PURPOSE: To release the peeling and the damage of coating at the part brought into contact with molten metal flowed down from a triangle ladle by constituting with a standing-up part and a slow inclining part in the chute so as to bring the molten metal flowed down from the ladle into contact with the slow inclining part.

CONSTITUTION: As the chute 12 is provided with the standing-up part 14 and the slow inclining part 16, and formed so as to have sufficient height, even if the pouring hole of the triangle ladle 13 is arranged just above the slow inclining part 16, the sufficient total height H for flowing down is secured. Therefore, the dropping height (h) of the molten metal 17 can be reduced till it comes into contact with the chute 12. The contacting angle α between the molten metal 17 and the slow inclining part 16 is reduced by air stream 19 spouted from an air stream supplying pipe 18 and also, the air is enclosed in the surface between the molten metal 17 and the chute 12. Therefore, as the dropping height (h) is reduced and the contacting angle is reduced and the enclosement of the air is developed, shock of the flow-down of molten metal 17 is remarably reduced.
