What is clean steel continuous casting
The production of high-quality continuous casting slabs requires that the content of inclusions in molten steel be controlled within the specified range. In the process of steelmaking-refining-continuous casting, steelmaking and refining are the basis for ensuring the cleanliness of molten steel. Compared with die casting, due to the special conditions of continuous casting, it is more difficult to obtain clean slabs with extremely low inclusion content from clean molten steel after steelmaking and refining. How to ensure the cleanliness of molten steel and obtain clean billets is the clean steel continuous casting technology. The technological measures related to clean steel continuous casting are: (1) Pouring without oxidation protection: The casting time of continuous casting is long, and the area of molten steel exposed to the air is large, which greatly increases the possibility of secondary oxidation of molten steel. The non-oxidative protection pouring technology...
