Slag scrapers in steel plants are mainly used for slag removal operations in the following aspects:
1. Converter Slag Removal
In converters, slag removal aims to eliminate non-metallic inclusions (such as oxides, silicon, manganese, etc.) from the molten steel surface. These inclusions can impair the quality and performance of steel, so slag removal must be performed before molten steel tapping.
2. Ladle Furnace Slag Removal
Slag removal in ladle furnaces is conducted during the molten steel refining process. Its purpose is to further purify the molten steel by removing inclusions generated during refining, ensuring the molten steel meets the required purity standards.
3. Ladle Slag Removal
Ladle slag removal is the final slag removal step before molten steel transportation and casting. At this stage, the goal is to eliminate secondary oxides and other inclusions that may form on the ladle inner wall during molten steel storage.
Slag removal is a critical process in steelmaking, directly affecting the composition, quality, and performance of steel. Therefore, great importance must be attached to slag removal operations, and relevant protective equipment (such as safety helmets, gloves, etc.) must be worn. Meanwhile, the frequency of slag removal varies depending on the furnace temperature and the type of slag raking equipment.
