Description

Technical Field

[0001] This utility model belongs to the technical field of slag retaining walls, specifically relating to a slag retaining wall for ironmaking. Background Technology

[0002] A slag retaining wall, also known as a weir, is a precast component made of refractory castable. It spans the entire width of the tundish, extending from the top of the tundish to a certain distance from the bottom. Molten steel can flow under it. The slag retaining wall is an important component of the continuous casting tundish. It can change the flow state of the molten steel in the tundish, prolong the residence time of the molten steel in the tundish, and promote the floating and discharge of slag inclusions in the molten steel. In use, molten steel flows from the ladle into the tundish, flows through the flow stabilizer to both ends of the tundish, and is blocked by the slag retaining wall. The slag retaining wall plays a very important role in molten steel treatment.

[0003] Patent No. CN202223362662.2 discloses a slag-blocking wall for continuous casting tundish, including a slag-blocking wall body. The slag-blocking wall body includes a planar wall, and arc-shaped walls are connected and installed on both sides of the planar wall. A first inclined wall and a second inclined wall are respectively connected and installed on the sides of the arc-shaped walls away from the planar wall. The first inclined wall and the second inclined wall are each provided with two mounting holes on the side away from the arc-shaped wall.

[0004] Although the aforementioned patent effectively improves the erosion resistance of the slag retaining wall of the continuous casting tundish by setting up reinforcing components, and can save costs to a certain extent, the replacement of the reinforcing components is hampered by the use of bolts for fixing. These bolts are subject to corrosion by molten steel during use, which makes it difficult to disassemble them. This increases the difficulty of operation for workers and results in low replacement efficiency. Therefore, there is an urgent need for a slag retaining wall for ironmaking to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a slag retaining wall for ironmaking. In view of the current situation of the prior art, a slag retaining wall for ironmaking that is easy to replace the reinforcing components, has a simple operation process, high replacement efficiency, and good performance is now provided.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a slag retaining wall for ironmaking, including a slag retaining wall body. A positioning groove is provided on one side wall of the slag retaining wall body. A carbon-containing reinforcing plate is installed in the positioning groove. Two sets of guide cavities are symmetrically arranged above the positioning groove. A fixing sleeve is installed above the guide cavity. A spring is provided in the fixing sleeve. One end of the spring is connected to a positioning rod. Two sets of positioning holes are symmetrically opened at the upper end of the carbon-containing reinforcing plate. A lever is fixed on one side wall of the positioning rod. A through cavity is opened at the position of the fixing sleeve corresponding to the lever.

[0007] Furthermore, the positioning groove is formed on the slag retaining wall body, and the carbon-containing reinforcing plate is inserted into the positioning groove.

[0008] By adopting the above technical solution, the positioning groove provides installation space for the carbon-containing reinforcing plate, which can greatly improve the erosion resistance of the slag retaining wall body and also improve the high-temperature flexural strength of the slag line area of ​​the slag retaining wall body, reduce the occurrence of cracking in the slag line area, and thus extend the service life of the slag retaining wall body.

[0009] Furthermore, the guide cavity is formed on the slag retaining wall body, the spring is welded inside the fixed sleeve, and one end of the positioning rod is welded to the bottom end of the spring.

[0010] By adopting the above technical solution, the guide cavity provides a through space for the positioning rod, and the positioning rod can move under the action of the spring.

[0011] Furthermore, the positioning rod is slidably connected to the fixed sleeve, the positioning rod passes through the guide cavity, the bottom end of the positioning rod has a beveled structure, the positioning rod is inserted into the positioning hole, and the positioning hole is formed on the carbon-containing reinforcing plate.

[0012] By adopting the above technical solution, when installing the carbon-containing reinforcing plate, the carbon-containing reinforcing plate is pushed to be placed in the positioning groove. During the pushing process, the carbon-containing reinforcing plate will apply an external force to the positioning rod, thereby causing it to move upward under the action of the spring. When the carbon-containing reinforcing plate is completely in the positioning groove, the positioning rod will be reset under the action of the spring rebound force and fixed in the positioning hole.

[0013] Furthermore, the through cavity is formed on the fixed sleeve, the lever passes through the through cavity, and the lever is welded to the positioning rod.

[0014] By adopting the above technical solution, the pusher block can easily apply external force to the positioning rod, causing it to separate from the positioning hole and release the fixation of the carbon-containing reinforcing plate.

[0015] Furthermore, two sets of lifting lugs are symmetrically fixed on both sides of the upper end of the slag retaining wall body.

[0016] By adopting the above technical solution, the lifting lugs facilitate the hoisting of the retaining wall body.

[0017] Furthermore, multiple sets of flow holes are arrayed near the bottom of the slag retaining wall body.

[0018] By adopting the above technical solution, the flow hole facilitates the flow of molten steel.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] To address the problem of low replacement efficiency in existing ironmaking slag retaining walls where bolts are used for reinforcing component replacement, and these bolts are susceptible to corrosion from molten steel, making disassembly difficult and increasing operator workload, this invention addresses this issue by incorporating a lever, spring, positioning rod, and positioning hole. During installation of the carbon-containing reinforcing plate, pushing it into the positioning groove causes it to exert external force on the positioning rod, which then moves upward under the spring's action. When the plate is fully within the groove, the rod returns to its original position within the positioning hole, securing it. The lever further facilitates the application of external force to the positioning rod, separating it from the hole and releasing the carbon-containing reinforcing plate. This allows for rapid replacement of the carbon-containing reinforcing plate, simplifying the operation and significantly improving the device's performance. Attached Figure Description
