The use conditions of the impact zone of thin slab CSP tunware are harsh,which has been scoured by molten steel for a long time,and the slag system in the impact zone is relatively complex.In order to solve the problems such as scoured and eroded by molten steel in the impact zone,the material,appearance size and installation mode of the impact plate in the impact zone are optimized and adjusted.In order to improve the corrosion resistance of the slag line,ultrafine powder and raw material grade are introduced.At the same time,the weak link in the impact zone of tundish is solved by laying the protection plate on the slag line in the impact zone,which provides a reliable guarantee for increasing the number of pouring furnaces in the middle ladle,and also eliminates the safety risk of steel leakage in the impact zone of tundish.
