Abstract

코크스를 연료로 하는 큐폴라 등의 수직형 고속 용해로에 있어서 그 노체의 송풍구로의 송풍량을 투입되는 크스비를 연소시키기 위해서 필요한 이론 연소 산소량에 대해서 그 노체로의 송풍 공기중에 순산소의 추가량을 1% 내지 20%의 범위내에 있어서 임의로 가변해서 추가하는 것에 이해서 출탕량이 일정으로 출탕 온도의 변화를 제어할 수 있게 한다.In a vertical high-speed melting furnace such as a cupola fueled by coke, the amount of pure oxygen is added to the blowing air to the furnace with respect to the theoretical combustion oxygen amount required to burn the XS ratio to which the blowing amount to the blower of the furnace is injected. The amount of tapping can be controlled in a constant manner in addition to the variable addition in the range of% to 20%.
