Abstract
본 발명은 구상흑연 주철을 제조하기 위하여 구상화시키는 방법에 관한 것으로, 좀더 구체적으로는 구상화 처리제(2)를 담은 밀폐된 철제 용기(5)를 래들(1)에서 용탕(4)과 반응시켜 구상화 처리하는 방버에 관한 것이다.The present invention relates to a method for spheroidizing to produce spheroidal graphite cast iron, and more specifically, spheroidizing treatment by reacting a closed iron container (5) containing a spheroidizing agent (2) with a molten metal (4) in a ladle (1). It is about how to do.
본 발명에 의하여 처리제(2)를 철제용기(5)에 담아 사용하므로서 구상화 처리 전용 래들 및 커버제를 사용치 않으므로 생산성 및 생산원가가 절감되며, 또한 구상화 처리제(2)의 보관이 용이하고 수분등에 의해 구상화 처리제(2)의 변질이 방지되고, 다른 첨가 원소와의 혼합이 방지되어 재질 개선 및 작업이 안전성이 확보되었다.By using the treatment agent (2) in the steel container (5) according to the present invention, because no ladle and cover agent for spheroidizing treatment is used, productivity and production cost are reduced, and also the storage of the spheroidizing treatment agent (2) is easy, As a result, deterioration of the spheroidizing treatment agent 2 is prevented, and mixing with other additive elements is prevented, thereby improving material quality and ensuring safety in operation.
