Description

Technical Field

[0001] The utility model relates to a slag cleaning device for a converter ladle car track, belonging to the technical field of metallurgical steelmaking equipment. Background Art

[0002] Converter steelmaking uses molten iron, scrap steel, and ferroalloys as the main raw materials, without the help of external energy, and relies on the physical heat of the molten iron itself and the heat generated by the chemical reaction of the molten iron components to complete the steelmaking process in the converter. Since a large amount of oxygen needs to be blown into the blowing process, the carbon-oxygen reaction is violent, which is easy to cause splashing. Although various steel companies have taken various measures to suppress it, they still cannot 100% eliminate converter splashing. Converter splashing will splash high-temperature liquid slag and even part of the molten steel onto the track. In severe cases, it needs to be cleaned up manually on the spot. Slag is prone to accumulation on the track under the converter, causing the ladle car to derail. The derailment of the ladle car takes a long time to handle, which affects the normal smelting rhythm of the converter, often causing production accidents and bringing great economic losses. However, it is unrealistic to arrange on-site operating staff to check and clean the slag on the ladle car track in real time in actual steelmaking production. Therefore, how to effectively clean the slag on the track has become one of the industry's problems. Some companies use slag pushers for ladle cars, but they cannot clean the slag and cannot prevent the derailment of ladle cars. Utility Model Content

It can clean the slag on the ladle car track, reduce the labor intensity of employees and reduce the risk of working under the furnace, effectively prevent the ladle car from derailing, and reduce production accidents.

[0004] The technical solution adopted by the utility model to solve the above-mentioned problem is: a slag cleaning device for a converter ladle car track, comprising four groups of slag cleaning units, the slag cleaning units respectively corresponding to four wheels, the four groups of slag cleaning units are symmetrically arranged at both ends of the ladle car frame and arranged on the outer sides of the corresponding wheels; any of the slag cleaning units respectively comprises a slag cleaning plate, a connecting frame is arranged on the side of the slag cleaning plate, two symmetrically arranged plow shovels are arranged on the connecting frame, and the plow shovels are respectively arranged on both sides of the track.

[0005] The slag cleaning plate is rectangular, and the distance between the bottom end of the slag cleaning plate and the track is 1 to 3 mm.

DETAILED DESCRIPTION

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0016] like Figure 1 As shown, a slag cleaning device for a converter ladle car track in this embodiment includes four groups of slag cleaning units 3, each of which corresponds to four wheels 2. The four slag cleaning units 3 are symmetrically arranged at both ends of the ladle car frame 1 and arranged on the outside of the corresponding wheels 2. Whether the ladle car moves forward or backward, the track slag can be cleaned. Figure 2 As shown, each slag cleaning unit 3 includes a rectangular slag cleaning plate 3.1, the side of the slag cleaning plate 3.1 is fixedly connected to one end of an arc-shaped connecting rod 3.2, the other end of the arc-shaped connecting rod 3.2 is fixedly connected to a U-shaped bracket 3.3, and plowshares 3.4 are respectively arranged on the two legs of the U-shaped bracket 3.3, and the plowshares 3.4 are respectively arranged on both sides of the track. The horizontal spacing between the two plowshares 3.4 in the same slag cleaning unit exceeds the track width by 2mm to prevent the plowshares from slightly deforming and touching the track to affect the operation of the ladle car.

[0017] During the operation of the ladle car, the slag cleaning plate is used to clean the slag splashed on the track during steelmaking. The thickness is 2-3cm. Sufficient thickness can prevent it from being deformed by force. The width of the slag cleaning plate is about 20cm, and the bottom of the slag cleaning plate is kept about 2cm away from the track. If the distance is too small, the bottom of the slag cleaning plate is likely to touch the track when the track is slightly deformed, causing the ladle car to have difficulty in running; if the distance is too large, it cannot effectively play the role of cleaning the slag on the track.

[0018] like Figure 3 As shown, the plowshare 3.4 includes a plowshare wall 3.4.1 and a plow tip 3.4.3, the plowshare wall 3.4.1 is fixed to the ladle car frame 1, and the plowshare wall 3.4.1 and the plow tip 3.4.3 are connected by an arc plate 3.4.2. The two plowshares in the same slag cleaning unit are symmetrically distributed with the track as the axis, ensuring that the plowshares clean the slag to both sides of the track.

[0019] The tip of the plow is slightly lower than the horizontal plane of the top of the track in the vertical direction. The specific data is set according to the actual situation on site, so that the slag that has not been cleaned by the slag cleaning plate can be cleaned.

[0020] The widest part of the shovel wall is about 4 cm. The plow shovel is mainly used to clean the slag within 3 cm of the track. The slag cleaning plate serves as the first line of defense for cleaning slag on the ladle car track and cleans up large pieces of slag. The plow shovel serves as the second line of defense for cleaning thinner slag close to the track, thereby cleaning the slag on the ladle car track and effectively preventing the ladle car from derailing.

[0021] When encountering serious spattering during converter steelmaking, slag is accumulated on both sides of the track and the track is not seriously deformed. If the amount of slag is not large, the ladle car can be started to push the slag under the command of professionals. The slag cleaning plate cleans the slag with high resistance and high accumulation height, and the plow shovel is the second line of defense to clean the slag with relatively small resistance and the accumulated slag on the track to ensure smooth production and wait for the production rhythm to allow for detailed cleaning. When large pieces of slag are accumulated on both sides of the track and hinder the operation of the ladle car, the slag cleaning device cannot play an effective role after analyzing the on-site situation. Do not act recklessly at this time, otherwise it is easy to damage the slag cleaning plate or even the plow shovel.

[0022] The application has a simple structure, is durable, and is safe to use. It can clean the slag on the ladle car track, replacing the manual slag cleaning, reducing the labor intensity of employees and the risk of working under the furnace, effectively preventing the ladle car from derailing, reducing production accidents, ensuring a stable steelmaking production rhythm, and having high economic benefits.

[0023] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
