Description

Technical Field

[0001] The utility model relates to a slag scooping system, in particular to a leaping mobile ladle slag scooping system, belonging to the technical field of slag scooping equipment. Background Art

[0002] A large amount of slag will be generated during the metal smelting process, floating on the surface of the ladle or the smelting furnace. If the slag is not cleaned up, it will affect the quality of the molten iron and castings. There are two main ways to remove slag in the smelting industry: manual slag removal and mechanical slag removal. The emergence of mechanical slag removal breaks the traditional manual slag removal. Mechanical slag removal only requires remote control, and the slag in the furnace can be removed through the slag removal gripper. Mechanical slag removal can use various protective devices to make the working process safer and more reliable, ensuring the long-term stable operation of the smelting equipment.

[0003] However, the existing ladle slag remover still has the following technical problems in actual use:

[0004] Ladle slag scooping machines have poor flexibility and cannot be moved over long distances. They generally require a large amount of installation work and require a concrete foundation to be specially poured or a steel structure frame to be erected to raise the installation plane of the equipment in order to achieve the purpose of scooping the slag in the ladle. When in use, the slag scooping gripper can generally only scoop a single ladle in a fixed direction and point, and cannot take into account the ladles on double or multiple rows of tracks, and cannot automatically locate the ladle openings of different ladles. It has great limitations and is not convenient for scooping slag from different ladles. The slag scooping gripper cannot omnidirectionally grab the slag in the furnace, and is prone to grabbing dead corners, resulting in a lot of room for improvement in the slag scooping effect.

[0005] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
