Description

Technical Field

[0001] The utility model relates to the technical field of slab continuous casting dephosphorization equipment, in particular to a dephosphorization device for iron oxide scale on the surface of a continuous casting slab. Background Art

[0002] During the slab continuous casting process, the molten steel in the large ladle flows into the tundish through the casing, and the molten steel in the tundish flows into the crystallizer through the invasive nozzle, forming a primary slab shell in the crystallizer. In the secondary cooling section, water is used to cool the incompletely solidified continuous casting slab, and finally a completely solidified continuous casting slab is formed. During the solidification of the continuous casting slab in the secondary cooling section, a layer of iron oxide scale will be formed on the surface of the continuous casting slab, especially the iron oxide scale on the narrow side of the continuous casting slab. If it cannot be effectively removed, it will affect the normal coding of the subsequent process spraying machine, thereby affecting the recognition of the continuous casting slab in the next process. Summary of the invention

[0003] The utility model provides a flexible dephosphorization device for continuous casting slabs, which can effectively remove the oxidized iron scale on the narrow side surface of the continuous casting slabs, thereby solving the problem that the above-mentioned spraying machine has unclear spraying numbers due to the oxidized iron scale on the narrow side surface of the continuous casting slabs, which affects the recognition of the continuous casting slabs in the next process.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is:

[0005] It includes a roller conveyor for conveying the continuous casting slab, wherein fixed seats are respectively installed on both sides of the roller conveyor, a vertically arranged bearing is arranged above the fixed seat, a rotating shaft is arranged outside the bearing sleeve, a horizontally arranged fixed pipe is arranged on the side of the rotating shaft close to the roller conveyor, and a steel wire rope is arranged at the end of the fixed pipe; a connecting rod is arranged on the other side of the rotating shaft, and a tension spring is connected to the end of the connecting rod, and the tension spring is fixedly installed on both sides of the roller conveyor through a spring bracket.

[0006] In the above technical solution, a more specific technical solution may also be: the steel wire rope is a flexible steel wire rope.

[0007] Furthermore, one end of the steel wire rope is inserted into and fixed in the fixing tube.

[0008] Furthermore, there are more than two fixed pipes, which are installed on the rotating shaft in an upper and lower structure.

[0009] Furthermore, the connecting rod is in an inverted L shape, and the upper end of the connecting rod is connected to the rotating shaft, and the lower end of the connecting rod is connected to the spring bracket.

[0010] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0011] 1. The utility model has a simple structure and can realize flexible contact between the steel wire rope and the surface of the continuous casting slab, effectively removing the iron oxide scale on the surface, thereby solving the problem that the spraying machine has unclear spraying numbers due to the iron oxide scale on the narrow side surface of the continuous casting slab, which affects the recognition of the continuous casting slab in the next process.

[0012] 2. The utility model inserts and fixes one end of the steel wire rope in the fixing tube. When the steel wire rope is worn or damaged and needs to be replaced, the steel wire rope can be quickly pulled out and replaced with a new one.

[0013] 3. In the utility model, since the rotating shaft is provided with a connecting rod, the end of the connecting rod is connected with a tension spring, and the tension spring is fixedly installed on both sides of the roller table through a spring bracket and on the same side as the fixing seat. With such an arrangement, automatic recovery can be achieved through the tension spring and the rotating shaft after the continuous casting slab passes through. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings:

[0019] like Figure 1-3 A flexible dephosphorization device for continuous casting slabs is shown, which includes a roller 10 for conveying continuous casting slabs 1, fixed seats 2 are respectively installed on both sides of the roller 10, and a vertically arranged bearing 3 is arranged above the fixed seat 2. The outer sleeve of the bearing 3 is provided with a rotating shaft 4, and a horizontally arranged fixed pipe 5 is arranged on the side of the rotating shaft 4 close to the roller 10, and a steel wire rope 6 is arranged at the end of the fixed pipe 5. The steel wire rope 6 has a certain flexibility and can achieve flexible contact with the surface of the continuous casting slab 1, thereby effectively removing the iron oxide scale on the surface. A connecting rod 7 is arranged on the other side of the rotating shaft 4, and a tension spring 8 is connected to the end of the connecting rod 7. The tension spring 8 is fixedly installed on both sides of the roller 10 through a spring bracket 9 and on the same side as the fixed seat 2. The presence of the tension spring 7 and the connecting rod 7 enables the utility model to achieve automatic recovery after the continuous casting slab 1 passes.

[0020] The steel wire rope 6 is a flexible steel wire rope.

[0021] One end of the steel wire rope 6 is inserted into and fixed in the fixing tube 5. With such arrangement, when the steel wire rope 6 is worn or damaged and needs to be replaced, the steel wire rope 6 can be quickly pulled out and replaced with a new one.

[0022] There are more than two fixed pipes 5 , which are installed on the rotating shaft 4 in an upper and lower structure. The specific number can be set according to the height of both sides of the continuous casting slab 1 .

[0023] like Figure 4 As shown, the connecting rod 7 can also be configured to be an inverted L-shape, with the upper end of the connecting rod 7 connected to the rotating shaft 4 , and the lower end of the connecting rod 7 connected to the spring bracket 9 .

[0024] The specific operation method of using the utility model to remove the iron oxide scale on the narrow side surface of the continuous casting slab is as follows:

[0025] The utility model is installed on both sides of the narrow surface of the continuous casting slab 1. When the continuous casting slab 1 is conveyed along the roller table 10, the steel wire rope 6 of the utility model will closely contact the narrow surface of the continuous casting slab 1, thereby effectively removing the oxidized iron scale attached thereto. After the continuous casting slab 1 passes, the utility model can realize automatic recovery through the tension spring 7 and the rotating shaft 4. At the same time, since the steel wire rope 6 is installed in the fixed tube 5, it can be quickly replaced when necessary.
