Description

슬랙의 이월을 최소로 하는 방법.How to minimize carry over of slack.

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 용광로 탭구멍을 통해 용융금속을 배출시키기 위해 태핑위치로 기울인 용광로의 단면도로서 부동스토퍼의 위치가 나타나 있다.FIG. 1 is a cross-sectional view of the furnace inclined to the tapping position for discharging molten metal through the furnace tap hole, showing the position of the floating stopper.

제2도는 부동스토퍼가 탭구멍에 어떻게 놓이나를 나타낸 약도이다.2 is a diagram showing how the floating stopper is placed in the tapped hole.

Claims (4)

탭구멍을 통해 용광로로 부터 용융금속을 배출함에 있어 슬랙이월을 최소로 하는 방법에서 이방법은 상기 용융금속과 슬랙의 중간정도의 밀도를 가지며 상기 탭구멍 개구 횡단 최대면적 보다 더 큰 최소 횡단면적을 갖는 동체를 탭구멍 위쪽 구역 내의 용융금속과 슬랙의 계면상에 적하시키고 용융금속을 탭구멍 개구를 통해 용광로로부터 배출시킨 다음, 용광로로 부터 이미 탭핑된 용융금속위로 슬랙이 이월되는 것을 막기 위해 탭구멍을 통한 흐름을 차단시켜 주는 것으로 구성되며 여기서 상기 동체는 등변 이란적으로 평면을 가지며 그의 교점은 상기 동체가 상기 탭구멍개구에 머물때 탭구멍개구의 20―80%가 차단되도록 탭구멍내 있게끔 적용됨을 특징으로 하며 이 방법은 상기 동체가 탭구멍에 머물때 상기 흐름의 플레어 징후가 보이도록 상기 탭구멍으로 부터 흘러나오는 흐름의 상태를 감시하는 것을 포함하는 슬랙이월을 최소로 하는 방법.In the method of minimizing slack carryover in discharging molten metal from the blast furnace through the tap hole, this method has a minimum cross-sectional area which is about the density of the molten metal and the slag and is larger than the maximum cross-sectional area of the tap hole opening. A fuselage with a drop is placed on the interface between the molten metal and the slag in the upper region of the tapped hole, and the molten metal is discharged from the furnace through the tap hole opening, and then the tap is pressed to prevent the slag from being carried over the molten metal already tapped from the furnace. Blocking the flow through the hole, wherein the fuselage has an isosceles plane and its intersection is such that 20-80% of the tap hole opening is blocked when the fuselage stays at the tap hole opening. The method is characterized in that the flare of the flow is visible when the body remains in the taphole. How the slack, which comprises monitoring the state of the flow coming out from the holes of the month as a minimum. 제1항에 있어서, 상기 동체가 다면체인 방법.The method of claim 1 wherein said fuselage is a polyhedron. 제2항에 있어서, 상기 동체가 입방체인 방법.The method of claim 2, wherein the fuselage is a cube. 제3항에 있어서, 상기 동체가 정육면체인 방법.The method of claim 3, wherein the fuselage is a cube. ※참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is to be disclosed based on the initial application.
