Abstract

본 발명은 불활성가스 등을 용융금속중에서 미세화하고, 또 균일하게 확산시켜서 효율적으로 수소가스 및 비금속개재물을 제거하는 장치를 제공하는 것을 목적으로 한다.An object of the present invention is to provide an apparatus for minimizing inert gas and the like in molten metal and spreading it uniformly to efficiently remove hydrogen gas and non-metallic inclusions.

본 발명은 용융금속을 고이게 하는 처리통(14)과, 정역방향으로 회전 가능하며 선단부가 상기한 처리통내에 위치하고 있는 회전축(5),(6)과, 이 회전축의 선단부에 부착되어 있는 기포발생기(30)등으로 구성되어 있다. 기포발생기(30)는 일정시간마다 정역방향으로 반전하면서 용융금속내로 불활성가스를 분출하여 기포를 발생한다.The present invention relates to a processing cylinder (14) for pooling molten metal, rotating shafts (5) and (6) rotatable in the forward and reverse directions, and the tip of which is located in the processing cylinder, and a bubble generator attached to the leading end of the rotating shaft. And 30. The bubble generator 30 generates bubbles by injecting an inert gas into the molten metal while reversing in the forward and reverse directions every predetermined time.
