PURPOSE:To perfectly prevent the involution of air, especially, at the time molten slat is injected in a heating furnace, where a molten substance in a hermetically sealed container through the molten substance receiver placed on the hermetically sealed container in a hermetically sealed state, by specifically regulating the molten substance receiver to a state of always storing the molten substance. CONSTITUTION:For example, when molten slag is injected in a heating furnace, firstly a molten substance ladle is inclined and the molten slag is injected in a molten substance receiver 3. Subsequently, a detection means detects that the discharge port 3 of the molten substance receiver 3 is sufficiently sealed by the molten slag and the detection signal is sent to a drive mechanism 10. Hereupon, the drive mechanism 10 raises a stopper 8 to inject the molten slag in a hermetically sealed container 4 from a discharge port 5. When the level of the molten slag in the molten substance receiver 3 is lowered by said injection, the stopper 8 is allowed to fall before the discharge port 5 is exposed to stop the outflow of the molten slag. Then, the molten slag is again injected in the molten substance receiver 3 from the molten substance ladle and, when the molten slag is stored in a sufficient quantity, the stopper 8 is again raised to reopen the injection of the molten slag. |
