Abstract
In a sliding gate, a flow path vertical angle a between a flow path axial direction and a vertical downstream direction in a flow path hole in each plate is 5° or more and 75° or less, and a flow path axial direction projected on sliding surface in which the flow path axial direction is projected on a sliding surface differs between the plates and is changed clockwise or counterclockwise toward a downstream side. Then, molten metal forms a turning flow in the flow path hole of the sliding gate. Furthermore, the molten metal also forms a turning flow in a ladle shroud on the downstream side of the sliding gate.
