Description

Technical Field

[0001] This utility model relates to the field of refractory materials for steelmaking, and in particular to a device for fixing a porous polyester membrane core in a steel ladle porous seat brick. Background Technology

[0002] In the ladle refining process, the permeable seat brick is a core component for blowing inert gases (such as argon) into the molten steel. Currently, in the production of permeable seat bricks, the polyester film used to create the air channels is fixed with pins. This fixing process is cumbersome and lacks stability, easily causing the polyester film to loosen and fall off. This results in obstructed airflow in the finished permeable seat brick. If the airflow is obstructed, the steel mill must replace the permeable seat brick, impacting production schedules, increasing operating costs, and ultimately affecting the product quality and reputation of the ladle manufacturer. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing a steel ladle ventilated seat brick ventilated core polyester film fixing device.

[0004] To achieve the above objectives, the present invention can adopt the following technical solution:

[0005] The steel ladle ventilated seat brick ventilated core polyester film fixing device of this utility model includes a fixed end plate fixed to one end of the ventilated core of the steel ladle ventilated seat brick. The fixed end plate has a plurality of radially arranged strip-shaped insertion holes. The strip-shaped insertion holes are evenly distributed on the fixed end plate in the circumferential direction. A lifting plate is adapted to be inserted into the strip-shaped insertion holes. The upper part of the lifting plate has a lifting hole, and the lower part has a horizontal hanging hole for hanging the polyester film.

[0006] Furthermore, the fixed end plate has a circular structure with a center alignment hole at its center, which facilitates the fixed end plate to be fitted and aligned with one end of the ventilated core of the steel ladle ventilated seat brick in a frustum-shaped structure.

[0007] Furthermore, a pair of symmetrical fixing lugs are provided on the outer edge of the fixed end plate. The two fixing lugs are provided with internal thread fixing holes for inserting fixing bolts, so that the fixed end plate can be firmly attached to the end face of the air core of the steel ladle air seat brick by fixing bolts.

[0008] Furthermore, multiple horizontal hanging holes are evenly spaced along the height direction of the lifting plate, thereby allowing the hanging position of the polyester film to be adjusted according to usage needs.

[0009] Furthermore, based on the required number of air channels reserved in the air core of the steel ladle air seat brick, the strip-shaped insertion holes are 24 in number and are evenly distributed circumferentially on the fixed end plate.

[0010] The advantages of this utility model lie in its simple structure and ease of processing and use. By using a fixed end plate in conjunction with a lifting plate inserted into a strip-shaped socket, the polyester film can be easily and securely fixed during the processing of the ladle venting seat brick's venting core. This prevents the polyester film from loosening or falling off during processing, ensuring unobstructed airflow in the finished ladle venting seat brick's venting core, improving product quality, reducing production costs and operating costs for companies using the ladle venting seat brick's venting core, and enhancing product reputation.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 As shown, the steel ladle ventilated seat brick breathable core polyester film fixing device of this utility model includes a fixing end plate 1. The fixing end plate 1 has a circular structure, and its size is consistent with the large diameter end size of the frustum-shaped steel ladle ventilated seat brick breathable core to be processed, so that it can be perfectly fitted and fixed to the end face of the steel ladle ventilated seat brick breathable core. In order to facilitate the fitting and alignment of the fixing end plate 1 with the end face of the steel ladle ventilated seat brick breathable core, a center alignment hole 2 is also opened at the center of the fixing end plate 1; in order to make the fixing end plate 1 more secure, such as Figure 3 , 4As shown, a pair of fixing ear plates 3 are also provided on the outer edge of the fixing end plate 1. The two fixing ear plates 3 are symmetrically arranged on the left and right edges of the fixing end plate 1. At the same time, the two fixing ear plates 3 are flush with the fixing end plate 1 and integrally formed. The fixing ear plates 3 are provided with internal thread fixing holes 4 for inserting fixing bolts, so that the fixing end plate 1 can be firmly attached to the end face of the air core of the steel ladle air seat brick by fixing bolts.

[0019] The fixed end plate 1 has multiple concentrically arranged strip-shaped insertion holes 5. According to the number of air channels reserved in the air core of the steel ladle air seat brick to be processed, there are 24 strip-shaped insertion holes 5, which are evenly distributed on the fixed end plate 1 in the circumferential direction. The length of each strip-shaped insertion hole 5 is 33mm±0.1mm and the width is 3.5mm.

[0020] Each strip-shaped socket 5 is fitted with a lifting plate 6, which is tightly fitted into the strip-shaped socket 5 to ensure that the lifting plate 6 is securely inserted into the strip-shaped socket 5; for example Figure 5 , 6 As shown, the upper part of the lifting plate 6 is provided with a lifting hole 7, and the lower part is provided with a horizontal hanging hole 8. The length of the horizontal hanging hole 8 should be consistent with the width of the polyester film, so that the polyester film can pass through the horizontal hanging hole 8 and be hung on the lifting plate 6. In addition, multiple horizontal hanging holes 8 are evenly spaced along the height direction of the lifting plate 6, so that the hanging position of the polyester film can be adjusted according to the use needs.

[0021] In use, first insert the lifting plate 6 into the strip-shaped insertion hole 5, so that the horizontal hanging hole 8 at the bottom of the lifting plate 6 passes through the strip-shaped insertion hole 5 and is located below the fixed end plate 1 (e.g., Figure 2 As shown in the diagram, one end of the strip-shaped polyester film is then passed through the horizontal hanging hole 8 and hung on the lifting plate 6. The lifting plate 6 is then lifted upwards through the lifting hole 7 at the top, causing its lower edge to retract into the strip-shaped insertion hole 5, thus securely clamping the polyester film. The fixing end plate 1 can then be fixed to the end face of the ladle ventilated seat brick's ventilated core, thus completing the fixation of the polyester film. This prevents the polyester film from loosening or falling off during subsequent processing of the ladle ventilated seat brick's ventilated core, ensuring unobstructed airflow in the finished product after the polyester film is melted away. This improves product quality, reduces production costs and operating costs for companies using the ladle ventilated seat brick's ventilated core, and enhances product reputation.

[0022] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
