Zusammenfassung:	PURPOSE:To reduce the unevenness of temp. in each strand in a tundish. CONSTITUTION:In the tundish 1 for continuous casting having plural strands, inert gas blowing nozzles 2 facing in mutual reverse direction at both side surfaces in the tundish 1 are arranged a little upward. By blowing the inert gas from the inert gas blowing nozzles 2, the stirring flows 5, 6 in the right- handed rotation and the left-handed rotation are caused while interposing a molten steel pouring hole 3. By this method, the evenness of the molten steel overheating degree DELTATmold in a mold in each strand in the tundish can drastically be reduced and the quality of the cast slab can be stabilized.
