Abstract：With three-strand H-beam blank continuous castingtundish as the research object, the computational fluid dynamic software FLUENTwas adopted to build three dimensional geometry model and simulate the transfercharacteristic in the tundish for H-beam blank continuous casting under highercasting speed. The resultsshowed that the tundish had the optimized comprehensive performance when the diameterof flow-guiding bore(D) is 100 mm, the height of flow-guiding bore(H)is 550 mm and the angle between two flow-guiding bores(θ) is 50°.
