Description

Technical Field

[0001] The utility model relates to the technical field of continuous casting, in particular to a multifunctional tundish cleaning device. Background Art

[0002] The tundish is an important refractory container in continuous casting production. The molten steel injected from the ladle is distributed to each crystallizer through the tundish. Usually, the tundish plays the role of continuous pouring, diversion, decompression and stabilization, prevention of secondary oxidation, and removal of impurities. During the continuous casting process, the molten steel is in direct contact with the working layer of the tundish. The impurities such as the coating and iron oxide scale remaining in the tundish are highly likely to enter the crystallizer with the steel flow, eventually forming slag inclusions and inclusion defects. In order to ensure the cleanliness of the online tundish, it is necessary to clean the tundish to avoid affecting the quality of the continuous casting billet.

[0003] At present, the cleaning of the tundish is mainly done by sweeping with a broom or by sucking out the floating dust and residues in the tundish through an air duct. However, it is difficult to clean the paint and iron oxide sheets adhering to the tundish wall, slag retaining wall and tundish bottom, which causes pollution to the molten steel. When necessary, manual entry into the tundish is required for cleaning, which increases the labor intensity and safety risks of the workers. During the pouring process, the molten steel may be washed away and peeled off and enter the molten steel, causing the risk of inclusions. Utility Model Content

[0024] like Figure 1 to Figure 2 As shown, according to an embodiment of the utility model, a multifunctional tundish cleaning device is provided, such as Figure 1 As shown, the device comprises a first pipeline 1 and a second pipeline 2, wherein one end of the second pipeline 2 is connected to the side wall of the first pipeline 1, one end of the first pipeline 1 is connected to a high-pressure gas source 3, and a blocking cone 4 is provided near the other end of the first pipeline 1, and the blocking cone 4 can block the other end of the first pipeline 1. The device blocks or opens the other end of the first pipeline 1 by setting the blocking cone 4, changes the flow direction of the high-pressure gas generated by the high-pressure gas source 3, and thus realizes the free switching of the purging and suction functions.

[0025] Furthermore, the first pipeline 1 is closed by the blocking cone 4, and the high-pressure gas generated by the high-pressure gas source 3 flows through the first pipeline 1 and the second pipeline 2 in sequence and is blown out from the other end of the second pipeline 2 to realize the purging function; when the other end of the first pipeline 1 is open, the high-pressure gas generated by the high-pressure gas source 3 is blown out from the other end of the first pipeline 1, and the high-pressure gas generates a negative pressure in the second pipeline 2, and the residues in the tundish are sucked in through the other end of the second pipeline 2, and the residues sucked into the second pipeline 2 are discharged from the other end of the first pipeline 1 along with the high-pressure gas to realize the suction function. When the blocking cone 4 is used to block the first pipeline 1, the device can be used as a blowpipe for purging. When the blocking cone 4 is removed, the high-pressure gas flows out from the other end of the first pipeline 1, and a negative pressure is formed in the second pipeline 2, which can suck the floating dust, residues, etc. inside the tundish into the second pipeline 2. The device is used to purge and suck the tundish, and the inside of the tundish is effectively cleaned.

[0026] Furthermore, one end of the second pipeline 2 is communicated with the middle portion of the first pipeline 1 , and the second pipeline 2 and the first pipeline 1 are connected by welding.

Such an arrangement enables the residue of the tundish to be discharged smoothly through the second pipeline 2 and the first pipeline 1.

[0028] Furthermore, a scraper 5 is provided at the other end of the second pipe 2, and the scraper 5 can be used to scrape and clean the residues on the tundish wall, the tundish bottom and the slag retaining wall. In view of the problem that the paint, oxidized iron scale and other debris stubbornly adhering to the tundish wall, the slag retaining wall and the tundish bottom are difficult to clean, the scraper 5 is installed at the other end of the second pipe 2 to achieve scraping and cleaning of the tundish wall, the slag retaining wall and the tundish bottom.

[0029] Furthermore, if Figure 2As shown, the scraper 5 includes a body 6 and a shovel handle 7, the body 6 and the shovel handle 7 are an integrated structure, the shovel handle 7 includes a first section 8 and a second section 9, the first section 8 is a tubular structure, the second section 9 is a hollow frustum structure, one end of the first section 8 is connected to the other end of the second pipe 2, the small end of the second section 9 is connected to the other end of the first section 8, and one end of the body 6 is connected to the large end of the second section 9.

[0030] Furthermore, the body 6 is a hollow prism structure, and the side wall at the other end of the body 6 is a plane. The side wall at the other end of the body 6 is used to scrape and clean the residues adhering to the wall, bottom and slag retaining wall of the tundish. The body 6 is made of flat metal sheets, and the interior of the body 6 is a hollow pipe. The metal sheet is used to scrape and peel off foreign matter such as paint, iron oxide and the like adhering to the wall and bottom of the tundish, and then the device is used for suction, and the debris is discharged through the first pipe 1, so as to achieve a deep cleaning effect.

[0031] Furthermore, the body 6 is tilted relative to the shovel handle 7, and the angle between the axis of the body 6 and the axis of the shovel handle 7 is 30° to 60°. Such a configuration can facilitate the scraper 5 to scrape and clean the tundish.

[0032] Furthermore, the blocking cone 4 is connected to the first pipeline 1 through a connecting rope 10 .

[0033] Furthermore, the pressure of the high-pressure gas generated by the high-pressure gas source 3 is 0.2 MPa to 0.6 MPa.
