Description

Technical Field

[0001] This utility model relates to the field of continuous casting equipment manufacturing technology, and in particular to a V-shaped slag retaining wall casting mold. Background Technology

[0002] The slag retaining wall in the tundish plays a crucial role in steelmaking. In continuous casting, it prevents slag from flowing into the molten steel, causing inclusions in the molten steel to float to the surface, thus removing them and improving the cleanliness of the steel. Slag retaining walls are typically made from high-alumina or alumina-magnesia refractory materials and produced through casting.

[0003] For example, the utility model patent document with authorization announcement number CN2744441Y discloses a tundish slag retaining wall and its construction mold. In its technical solution, the tundish slag retaining wall is shaped like a "7" and is embedded in the working layer on the tundish shell. The plate surface has flow holes. The construction mold consists of two components: one component is shaped like a "7" consistent with the slag retaining wall, and the other component is a straight plate symmetrically located on both sides of the component and matched with it. This utility model's technical solution can only be used to produce "7" shaped slag retaining walls. Furthermore, because the construction mold needs to be built directly inside the tundish, the construction space is limited, and the operation is relatively inconvenient. When disassembling the mold, it is necessary to lift both mold components out of the tundish as a whole, which is also quite troublesome and will affect the production efficiency of the slag retaining wall. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a V-shaped slag retaining wall casting mold that is easy to assemble and disassemble and can effectively improve the continuous production efficiency of slag retaining walls.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a V-shaped slag retaining wall casting mold, including a fixed frame, the fixed frame including a horizontally arranged base plate and a middle partition plate vertically fixed in the middle of the base plate, and a set of casting templates detachably connected to the fixed frame are respectively arranged on both sides of the middle partition plate; the casting template includes a vertical plate arranged parallel to the middle partition plate, a bottom pad plate and two side pad plates clamped between the vertical plate and the middle partition plate, the bottom pad plate is located at the bottom of the casting template, and the bottom of the two side pad plates abuts against the two ends of the bottom pad plate respectively, and the side pad plates and the bottom pad plate form an obtuse angle.

[0006] As a further improvement to the above solution: multiple fixing rods are vertically connected to the partition plate, the partition plate is provided with fixing holes corresponding to the fixing rods, and the vertical plate is provided with connecting holes corresponding to the fixing holes; the fixing rods pass through the corresponding fixing holes, and the two ends of the fixing rods pass through the corresponding connecting holes on the two vertical plates respectively; the bottom pad plate and the side pad plate abut against the fixing rods, and the fixing rods form a limiting fit on the bottom pad plate and the side pad plate from the outside of the casting template.

[0007] As a further improvement to the above solution: both ends of the fixing rod are provided with external thread sections, and a limiting fit is formed on the vertical plate from the outside of the casting template by fixing bolts that are threadedly engaged with the external thread sections.

[0008] As a further improvement to the above solution, a limiting pin is also included, which is fixed to the top fixing rod. The limiting pin is vertically fixed to the corresponding fixing rod and forms a limiting fit with the vertical plate from the inside of the casting mold.

[0009] As a further improvement to the above scheme, it also includes a steel flow hole mold; the middle part of the partition plate is provided with a mold insertion port, and the vertical plate is provided with a mold through hole that is directly opposite to the mold insertion port; one end of the steel flow hole mold passes through the mold through hole on the vertical plate and is inserted into the mold insertion port on the partition plate, and the other end of the steel flow hole mold is located outside the casting mold.

[0010] As a further improvement to the above scheme: the steel flow hole mold is a circular wedge mold, the diameter of the mold insertion port is smaller than the diameter of the mold through hole, and the small end of the steel flow hole mold is inserted into the mold insertion port.

[0011] The beneficial effects of this utility model are as follows: This utility model installs the casting template by setting a fixed frame. The vertical plate and the middle partition plate in the fixed frame limit the bottom pad plate and the side pad plate to form a set of casting templates on both sides of the fixed frame. After placing each pad plate in the corresponding position, the casting template can be assembled and fixed by simply locking the vertical plate. After the casting is completed, the casting mold can be disassembled by simply moving the vertical plate outward. The disassembly and assembly process of the casting mold is quick and efficient, thereby effectively improving the casting production efficiency of V-shaped slag retaining walls and enabling the continuous production of V-shaped slag retaining walls.

[0015] To facilitate understanding of this utility model, the following description, in conjunction with the accompanying drawings, will provide further details.

[0016] In the description of this utility model, it should be noted that the terms "front", "rear", "left", "right", "up", "down", "inner", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of description and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] like Figure 1 As shown, the V-shaped slag retaining wall casting mold disclosed in this utility model consists of a fixed frame and casting templates. A set of casting templates is provided on each side of the fixed frame, allowing two V-shaped slag retaining walls to be cast simultaneously using the two sets of casting templates. This utility model uses an assembly method to assemble the casting templates, and the casting templates are fixed by clamping them with the fixed frame. Therefore, the assembly and disassembly of the casting templates is relatively simple and can be performed quickly.

[0018] Specifically, such as Figure 1 As shown, the fixing frame in this utility model includes a base plate 100 and a middle partition plate 200. The base plate 100 is placed horizontally as the base of the entire V-shaped slag retaining wall casting mold, and the middle partition plate 200 is vertically fixed in the middle of the base plate 100; a set of casting templates detachably connected to the fixing frame are respectively set on the left and right sides of the middle partition plate 200. The casting template includes a vertical plate 300, a bottom pad plate 400, and a side pad plate 500. A vertical plate 300 is set on each side of the middle partition plate 200, and the vertical plate 300 is parallel to the middle partition plate 200. The vertical plate 300 can be translated relative to the middle partition plate 200; the bottom pad plate 400 and the side pad plate 500 are set between the vertical plate 300 and the middle partition plate 200, and both the bottom pad plate 400 and the side pad plate 500 are vertically set between the vertical plate 300 and the middle partition plate 200, and as shown... Figure 3 As shown, the bottoms of the two side pads 500 abut against the two ends of the bottom pad 400, and an obtuse angle is formed between the side pads 500 and the bottom pad 400. The gap between the vertical plate 300 and the middle partition plate 200 is adjusted by translating the vertical plate 300, so that the bottom pad 400 and the side pads 500 can be clamped between the vertical plate 300 and the middle partition plate 200. The middle partition plate 200, the vertical plate 300, the bottom pad 400 and the side pads 500 together form a casting template for a V-shaped slag retaining wall. The unclosed top opening of the casting template serves as the casting port. After casting with refractory material, a V-shaped slag retaining wall with a flat bottom is formed.

[0019] Furthermore, in this utility model, the assembly of the casting template is achieved by setting a fixing rod 600 on the middle partition 200 to limit the bottom pad 400 and the side pad 500. For example... Figure 2 As shown, a plurality of fixing holes 210 are provided on the partition plate 200. Since this utility model is used for casting a V-shaped slag retaining wall, the fixing holes 210 are arranged in a V-shape on the partition plate 200, for example... Figure 2 The partition plate 200 has 7 fixing holes 210, 3 fixing holes 210 are arranged horizontally at the bottom of the partition plate 200, and 2 fixing holes 210 are provided on each side of the partition plate 200. The fixing holes 210 on the sides and the fixing holes 210 at the bottom ends are connected to form an oblique line. Fixing rods 600, corresponding one-to-one with fixing holes 210, are fixed on the partition plate 200, and connecting holes, corresponding one-to-one with fixing holes 210, are provided on the vertical plate 300. The fixing rods 600 are perpendicular to the partition plate 200 and pass through the corresponding fixing holes 210, and the two ends of the fixing rods 600 pass through the connecting holes on the two vertical plates 300 respectively. The fixing rods 600 can be welded to the partition plate 200. Then, the bottom pad plate 400 is placed on the fixing rods 600 at the bottom, and the side pad plates 500 abut against the fixing rods 600 on both sides. The fixing rods 600 limit the bottom pad plate 400 and the side pad plate 500 from the outside of the casting template. The bottom pad plate 400 and the side pad plate 500 are clamped by translating the vertical plate 300, thus forming two sets of casting templates on both sides of the partition plate 200.

[0020] Furthermore, such as Figure 1 As shown, to enhance the stability of the casting mold after assembly, this invention sets both ends of the fixing rod 600 as external threaded sections. After the two ends of the fixing rod 600 pass through the corresponding connecting holes on the two vertical plates 300, fixing bolts 610 are installed on the external threaded sections of the fixing rod 600. The locking action of the fixing bolts 610 forms a limiting fit with the vertical plate 300 from the outside of the casting mold, pressing the vertical plate 300 against the bottom pad 400 and the side pad 500. In addition, a limiting pin 620 can be set on the fixing rod 600 at the top. The limiting pin 620 is vertically fixed to the fixing rod 600, and forms a limiting fit with the vertical plate 300 from the inside of the casting mold.

[0021] Since flow holes are needed in the slag retaining wall to allow the cleaned molten steel to drain out, the conventional approach is to drill these holes after the slag retaining wall has been cast. This invention aims to achieve one-time forming of the V-shaped slag retaining wall, saving subsequent drilling steps. Figure 1As shown, a steel flow hole mold 700 is also provided for the casting template to form steel flow holes in the V-shaped slag retaining wall. Specifically, the steel flow hole mold 700 is a circular wedge-shaped mold with a large end and a small end. A mold insertion port 220 is provided in the middle of the partition plate 200, and a mold through hole is provided on the vertical plate 300, which is directly opposite to the mold insertion port 220. The diameter of the mold insertion port 220 is smaller than the diameter of the mold through hole. The small end of the steel flow hole mold 700 passes through the mold through hole on the vertical plate 300 and is inserted into the mold insertion port 220 on the partition plate 200. The large end of the steel flow hole mold 700 is located outside the casting mold, that is, it passes through the mold through hole on the vertical plate 300 and extends to the outside of the vertical plate 300. One steel flow hole mold 700 is fixed on each side of the partition plate 200. During the casting process, the steel flow hole is directly formed in the middle of the V-shaped slag retaining wall through the steel flow hole mold 700.
