More Information
Summary:Disclosed is an atomizing nozzle which prevents cooling of an orifice (tube) supplying molten metal and applies larger amount of impact on the molten metal compared to a conventional atomizing nozzle. The atomizing nozzle according to an embodiment comprises: an electrode unit that surrounds the orifice, from which the molten metal spouts, and has an internal flow passage which provides a moving path of operating gas, wherein an arc is generated inside the flow passage; a body unit which surrounds the electrode unit and supplies the operating gas and electric energy to the electrode unit; and a head unit which is engaged with the lower part of the body unit. The flow passage is formed between the body unit and the head unit to supply cooling liquid to the lower part of the orifice. 용융금속을 공급하는 오리피스(튜브)의 냉각을 방지하고, 종래에 아토마이징 노즐에 비하여, 용융금속에 큰 충격량을 가할 수 있는 아토마이징 노즐을 개시한다. 실시예에 따른 아토마이징 노즐은 용융금속이 분출되는 오리피스를 둘러싸고, 내부에 작동가스의 이동경로를 제공하는 유로가 구비되어 있고, 상기 유로에서 아크가 발생하도록 구성된 전극부; 상기 전극부를 둘러싸고, 상기 전극부에 작동가스와 전기에너지를 공급하는 몸체부; 및 상기 몸체부의 하부에 결합되는 헤드부 - 상기 몸체부와 상기 헤드부 사이에는 상기 오리피스의 하부로 냉각유체를 공급되도록 하는 유로가 형성됨 - ;를 포함한다.
