[0002] During the smelting process of the converter, its internal reaction is violent, and part of the converter contents will splash out of the converter, and part of the slag will fall onto the ladle car track under the converter, which results in the track under the converter being covered with slag, which seriously affects the movement of the ladle car under the furnace; currently, the slag on the track under the furnace is cleaned by a forklift or a long hand-held shovel, which is not only inefficient but also has certain safety hazards; some steel mills also set slag scrapers at the end of the ladle car to scrape off the slag on the track along the way. As the scraper plate moves forward, it will inevitably be worn, which will cause the scraper plate to be unable to effectively contact the track in the later stage, and the slag cannot be effectively cleaned; therefore, a track cleaning device is needed, which is required to cooperate with the ladle car to effectively clean the slag on the track on the way forward.
