Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
In the following detailed description, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration specific embodiments in which the application may be practiced. In the drawings, like reference numerals describe substantially similar components throughout the different views. Various specific embodiments of the present application are described in sufficient detail below to enable those skilled in the art to practice the teachings of the present application. It is to be understood that other embodiments may be utilized or structural, logical, or electrical changes may be made to the embodiments of the present application.
As shown in fig. 1 to 6, the copper-steel-copper composite water jacket 100 of the present application includes: the explosion-compounded water jacket body 110, the water jacket body 110 is in a cuboid shape, and comprises a first copper layer 111 and a second copper layer 112 which are positioned on hot surfaces of two sides, and a steel layer 113 positioned between the first copper layer 111 and the second copper layer 112, after the explosion compounding, as shown in fig. 4, transition layers 114 are formed in areas of the steel layer 113 adjacent to the first copper layer 111 and the second copper layer 112 respectively.
With continued reference to fig. 1 and with reference to fig. 4 and 5, in the copper-steel-copper composite water jacket in the embodiment of the present application, a double explosion composite technology is adopted, first, explosion composite is performed on a layer of copper plate and a layer of steel plate, and then, second explosion composite is performed on a copper-steel composite plate obtained by the first explosion composite with the layer of copper plate, so as to manufacture a copper-steel-copper composite water jacket body with a layer of steel sandwiched between two copper layers. The copper-steel composite board manufactured by explosive cladding has the advantages of high bonding strength, good corrosion resistance, wide application range, simple process and the like, and provides a novel composite material with excellent performance for the field of blast furnace equipment. The water jacket produced by the explosion composite technology has higher bonding strength between the copper layer and the steel layer. Referring to fig. 4, the first copper layer 111 and the steel layer 113 are tightly fused together after explosive cladding, and the two layers of copper and iron are fused to form a transition layer 114, and the nano indentation strength of the first copper layer 111, the steel layer 113 and the transition layer 114 are respectively tested in fig. 5, wherein in fig. 4, point a is taken from the first copper layer, point B is taken from the steel layer, point C is taken from the transition layer, and the nano indentation strength obtained by testing the first copper layer 111 is 3.790GPa; the nano indentation strength obtained by the steel layer 113 test is 9.011GPa; the nano indentation strength obtained by the test of the transition layer 114 is 15.707GPa, and the nano indentation strength of the transition layer is higher than that of the copper layer and higher than that of the steel layer, which indicates that the bonding strength of the copper layer and the steel layer of the water jacket body in the embodiment of the application is good, the performance of the transition layer is more superior, and meanwhile, the thermal shock deformation resistance of the water jacket body is excellent. The copper steel copper composite water jacket has the transition layer between two copper steels, and can further improve the strength of the water jacket. It should be noted that fig. 4 only illustrates the transition layer 114 between the first copper layer 111 and the steel layer 113, and the transition layer 114 is also present between the second copper layer 112 and the steel layer 113, and the structure and characteristics are similar to those described above, and are not repeated here.
The copper-steel explosion composite board has the advantages of copper and steel, and has good corrosion resistance even in a blast furnace with very severe use environment and facing smelting environment with thousands of DEG C or higher and scouring of high-temperature flue gas; moreover, compared with the traditional composite material preparation method, the explosion welding process is relatively simple. By proper treatment, the copper steel explosion composition with large area and large plate width can be realized. This contributes to a reduction in the production cost of the water jacket and an improvement in the production efficiency.
Continuing to see fig. 6, when the copper-steel-copper composite water jacket 100 of the present application is in use, the two sides of the copper-steel-copper composite water jacket can be supported by the support (not shown in the figure) to complete the installation, so that the reaction environment on one side in the first copper layer is similar to that in the blast furnace, the reaction environment on the other side of the second copper layer is similar to that in the blast furnace, the side faces upwards, and the water inlet pipe 131 and the water outlet pipe 132 are respectively positioned on the two sides. After one copper steel copper composite water jacket 100 is supported, a plurality of layers of copper steel copper composite water jackets 100 can be stacked on the copper steel copper composite water jacket to form a wall body in a gradual stacking mode, and two partial areas with different environments in a blast furnace are separated. In some embodiments, the length of the water jacket body can be adjusted according to the actual size requirement in the blast furnace, and the combination of the inverted trapezoid wall and the rectangular wall can be piled up as shown in fig. 6, so that the upper inverted trapezoid wall structure has the advantage of effectively reducing the problem of large deformation of the long-span water jacket. The longer the length of the water jacket, the larger the deformation amount of the middle part is influenced by gravity, and if the support of other water jackets is arranged below the water jacket with long span, the deformation amount of the long-span water jacket in the vertical direction can be reduced by combining the water jackets together to form an inverted trapezoid structure. In other embodiments, the composite water jacket provided in the present application may also be used by lifting two ends of the water jacket, which is a conventional manner of using a partition water jacket in the field, and will not be described herein.
As shown in fig. 1 to 8, a plurality of waterways 120 are respectively provided in the first copper layer 111 and the second copper layer 112; the two ends of the water channel 120 are respectively provided with a water inlet pipe 131 for cooling water to enter and a water outlet pipe 132 for cooling water to flow out. The advantage of arranging the water channels in the first copper layer and the second copper layer respectively is that the heat exchange effect of the composite water jacket can be improved. According to practical use and simulation analysis, the cooling effect of the double-layer water channel is better than that of a pure copper water jacket. In some embodiments, the water channel is formed by deep hole drilling, so that the water channel is convenient to process, and the heat exchange effect is better than that of a water channel cast by buried pipes.
Wherein, the length of the water jacket body 110 is 2.5m-5.5m. As the smelting furnace is bigger and bigger, the span of the partition wall water jacket is bigger and bigger, but the larger the span is, the bigger the self gravity is, the deformation of a flexible zone is more easy to occur at high temperature, cracks can be generated in the middle, even the cracks are penetrated and broken, the bottom is flushed to leak out the copper pipe, and the end surface copper pipe is cut due to the deformation of the water jacket. Therefore, the mechanical properties of the partition wall water jacket are critical to the ability to make a long span partition wall water jacket. The partition wall water jacket of 5m still can not be made in the trade at present, and the partition wall water jacket of this application embodiment can be made the long span about 5.5m through the test owing to mechanical properties is excellent, can adapt to large-scale smelting furnace.
Referring to fig. 1 to 3, the thickness of the steel layer 113 may be in the range of 8-30mm according to various needs in practical applications; the thickness of each of the first copper layer 111 and the second copper layer 112 may be in the range of 50mm to 100mm. The middle thickness of the three-layer copper steel copper composite board can be steel or stainless steel within the range of 8-30mm, and materials can be specified according to the reaction environment in the smelting furnace so as to improve the deformation resistance of the water jacket. In some embodiments, the copper layers on both sides may be rolled copper plates. The thickness of the steel layer is much smaller than that of the copper layer, but is critical to improving the mechanical properties of the copper-steel-copper composite water jacket. The copper layer is thicker, and a water channel with a larger inner diameter can be formed in the copper layer, so that the heat exchange capacity of the water jacket can be improved, and the service life of the water jacket can be prolonged.
At normal temperature, the deformation simulation test is carried out on the pure copper water jacket and the copper-steel-copper composite water jacket of one embodiment of the application, and the obtained simulation result shows that the deformation of the copper-steel-copper composite water jacket of the application at normal temperature is 0.5-0.7 times of the deformation of the pure copper water jacket.
In the simulation experiment, a pure copper water jacket and a copper steel copper composite water jacket which have the same total length and the same total thickness are adopted, wherein the total length of the two water jackets is 4500mm, and the total thickness is 160mm. In the copper steel copper composite water jacket, copper layers on two sides are respectively 70mm, a simulation diagram obtained by the copper layer in the middle is 20mm, the side surfaces of the two water jackets are respectively displayed in the length direction, ten different blocks are used for showing the total deformation of the water jacket, and the specific deformation of each block is shown in the following table.
From the above table, the deformation amounts are gradually increased from the two ends to the middle position of the water jackets, the block 1 is close to the two ends of the water jackets, the block 9 is located at the middle section of the water jackets, the deformation amount of the section is maximum, and the water jackets are located at the transverse positions, so that the most main factor causing the deformation of the water jackets is the gravity of the water jackets as can be seen from the distribution of the deformation amounts. It should be noted that the length of each block is not equidistant, but is formed by transition according to the deformation of the block, so that the length of the blocks of different water jackets can be different.
As is clear from the deformation data of each block in the deformation simulation test shown in the table, the maximum value of the deformation of the pure copper water jacket was 0.64676mm in the normal temperature environment. Under the same condition, the maximum deformation of the copper-steel-copper composite water jacket with the same length and the same thickness is only 0.43984mm, and the length of the block 9 positioned in the middle section of the water jacket is longest and occupies about 1/4 of the total length of the copper-steel-copper composite water jacket. The deformation of the copper-steel-copper composite water jacket under the same condition is 0.68 times of that of the pure copper water jacket. Therefore, the deflection area deformation of the copper-steel-copper composite water jacket is smaller, and the service life is longer.
Referring to fig. 2, 3 and 7, dovetail grooves 150 are respectively formed on the outer surfaces of the first copper layer 111 and the second copper layer 112 along the direction perpendicular to the length direction of the water jacket body, the groove depth of the dovetail grooves 150 is within the range of 5-25mm, the groove width is within the range of 20-50mm, and the groove body interval is within the range of 60-100mm. As shown in fig. 7, the depth of the dovetail groove 150 does not touch the water channel 120 formed in the copper layer, namely: the slag is not interfered with the water channel 120, so that slag can be easily hung, abrasion resistance, scouring resistance and corrosion resistance are realized, slag skin formed by the slag can be easily hung, the water jacket is protected, and the service life of the water jacket is prolonged; meanwhile, the dovetail groove can also increase the heat exchange area of the copper layer, enhance heat exchange and reduce the temperature of the water jacket, thereby reducing the deflection deformation of the water jacket caused by overhigh temperature.
Alternatively, according to an embodiment of the present application, the hole shape of the water channel 120 may include a single hole as shown in fig. 7 or multiple holes as shown in fig. 8, where the multiple holes include 2 or more round holes partially overlapping each other. To ensure substantial uniformity of cooling water flow, as in FIG. 8, when the holes of the water channel 120 are in the form of two-way holes, the centers of the two circular holes of the two-way holes are collinear; when the holes of the water channel 120 are multi-hole, such as tri-hole, the centers of the three holes are collinear, in other embodiments, multi-hole shapes such as tetra-hole and penta-hole may be formed, and at least two of the centers of the circular holes of the multi-hole are collinear. The multiple connecting holes can properly reduce the copper thickness, reduce the consumption of noble metal copper, lighten the dead weight and reduce the deflection deformation of the water jacket.
In some embodiments, the channel wall of the waterway 120 may also be textured with a predetermined shape for extending the perimeter of the cross-section of the waterway. The texture of the preset shape comprises thread shapes distributed on the pipeline wall, and the thread shapes are single thread shapes or multiple thread shapes extending along the length direction of the water channel so as to guide cooling water to flow out in a spiral mode, and the heat exchange area is increased.
Referring to fig. 8, according to an embodiment of the present application, alternatively, the pipe wall hole of the water channel 120 may be provided with a heat exchanging part having a predetermined shape, such as: the predetermined shape of the heat exchanging part is extended along the axial length direction of the water course 120 shown in fig. 8, which is a convex tooth on the outer contour thereof. The specific hole shape is not limited, can meet the field environment, and besides the common convex tooth hole shape and the thread hole shape, other special-shaped water channels can be formed, so that heat exchange is enhanced.
The copper steel copper composite water jacket provided by the application has the advantages that the two side surfaces of the steel layer are both compounded with one copper layer through the double-layer explosion composite technology, the mechanical strength of the water jacket is improved, the deflection deformation of the whole water jacket is small, the water channels are formed in the two copper layers, the heat exchange effect is good, various hole shapes can be formed according to actual requirements, and the weight of the copper layer is reduced. The copper steel copper composite water jacket provided by the application has long service life, and various operation indexes and economic indexes of the partition wall water jacket smelting furnace can be greatly improved.
The above embodiments are provided for illustrating the present application and are not intended to limit the present application, and various changes and modifications can be made by one skilled in the relevant art without departing from the scope of the present application, therefore, all equivalent technical solutions shall fall within the scope of the present disclosure.
