본 발명은 부원료 투입설비에 관한 것으로, 보다 상세하게는 부원료의 쏠림현상에 의해 이동로를 막은 부원료를 외부로 배출하지 않고 부원료 저장장치로 회수함으로서, 이동로를 막은 부원료를 작업상의 번거로움이나 시간상의 지연 없이 용이하게 분출시키는 동시에 분출된 부원료를 다시 회수하여 재활용가능하게 할 뿐만 아니라 부원료의 외부배출에 의한 환경오염을 방지할 수 있도록 한 방향전환수단을 구비한 부원료 투입설비에 관한 것이다.The present invention relates to a secondary raw material input equipment, and more particularly, by recovering the secondary raw material blocking the moving path to the secondary raw material storage device without discharging the secondary raw material blocking the moving path due to the phenomenon of the secondary raw material to the outside, in terms of work hassle or time The present invention relates to a subsidiary material input facility having a redirection means for easily discharging without retarding and at the same time recovering the subsidiary material to be recycled and preventing environmental pollution caused by external discharge of the subsidiary material.

일반적으로 전기로는 도 1에 도시된 바와 같이, 상부에 형성된 3상의 전극봉(a1)에 전류를 통하여 발생하는 아크(arc)열을 이용하여 스테인레스강 등을 생산하기 위한 것으로서, 전기로(A) 노벽의 국부적 침식을 방지 위하여 노벽을 코팅함 과 동시에 용탕의 적정 슬래그 조제에 의한 염기도 조성 위해 부원료(B,도 3참조)를 투입하게 된다.Generally, as illustrated in FIG. 1, an electric furnace (A) furnace wall is used to produce stainless steel using arc heat generated through an electric current to a three-phase electrode rod a1 formed at an upper portion thereof, as shown in FIG. 1. In order to prevent the local erosion of the coating of the furnace wall and at the same time to add a secondary material (B, see Fig. 3) to form the basicity by the preparation of the appropriate slag of the molten metal.

부원료(B)는 소량의 미분이 혼합된 미세괴상(통상 3mm ~ 6mm의 입자)으로서, 그 투입과정을 살펴보면, 상기 부원료(B)는 부원료저장장치(10)에 저장된 상태에서 부원료저장장치(10)의 하부에 구성된 챔버(11)에 투입 목표량만큼 재저장되고, 상기 투입목표량이 챔버(11)하부의 챔버곡관(12)으로 연속 공급되며, 상기 챔버곡관(12)으로 공급된 상태에서, 질소라인(13)을 통해 주입되는 질소의 분사압력에 의해 플렉시블호스(14)를 거쳐 부원료수송관(16)을 통해 전기로(A) 상부의 부원료투입홀(a2)로 수송되고, 상기 부원료투입홀(a2)을 통해 전기로(A) 내부로 투입되게 된다. Secondary raw material (B) is a fine mass (usually 3mm ~ 6mm particles) mixed with a small amount of fine powder, looking at its input process, the secondary raw material (B) is stored in the secondary raw material storage device 10 in the state of the secondary raw material storage device (10) In the state in which the target amount is re-stored in the chamber 11 configured at the lower part of), and continuously supplied to the chamber curved tube 12 below the chamber 11, and supplied to the chamber curved tube 12, nitrogen Nitrogen injected through the line 13 is transported to the sub-material input hole (a2) of the upper part of the electric furnace (A) through the flexible hose 14 through the sub-material transport pipe 16 by the injection pressure of nitrogen, the sub-material input hole Through (a2) is to be introduced into the electric furnace (A).

그러나 상기 과정에서 부원료는 곡선형태의 챔버곡관 내부에서 쏠림현상에 의해 이동로를 막게 되는 일이 빈번하게 발생하며 상기와 같이 부원료에 의해 이동로가 막힐 경우, 도 2에 도시된 바와 같이 고압의 질소가스를 이용하여 외부로 배출하는 방법과 도 3에 도시된 바와 같이 플렉시블호스(14)를 분리하여 부원료(B)를 제거하는 방법이 사용되고 있다.However, in the above process, the secondary raw materials frequently block the moving path due to the pulling phenomenon inside the curved chamber curved tube, and when the moving path is blocked by the secondary raw material as described above, high-pressure nitrogen is shown in FIG. 2.
