Abstract

본 발명은 단일 진공 장치내에서 용해 탈가스 및 주조를 연속적으로 행하여 산소, 질소를 원활히 제거하기 위한 무산소등의 제조방법에 관한 것으로, 전기동을 도가니에서 유도 코일을 용해하고, 자기 교반함과 동시 상부가스 취입을 병행하여 용동중의 탈가스 및 환원 처리한 후 동일한 진공분위기에서 용동을 랜더에 흘러보내 주행에 주조항을 특징으로 하는 무산소동의 제조방법이다.The present invention relates to a process for producing anoxic, etc. for smoothly removing oxygen and nitrogen by continuously performing dissolution degassing and casting in a single vacuum apparatus. After degassing and reducing the molten gas in parallel with the blowing of gas, the molten oxygen is flowed into the renderer in the same vacuum atmosphere to produce an oxygen-free copper which is characterized by a casting term for traveling.
