of each component. Specifically, the feeding section 2, conveying section 4, and bearing section 3 are arranged sequentially along the aluminum liquid flow direction according to the process order. The feeding section 2 adopts an inclined guide nozzle design, injecting strip-shaped alloys at an incident angle of 15-30°, utilizing the shear force of the aluminum liquid to promote rapid melting. The mixed aluminum liquid first flows through impeller 42 of conveying section 4, where impeller 42 exerts a dual effect of axial diversion and radial swirling on the aluminum liquid, achieving primary mixing. Subsequently, the aluminum liquid enters the working area of ​​bearing section 3, where it is further mixed by impeller 32, ensuring uniform mixing of the alloy within the aluminum liquid.
