WIPO Patent Application WO/2011/118477

A1

The disclosed installation structure for a gas-injection plug is easy to maintain and can prevent a molten metal from leaking out via a gas-supply tube for supplying a gas to the gas-injection plug. In said installation structure, a bottom plate (12) is disposed so as to contact the bottom surface of a top plate (5) that supports the bottom section of a gas-supply tube (1d) for supplying a gas to a gas-injection plug (1). The bottom surface of the top plate (5) and the top surface of the bottom plate (12) form a space (14) that connects to the gas-supply tube (1d), and said space is connected to a gas-introduction channel (16).
