Description

Technical Field

[0001] This utility model relates to the field of impact barrel technology, specifically an impact barrel for intermediate tundishes. Background Technology

[0002] The tundish is an important processing step in short-process steelmaking. It usually needs to be used in conjunction with an impact barrel to guide the high-temperature molten steel into the tundish, and then the tundish nozzle distributes it to each crystallizer to complete the important steelmaking process. The impact barrel is used to store the high-temperature molten steel and can flexibly transfer the molten steel for processing.

[0003] In existing technologies, when molten steel is being guided by an impact ladle, it is usually discharged from a single outlet, which results in a slow discharge efficiency that cannot be adjusted according to demand. Utility Model Content

[0005] To solve the above technical problems, the present invention provides the following technical solution: an impact barrel for intermediate packaging, comprising an impact barrel, wherein a splicing component is provided on the inner side of the impact barrel, and the splicing component is used to separate two sets of structures for easy maintenance; an adjustment component is provided at the bottom of the splicing component, and the adjustment component is used to control the flow rate according to requirements.

[0006] The splicing assembly includes an inner barrel, and a limiting ring is installed on the top of the inner barrel. Two sets of inner hanging rings are installed on the top of the limiting ring, and a guide cone is installed on the bottom of the inner side of the inner barrel.

[0007] The adjustment component includes a rotating disk, and an annular groove is provided on the top of the rotating disk. Four sets of guide pipes are installed at the bottom of the annular groove. Two sets of guide pipes are arranged correspondingly, and the other two sets of guide pipes are arranged on the same side. Two sets of corresponding guide grooves are provided at the bottom of the inner barrel.

[0008] Preferably, a support ring is installed at the bottom of the inner side of the impact barrel, and the support ring is located at the bottom of the inner barrel.

[0009] Preferably, the top of the impact barrel is equipped with six sets of positioning posts, and the top of the front and back of the impact barrel are respectively equipped with two sets of external hanging rings.

[0010] Preferably, the top of the limiting ring is provided with six sets of positioning holes, and the positioning holes are installed on the outer side of the positioning post.

[0011] Preferably, a limiting frame is installed at the bottom of the inner tub, and the limiting frame is located outside the rotating disk. A welding ring is installed at the bottom of the inner tub, and the welding ring is located inside the annular groove.

[0012] Preferably, a connecting bearing is installed at the top of the rotating disk, and the connecting bearing is located inside the guide cone, and an adjusting column is installed at the bottom of the rotating disk.

[0013] Preferably, a number of support wheels are embedded at the bottom of the outer ring of the rotating disk, and the support wheels are located at the bottom of the inner side of the limiting frame.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0015] First, this utility model has an adjustment component installed. The inner rotating disk can be restricted by the limiting frame. The rotating disk needs to be controlled by an external device to rotate the adjustment column, thereby driving the rotating disk to rotate and adjust along the connecting bearing. During the adjustment process, the guide pipe will overlap with the guide groove. The overlap can have single or double discharge effects. The rotation method can be used to adjust according to different needs.

[0016] Secondly, this utility model features a splicing component. Existing impact barrels are typically integral in structure, and the installation and disassembly of the suspended structure require a long time. In addition, maintenance will affect normal processing. By setting an inner barrel, it can be separated from the outer barrel. The inner barrel can be lifted out directly using the suspension structure and replaced with a usable inner barrel for assembly, allowing for normal processing. Damaged inner barrels can be easily disassembled for maintenance. At the same time, the guide cone set in the inner barrel can disperse the high-temperature molten steel poured into it, which can prevent splashing. Attached Figure Description
