Zusammenfassung:PURPOSE: A top bunker for blast furnace is provided in which two-step inclined cone is mounted to uniformize discharge speed of charging materials from the top bunker into blast furnace so that not only blast furnace operation is stabilized, but also productivity of hot metal is improved. CONSTITUTION: In a top bunker for blast furnace for finally supplying charging materials charged into blast furnace in blast furnace process, the top bunker for blast furnace is characterized in that a two-step inclined cone an inclination angle of upper and lower parts of which is different from each other is mounted on the inner part of the top bunker, the inclination angle of the upper part of the two-step inclined cone is set up in such a way that a funnel flow(8) of charging materials is formed by the inclination angle of the upper part of the two-step inclined cone, the inclination angle of the lower part of the two-step inclined cone is set up in such a way that a mass flow(7) of charging materials is formed by the inclination angle of the lower part of the two-step inclined cone, and the maximum reduction of storage volume of the top bunker by mounting of the two-step inclined cone does not exceed 2/3 of storage volume margin of the top bunker, wherein an inclination angle of the upper part of the two-step inclined cone is 50 to 60 degrees of an angle while an inclination angle of the lower part of the two-step inclined cone is 70 degrees or more of an angle. 본 발명은 고로 공정에서 노내에 장입되는 장입물을 최종적으로 공급하는 고로용 노정 벙커에 관한 것으로서, 고로로의 장입물 배출속도를 보다 균일화할 수 있는 고로용 노정벙커를 제공하고자 하는데, 그 목적이 있다. .본 발명은 고로 공정에서 노내에 장입되는 장입물을 최종적으로 공급하는 고로용 노정 벙커에 있어서, 상기 노정 벙커 내부에 그 상,하부의 경사각이 다른 2단 경사 콘을 장착하고; 그리고 상기 2단 경사 콘의 상부의 경사각은 장입물의 후로가 훠넬 후로를 이루도록 설정되고, 그리고 상기 2단 경사 콘의 하부의 경사각은 장입물의 후로가 매스 후로를 이루도록 설정되는 고로용 노정 벙커를 그 요지로 한다.
