Description

1 TARIFF REFRACTOR FOR CONTAINERS EXPOSED TO MOLTEN MATERIALS LAYER STRUCTURES AND ASSEMBLY Invention Area 5

[0001] The present invention relates generally to vessels exposed to molten materials and More specifically, materials included in such containers to protect against molten materials. It deals with refractory sheet structures and assemblies. State of the Invention 10

[0002] Various types of containers have been developed for handling molten material. These types of containers Examples include steel crucibles, iron crucibles, electric arc furnaces, high-speed basic oxygen furnaces, and Glass tanks can be provided. Refractory materials are used to protect the bottoms of these containers from molten material. Layers of material are placed.

[0003] The base of such containers typically has at least one layer of safety liner and at least one layer of 15 It is common practice for the working primer to consist of individual layers, brick or front. They can be formed from pre-shaped refractory shapes, such as cast shapes, or from refractory materials. It can be formed in situ from a monolithic refractory material such as cast or dry vibrating material. Smaller brick shapes have rectangular geometries, while larger precast shapes They are sized to match the geometry specific to the base of the containers. 20

[0004] However, the service life of the vessels in which the above-mentioned structures are used. throughout, leading to leakage of molten material and potentially perforation of the container. Structural defects may exist. For example, additional safety plates may be added to the bottoms of the containers. The main reason for adding layers is the standard layout which has numerous joints containing straight paths. It involves forming bases from brick shapes; this is where the molten material comes into contact with these 25 This creates the potential for penetration through the joints. Additional safety base layers collect the liquid material. and acts as a puncture-resistant layer in the container.

[0005] Also, thermal changes that occur during temperature variations at the bottom of the container During the cycle, the bricks may loosen during cooling, which can then melt during heating. This can lead to the potential for the material to float upwards through the interior. Upwards 30 Buoyancy is the effect of a significant difference between the density of the refractory material and the density of the molten metal. This is the result. For example, the density of refractory material is typically less than 200 lb / ft³; in contrast, that of steel. 2 Its density is 490 lb / ft³, compared to 555 lb / ft³ for copper and approximately 700 lb / ft³ for lead. This is its buoyancy. This incident raises a security concern and is a common problem for which a solution is being sought. Standard When pressed profiles are incorrectly assembled or have geometric design flaws, This buoyancy can occur randomly.

[0006] Working layers formed from large precast elements or in-situ 5 working layers created by casting, working layers created from bricks It is simpler than that. In particular, bricks are often used to create working layers. They need to be joined together. On the other hand, the work is made up of large precast elements. generally for working layers created by layering or in-situ casting No merging process is required. However, working layers of large precast elements are 10. To create or form working layers by in-situ casting, mixers and specialized equipment for material preparation such as pumps, or cranes or hoists. Material handling equipment is required. Large-scale construction of such sub-layers, in other words This can lead to the formation of large heat-induced stresses in the layers; this can affect the container. This leads to more frequent occurrence of cracks and structural defects throughout its service life. 15 These defects, as is similarly seen in brickmaking, lead to the leakage of molten material. and could potentially lead to a puncture in the container.

[0007] Alternatively, thinly sintered during initial exposure to heat and molten metal. Dry materials that form solid layers are used in the construction of the underlying working layers. A thin layer of 20 sintered material is formed on top of a dry working layer by the effect of heat. solid layers allow the dry material to remain in place after being exposed to the molten material. It forms the only locking mechanism that provides this. If these layers do not form properly, The entire monolithic dry material may surface during service, which could potentially This can lead to catastrophic leaks from the container due to the molten material.

[0008] This invention is designed to overcome these disadvantages in traditional methods. 25 It has been designed. Summary of the Invention

[0032] Now, solely for the purpose of demonstrating a preferred application of the invention, and this 20 not for the purpose of limiting, but by referring to the shapes, the various applications of the invention It will be explained.

[0033] For the purposes of this explanation, mosaic patterns are made of interconnected elements geometric shapes with angles or curves, without any gaps or overlaps 25 as the repetition of a three-dimensional layer structure to completely cover it without any repetition. It is defined.

[0034] Figures 1-8 show examples of the refractory layer structure (2) according to an application of the invention. These are perspective views showing the refractory layer structure (2) in Figure 1-3, to each other. It includes a layer (4) consisting of refractory blocks (10 and 12) locked in a mosaic pattern. Refractory blocks (10 and 12) are 30, shown in Figure 4 and discussed in more detail below. The first mosaic is positioned in the refractory block pattern (8). Refractory blocks (10 and 12), 6 It can be formed from various combinations of magnesium, carbon, and alumina, and can be used for hydraulic or They can be shaped by isostatic pressing. Related refractories also include Magnesia-Carbon, classified as Alumina-Magnesia-Carbon or Magnesia-Alumina-Carbon products It is known.

[0035] Interlocking refractory blocks (10 and 12) are joined in a mosaic pattern by means of a binder. They can be bonded together. The binding agent used may include, but is not limited to, one or more of these. It may contain more organic, phosphate, or thermosetting adhesives or mortars. (See Figures 2 and 3) As shown, interlocking refractory blocks (10 and 12), one or more fixing bands (6) They can also be fixed together in a mosaic pattern by means of fixing tapes (6), interlocking refractory To fix the blocks (10 and 12) in the mosaic pattern, the layer formed by these blocks (4) 10 They can be positioned along the perimeter. Fixing straps (6), steel or heavy duty It can be manufactured from, but is not limited to, polypropylene or polyester plastic. Fastening to fix and join the strips (6), interlocking refractory blocks (10 and 12) in a mosaic pattern It can also be used in conjunction with a binding agent.

[0036] In addition, as shown in Figures 2 and 3, the total of 15 interlocking refractory blocks (10 and 12) Depending on the length and surface area of ​​the layer (4) of interlocking refractory blocks (10 and 12), Multiple fixing straps (6) can be used as required by the situation. In one example, locked When the total length of refractory blocks (10 and 12) exceeds nine inches, more than one Fixing tape (6) may be required. In another example, interlocking refractory blocks (10 and 12) If the surface area of ​​the layer (4) is 25 ft² or less, more than one fixing tape (6) 20 It may not be necessary. However, the layer consisting of interlocking refractory blocks (10 and 12) (4) If the surface area is between 25 ft² and 49 ft², two fixing strips (6) may be required. Also, lockable If the surface area of ​​the layer (4) of refractory blocks (10 and 12) is 49 ft² or more, then one Additional fixing tape (6) may be required.

[0037] As shown in Figure 4, refractory blocks (10) are 25 from their bottom to their top. In other words, they are primary block structures that expand from their bases to their apexes. Refractory blocks. (12) narrows from its bottom to its top, that is, from its base to its apex. They are the second block structures. Refractory blocks (10 and 12), interlocking refractory blocks (10 and 12) In order for the layer (4) to be continuous, they must be adjacent to each other and in contact with each other. They are arranged. Refractory blocks (10 and 12) are positioned opposite each other at corresponding angles or 30° 7 It has curvatures. Each of the refractory blocks (10) and each of the refractory blocks (12) has one or It is in contact with more adjacent refractory blocks (10).

[0038] The first mosaic containing interlocking refractory blocks (10 and 12) as shown in Figures 1-3. Although it has been shown that the refractory block arrangement (8) forms the layer (4), here The applications described are not limited to this. Figures 5 and 6 show interlocking refractory blocks (34 and 36) 5 Figures 7 and 8 show the second mosaic refractory block arrangement (32) containing interlocking refractories. It shows the third mosaic refractory block arrangement (56) containing blocks (58 and 60). Depending on the needs of the application, the second mosaic block layout may be used instead of the first mosaic block layout (8). Refractory block layout (32) and third mosaic refractory block layout (56) can be used.

[0039] As shown in Figures 5 and 6, refractory blocks (34) are 10 from their bottom to the top. They are first-block structures that expand in sections, that is, from their bases to their apex. Refractory blocks (36) are formed from their bottoms to their tops, that is, from their bases to their tops. They are the second block structures that narrow towards the points. Refractory blocks (34 and 36), second mosaic When constructed according to the refractory block layout (32), it consists of interlocking refractory blocks (34 and 36). The layers (4) shall be continuous, adjacent to each other and in contact with each other respectively. They are arranged. Refractory blocks (34 and 36) have opposite angles to each other. The refractory blocks (34) each of the refractory blocks (36) and one or more adjacent refractory blocks (34) is in contact with.

[0040] As shown in Figures 7 and 8, refractory blocks (58) are the first block structures. Refractory blocks (60) are the second block structures. Refractory blocks (58 and 60) are the second mosaic 20 When constructed according to the refractory block pattern (56), interlocking refractory blocks (58 and 60) The layer (4) formed will be continuous, successively adjacent to each other and in contact They are arranged in the following way. Refractory blocks (58 and 60) correspond to each other in opposite directions. It has curvatures. Each of the refractory blocks (58) and each of the refractory blocks (60) has one or It is in contact with more adjacent refractory blocks (58). 25

[0041] Also, as long as the refractory blocks of the layer (4) are locked in a mosaic pattern, mosaic refractory block pattern for layer (4) of any two refractory block designs It is anticipated that they can be used. In particular, refractory blocks (10 and 12), refractory blocks (34 and 36) or any two blocks such as refractory blocks (58 and 60), gaps or overlaps They must be geometrically complementary to form the layer (4) without. Refractory 30 blocks (10 and 12), refractory blocks (34 and 36) and angled refractory blocks (58 and 60) 8 The curved edges cut off a direct path for molten material to penetrate and the molten material more evenly distributed the expansion stresses caused by the materials across the layer (4) It is used to distribute. The precise geometry of the mosaic pattern is for the layer (4) in a particular application. This can be determined based on the projected or calculated total voltage.

[0042] Figures 9-11, furnace refractory layer structure (62) 5 according to an application of the invention. These are perspective views showing examples of the furnace refractory layer structure (62), mosaic. It contains a layer (64) consisting of interlocking refractory blocks (70 and 72) in its pattern. Interlocking refractory blocks (70 and 72) are shown in Figures 10 and 11 and are detailed below. The oven mosaic is positioned within the refractory block pattern (68).

[0043] Interlocking blocks (70 and 72), a binding agent in mosaic pattern 10 They can be linked together by means of: The binding agent used, including but not limited to, It may contain one or more organic, phosphate, or thermosetting adhesives or mortars. Although not shown here, the interlocking refractory blocks (70 and 72) form a mosaic pattern. or they can be fastened together by means of more fastening tapes (6). Fastening To fix the strips (6), interlocking refractory blocks (70 and 72) in the mosaic pattern, these blocks 15 The fixing tapes (6) can be positioned along the perimeter of the layer (64) that it forms. or they can be manufactured from heavy-duty polypropylene or polyester plastic, but these It is not limited. The fixing tape (6) locks the refractory blocks (70 and 72) in a mosaic pattern. It can also be used with a binder to secure and join the material.

[0044] Also, similar to the representation of the fixing tapes (6) in Figures 2 and 3, the locked 20 the total length of the refractory blocks (70 and 72) and the surface of the layer of these blocks (64) Depending on the area, multiple fixing tapes may be used as required by the situation (6) Available. Interlocking refractory blocks (70 and 72) have a total length of up to 37 inches. They may be and therefore need to be secured with more than one fixing band (6). Other In one example, the surface area of ​​a layer (64) of interlocking refractory blocks (70 and 72) is 25 ft² or more. If there are few, more than one fixing tape (6) may not be required. However, the locked tape at the address If the surface area of ​​the layer (4) of refractory blocks (10 and 12) is between 25 ft² and 49 ft², then two Fixing tape (6) may be required. Also, the layer consisting of interlocking refractory blocks (10 and 12) (4) If the surface area is 49 ft² or more, more than one fixing strip (6) may be required.

[0045] As shown in Figures 10 and 11, refractory blocks (70) are 30 inches from the bottom to the top. They are first-block structures that expand in sections, that is, from their bases to their apex. 9 Refractory blocks (72) are formed from their bottoms to their tops, that is, from their bases to their tops. They are the second block structures that narrow towards the points. Refractory blocks (70 and 72), respectively. They are arranged adjacent to each other and in contact with each other. Refractory blocks (70 and 72), They have opposite angles; however, similar to the subject shown in Figure 7, they are in harmony with each other. They can also be designed with opposite curvatures. Each of the refractory blocks (70) and refractory 5 Each of the blocks (72) is in contact with one or more adjacent refractory blocks (70).

[0046] As shown in Figures 9-11, from interlocking refractory blocks (70 and 72) The resulting layer (64) also contains one or more holes (66) formed within it. The holes (66) each by two refractory blocks (70) and two refractory blocks (72) The holes (66) are defined as follows: 10 perpendicular to the top and bottom faces of the interlocking refractory blocks (70 and 72). It has been created.

[0047] The furnace refractory layer structure (62) consists only of interlocking refractory blocks in Figure 9. Although the layer (64) consisting of (70 and 72) is shown to include the furnace refractory The layer structure (62) consists of a series of stacked layers of interlocking refractory blocks (70 and 72). (64) is expected to be included. This situation is shown in Figure 14 with the basic oxygen furnace (108) and 15 This is shown in relation to and discussed in more detail below, with reference to Figure 14. will be taken. In addition, the furnace refractory layer, shown as a rectangular arrangement in Figure 9. (62) Despite its structure, the applications described herein are not limited to this; because the oven The refractory layer structure (62) may have any other geometric configuration. For example, in terms of the basic oxygen furnace (108) shown in Figure 14, the furnace refractory layer 20 It is more likely that its structure (62) is a cylindrical arrangement.

[0048] In addition, the furnace refractory layer structure (62) is the furnace mosaic as shown in Figures 9-11. Although it has a refractory block pattern (68), the pattern (68) is only one of many predicted patterns. It is one of them, and the applications described here are not limited to it. For example, bakery mosaic. refractory block pattern (68), mosaic of refractory blocks and refractory block layer 25 It can be any refractory block pattern that allows for the presence of holes within it.

[0049] Figures 12 and 13 show an example of a refractory vessel (92) used to hold molten materials. It shows. Refractory door (92), metal shell (94), bottom safety liner (102), refractory side It includes a wall (96), refractory layer structure (2) and refractory outer ring assembly (104). Molten materials, refractory side wall (96), refractory layer structure (2) and refractory outer ring 30 It is kept in an area of ​​the refractory vessel (92) defined by the setup (104).

[0050] The metal shell (94) forms the outer frame of the refractory container (92). Bottom safety The lower safety liner (102) is located on the inner lower surface of the metal shell (94). (102), molten materials kept in refractory vessel (92) to the base of metal shell (94) It is made of refractory materials to prevent damage. Refractory side wall (96), It is placed on the lower safety lining (102) and the inner side surface of the metal shell (94). 5 The refractory side wall (96) includes wall safety lining (98) and working lining (100). Both walls both the safety lining (98) and the working lining (100) damage the inner side surface of the metal shell (94). It is made of refractory materials to prevent him from seeing. Working liner (100), refractory It can be made from blocks or bricks.

[0051] For illustrative purposes, refractory layer structure (2), first mosaic refractory block 10 in accordance with layer (4) consisting of interlocking refractory blocks (10 and 12) belonging to pattern (8) As shown. Therefore, interlocking refractory bricks (10 and 12) form the first mosaic in Figures 1-4. all the properties and elements previously described regarding the refractory block pattern (8) It has. However, as previously stated, layer (4) has the first mosaic refractory block pattern. Instead of the interlocking refractory blocks (10 and 12) belonging to (8), 15 belonging to the second mosaic refractory block pattern (32) interlocking refractory blocks (34 and 36) or interlocking blocks belonging to the third mosaic refractory block pattern (56) It may contain refractory blocks (58 and 60). In addition, the refractory blocks in the layer (4) form a mosaic. As long as they are interlocked in the pattern, any two refractory block designs for layer (4) It is anticipated that it can be used as a mosaic refractory block pattern. Furthermore, the first mosaic... If used instead of refractory block pattern (8), interlocking refractory blocks (34 and 36) and 20 Interlocking refractory blocks (58 and 60), the second mosaic refractory block pattern in Figures 5 and 6, respectively. (32) and with regard to the third mosaic refractory block pattern in Figures 7 and 8 (56), we previously discussed It possesses all the features and elements described.

Refractory exterior The ring arrangement (104) may be in contact with the refractory layer structure (2). Also, previously Locked refractory blocks (10 and 12) with a binder or one or more fasteners 30 by means of the tape (6) they can be connected or fixed to each other in the mosaic pattern Although it has been stated, the refractory outer ring assembly (104) is in contact with the refractory layer structure (2). 11 It can hold interlocking refractory blocks (10 and 12) in a mosaic pattern and melt to prevent the formation of voids that could lead to the material creating a passage. It can help to hold the refractory layer structure (2) inside the refractory vessel (92). In addition, refractory outer ring assembly (104), a binder or one or more fixing bands (6) The relevant connection of locked refractory blocks (10 and 12) performed by or 5 Once fixed, it also performs the function of holding the interlocking refractory blocks (10 and 12). It is anticipated that this could bring about.

[0053] In an example of the construction of a refractory vessel (92), the refractory layer structure (2), The refractory layer structure (2) is formed before it is placed inside the refractory vessel (92). Its creation involves interlocking refractory blocks (10 and 12) in a mosaic pattern. 10 The refractory blocks (10 and 12) are interlocked outside the refractory container (92) using a binder. This is achieved by applying the material or one or more fixing tapes (6). Then, the formed refractory layer structure (2), the refractory outer ring arrangement (104) Layer (4) consisting of refractory blocks (10 and 12) locked with refractory side wall (96) It is positioned on the lower safety liner (102) to be placed in the gap between them. 15 Refractory outer ring assembly (104), refractory side wall (96) and interlocking refractory blocks (10 When positioned between the layers formed (12), the refractory outer ring assembly (104), to hold the shaped refractory layer structure (2) inside the refractory vessel (92) and molten Locked refractory to prevent the formation of voids through which the material can pass. You can hold blocks (10 and 12) in a mosaic pattern. 20

Refractory blocks (72) are formed from the bottom to the top, that is They are second block structures that narrow from their bases to their apex. In each layer (64) Refractory blocks (70 and 72), refractory blocks (70 and 72) interlocked in a mosaic pattern of 20 They are arranged in a way that they interlock, successively adjacent to each other and in contact with each other.

[0059] It should be noted again that the furnace refractory layer structure (62) is as shown in Figures 9-11. Although the oven has a mosaic refractory block pattern (68), the pattern (68) is one of the many predicted This is just one example of a pattern, and the applications described here are not limited to it. For instance, oven mosaic refractory block pattern (68), both mosaicing of refractory blocks and 25 Any refractory block that allows holes to be present within the refractory block layer.
