Description

Technical Field

[0001] This utility model relates to the field of iron and steel smelting technology, and in particular to easily replaceable converter tapping hole liners. Background Technology

[0002] During the converter production process in steel plants, the inner diameter of the tapping spout increases with the number of uses, which can lead to the mixing of steel and slag during tapping. As the number of uses increases, the possibility of steel leakage at the tapping spout also increases. Therefore, it is necessary to replace the tapping spout regularly to alleviate the problem of the continuously increasing inner diameter of the tapping spout.

[0003] In the existing technology, in order to facilitate the installation of the tapping hole sleeve bricks on the converter, the tapping hole sleeve bricks are usually assembled into one piece by steel pipes and flanges. However, the flanges need to be fixed with multiple fixing bolts when assembling them. As a result, when replacing the tapping hole sleeve bricks, multiple fixing bolts need to be disassembled and installed in sequence, and tools are also required. This has the disadvantages of being cumbersome, time-consuming and labor-intensive, and needs to be improved.

[0004] Therefore, this utility model provides an easily replaceable converter tapping outlet liner to solve the above problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention provides an easily replaceable converter tapping hole sleeve brick, comprising: a converter body, a fixing mechanism, and a tapping hole sleeve brick;

[0006] The converter body is provided with a discharge pipe, a steel outlet sleeve brick is inserted into the discharge pipe, and a fixing mechanism is provided on the discharge pipe, which is connected to the steel outlet sleeve brick.

[0007] The fixing mechanism includes a limiting ball, a retaining ring, a spring, and a limiting component. Multiple limiting balls are slidably connected to the discharge pipe, and each limiting ball engages with the steel outlet sleeve. A retaining ring is slidably fitted onto the discharge pipe, and the retaining ring contacts and connects with the limiting balls. Left and right springs are fitted onto the discharge pipe, with one end of each spring fixedly connected to the retaining ring. Through the coordinated design of the discharge pipe, the steel outlet sleeve, and the fixing mechanism, the steel outlet sleeve can be quickly replaced without the need for tools, improving convenience and offering a simpler and more practical structure.

[0008] Preferably, the discharge pipe has a slot, the steel outlet sleeve brick slides in the slot, the slot is adapted to the steel outlet sleeve brick, and a limiting ring is fixedly connected inside the steel outlet sleeve brick. The limiting ring is in contact with the discharge pipe. The slot and the limiting ring facilitate the flow of molten steel into the steel outlet sleeve brick.

[0009] Preferably, a slot is provided on the outer side of the steel outlet sleeve brick, and the limiting ball engages with the slot. Through the interaction between the limiting ball and the slot, the steel outlet sleeve brick is fixed in a limited position.

[0010] Preferably, the discharge pipe is provided with multiple mounting grooves, and the multiple limiting balls slide in the multiple mounting grooves respectively. The multiple mounting grooves are adapted to the multiple limiting balls respectively, so as to facilitate the movement of the limiting balls.

[0011] Preferably, the discharge pipe is provided with a sliding groove, and a slider is slidably connected in the sliding groove. One end of the slider is fixedly connected to the limiting ball. The slider prevents the limiting ball from disengaging from the mounting groove.

[0012] Preferably, the limiting component includes a sleeve, a nut, and a second limiting ball. The sleeve is fixedly sleeved on the discharge pipe and fitted onto the retaining ring. The second limiting ball is slidably connected to the sleeve and engages with the retaining ring. A nut is threadedly connected to the sleeve and contacts the second limiting ball. A second slider is fixedly connected to the second limiting ball and slidably connected to the sleeve. After the steel outlet sleeve is fixedly installed, rotating the nut causes the nut to engage with the sleeve via threaded transmission, which in turn causes the nut to interact with the second limiting ball, engaging with the retaining ring and thus achieving the effect of limiting and fixing the retaining ring.

[0013] Compared with related technologies, the easily replaceable converter taphole sleeve bricks provided by this utility model have the following advantages:

[0014] This utility model provides an easily replaceable converter tapping hole sleeve brick. Through the coordinated design of the discharge pipe, the tapping hole sleeve brick and the fixing mechanism, the tapping hole sleeve brick can be quickly replaced without the aid of tools, which improves convenience and has a simpler and more practical structure.
