| Abstract Scope |
The tundish structure is a very important factor to remove the inclusions and unify the molten steel. In the condition of four-strand asymmetrical tundish form, there are many problems in Al-deoxidized steel, such as a large number of inclusions and excessive inclusion size. In order to remove the inclusions and increase the cleanliness of molten steel, the crutch-shaped baffle was designed for the four-strand asymmetrical tundish. The numerical simulation results showed that by applying the proposed baffle, the average residence time of the molten steel in the tundish is increased by 43.1s, the deadzone ratio is decreased by 3.4%, and the flow consistency among strands is apparently increased. Industrial experiments showed that the excessive-sized inclusions are eliminated and the inclusion number is decreased by 46.23% when adding the crutch-shaped baffle in four-strand asymmetrical tundish. Therefore, the inclusion removal rate and the cleanliness of molten steel are greatly improved. |
