Description

Technical Field

[0001] The present invention belongs to the technical field of iron and steel metallurgy, and particularly relates to a multiphase reaction wetting device and a test method. Background Art

[0002] With the increasing requirements for high efficiency, energy conservation and environmental protection in the iron and steel production process, traditional ironmaking, smelting and other processes are facing increasing pressure in aspects such as energy conservation and emission reduction, and comprehensive utilization of resources. The slag-iron-carbon reaction is one of the key chemical reactions in the metallurgical process. Especially in the blast furnace ironmaking process, the interaction among slag, iron and carbon determines the efficiency of the metallurgical reaction and the quality of steel products. However, in the traditional blast furnace smelting process, the wettability of the slag and iron melts with coke and refractory materials directly affects the gas permeability and liquid permeability of the blast furnace. Therefore, it is extremely important to clarify their wetting characteristics during the smelting process.

[0003] During the blast furnace production process, a multiphase interaction process of molten iron, molten slag, coke and refractory materials will occur in the part below the softening-melting zone. The wetting behavior of molten iron and molten slag with coke or refractory materials not only causes erosion, but also affects the change of gas permeability and liquid permeability inside the blast furnace hearth.

[0004] In current research, researchers only focus on the wetting behavior process of the melt with a single carbon substrate, and often ignore the multiphase interaction process of molten iron, molten slag, coke and carbonaceous refractory materials caused by the complex environment inside the blast furnace. For example, the Chinese patent with the publication number CN117030545B discloses a test device and a test method for studying the wetting process of the iron-carbon reaction. In this test method, only the wetting process of molten iron and carbonaceous materials is considered, only one carbon substrate is considered, and the wetting behavior of the second-phase liquid slag in the carbon substrate is not considered. Another example is the Chinese patent with the publication number CN116150996A, which proposes a device and a method for measuring the dynamic wetting angle. However, this technology also only involves two-phase reactions, and only the wetting behavior process of the melt with a single carbon substrate is considered. Another example is the Chinese patent with the publication number CN117233043B, which discloses a method and application for determining the synergistic wetting behavior of iron-slag on the surface of carbonaceous materials. Although the synergistic wetting behavior of two melts, molten slag and molten iron, on the surface of carbonaceous materials is considered, this method still considers only one carbon substrate, and it is difficult to fully consider the influence of the synergistic effect between molten slag and molten iron on the multiphase wetting behavior of the surfaces of two carbonaceous materials. As a result, it is difficult to provide more accurate guidance for improving the gas permeability and liquid permeability of the blast furnace, affecting the stability of blast furnace operation. Summary of the Invention

[0005] To solve the problems existing in the prior art, the object of the present invention is to provide a multiphase reaction wetting device and test method, which can fully consider the influence of the synergistic effect between two melts on the multiphase wetting behavior of the surfaces of two carbonaceous materials, and can deeply analyze the synergistic wetting process between the two melts on the surfaces of the two carbonaceous materials, so as to provide effective guidance for improving the air permeability and liquid permeability of blast furnaces and ensure the stability of blast furnace operation.

[0006] The technical solution of the present invention is as follows:

[0007] A multiphase reaction wetting device and test method, including a horizontal furnace, a multiphase reaction unit, and a collection and analysis unit. The multiphase reaction unit is placed in the horizontal furnace. The multiphase reaction unit includes a suspension assembly and a support body. The top of the support body has a placement groove for respectively placing two carbonaceous plates and a first melt. The suspension assembly is arranged above the opening of the placement groove and is connected to the support body. The suspension assembly is used to suspend a second melt. The collection and analysis unit includes a processor and at least two image collectors. The two image collectors are respectively placed at both ends of the horizontal furnace. The two image collectors are both electrically connected to the processor. The two image collectors are used to record the angle changes of the wetting of the first melt and the second melt with the two carbonaceous plates. The processor is used to analyze the interactive influence of the wetting behaviors of the two carbonaceous plates with the first melt and the second melt according to the obtained angle changes. Using the placement groove to place and support two carbonaceous plates of different materials facilitates the placement of the first melt between the two carbonaceous plates. Furthermore, the suspension assembly enables the second melt to be suspended between the two carbonaceous plates. When heating the horizontal furnace, since the suspended second melt and the first melt are at different height positions, mutual blocking is avoided, enabling the image collectors on both sides to clearly record the melting process of the two melts in the horizontal furnace, so as to study the multiphase synergistic reaction wetting process between the two melts and the two different carbonaceous materials.

[0008] Preferably, the placement groove is arranged in a V shape. Using the V-shaped placement groove can provide a more stable contact effect for the placement of the two carbonaceous plates, meet the position setting requirements of the two carbonaceous plates, and facilitate the development of the test.

[0009] Preferably, the support body includes a base and two relatively arranged support blocks. The two support blocks are both cylinders with an isosceles right triangle cross-section. The two support blocks are respectively fixed to the base through a right-angled side, and the hypotenuses of the two support blocks are connected end to end. With the above setting, the angle of the placement groove is 90 degrees, which is convenient for the stable support of the two carbonaceous plates during the test, and also simplifies the shapes of the two carbonaceous plates and the first melt between them, enabling the two carbonaceous plates to fully contact the first melt between them.

[0010] The support block is made of a material with high thermal conductivity to ensure that the temperatures of the first melt and the second melt are sufficiently close, so as to obtain accurate test results.

[0011] Preferably, the image collector includes a high-speed camera, which can clearly record the experimental process for facilitating the extraction of the wetting angle.

[0012] Preferably, both sides of the horizontal furnace opposite to the image collector are made of transparent materials, which is convenient for the high-speed camera to take pictures outside the horizontal furnace, avoiding the internal gas of the horizontal furnace from adhering to the lens of the high-speed camera and ensuring the clarity of the shooting.

[0013] Preferably, the test method of the multiphase reaction wetting device includes the following steps:

[0014] Place two carbon plates made of different materials end to end in the placement groove, and make the angle formed by the two carbon plates face the opening of the placement groove.

[0015] Place the first melt between the angles of the two carbon plates to form a state of common contact with the two carbon plates. Suspend the second melt above the angle of the two carbon plates through the suspension assembly, on one side of the first melt, and the vertical projection of the second melt is tangent to the first melt.

[0016] Fill the inside of the horizontal furnace with inert gas and heat it up to melt both the first melt and the second melt. After the second melt melts, it drips between the two carbon plates and contacts the solution of the first melt, and wetting behavior occurs with the two carbon plates.

[0017] Use the image collector to record the wetting processes of the first melt and the second melt with the two carbon plates respectively and upload them to the processor. The processor extracts the wetting angles of the first melt and the second melt with the two carbon plates during the wetting process through the recorded video to obtain the variation rules of the wetting angles of the first melt and the second melt with the two carbon plates.

[0018] Compared with the prior art, a multiphase reaction wetting device and a test method of the present invention have the following beneficial effects:

[0019] The test method provided by this device can study the multiphase cooperative reaction wetting process of two melts with two different carbon materials, can simulate the wetting contact behavior of the slag and iron melts in contact inside the blast furnace with two different carbon materials, and can observe and obtain the changes in the wetting angles of the molten iron and molten slag with the two types of carbon materials throughout the process through the image collector, and can deeply analyze the cooperative wetting process between the slag and iron melts on the surfaces of the two carbon materials, thereby providing effective guidance for improving the gas permeability and liquid permeability of the blast furnace and ensuring the stability of the blast furnace operation.

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts fall within the protection scope of the present invention.

[0029] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0030] See Figures 1 to 5As shown in the figure, in order to fully consider the synergistic effect between the two melts on the multiphase wetting behavior of the surfaces of the two carbonaceous materials, the synergistic wetting process between the slag and iron melts on the surfaces of the two carbonaceous materials is deeply analyzed, providing effective guidance for improving the air permeability and liquid permeability of the blast furnace and ensuring the stability of the blast furnace operation. This embodiment provides a multiphase reaction wetting device, which includes a horizontal furnace 1, a multiphase reaction unit, and a collection and analysis unit. The horizontal furnace 1 is a cylindrical sealed cavity. The multiphase reaction unit is placed in the horizontal furnace 1. The multiphase reaction unit includes a suspension assembly 2 and a support body 3. The top of the support body 3 has a placement groove 5. Two carbonaceous plates 4 are placed in the placement groove 5. The two carbonaceous plates 4 intersect and have an included angle with the same opening direction as the placement groove 5. The suspension assembly 2 is arranged above the opening of the placement groove 5 and is connected to the support body 3. Specifically, the suspension assembly 2 can be composed of a horizontally arranged crossbeam, a steel wire rope, and a mesh bag. The crossbeam is fixed to the support body 3 through a column, keeping the crossbeam directly above the opening of the placement groove 5. The mesh bag is fixed to the crossbeam through a pull rope. The first melt 6 is placed between the included angles of the two carbonaceous plates 4. The suspension assembly 2 is used to suspend the second melt 7 through the mesh bag. The melting point of the preferably selected mesh bag should be much higher than that of the second melt 7. The collection and analysis unit includes a processor 8 and at least two image collectors 9. The two image collectors 9 are respectively placed at both ends of the horizontal furnace 1. The image collectors 9 are preferably high-speed cameras, and the two image collectors 9 are located on the two sides adjacent to the two carbonaceous plates 4. The two image collectors 9 are both electrically connected to the processor 8. The two image collectors 9 are used to record the angular changes of the wetting of the two carbonaceous plates 4 by the first melt 6 and the second melt 7. The processor 8 is used to analyze the interactive effects of the wetting behaviors of the two carbonaceous plates 4 on the first melt 6 and the second melt 7 according to the obtained angular changes.

[0031] See Figures 1 to 4 As shown in the figure, further, in order to improve the accuracy of the experiment and facilitate the recording and analysis of the experimental process, the following specifications are made:

[0032] 1. Both of the two carbonaceous plates 4 are set as rectangular parallelepiped plates with the same size, and the two carbonaceous plates 4 are connected end to end and are placed perpendicular to each other in the placement groove 5.

[0033] 2. The design of the support 3 is such that the support 3 includes a horizontally arranged base 31 and two oppositely arranged support blocks 32. The two support blocks 32 are prisms with an isosceles right triangle cross-section. The two support blocks 32 are respectively fixedly connected to the base 31 through a right-angled side, and the hypotenuses of the two support blocks 32 are connected end to end, thereby forming a V-shaped placement groove 5 with an included angle of 90 degrees on the upper side of the base 31, that is, the side of the placement groove 5 opposite to its opening is set at a right angle. The two carbon plates 4 are respectively attached to the two right-angled sides of the placement groove 5. The two support blocks 32 are made of pure graphite material. Graphite material has high thermal conductivity, low thermal expansion coefficient, high temperature strength, high temperature oxidation resistance, good chemical stability, radiation resistance and corrosion resistance, etc. These advantages enable graphite to ensure the smooth completion of the experiment in metallurgy, ensure that the temperatures received by the first melt 6 and the second melt 7 are sufficiently close, so as to obtain accurate experimental results. Utilizing the 90-degree angle of the placement groove 5 is convenient for the stable support of the two carbon plates 4 during the experiment, and also convenient for simplifying the shapes of the two carbon plates 4 and the melt between them, enabling the two carbon plates 4 to fully contact the melt between them.

[0034] 3. Both sides of the horizontal furnace 1 opposite to the image collector 9 are made of transparent materials, preferably high-temperature resistant glass, which can withstand temperatures above 1600 °C. And inert gases such as helium (He), neon (Ne), etc. need to be filled in the horizontal furnace 1 during the experiment. Using inert gases can avoid the influence of the external environment and only consider the interaction between the objects under study. If the type of gas is not considered, it is necessary to further include the influence of the gas environment as a participating item in the final result analysis to ensure the accuracy of the analysis result.

[0035] 4. The first melt 6 and the second melt 7 are made into cube structures with equal side lengths before being melted at high temperature, which is convenient for full contact with the two carbon plates 4 during the experiment.

[0036] 5. It is required that the shooting rate of the high-speed camera can reach 1000 frames per second, and the shooting temperature should be higher than 1650 °C. It can achieve clear video shooting of the experimental process, which is convenient for extracting the wetting angle. At the same time, both sides of the horizontal furnace 1 opposite to the high-speed camera are made of transparent materials, which is convenient for the high-speed camera to shoot outside the horizontal furnace, avoiding the internal gas of the horizontal furnace 1 from adhering to the lens of the high-speed camera and ensuring the clarity of the shooting.

[0037] 6. The materials of the two carbon plates 4 are respectively made of graphite and coke. The waist length is preferably set to 5 cm, and the overall length of the support block 32 is preferably set to 8 cm.

[0038] According to the design of the above-mentioned multiphase reaction wetting device, the following two forms of experiments can be carried out:

[0039] First, see Figure 1 andFigure 4 As shown, a multiphase cooperative wetting test of a single melt and two different carbonaceous materials, the test method comprising the following steps:

[0040] Place two carbonaceous plates 4 of different materials end to end in the placement groove 5, and make the angle formed by the two carbonaceous plates 4 face the opening of the placement groove 5.

[0041] Place the first melt 6 or the second melt 7 between the angles of the two carbonaceous plates 4 to form a state of common contact with the two carbonaceous plates 4.

[0042] Fill the inside of the horizontal furnace 1 with an inert gas and heat it up to melt the first melt 6 or the second melt 7. After melting, a reaction wetting behavior occurs with the two carbonaceous plates 4.

[0043] Use a high-speed camera to record the wetting process on both sides of the first melt 6 or the second melt 7 respectively, and upload it to the processor 8. The processor 8 extracts the wetting angle of the first melt 6 or the second melt 7 during the wetting process through the obtained video. The wetting angles are the angles represented by α and β in the appendix. Since the first melt 6 or the second melt 7 has a certain viscosity after melting, the angles with the two carbonaceous plates are also different. Through the analysis of the wetting angles by the processor 8, the variation law of the wetting angles of the first melt 6 or the second melt 7 with the two carbonaceous plates is obtained. Figure 5 Through the analysis of the obtained wetting angle variation law and the samples of the first melt or the second melt after the reaction, the wetting and dissolution conditions when the first melt 6 or the second melt 7 is in contact with the two carbonaceous plates 4 simultaneously are analyzed.

[0044] Secondly, as shown in

[0045] Secondly, as shown in Figure 1 and Figure 3 a multiphase cooperative wetting test of two melts and two different carbonaceous materials, the test method comprising the following steps:

[0046] Place two carbonaceous plates 4 of different materials end to end in the placement groove 5, and make the angle formed by the two carbonaceous plates 4 face the opening of the placement groove 5.

[0047] Place the first melt 6 between the angles of the two carbonaceous plates 4 to form a state of common contact with the two carbonaceous plates 4. Suspend the second melt 7 above the angle between the two carbonaceous plates 4 through the suspension assembly 2 so that it is located on one side of the first melt 6, and the vertical projection of the second melt 7 is tangent to the first melt 6.

[0048] The horizontal furnace 1 is filled with an inert gas and heated up to melt both the first melt 6 and the second melt 7. After the second melt 7 melts, it drips between the two carbonaceous plates 4 and comes into contact with the solution of the first melt 6, forming a reaction wetting behavior where the solutions of the first melt 6 and the second melt 7 are in contact while reacting with the two carbonaceous plates 4.

[0049] Use a high-speed camera to record the wetting processes on both sides respectively and transmit them to the processor 8. The processor 8 extracts the wetting angles of the first melt 6 and the second melt 7 during the wetting process from the recorded videos. The wetting angles are the angles represented by α and β in the appendix. Since the first melt 6 and the second melt 7 have a certain viscosity after melting, their angles with the two carbonaceous plates are also different. The processor 8 processes and analyzes the obtained wetting angles to obtain the variation laws of the wetting angles of the first melt 6 and the second melt 7 with the two carbonaceous plates 4 respectively. It should be noted here that the method for obtaining the angle between the two carbonaceous plates 4 where the suspended second melt 7 drips after melting is the same as the method for obtaining the wetting angle of the first melt 6 after melting between the two carbonaceous plates 4. Figure 5 Using laboratory analysis means, analyze the reacted first melt 6 and second melt 7 and the obtained variation laws of the wetting angles of the first melt 6 and the second melt 7 with the two carbonaceous plates 4, and analyze the melting situation of the first melt 6, the second melt 7 and the two carbonaceous plates 4 when heated and melted simultaneously between the two different carbonaceous plates 4.

[0050] Specifically, using the method of the above reaction wetting device, the experimental operation method for the multiphase cooperative wetting of slag, iron melt and graphite, coke carbonaceous materials is as follows:

[0051] I. The experimental steps for the multiphase cooperative wetting of any one of the slag and iron melts with two different carbonaceous materials, graphite and coke, are as follows:

[0052] (1) Obtain an iron block by melting iron powder, and then prepare an iron block with a side length of 1 cm by cutting. Cut and prepare 1 graphite plate body (the first carbonaceous plate 4) with dimensions of 50 mm * 30 mm * 10 mm and 1 coke plate body (the second carbonaceous plate 4) with dimensions of 50 mm * 30 mm * 10 mm.

[0053] (2) Place the graphite plate body and the coke plate body vertically in the right-angled placement groove 5 on the upper side of the graphite support 3 in the manner shown, ensuring that the graphite plate body and the coke plate body are completely fitted with the two right-angled sides of the placement groove 5.

[0054] (3) Place the iron block at the position of the first melt 6 as shown, so that it forms a state of being in contact with both graphite and coke. Figure 2 Ensure that the graphite plate body and the coke plate body are completely fitted with the two right-angled sides of the placement groove 5.

[0055] (3) Place the iron block at the position of the first melt 6 as shown, so that it forms a state of being in contact with both graphite and coke. Figure 2 Make it form a state of contacting both graphite and coke.

[0056] (4)Fill the inside of the horizontal furnace 1 with an inert gas and heat it up to 1500 °C to melt the iron block, causing a reaction wetting behavior with the graphite plate body and the coke plate body.

[0057] (5)Use a high-speed camera to record the wetting processes on both sides respectively and upload them to the processor 8. The processor 8 extracts the wetting angles of the wetting processes to obtain the changes in the wetting angles between the molten iron and graphite and between the molten iron and coke respectively, with a total of 2 wetting angle changes.

[0058] (6)Use laboratory analysis means, including methods such as Scanning Electron Microscope and Computed Tomography, to analyze the reacted samples, and analyze the extracted laws of wetting angle changes to analyze the wetting and dissolution conditions when the molten iron is in contact with graphite and coke simultaneously.

[0059] Preferably, replace the iron block in the above steps with a slag block, so as to analyze the wetting and melting conditions when the slag liquid is in contact with graphite and coke simultaneously.

[0060] II. The test steps for the multiphase cooperative wetting of two melts of slag and iron with two different carbonaceous materials of graphite and coke are as follows:

[0061] (1)Prepare an iron block by melting iron powder, and then cut it to obtain an iron block with a side length of 1 cm. Prepare a slag block with a side length of 1 cm by pressing. Cut and prepare a graphite plate body with dimensions of 50 mm * 30 mm * 10 mm and a coke plate body with dimensions of 50 mm * 30 mm * 10 mm.

[0062] (2)Place the graphite plate body and the coke plate body vertically on the graphite support 3 in the manner as shown. Figure 3 shown.

[0063] (3)Place the slag block between the graphite plate body and the coke plate body and make it contact with both the graphite plate body and the coke plate body simultaneously (at the position shown by the first melt 6). Suspend the iron block above the angle between the graphite plate body and the coke plate body, make it located on the side of the slag block, and ensure that the vertical projection of the iron block is tangent to the slag block (at the positions shown by the second melt 7 in and). Figure 2 and Figure 2 and Figure 3 shown).

[0064] (4)Fill the inside of the horizontal furnace 1 with an inert gas and heat it up to 1500 °C to melt the iron block and the slag block. After the iron block melts, it drips between the graphite plate body and the coke plate body and contacts the molten slag, forming a contact between the molten iron and the slag liquid, and the molten iron and the slag liquid both react and wet the graphite and coke plate bodies simultaneously.

[0065] (5)The wetting processes on both sides were recorded separately using a high-speed camera. Images were extracted every 30 s, and the wetting angles during the wetting processes were extracted to obtain the changing trends of the wetting angles between the molten iron, molten slag and the two carbonaceous material substrates, a total of four wetting angle changes.

[0066] (6)Laboratory analysis means, including Scanning Electron Microscope, Computed Tomography, etc., were used to analyze the samples after the reaction, and the changing laws of the wetting angles corresponding to the extracted molten iron and molten slag were analyzed to analyze the wetting and dissolution conditions when the molten iron and molten slag were in contact with graphite and coke simultaneously.

[0067] This example is mainly used to study the internal phenomena of the blast furnace and the reaction mechanism during the simultaneous contact process of molten iron, molten slag with graphite-based refractories and coke.

[0068] In summary, the test method provided by this device can study the multi-phase synergistic reaction wetting process between two melts and two different carbonaceous materials, can simulate the wetting contact behavior between the slag and iron melts in contact inside the blast furnace and two different carbonaceous materials. Through the image collector 9, the changing wetting angles of the molten iron and molten slag with the two types of carbonaceous materials can be observed and obtained throughout the process, and the synergistic wetting process between the slag and iron melts on the surfaces of the two carbonaceous materials can be deeply analyzed, so as to provide effective guidance for improving the gas permeability and liquid permeability of the blast furnace and ensure the stability of the blast furnace operation.
