| 摘 要： | The influence of flow control devices on metallurgical effects in large-capacity tundish has been studied carefully with elements tracing,sampling and theoretical prospecting,The results from the studies are(1) in the continuous casting of clean steel,bad control of tundish operation may deteriorate the cleanliness of steel;(2) the cleanliness of steel is deteriorated mainly at the unstady state;(3) large amount of macro inclusions come from the top slag and the refractory of tundish;(4) installing dam and weir can improve the cleanliness of steel and lighten the influence of steel fluctuation;and (5) the result of theoretical calculation suggests that the inclusions larger than the critical size of 92.6um can be floated out from the tundish bath completely.

| Abstract: | The influence of flow control devices on metallurgical effects in a large-capacity tundish has been studied carefully with elements tracing, sampling and theoretical prospecting. The results from the studies are (1) in the continuous casting of clean steel, bad control of tundish operation may deteriorate the cleanliness of steel; (2) the cleanliness of steel is deteriorated mainly at the unsteady state; (3) large amount of macro inclusions come from the top slag and the refractory of tundish; (4) installing dam and weir can improve the cleanliness of steel and lighten the influence of steel fluctuation; and (5) the result of theoretical calculation suggests that the inclusions larger than the critical size of 92.6 μm can be floated out from the tundish bath completely. |
