Abstract
A molten metal supplying container, comprising a container capable of storing a molten metal and loading the molten metal to the inside thereof or supplying the molten metal to the outside thereof by controlling a difference in pressure between inside and outside of the container, a passage allowing the inside and outside of the container to communicate with each other to have the molten metal flow therethrough, a lid disposed to cover the first opening having a second opening with a diameter smaller than the first opening and a hatch provided at the second opening capable of being opened and closed, having a passage communicating inside and outside the container. The passage is used, for example, to control inner pressure of the container and to insert the electrode for detecting the surface level of the molten metal.
