Description

Technical Field

[0001] The utility model relates to a tundish quick-change slide storage tool rack, belonging to the technical field of steelmaking equipment in the metallurgical industry. Background Technique

[0002] The tundish quick-change slide is a key part used in the tundish to control the flow rate of molten steel during the pouring of the tundish, and it is an important link in the continuous casting protective pouring. The flow rate of molten steel entering the mold depends entirely on the size of the aperture of the quick-change slide. Therefore, the tundish quick-change slide has various aperture specifications. At the same time, the tundish quick-change slide plays a role in connecting the upper nozzle of the tundish and the submerged nozzle, protecting the molten steel from secondary oxidation and can adjust the drawing speed to stabilize the production rhythm.

[0003] The main materials of the tundish quick-change slide are composed of ZrO2 and Al2O3. During the production process, it is continuously scoured and eroded by high-temperature molten steel, and its service life is generally 6-8 hours. Therefore, it needs to be replaced regularly. Otherwise, the molten steel will penetrate through the quick-change slide, causing abnormal overflow of high-temperature molten steel, resulting in production interruption and equipment burnout in the lightest case, and even causing casualties in the most serious case.

[0004] At present, after the tundish quick-change slide is manufactured, it is stored in a packing box, and the packing box is directly sent to the continuous casting machine platform for use. After the box is opened, the storage of the slides is chaotic. Before replacing the quick-change slide, the operator needs to take out the slide from the packing box and confirm the aperture of the quick-change slide used before proceeding with the subsequent replacement operation of the quick-change slide. This operation method is prone to incorrect use of the aperture of the quick-change slide, and the quick-change slide is prone to being knocked during placement, resulting in wear of the quick-change slide, affecting its service life and causing unnecessary losses. Content of the Utility Model

[0005] The purpose of the utility model is to provide a tundish quick-change slide storage tool rack, which is convenient for taking and placing the tundish quick-change slide, avoids knocking of the tundish quick-change slide, eliminates the phenomenon of chaotic storage of the tundish quick-change slide, and solves the problems existing in the background technique.

[0008] The upper inclined chute and the lower inclined chute are connected into a whole through the intermediate transition chute, presenting a V-shaped structure.

[0009] The included angle α between the lower inclined chute and the bottom plate is 40°-50°, and the included angle β between the upper inclined chute and the lower inclined chute is 60°-80°.

[0010] Both the upper inclined chute and the lower inclined chute are of an upper-open structure, and the intermediate transition chute is of an arc-shaped closed structure.

[0023] The following further illustrates the present utility model by way of examples in conjunction with the drawings.

[0024] Refer to the attached Figure 1-6, A tundish quick-change slider storage tool rack, comprising a bottom plate 1, a support plate 2, an upper inclined chute 7, an intermediate transition chute 8, and a lower inclined chute 9. The support plate 2 is vertically fixed on the bottom plate 1. The lower end of the lower inclined chute 9 is fixed on the bottom plate 1, and the upper end of the lower inclined chute 9 is fixed on the support plate 2. The upper inclined chute 7 and the lower inclined chute 9 are connected into a whole through the intermediate transition chute 8. The upper inclined chute 7, the intermediate transition chute 8, and the lower inclined chute 9 each comprise a plurality of chutes, and each chute corresponds to a tundish quick-change slider 10 of a specific specification.

[0025] In this embodiment, referring to the appendix Figure 1-6 , The bottom plate 1 is a rectangular steel plate, and the support plate 2 is vertically welded on the bottom plate 1 to improve the stability of the tool rack.
