Description

Technical Field

[0001] The utility model belongs to the technical field of steel casting, and in particular relates to an online rapid cleaning device for fire cutting slag at the bottom of a casting blank. Background Art

[0002] When casting and producing continuous casting billets, metallurgical enterprises pay more and more attention to the surface quality of the continuous casting billets, especially the quality of the ends of the continuous casting billets. However, the bottom of the continuous casting billets cut by fire cutting machines have "slag" and "cold nodules" problems to varying degrees. These defects will cause surface scratches and cracks on the rolled materials when the continuous casting billets are rolled into rolled products. Therefore, the "slag" and "cold nodules" at the bottom of the continuous casting billets must be cleaned before rolling.

[0003] At present, there are generally two ways to clean the slag from the bottom of the continuous casting billet, manual cleaning or mechanical cleaning with hydraulic cylinders. Manual cleaning is time-consuming and labor-intensive, with low labor productivity and prone to omissions; while mechanical cleaning with hydraulic cylinders requires a hydraulic pump station and multiple hydraulic cylinder devices, with high investment costs, and high-temperature cutting can easily cause problems such as hydraulic system leakage, resulting in insufficient stable operation of the equipment.

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] like Figure 1 and Figure 2 As shown, a technical solution is provided below:

[0019] An online rapid cleaning device for the flame cutting slag at the bottom of the ingot comprises a moving trolley 1, a rotating chain 2 is arranged on the moving trolley 1, the rotating chain 2 is made of steel, the bottom of the ingot is opposite to the rotating chain 2, the rotating chain 2 whips the bottom of the ingot by rotating, a sliding track 3 is arranged below the moving trolley 1, the sliding track 3 is made of channel steel, and the moving trolley 1 is slidingly connected to the sliding track 3. The rotating chain 2 rotates and continuously hits the "hanging slag" and "cold nodules" at the bottom of the ingot, so that the "hanging slag" and "cold nodules" are separated from the bottom surface of the ingot, and cleaning can be achieved; moving the moving trolley 1 along the sliding track 3 can achieve multi-stream cleaning.

[0020] A cleaning motor 21 is installed on the mobile trolley 1, and the cleaning motor 21 can be rotated forward and reversely, and the output end of the cleaning motor 21 is connected to the rotating chain 2 through a connecting rod 22. The cleaning can be more thorough by the forward and reverse bidirectional rotation of the cleaning motor 21.

[0021] A U-shaped lock buckle 4 is provided at one end of the rotating chain 2, and a through hole is provided on the connecting rod 22. Lock holes are provided at both ends of the U-shaped lock buckle 4, and bolts 41 are passed through the lock holes. The bolts 41 pass through the lock holes on one side in turn, and are connected to nuts after passing through the through holes and the lock holes on the other side, thereby realizing a detachable connection between the rotating chain 2 and the connecting rod 22, which is convenient for replacing the rotating chain 2.

[0022] The device also includes two fixed pulleys 5 and a driving motor 6. The two fixed pulleys 5 are rotatably connected with steel wire ropes 7. The moving trolley 1 is connected to the steel wire ropes 7. The driving motor 6 is connected to one of the fixed pulleys 5, thereby driving the moving trolley 1 to slide along the sliding track 3.

[0023] After the continuous casting billet is cut, it moves along the conveyor roller to the cleaning position and stops. Then the operator turns on the drive motor 6 to drive the mobile trolley 1 to move, moves the mobile trolley 1 to the position of the flow to be cleaned and stops, and then turns on the cleaning motor 21. The cleaning motor 21 rotates forward for a certain time, and then reverses for a certain time (the specific time is adjusted according to the on-site cleaning state). The steel rotating chain 2 uses the high-speed rotation kinetic energy to whip the bottom surface of the billet to complete the cleaning work. After cleaning the continuous casting billet of one flow, repeat the above operation to clean the bottom surface of the continuous casting billet of other flows.

[0024] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
