Abstract
Description
Technical Field
[0001] This application relates to the field of copper water jacket technology, and in particular to an oxygen-enriched side-blown furnace body cooling combined cast copper water jacket and an Osmette furnace. Background Technology
[0002] Copper, as an important industrial metal, is widely used in copper smelting technologies, particularly the Osmelt furnace top-blown smelting technology due to its mature process. However, in the traditional Osmelt furnace top-blown process, a high-temperature lance is inserted from the top of the furnace, and the resulting intense jet directly impacts the molten surface. This causes the refractory material in the furnace top area to suffer extreme thermal erosion and chemical corrosion, resulting in severe damage to the furnace lining and a shortened furnace life. This not only increases the cost of replacing refractory materials and downtime but also introduces safety risks. Side-blown smelting technology, with its advantages of high oxygen concentration, high energy utilization, less smoke and dust, and good economic benefits, has been increasingly widely used in the copper smelting field. Compared with the traditional Osmelt furnace top-blown technology, the side-blown Osmelt furnace can more effectively promote stirring and heat and mass transfer processes within the molten pool, improving metal recovery and smelting efficiency.
[0003] Currently, there is limited research on side-blown Ausmelt furnaces in the industry. Because the furnace body of a side-blown Ausmelt furnace is in a harsh environment of high temperature, strong heat radiation, and chemical corrosion, and the oxygen-enriched tuyeres of this type of side-blown furnace are located in the belly of the furnace, the high-temperature melt and strong thermal erosion can easily cause the furnace body refractory material to be corroded. In particular, the tuyeres are in direct contact with the high-temperature melt. If the refractory material is not continuously and uniformly cooled, it will seriously erode and penetrate the refractory matrix, change its composition and structure, and cause the material to loosen and fall off, thus shortening the furnace life of the side-blown Ausmelt furnace. Utility Model Content
[0004] This application aims to propose a copper water jacket combination for oxygen-enriched side-blown furnace body cooling and an Osmelt furnace, in order to solve the problems in related technologies where the furnace body refractory is easily eroded at high temperatures and the tuyeres are in direct contact with the high-temperature molten material, making them susceptible to erosion and penetration of the refractory matrix, thus shortening the lifespan of the Osmelt furnace.
[0005] To achieve the above objectives, embodiments of this application provide a copper-cast water jacket for oxygen-enriched side-blown furnace body cooling system in an Osmite furnace, comprising: The first toothed water jacket has a first through hole extending through it along its thickness direction, and several first cooling pipes are pre-embedded inside the first toothed water jacket. The second toothed water jacket is provided with a notch for slag discharge, and several second cooling pipes are pre-embedded in the second toothed water jacket. Several first toothed water jackets and several second toothed water jackets are spliced together to form the furnace body cooling structure of the Osmite furnace. The side-blowing gun water jacket is detachably connected to the first through hole. The side-blowing gun water jacket has a second through hole for fixing the high-temperature spray gun, and several third cooling pipes are pre-embedded in the side-blowing gun water jacket near the second through hole.
[0006] In some embodiments, the two end faces of the first toothed water jacket are respectively provided with a first connecting portion, and the two end faces of the second toothed water jacket are respectively provided with a second connecting portion connected to the first connecting portion.
[0007] In some embodiments, the arc radii of the arc segments formed by the projection of the heating surfaces of the first toothed water jacket and the second toothed water jacket along the first direction are the same, and the heating surface is the end face close to the inside of the Osmette furnace.
[0008] In some embodiments, multiple first cooling pipes are embedded in the first toothed water jacket and are staggered from the first through hole. The first cooling pipes are respectively provided with a first water inlet head and a first water outlet head at both ends. The first water inlet head and the first water outlet head extend outward from the same side end of the first toothed water jacket.
[0009] In some embodiments, the notch is located near the bottom region of the second toothed water jacket, and multiple second cooling pipes are embedded in the second toothed water jacket and staggered from the notch.
[0010] In some embodiments, the second cooling pipe is provided with a second water inlet head and a second water outlet head at both ends, and the second water inlet head and the second water outlet head extend outward from the same side end of the second toothed water jacket.
[0011] In some embodiments, the heating surfaces of the first toothed water jacket and the second toothed water jacket are respectively provided with slag-hanging grooves, and a plurality of slag-hanging grooves are spaced apart on the heating surfaces along a first direction.
[0012] In some embodiments, each of the slag-hanging grooves on the first toothed water jacket and the second toothed water jacket is arranged along a second direction, wherein the first direction is perpendicular to the second direction.
[0013] In some embodiments, the side-blowing gun water jacket is provided with a weld overlay wear-resistant layer near the heating surface inside the furnace, and the weld overlay wear-resistant layer completely covers the heating surface.
[0014] Compared with the prior art, the technical solutions provided by the above embodiments of this application have at least the following beneficial effects: The combined cast copper water jacket provided in this application, through the arrangement of a first toothed water jacket, a second toothed water jacket, and a side-blowing lance water jacket, achieves efficient cooling of the furnace body of the Ausmelt furnace, which is equipped with a first through hole for installing the side-blowing lance water jacket, and a second through hole for fixing the high-temperature lance. This improves the metal recovery rate and smelting efficiency, and the side-blowing lance water jacket further protects the high-temperature lance in the tuyeres area. The second toothed water jacket has a notch for slag discharge, which facilitates the discharge of slag from the Ausmelt furnace. The first and second toothed water jackets can be spliced to form a closed furnace body cooling structure for the Ausmelt furnace. Since cooling pipes are pre-embedded in the first and second toothed water jackets, a large amount of heat is carried away from the furnace body refractory material by transporting circulating coolant, and the cooling and heat dissipation are more uniform, thereby reducing the erosion of the furnace body refractory material by high-temperature melt and thermal erosion, and improving the service life of the Ausmelt furnace.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.
[0026] Please see Figures 1 to 13 This embodiment provides an oxygen-enriched side-blown furnace body cooling combined cast copper water jacket 100 for an Osmite furnace. The combined cast copper water jacket 100 includes a first toothed water jacket 10, a second toothed water jacket 20, and a side-blown gun water jacket 30. For ease of description, the height direction of the first toothed water jacket 10 and the second toothed water jacket 20 is defined as the first direction X, and the width direction of the first toothed water jacket 10 and the second toothed water jacket 20 is defined as the second direction Y. The first direction X and the second direction Y are perpendicular to each other. The first toothed water jacket 10 has a first through hole 11 through it along the thickness direction. The first through hole 11 can be set at the middle position of the first toothed water jacket 10 so that the high-temperature spray gun 200 can spray out fuel with a high oxygen concentration after installation, thereby improving the metal recovery rate and smelting efficiency. Several first cooling pipes 12 are pre-embedded in the first toothed water jacket 10. Multiple first cooling pipes 12 can be set, and the multiple first cooling pipes 12 can be set in a U-shape or a serpentine shape to achieve uniform heat dissipation of the first toothed water jacket 10.
[0027] Furthermore, in combination Figures 7 to 13 The second toothed water jacket 20 is provided with a notch 21 for slag discharge, and several second cooling pipes 22 are pre-embedded in the second toothed water jacket 20. The notch 21 is arranged through the thickness direction of the second toothed water jacket 20. Several first toothed water jackets 10 and several second toothed water jackets 20 are spliced together to form the furnace cooling structure of the Osmite furnace. Specifically, the first toothed water jacket 10 and the second toothed water jacket 20 can be spliced together on the end faces on both sides of the second direction Y. The splicing method can be achieved by setting irregular surfaces that fit each other on the first toothed water jacket 10 and the second toothed water jacket 20. The side blow gun water jacket 30 is detachably connected to the first through hole 11. The side blow gun water jacket 30 is provided with a second through hole 31 for fixing the high temperature spray gun 200, and several third cooling pipes 32 are pre-embedded in the side blow gun water jacket 30 near the second through hole 31.
[0028] It should be noted that the second toothed water jacket 20 is set with the same height and width as the first toothed water jacket 10. In this embodiment, the furnace body structure formed by splicing the second toothed water jacket 20 and the first toothed water jacket 10 is annular. Of course, in some examples, they can also be spliced to form other shapes, such as polygons. At the same time, the first toothed water jacket 10 can be spliced with the first toothed water jacket 10, and the second toothed water jacket 20 can be spliced with the second toothed water jacket 20. The specific number of the second toothed water jacket 20 and the first toothed water jacket 10 can be selected according to actual needs. In this embodiment, the first toothed water jacket 10 can be set to 12 pieces, and the second toothed water jacket 20 can be set to 4 pieces. Among them, the splicing of two second toothed water jackets 20 forms the slag discharge port at the notch 21.
[0029] It should also be noted that there is currently limited research in the industry on side-blown Osmite furnaces. The combined cast copper water jacket 100 in this embodiment can be used not only for side-blown Osmite furnaces, but also for Osmite furnaces combining side-blown and top-blown types. In addition, the combined cast copper water jacket 100 in this embodiment can form the furnace body of the Osmite furnace with refractory material. The refractory material and the combined cast copper water jacket 100 can be fixed by bolts. The connection between the side-blown lance water jacket 30 and the first toothed water jacket 10 can be an interference fit connection in the form of a snap-fit. At the same time, the first toothed water jacket 10, the second toothed water jacket 20 and the side-blown lance water jacket 30 are made of pure copper material. The first cooling pipe 12, the second cooling pipe 22 and the third cooling pipe 32 are respectively formed by pre-embedded pure copper pipes inside the first toothed water jacket 10, the second toothed water jacket 20 and the side-blown lance water jacket 30. In this way, the heat dissipation and cooling performance are better while ensuring the structural strength of the water jacket.
[0030] The combined cast copper water jacket 100 provided in this application, through the arrangement of a first toothed water jacket 10, a second toothed water jacket 20, and a side-blowing lance water jacket 30, wherein the first toothed water jacket 10 is provided with a first through hole 11 for mounting the side-blowing lance water jacket 30, and the side-blowing lance water jacket 30 is provided with a second through hole 31 for fixing the high-temperature spray lance 200, the first toothed water jacket 10 and the second toothed water jacket 20 are spliced to form the furnace body cooling structure of the Osmelt furnace, realizing efficient cooling of the furnace body of the Osmelt furnace with side blowing or a combination of side blowing and top blowing, improving the metal recovery rate and smelting efficiency, and the arrangement of the side-blowing lance water jacket 30 To further protect the high-temperature spray gun 200 in the tuyeres area, the second toothed water jacket 20 is provided with a notch 21 for slag discharge, which facilitates the discharge of slag from the Osmite furnace. The first toothed water jacket 10 and the second toothed water jacket 20 can be spliced together to form a closed furnace cooling structure for the Osmite furnace. Since cooling pipes are pre-embedded in the first toothed water jacket 10 and the second toothed water jacket 20, a large amount of heat is carried away from the furnace body refractory material by transporting circulating coolant, and the cooling and heat dissipation are more uniform, thereby reducing the erosion of the furnace body refractory material by high-temperature melt and thermal erosion, and improving the service life of the Osmite furnace.
[0031] Please see Figures 2 to 5 In some embodiments, multiple first cooling pipes 12 are pre-embedded in the first toothed water jacket 10 and staggered from the first through hole 11. The first cooling pipes 12 are respectively provided with a first water inlet head 121 and a first water outlet head 122 at both ends. The first water inlet head 121 and the first water outlet head 122 extend outward from the same side end face of the first toothed water jacket 10. Specifically, the first through hole 11 is provided in the middle area of the first toothed water jacket 10. In this embodiment, three first cooling pipes 12 can be provided. The first cooling pipes 12 are arranged along the first direction X and are arranged in a U-shape. The first water inlet head 121 and the first water outlet head 122 extend to the outer end face of the first toothed water jacket 10 and are close to the top of the first toothed water jacket 10. At the same time, the first cooling pipes 12 can be copper pipes. This arrangement facilitates the connection of the first cooling pipes 12 with the external coolant delivery pipes and makes the cooling effect in the first toothed water jacket 10 more uniform.
[0032] Please see Figures 7 to 10In some embodiments, the notch 21 is located near the bottom of the second toothed water jacket 20. Multiple second cooling pipes 22 are embedded in the second toothed water jacket 20 and are staggered from the notch 21. The two ends of the second cooling pipes 22 are respectively provided with a second inlet pipe 221 and a second outlet pipe 222. The second inlet pipe 221 and the second outlet pipe 222 extend outward from the same side end of the second toothed water jacket 20. The notch 21 facilitates the discharge of slag. The notch 21 can be set as a rectangular notch. At the same time, the notch 21 is staggered from the second cooling pipes 22. Similar to the first toothed water jacket 10, the second inlet pipe 221 and the second outlet pipe 222 of the second toothed water jacket 20 extend to the outer end face of the second toothed water jacket 20 and are both close to the top of the second toothed water jacket 20. This arrangement facilitates the connection of the second cooling pipes 22 with the external coolant delivery pipes and makes the cooling effect in the second toothed water jacket 20 more uniform.
[0033] Please see Figure 6 In some embodiments, the heating surfaces of the first toothed water jacket 10 and the second toothed water jacket 20 are respectively provided with slag-hanging grooves 13. Multiple slag-hanging grooves 13 are spaced apart along the first direction X on the heating surfaces. Each slag-hanging groove 13 on the first toothed water jacket 10 and the second toothed water jacket 20 is arranged along the second direction Y. The shape and outline of the slag-hanging groove 13 can be set as rectangular. At the same time, multiple slag-hanging grooves 13 are spaced apart along the first direction X. The arrangement of the slag-hanging grooves 13 can make the heating surfaces of the first toothed water jacket 10 and the second toothed water jacket 20 form a slag skin layer, thereby better protecting the cooling water jacket.
[0034] Please see Figures 2 to 10 In some embodiments, the two end faces of the first toothed water jacket 10 are respectively provided with a first connecting portion, and the two end faces of the second toothed water jacket 20 are respectively provided with a second connecting portion connected to the first connecting portion. The arc segments formed by the projection of the heating surfaces of the first toothed water jacket 10 and the second toothed water jacket 20 along the first direction X have the same arc radius. The heating surface is the end face close to the inside of the Osmite furnace. It should be noted that the first connecting portion of the first toothed water jacket 10 and the second connecting portion of the second toothed water jacket 20 are provided on both sides along the second direction Y. The splicing structure of the first connecting portion and the second connecting portion can be respectively provided with complementary stepped shapes on the end faces of the first toothed water jacket 10 and the second toothed water jacket 20. The projection of the first toothed water jacket 10 and the second toothed water jacket 20 along the first direction X is an arc shape, and the arc radius of the arc shape is the same, so that the first toothed water jacket 10 and the second toothed water jacket 20 are spliced to form a complete ring.
[0035] Optionally, multiple screw holes 14 can be provided on the surfaces of the first toothed water jacket 10 and the second toothed water jacket 20, and the screw holes 14 are staggered from the first cooling pipe 12 or the second cooling pipe 22. The provision of multiple screw holes 14 facilitates the connection and fixation of the first toothed water jacket 10 and the second toothed water jacket 20 with the refractory material.
[0036] Please see Figures 11 to 13 In some embodiments, the side-blowing lance water jacket 30 is provided with a weld overlay wear-resistant layer 33 near the heated surface inside the furnace. The weld overlay wear-resistant layer 33 completely covers the heated surface. Specifically, the weld overlay wear-resistant layer 33 can be a weld overlay wear-resistant alloy plate. Since the weld overlay wear-resistant layer 33 completely covers the heated surface of the side-blowing lance water jacket 30, the side-blowing lance water jacket 30 is further protected by the weld overlay wear-resistant layer 33 because the thermal erosion and chemical corrosion inside the furnace are more severe at the side-blowing lance water jacket 30. At the same time, the second through hole 31 provided inside the side-blowing lance water jacket 30 can be inclined. Specifically, it is inclined downward from the outer end face to the heated surface. In this way, when the high-temperature spray gun 200 is installed on the side-blowing lance water jacket 30, on the one hand, the stability of the high-temperature spray gun 200 after installation is ensured, and on the other hand, the nozzle of the high-temperature spray gun 200 is inclined downward towards the furnace, which more effectively promotes the stirring and heat and mass transfer process in the molten pool, and improves the metal recovery rate and smelting efficiency of the Osmelt furnace.
[0037] Please see Figure 14 This embodiment provides an Osmite furnace. The Osmite furnace 1000 includes the oxygen-enriched side-blown furnace body cooling combined cast copper water jacket 100 provided in any of the above embodiments. Specifically, refractory bricks 300 and other refractory materials can be laid at the bottom of the Osmite furnace 1000. The combined cast copper water jacket 100 forms the side wall cooling structure of the Osmite furnace to achieve efficient cooling of the furnace body.
