A steel ladle drainage method, is achieved by using a steel ladle structure. Vacuum interlayers are provided within an upper nozzle, an upper fixed plate, alower fixed plate and a sliding plate of the steel ladle structure respectively. In the steel ladle drainage method provided by the present invention, a metal drainage agent is used to replace the drainage sand in the prior art, the metal drainage agent is melted by the liquid steel and deposited in the upper nozzle, the sliding plate with the vacuum interlayer and the upper nozzle with the vacuum interlayer have the insulation effect on the melted metal drainage agent, agent falling. Moreover, through moving the sliding plate, the two pouring holes of the upper and lower fixed plates are connectedwith each other, the metal drainage agent enters the tundish through the pouring holes and the lower nozzle under the action of gravity.

A melt transportation apparatus according to an embodiment of the present invention comprises: a container having an internal space in which melt can be accommodated and an opening through which the melt can be input/output; a cover part which has a cover member capable of closing the opening and which is positioned at the top of the container so as to be movable forward/backward with respect to the opening; and a support part having a rotary body, which can move forward/backward with respect to the cover part at the bottom of the cover part so that the support part can be in contact with the cover part. Therefore, according to embodiments of the present invention, the opening of the container can be easily opened/closed in a limited space. In addition, when the opening is opened/closed by moving the cover part, sagging or tilting of the cover part can be prevented. Thus, the cover part can be easily moved and exposure of at least a portion of the opening to the outside can be prevented. Therefore, a decrease in the temperature of the melt inside the container can be prevented or suppressed.
