Setting a slag retaining weir in the tundish can stabilize the molten steel, promote the upward flow of the molten steel and the floating of inclusions, which is beneficial to the separation of steel and slag, prevent the molten slag from entering the mold, and improve the quality of the molten steel. The impact plate is used in the molten steel impact zone of the tundish.
