ABSTRACT:
A continuous casting tundish has a horizontal baffle intermediate its height. The baffle has a hole therethrough, to receive the downward flow of molten steel from the snorkel of a ladle, which flow educts steel through the hole and with it any desired additives such as alloying and/or refining agents. The space below the baffle is of lesser cross sectional area than the space above the baffle, and at least one end of the space below the baffle communicates with the space above the baffle, so that circulating flow of steel through the hole, below the baffle, and back over the baffle and again through the hole, is induced, that flow being turbulent below the baffle and laminar above the baffle. The tundish has the usual casting holes in its bottom.
