[0002] Slag is a solid waste generated by pyrometallurgy, combustion process or other high-temperature industrial production process. It is mainly composed of molten or partially molten inorganic substances, including incompletely burned minerals, flux, metal oxides and other non-metallic impurities. In metallurgy, slag is usually formed by reaction with gangue components in ore and added slag-forming materials during the smelting process. Slag cleaning device is a mechanical equipment specially designed to remove accumulated slag from the inner wall of the furnace body to ensure the cleanliness of the furnace body and maintain its normal operating efficiency. This type of device uses a mechanical transmission system to enable the scraper to reciprocate or rotate along the furnace wall to scrape off the slag. The scraper in the existing slag cleaning device is fixed in size, which means that it can only match and adapt to the inner wall of the furnace body within a specific diameter range, and has low adaptability.
