Description

Technical Field

[0001] This utility model relates to the field of coking equipment technology, and more specifically, to a high-coverage, anti-adhesion ceramic liner configuration. Background Technology

[0002] In the coking process, the coke oven is a crucial core piece of equipment. The working environment in the upper oxidation zone of the coke oven is extremely harsh, constantly subjected to the impact of falling high-temperature coke. This special operating condition places extremely high demands on the performance of the lining plates used in this area. Currently, traditional lining plates are commonly used in the upper oxidation zone of coke ovens. However, traditional lining plates have revealed many serious problems in actual use. On the one hand, coke easily adheres to the surface of traditional lining plates. When high-temperature coke impacts the lining surface, coke gradually adheres to the surface, forming a deposit over time. The appearance of this deposit layer seriously affects the normal operation of the coke oven. Because the thermal conductivity of the deposit layer differs from that of the lining plate itself, it leads to a significant decrease in heat transfer efficiency. The reduced heat transfer efficiency results in uneven temperature distribution within the coke oven, causing an imbalance in oven temperature control. Under these circumstances, localized overheating of the lining plate can occur due to the inability to dissipate heat in time, ultimately leading to lining plate deformation.

[0003] On the other hand, traditional liner plates have poor impact resistance. Related tests show that under the impact of a 3m high coke drop, the indentation depth of the traditional liner plate substrate reaches 3.5mm, indicating that traditional liner plates cannot effectively resist the impact force of falling coke and are prone to significant deformation. Simultaneously, traditional liner plates have low compressive strength and a high deformation rate. After long-term exposure to coke impact and high temperatures, their structural strength will rapidly decline, requiring frequent liner plate replacements, increasing production costs and maintenance workload.

[0046] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0048] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0049] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0050] Example 1:

[0051] like Figures 1-5As shown, a high-coverage, anti-adhesion ceramic liner configuration includes: a liner body 1 and a plurality of hexagonal prisms 2 embedded in a plurality of hexagonal holes in the liner body 1; the space between the hexagonal prisms 2 and the hexagonal holes is filled with an adhesive curing liquid for forming a sealing interface.

[0052] The working principle and technical effects of the above scheme are as follows:

[0053] The liner body 1 has multiple hexagonal holes, and multiple hexagonal prisms 2 are respectively embedded in these hexagonal holes. This embedded structure provides a basic structural framework for the entire ceramic liner configuration, fixing the hexagonal prisms 2 to the liner body 1 so that the two can work together. An adhesive curing liquid is filled between the hexagonal prisms 2 and the hexagonal holes. After the liquid solidifies, it forms a sealed interface, further enhancing the connection stability between the hexagonal prisms 2 and the liner body 1, and preventing the hexagonal prisms 2 from loosening or falling off when impacted by coke. The hexagonal prisms 2 have multiple edges. When coke impacts the hexagonal prisms 2, these edges form continuous cutting edges. During the contact process between the coke and the edges of the hexagonal prisms 2, the coke will be subjected to cutting and crushing action by the edges. The stress concentration at the edges can more easily destroy the structure of the coke, breaking larger coke blocks into smaller particles. Smaller coke particles are more likely to fall off the liner surface after impact, rather than adhering to the liner as easily as larger coke blocks. Therefore, by crushing the coke, the amount of coke adhering to the liner surface is effectively reduced, ensuring the cleanliness of the liner surface and reducing equipment malfunctions and efficiency reductions caused by coke adhesion. Furthermore, the presence of the hexagonal prism 2 distributes the impact and wear of the coke on the liner body 1. During the coke impact process, the hexagonal prism 2 first contacts the coke and bears most of the impact and friction forces. The multiple edges of the hexagonal prism 2 also distribute the wear across multiple areas, rather than concentrating it at a single point or in a specific region. This effectively reduces the wear on the liner body 1, thereby improving the overall wear resistance of the ceramic liner, extending its service life, and reducing equipment maintenance costs and replacement frequency.

[0054] The hexagonal prism 2 has rounded corners. When the hexagonal prism 2 is impacted by coke, the corners are areas of stress concentration. Sharp corners cause stress to accumulate at these points, easily leading to material damage such as cracks. The rounded structure distributes stress more evenly across the surface of the hexagonal prism, preventing excessive stress concentration at the corners, enhancing the overall impact resistance, and improving its structural stability and reliability. The rounded structure also changes the direction of force during coke impact. When coke impacts the rounded corners, the force is dispersed along the curved surface, and some of the impact force is guided in other directions, reducing the direct impact force on the corners and further reducing the risk of damage due to excessive stress. The rounded structure makes the corners smoother, strengthens the corner areas, reduces the possibility of corner breakage, and ensures the integrity and functionality of the hexagonal prism. By reducing stress concentration and preventing corner breakage, the rounded structure helps slow down the wear and damage rate of the hexagonal prism, thereby extending its service life. Under the same operating conditions, hexagonal prisms with rounded edges can maintain good performance for a longer period of time, reducing the frequency of replacement and lowering maintenance costs.

[0055] The wall of the hexagonal hole is provided with a bearing ring, which is connected to the top of the hexagonal prism 2.

[0056] The hexagonal prism 2 has a spherical impact-resistant structure 3 at the end away from the liner body 1. When coke impacts the spherical impact-resistant structure 3 vertically, according to the principle of force decomposition, the spherical surface will decompose the vertical impact force of the coke into multiple radial components. The radial components will be dispersed in different directions instead of acting directly on the liner body 1, thereby reducing the vertical impact damage of the coke to the liner body 1.

[0057] The liner body 1 is provided with multiple interlocking areas. Each interlocking area is provided with multiple rows of hexagonal holes in the horizontal direction or multiple columns of hexagonal holes in the vertical direction. The rear ends of multiple hexagonal prisms 2 in the multiple rows of hexagonal holes contact and cooperate with multiple rows of horizontal supports on the back of the liner body 1. The rear ends of multiple hexagonal prisms 2 in the multiple columns of hexagonal holes contact and cooperate with multiple columns of vertical supports on the back of the liner body 1. The spherical impact-resistant structures 3 on the multiple hexagonal prisms 2 are all located in the groove at the front of the liner body 1. The contact ends of the hexagonal prisms 2 with the horizontal or vertical supports are all hemispherical contact surfaces 4. When coke impacts the liner, the impact energy is transmitted through numerous distributed hexagonal prisms 2. The rear ends of the hexagonal prisms 2 within multiple rows of hexagonal holes contact and engage with multiple rows of horizontal supports, while the rear ends of the hexagonal prisms 2 within multiple rows of hexagonal holes contact and engage with multiple rows of longitudinal supports. This allows the impact force to be transmitted not only between the hexagonal prisms 2 but also dispersed over a larger area through the horizontal and longitudinal supports. Compared to a structure with a single or few hexagonal prisms, this avoids excessive stress in localized areas and disperses the impact force over a larger area, effectively improving the overall impact resistance of the liner. The horizontal and longitudinal supports provide additional support and fixation for the hexagonal prisms 2. When subjected to coke impact, vibration, or other external forces, they limit the displacement of the hexagonal prisms 2. This ensures that the hexagonal prisms 2 are stably embedded within the hexagonal holes, preventing them from loosening or falling off even under high-impact environments, thus guaranteeing the integrity and stability of the liner structure. The horizontal and longitudinal supports are distributed on the back of the liner body 1, serving to strengthen the structure. When subjected to external forces, these surfaces resist deformation of the liner, keeping it flat and helping to maintain the integrity of the internal structure. The contact ends between the hexagonal prism 2 and the horizontal or vertical supports are hemispherical. These hemispherical surfaces allow for a more uniform distribution of contact stress between the hexagonal prism 2 and the horizontal or vertical supports, preventing component damage caused by localized stress concentration. Compared to planar contact, hemispherical contact surfaces better buffer and disperse stress when subjected to impact or vibration, further improving the stability and reliability of the liner structure and extending its service life.

[0058] The distance between opposite sides of the hexagonal hole is 15-18mm, preferably 15mm or 18mm. This distance range provides the best performance and stability for embedding the hexagonal prism 2, as shown in the table below:

[0059] Wear life 14-16 months ≥24 months 20-22 months thermal shock resistance >25 times (Excellent) >30 times (optimal) 15-18 times (good) Interface integration 92% pass rate 96% pass rate Pass rate 88% Casting yield 85％ 93％ 79％

[0060] The size of the distance between opposite sides of the hexagonal hole affects the embedding of the hexagonal prism 2. When the distance between opposite sides is set at 15-18mm, the fit between the hexagonal prism 2 and the hexagonal hole reaches a relatively ideal state. This size will not make the hole too large, causing the hexagonal prism 2 to loosen, nor too small, making embedding difficult or generating excessive assembly stress. The appropriate fit allows the hexagonal prism 2 to be stably fixed in the hole, and when subjected to external forces, it can effectively transmit and disperse the force, thereby ensuring the stability of the entire ceramic liner structure.

[0061] Different distances between the sides result in different stress distributions between the hexagonal prism 2 and the hexagonal hole. With a distance of 15-18mm between the sides, thermal and mechanical stresses can be distributed more evenly on the hexagonal prism 2 and the liner body. When the liner is subjected to temperature changes or external impacts, the uniform stress distribution can avoid local stress concentration, reduce the generation and propagation of cracks caused by stress concentration, and thus improve the thermal shock resistance and wear resistance of the liner.

[0062] During the manufacturing process, the size of the edge distance affects the implementation of processes such as inlay casting. A edge distance of 15-18mm makes it easier to accurately embed the hexagonal prism 2 into the hexagonal hole. Furthermore, during the inlay casting process, the liquid metal can better fill the gaps, reducing the generation of defects such as porosity and slag inclusions, thereby improving the inlay casting yield and the pass rate of interface bonding.

[0063] Based on the wear life data, when the distance between the two sides is 15-18mm, the wear life is ≥24 months, significantly higher than that for 12mm diameter (14-16 months) and 22mm diameter (20-22 months). This is because the appropriate distance between the two sides allows for a tighter and more stable connection between the hexagonal prism 2 and the liner body, enabling better cooperation and resistance to wear. Simultaneously, the uniform stress distribution reduces the problem of overall wear resistance degradation caused by excessively rapid localized wear, ensuring that the cross-sectional area of ​​the wear-resistant volume is ≥168mm². 2 This improves the wear resistance of the liner.

[0064] In terms of thermal shock resistance, when the edge distance is 15-18mm, the thermal shock resistance is >30 cycles (optimal), which is better than the other two size ranges. This is because the stress distribution is uniform under this size. When the temperature changes rapidly, the liner can better withstand the effect of thermal stress, reduce the generation and propagation of cracks caused by thermal stress, and thus improve the thermal shock resistance performance. The thermal stress is ≤350MPa.

[0065] The interface bonding pass rate reached 96%, and the inlay casting yield reached 93%, both higher than other size ranges, indicating that a 15-18mm side-to-side distance is beneficial to improving the stability of the manufacturing process. During the inlay casting process, the appropriate dimensions ensured a moderate gap between the hexagonal prism 2 and the hexagonal hole, allowing the liquid metal to fully fill and form a good interface bond. This reduced defects caused by process issues and improved product quality and reliability.

[0066] In summary, setting the distance between opposite sides of the hexagonal holes to 15-18mm can achieve better results in terms of thermal stress, wear resistance volume, and process stability, thereby improving the overall performance of ceramic liners.

[0067] The adhesive curing solution is aluminum dihydrogen phosphate adhesive, which has good structural stability after curing.

[0068] The surface of the liner body 1 is coated with a thermal shock resistant coating, which can improve the thermal shock resistance, wear resistance and corrosion resistance of the liner body 1, reduce the damage and replacement frequency of the liner, thereby reducing the maintenance cost and downtime of the equipment and improving production efficiency.

[0069] Example 2:

[0070] like Figures 1-5 As shown, a manufacturing method for producing the aforementioned high-coverage, anti-adhesion ceramic liner configuration includes the following steps:

[0071] Step S1: Making the white mold for the lost foam casting:

[0072] The lost foam white mold of the liner body 1 is made of EPS+PMMA copolymer beads;

[0073] Machining hexagonal holes on the white mold, with a side-to-side distance of 15-18mm;

[0074] A bearing ring is machined along the wall of the hexagonal hole;

[0075] Step S2, Ceramic column pretreatment:

[0076] ZTA20 ceramic was used to process the hexagonal prism 2, and rounded structures were set at the corners of the hexagonal prism 2;

[0077] Grind a spherical impact-resistant structure 3 at the end of the hexagonal prism 2 away from the root;

[0078] Hexagonal prism 2 was preheated at 850℃ to relieve stress;

[0079] Step S3, Inlaying, Positioning, and Sealing:

[0080] The hexagonal prism 2 is embedded in the hexagonal hole of the white mold, so that the bearing ring is connected to the top of the hexagonal prism 2;

[0081] Fill the gap between the hexagonal prism 2 and the hexagonal hole with adhesive curing liquid, and a sealed interface is formed after curing;

[0082] Step S4, Application of thermal shock resistant coating:

[0083] The thermal shock resistant coating is dipped into the surface of the white mold and then dried in stages to form a thermal shock resistant coating.

[0084] Step S5, Dry Sand Molding and Pouring:

[0085] The white mold was filled with 4070 mesh abrasive and compacted by vertical vibration under a vacuum of 0.05 MPa.

[0086] Then molten steel is poured in at a temperature of 1580±20℃, maintaining a negative pressure of 0.04MPa and an exhaust flow rate of ≥30m³ throughout the process. 3 / min, to obtain the liner body casting 1;

[0087] Step S6, Post-processing enhancement:

[0088] The liner body 1 casting is subjected to solution aging heat treatment, and the gaps between multiple hexagonal prisms 2 on the liner body 1 are filled with ramming material. After curing with aluminum dihydrogen phosphate binder, the high-coverage anti-adhesion ceramic liner configuration is obtained. The ramming material can enhance the integrity and stability of the liner, while also helping to improve the anti-adhesion performance of the liner, making the liner more durable during use and better able to exert its anti-adhesion properties.

[0089] The raw materials in the ramming mix are as follows by percentage: 60% fused alumina, 25% recycled ZTA powder, 1.5% steel fiber, and 13.5% composite binder.

[0090] The working principle and technical effects of the above scheme are as follows:

[0091] In the manufacturing method of this utility model, EPS+PMMA copolymer beads are used to create a lost foam casting with hexagonal holes and a side-to-side distance of 15-18mm, forming a precise ceramic column insertion structure. The edges of the ceramic columns are rounded, and the domes are ground to a profile accuracy of no more than 0.05mm. Preheating at 850℃ eliminates stress concentration and prevents casting vaporization. Aluminum dihydrogen phosphate binder with a temperature resistance exceeding 1000℃ is used to form a low-stress interface with a shear stress of 175MPa and good stability. The thermal shock resistant coating is formed by applying a suspension of 70% zircon powder and 5% nano-zirconia, and is dried in stages to achieve a thickness of 1.2-1.4mm, reducing the peak thermal stress to 1520MPa, a 31% reduction compared to traditional methods. Dry sand molding is performed using 40-70 mesh abrasive beads, followed by vertical vibration with an acceleration of 12m / s². 2The ceramic column was vibrated for 3 minutes and poured at 1580℃ with a negative pressure of -0.04MPa applied to ensure that the density of the sand around the ceramic column was greater than 1.75g / cm³. 3 Finally, the substrate is solution treated at 1150℃ and aged at 750℃, and then filled with ramming mix consisting of 60% fused alumina and 25% ZTA recycled powder, which increases the compressive strength of the matrix to 2450MPa, an improvement of 188% compared to traditional lining plates.

[0092] Compared with traditional liners, the ceramic liner of this invention has significant improvements in several performance indicators. The amount of coke adhering to the surface is reduced from 15 kg per square meter per month to 1.5 kg, a reduction of 90%, verified by weighing after 30 days of coke oven operation; the depth of the substrate pit is reduced from 3.5 mm to 0.8 mm, a reduction of 77%, verified by impact testing with a 3m coke drop (3D scanning); the thermal shock cycle life is increased from 50 cycles to over 700 cycles, a 14-fold increase, verified by a 1050℃ and air-cooled cycling test until cracking; the compressive strength is increased from 850 MPa to 2450 MPa, a significant improvement, verified according to GB / T7314-2017 standard; and the annual maintenance cost is reduced from 500,000 yuan to 28,000 yuan, effectively reducing costs, verified by the coking plant's annual operation and maintenance report.

[0093] The application is adapted to the high-coverage anti-adhesion ceramic liner configuration, which is installed in the upper oxidation zone of a coke oven to block the impact of falling coke and break up the coke adhesion layer.

[0094] The high-coverage, anti-adhesion ceramic liner configuration of this invention, when installed in the upper oxidation zone of a coke oven (furnace temperature 1050-1100℃), demonstrates excellent application results. The closely spaced hexagonal prisms achieve a 96% wear-resistant coverage rate with no blind spots; the edges continuously break up the coke layer, preventing deformation and failure caused by heat accumulation. The liner has a lifespan of 30-36 months, offering long service life and low maintenance costs.
