Description

Technical Field

[0001] This invention belongs to the field of mining centrifuge technology, and particularly relates to a centrifuge blade with a wear-resistant cladding process and its processing method. Background Technology

[0002] Screen settling centrifuges, with their core advantages of continuous operation, high separation efficiency, and large processing capacity, are widely used in many industrial fields such as coal washing, mineral sorting, chemical solid-liquid separation, and environmental sludge treatment. They are a core piece of equipment in solid-liquid two-phase separation processes. During operation, the centrifuge relies on the high-speed rotating cylinder to drive the spiral blades to continuously rotate, achieving material settling, classification, and conveying through a strong centrifugal force field. As the core working component that is in direct and continuous contact with high-hardness material particles and high-concentration slurry, the blades have long faced extremely severe problems of abrasive wear, high-speed impact, and slurry erosion.

[0003] Continuous blade wear not only directly damages the original blade profile accuracy, leading to decreased material conveying efficiency and deteriorated solid-liquid separation, making it impossible to consistently meet production process requirements, but also causes uneven clearance between the blades and the drum, resulting in increased equipment vibration and excessive noise. This further accelerates the damage to core components such as bearings and seals, significantly shortening the overall service life of the equipment. Furthermore, excessive blade wear necessitates frequent shutdowns for maintenance and replacement of spare parts, increasing both manpower and material costs for equipment maintenance. It can also cause unplanned shutdowns of continuous production lines, resulting in severe economic losses for the company.

[0004] Current conventional blade processing technologies in the industry are no longer sufficient to meet the requirements for long-term wear resistance of blades under complex operating conditions. They generally suffer from weak adhesion between the wear-resistant layer and the substrate, easy detachment, uneven hardness, and short wear life. At the same time, the blade curvature forming and welding installation processes suffer from defects such as insufficient forming accuracy, poor fit with the cylinder, and welding stress concentration, which further exacerbate the risk of blade failure. Therefore, it is urgent to develop a more complete integrated process of wear-resistant cladding and high-precision forming to systematically solve the above-mentioned industry pain points. Summary of the Invention

[0005] Based on the technical problems existing in the prior art, the present invention provides a centrifuge blade with wear-resistant cladding process and its processing method.

[0006] According to a first aspect of the technical solution of the present invention, a centrifuge blade with a wear-resistant cladding process is provided, comprising a blade steel plate, wherein a cladding layer is provided on the surface of the blade steel plate, the cladding layer comprising an end face cladding layer, a front face cladding layer and a back face cladding layer, wherein the thickness of the front face cladding layer is greater than the thickness of the end face cladding layer, and the thickness of the end face cladding layer is greater than the thickness of the back face cladding layer.

[0007] According to a second aspect of the technical solution of the present invention, a method for processing centrifuge blades using a wear-resistant cladding process is provided, which is used to prepare centrifuge blades using the aforementioned wear-resistant cladding process, and includes the following steps: Step S1: Fix the blade steel plate to the centrifuge cylinder by welding; Step S2: The blade steel plate is clad using cladding equipment and pre-prepared alloy powder to obtain clad blades; Step S3: Grinding and dynamic balancing are performed on the cladding blades to obtain centrifuge blades.

[0008] Preferably, the alloy powder comprises tungsten carbide and a binder phase metal, wherein the mass fraction of the tungsten carbide in the alloy powder is 70%.

[0009] Preferably, the particle size range of the alloy powder is 100μm to 300μm.

[0010] Preferably, the preparation of the alloy powder includes the following steps: Tungsten carbide and binder phase metal were mixed in a mass ratio of 7:3 to obtain a mixed powder. Sintering the mixed powder yields a cemented carbide blank; The cemented carbide blank was subjected to an electric arc micro-explosion to obtain alloy powder.

[0011] Preferably, the cladding equipment is a plasma cladding equipment or a laser cladding equipment.

[0012] Preferably, when using a plasma cladding device, image data of the molten pool in the plasma cladding device is acquired, and the operating parameters of the plasma cladding device are adjusted according to the image data.

[0013] Preferably, when using a laser cladding device, the internal structure data of the cladding layer during the cladding process is obtained by optical coherence tomography, and the operating parameters of the laser cladding device are adjusted according to the internal structure data.

[0014] Preferably, the cladding equipment uses argon as a protective gas.

[0015] Preferably, the grinding process involves a grinding speed of 20 m / s to 30 m / s, a feed rate of 0.02 mm / r to 0.05 mm / r, and a grinding depth of 0.1 mm to 0.2 mm.

[0016] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects: 1. This invention sets three cladding layers on the surface of the blade steel plate: the end face, the front face, and the back face. It adopts a differentiated design with the front cladding layer being thicker than the end face cladding layer and the end face cladding layer being thicker than the back face cladding layer. This makes the thickness of the cladding layer completely match the actual wear gradient of different working surfaces of the blade, achieving directional reinforcement protection in high wear areas. At the same time, it avoids material redundancy in low wear areas, solving the pain point of insufficient protection and cost waste of existing equal-thickness cladding layers, and significantly extending the service life of the blade.

[0017] 2. This invention employs a three-step core process: welding and fixing the blade steel plate to the cylinder, preparing a wear-resistant layer by alloy powder cladding, and grinding and dynamic balancing to calibrate accuracy. This enables the blade to achieve standardized preparation throughout the entire process, from structural assembly and wear protection to operational accuracy. It achieves the core effects of strong blade welding, excellent wear resistance, and stable operation, solving the problems of poor forming accuracy, insufficient wear resistance, and large vibration during centrifuge operation in existing processes, thus ensuring the separation efficiency and long-term stable operation of the centrifuge.

[0018] 3. This invention uses an alloy powder with a tungsten carbide mass fraction of 70% and a binder phase metal, so that the cladding layer can simultaneously take into account the ultra-high hardness brought by tungsten carbide and the excellent toughness provided by the binder phase metal. This achieves a balance between the wear resistance, impact resistance and crack resistance of the cladding layer, and solves the industry pain points of easy brittle fracture and detachment when the tungsten carbide content is too high and insufficient wear resistance when the content is too low. This significantly improves the wear protection effect of the blade.

[0019] 4. By using alloy powder with a particle size range of 100μm to 300μm, the present invention enables continuous and stable powder feeding during the cladding process and uniform and controllable flowability of the molten pool metal. This results in a cladding layer with high density, uniform thickness, and no defects such as pores and cracks. At the same time, it avoids the problems of fine powder agglomeration and clogging, and poor fusion of coarse powder. This ensures the consistency of the cladding layer forming quality with batch production and improves the yield of finished blades.

[0020] 5. This invention uses a three-step method of batching and mixing, sintering and blanking, and electric arc micro-explosion to prepare alloy powder, so that tungsten carbide particles are uniformly dispersed in the binder phase metal. This achieves high powder sphericity, good flowability, and excellent metallurgical bonding performance with the matrix during cladding. It solves the problems of uneven powder composition, easy detachment of cladding layer, and unstable wear resistance of conventional mechanically mixed powders. It ensures the wear resistance life and structural stability of the blade cladding layer from the raw material end.

[0021] 6. By using plasma cladding equipment or laser cladding equipment as the cladding processing carrier, the cladding process can be flexibly adapted and selected according to the blade deformation requirements, production efficiency, and processing cost. This achieves a high-strength metallurgical bond between the cladding layer and the blade steel plate substrate, taking into account the cladding quality, production efficiency, and customized processing needs under different working conditions, thereby improving the applicability and processing flexibility of the process.

[0022] 7. This invention acquires image data of the molten pool during the plasma cladding process and adjusts the equipment operating parameters in real time based on the image data, making the shape, size and stability of the molten pool controllable throughout the process. This achieves uniform composition of the cladding layer without forming defects, avoids cladding quality fluctuations caused by the lag of manual adjustment, solves the problems of the inability to monitor the existing plasma cladding process in real time and poor consistency of batch products, and ensures the stable quality of the blade cladding layer.

[0023] 8. This invention uses optical coherence tomography to obtain internal structural data of the cladding layer during the laser cladding process, and adjusts the equipment operating parameters in real time based on the data. This allows for the real-time identification and correction of defects such as pores and cracks inside the cladding layer, resulting in excellent cladding layer density and minimal processing deformation. This solves the problems of existing laser cladding processes, such as the inability to monitor internal defects online and low finished product qualification rate, while also significantly reducing the cost of deformation correction after blade cladding.

[0024] 9. By using argon as the protective gas for the cladding equipment, the high-temperature molten pool area is completely isolated from the outside air, achieving no oxidation or nitriding between the alloy powder and the base metal during the cladding process. This avoids defects such as oxidation inclusions, increased brittleness, and decreased bonding strength in the cladding layer, significantly improving the bonding strength and structural stability between the cladding layer and the blade steel plate substrate, and extending the effective protective life of the cladding layer.

[0025] 10. This invention, by employing a grinding speed of 20m / s to 30m / s, a feed rate of 0.02mm / r to 0.05mm / r, and a single grinding depth of 0.1mm to 0.2mm during the grinding process, ensures that the outer diameter of the blade is free from edge chipping and cracking of the cladding layer during grinding. It achieves precise control of the clearance between the blade and the drum, solves the problems of cladding layer damage and dimensional inaccuracies caused by improper grinding parameters, and ensures the long-term stable separation accuracy and operational safety of the centrifuge.

[0028] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0029] This invention discloses a centrifuge blade with a wear-resistant cladding process and its processing method, belonging to the field of mining centrifuge technology. The centrifuge blade includes a blade steel plate, and the surface of the blade steel plate is provided with a cladding layer. The cladding layer includes an end face cladding layer, a front face cladding layer, and a back face cladding layer. The thickness of the front face cladding layer is greater than the thickness of the end face cladding layer, and the thickness of the end face cladding layer is greater than the thickness of the back face cladding layer. This invention, by setting three cladding layers on the surface of the blade steel plate (end face, front face, and back face) and adopting a differentiated design with the front face cladding layer being thicker than the end face cladding layer and the end face cladding layer being thicker than the back face cladding layer, ensures that the cladding layer thickness perfectly matches the actual wear gradient of different working surfaces of the blade. This invention achieves targeted reinforcement protection in high-wear areas while avoiding material redundancy in low-wear areas, solving the pain points of insufficient protection and cost waste associated with existing uniform-thickness cladding layers, and significantly extending the service life of the blade.

[0030] The following description, in conjunction with the accompanying drawings and specific embodiments, illustrates the centrifuge blades and their processing method using the wear-resistant cladding process of the present invention. Example

[0031] like Figure 1The centrifuge blade shown is a wear-resistant cladding process, comprising a blade steel plate 4. The surface of the blade steel plate 4 is provided with a cladding layer, which includes an end-face cladding layer 1, a front cladding layer 2, and a back cladding layer 3. The thickness of the front cladding layer 2 is greater than the thickness of the end-face cladding layer 1, and the thickness of the end-face cladding layer 1 is greater than the thickness of the back cladding layer 3. The blade steel plate 4 serves as the structural load-bearing substrate of the entire blade, providing a stable and highly adhesive foundation for the cladding layer. It also undertakes torque transmission and material conveying functions during centrifuge operation, ensuring the overall structural rigidity, impact resistance, and installation adaptability of the blade. The structural foundation for the blade's long-term stable operation is achieved through a continuous and dense wear-resistant protective barrier formed by the cladding layer on the surface of the blade steel plate 4. This barrier isolates the substrate from direct abrasive cutting, high-speed scouring, and media corrosion caused by materials during centrifuge operation, fundamentally addressing the core pain points of existing centrifuge blades, such as easy wear and short service life. The cladding layer 2, covering the front surface of the blade facing the material during operation, is the most severely worn part of the blade, directly bearing the continuous high-speed impact, abrasive extrusion cutting, and strong scouring wear of the material to be separated. The maximum thickness provides targeted high-strength wear-resistant protection for the most wear-prone areas of the blade, completely solving the problems of traditional centrifuge blades. The problem of rapid wear and failure of the blade's feed-facing surface is addressed by significantly extending the blade's continuous working cycle and reducing the frequency and cost of equipment downtime due to blade wear. The end-face cladding layer 1, covering the outer edge of the blade, forms a precise clearance fit with the centrifuge drum. During operation, it withstands both radial scouring wear from the material and slight scraping friction caused by clearance fluctuations. The wear intensity is second only to the feed-facing surface, and the thickness setting ensures the long-term stability of the blade's outer diameter, precisely maintaining the designed fit clearance between the blade and the drum. This prevents the fit clearance from widening due to end-face wear, ensuring long-term stable material separation accuracy and efficiency of the centrifuge. Meanwhile, to eliminate the equipment safety risks caused by excessive wear on the end face, such as scraping and collision between the blade and the drum, the back cladding layer 3 covering the working surface of the blade back material only bears the backflow scouring and slight wear of the material during operation. The wear intensity is the lowest on the entire working surface. The minimum thickness setting can provide basic wear-resistant and corrosion-resistant protection for the blade back material surface, avoiding backflow wear and local corrosion failure of the substrate. At the same time, the differentiated thin and thin thickness design can effectively control the heat input during the cladding process, greatly reducing the thermal deformation during blade welding and cladding, taking into account both the protective effect and the blade forming accuracy, and avoiding the material waste and increased process cost caused by thick cladding in the whole area.

[0032] Specifically, the blade steel plate is made of wear-resistant steel. The dimensions are designed according to the working parameters and operating conditions of the centrifuge. Then, the wear-resistant steel substrate is cut using a CNC cutting machine according to the dimensional design to obtain the blade steel plate 4. The length tolerance of the blade steel plate 4 is controlled within ±0.5mm, and the width tolerance is controlled within ±0.3mm.

[0033] Specifically, before cladding, the blade steel plate is first pressed to its designed curvature using a hydraulic forming machine and a special mold. A hydraulic forming machine of appropriate tonnage is selected, and a special mold matching the designed curvature is installed. Before pressing, the hydraulic forming machine is calibrated for precision, including pressure sensor calibration (error controlled within ±1%) and mold installation position calibration (horizontal and verticality errors controlled within ±0.02mm / m). During pressing, the cut blade steel plate 4 is placed in the mold, and the hydraulic forming machine is started, applying pressure at a uniform speed (pressing speed set to 510mm / s~10mm / s) to gradually deform the blade steel plate 4 to the designed curvature. During the pressing process, the deformation of the blade steel plate 4 is monitored in real time using a displacement sensor to ensure that the curvature radius tolerance is controlled within ±0.2mm. Simultaneously, multiple sets of pressure sensors are used to monitor the pressure distribution, ensuring uniform stress on all parts of the blade steel plate 4 and preventing excessive local deformation. Example

[0034] This embodiment provides a method for processing centrifuge blades using a wear-resistant cladding process, which is used to prepare centrifuge blades using the wear-resistant cladding process described in Embodiment 1, and includes the following steps: Step S1: Fix the blade steel plate 4 to the centrifuge cylinder by welding; Step S2: The blade steel plate 4 is clad using cladding equipment and pre-prepared alloy powder to obtain a clad blade; Step S3: Grinding and dynamic balancing are performed on the cladding blades to obtain centrifuge blades.

[0035] Specifically, in step S1, the welded area between the pressed, curved blade steel plate 4 and the centrifuge cylinder is first pre-cleaned. This pre-cleaning includes degreasing and cleaning the welded area with an organic solvent (e.g., acetone) to remove oil and impurities. Then, mechanical grinding (using 80-120 mesh sandpaper) is used to remove the oxide layer, giving the welded surface a metallic luster. Afterward, a special welding flux is applied to the welded area to improve the weld quality.

[0036] Specifically, in step S1, the welding is performed using gas shielded arc welding. The welding current is set according to the thickness and material of the blade steel plate 4. The welding current is generally 150A~200A, the welding voltage is 20V~25V, the welding speed is 4mm / s~6mm / s, and the shielding gas flow rate is 12L / min~18L / min.

[0037] Specifically, the alloy powder comprises tungsten carbide and a binder phase metal, wherein the tungsten carbide has a mass fraction of 70% in the alloy powder. The binder phase metal includes, but is not limited to, any one or more combinations of materials such as cobalt or nickel. The particle size range of the alloy powder is 100 μm to 300 μm.

[0038] Specifically, the preparation of the alloy powder includes the following steps: Tungsten carbide and binder phase metal were mixed in a mass ratio of 7:3 to obtain a mixed powder. Sintering the mixed powder yields a cemented carbide blank; The cemented carbide blank was subjected to an electric arc micro-explosion to obtain alloy powder.

[0039] Specifically, the alloy powder formed by the electric arc micro-explosion needs to be placed in a drying oven for drying treatment. The drying temperature in the drying oven is set to 120℃~150℃, and the drying time is 2h~3h, so as to ensure that the mass fraction of moisture content in the alloy powder is less than 0.05% and prevent defects such as pores from being generated during the cladding process.

[0040] Specifically, the cladding equipment is a plasma cladding equipment or a laser cladding equipment.

[0041] Specifically, when using a plasma cladding device, image data of the molten pool in the plasma cladding device is acquired, and the operating parameters of the plasma cladding device are adjusted based on the image data.

[0042] Specifically, when using plasma cladding equipment, the spiral cylinder (i.e., the integral part after welding the centrifuge cylinder and the blade steel plate 4) is installed on a dedicated CNC plasma cladding equipment workbench with multi-axis linkage function. The plasma cladding gun is calibrated to ensure that the perpendicularity deviation between the plasma cladding gun and the surface of the blade steel plate 4 is within ±0.5°. The plasma cladding parameters are set as follows: plasma current 200A~220A (adjusted according to the size of the blade steel plate 4 and the cladding thickness), voltage 28V~32V, working gas (argon) flow rate 15L / min~20L / min, powder feeding gas (argon) flow rate 3L / min~5L / min, powder feeding speed 8g / min~12g / min, cladding speed 5mm / s~8mm / s, and cladding layer thickness controlled at 1mm~3mm. During the plasma cladding process, a high-speed camera (frame rate not less than 1000fps) is used to monitor the molten pool and plasma arc in real time. The shape, size, and stability of the molten pool are monitored by image analysis algorithms. When the molten pool fluctuates by more than ±10%, the operating parameters of the plasma cladding equipment are automatically adjusted to ensure the uniformity of composition and the stability of quality of the cladding layer.

[0043] Specifically, when using laser cladding equipment, the internal structure data of the cladding layer during the cladding process is obtained by optical coherence tomography, and the operating parameters of the laser cladding equipment are adjusted according to the internal structure data.

[0044] Specifically, the laser cladding equipment is suitable for working conditions with special requirements on deformation. When using laser cladding equipment, a high-power fiber laser (6000W) is used. The distance between the laser cladding head and the blade surface is adjusted to 15mm~20mm, the spot diameter, and the scanning speed are determined according to specific conditions. The laser power is 4800W~6000W (adjusted according to the thickness and quality requirements of the cladding layer). A coaxial powder feeding method is adopted, and the powder feeding speed and the flow rate of the protective gas (argon) are determined according to specific conditions. During the laser cladding process, the internal structure and defects of the cladding layer are monitored in real time through optical coherence tomography. When defects such as pores and cracks are detected inside the cladding layer, the laser power, scanning speed, and powder feeding speed are automatically adjusted. At the same time, the movement trajectory of the laser cladding head is adjusted through a feedback control system to locally repair the defective areas, ensuring the density and quality of the cladding layer.

[0045] Specifically, the cladding equipment uses argon as a protective gas.

[0046] Specifically, the grinding process involves mounting the clad centrifuge cylinder onto a high-precision CNC grinding machine, using a specialized fixture to position and clamp the cylinder, ensuring the installation eccentricity is within ±0.02mm. Then, a suitable grinding wheel (such as a diamond wheel with a grit size of 100-150 mesh) is selected. The grinding amount and precision are determined based on the design clearance requirements between the blade steel plate 4 and the drum. The grinding speed is 20m / s-30m / s, the feed rate is 0.02mm / r-0.05mm / r, and the grinding depth is 0.1mm-0.2mm. During the grinding process, a coordinate measuring system is used to measure the outer diameter and roundness of the blade steel plate 4 in real time. The CNC system automatically compensates for grinding errors, ensuring the clearance tolerance between the blade and the drum is controlled within 0.75mm.

[0047] Specifically, the dynamic balancing process involves mounting the spiral drum on a dynamic balancing machine and performing testing and adjustment according to the requirements of dynamic balancing grade G6.3. By adding or removing counterweights (the counterweight material can be selected based on the centrifuge structure and actual conditions, such as metal blocks) at appropriate locations within the centrifuge, the imbalance during centrifuge operation is controlled within a specified range. During the dynamic balancing test, the rotational speed of the dynamic balancing machine is determined based on the centrifuge's rated speed and the machine's performance, generally 80% to 100% of the centrifuge's rated speed, ensuring that the test results accurately reflect the centrifuge's balance under actual operating conditions.
