Description
본 고안은 고로의 열풍유량제어변에 관한 것으로, 특히 열풍로에서 생성된 열풍을 고로내로 공급하는 열풍관에 설치되면서 송풍량을 로황에 따라 인위적으로 조정할 수 있는 고로의 열풍유량제어변에 관한 것이다.The present invention relates to a hot air flow control valve of the blast furnace, and more particularly to a hot air flow control valve of the blast furnace that can be artificially adjusted according to the furnace sulfur while being installed in the hot air pipe for supplying the hot air generated in the hot blast furnace into the blast furnace.
일반적인 고로조업은 열풍로에서 생성되는 1200℃이상의 고온과 4.0㎏/㎠이상 고압의 열풍를 송풍지관(환상관, 열풍관, 열량유량제어변, 블로어파이프, 풍구, 대풍구 등의 총칭)을 통해 로내로 약200 ㎧이상의 고속으로 불어넣는다.In general, the blast furnace operation uses the hot air of more than 1200 ℃ and the high pressure of more than 4.0㎏ / ㎠ generated by the hot blast furnace through the blower pipe (annular pipe, hot air pipe, calorie flow control valve, blower pipe, blowhole, large blowhole, etc.). It is blown in at a high speed of about 200㎧ or more into.
고로조업은 이러한 송풍지관류가 20∼40개소가 잇어 조업에 대응하고 있으며, 그 중 열풍유량제어변은 송풍량을 인위적으로 변화시켜 로내의 원주방향별 가스흐름이나 로열불균형을 해소하며, 로벽부착물의 탈락을 유도하거나 로저내화물의 침식을방지하는 제어기술로 활용되고 있다.In the blast furnace industry, there are 20 to 40 places of blow-through perfusion, and among them, the hot air flow control valve artificially changes the air flow to solve the gas flow and the heat imbalance in the circumferential direction of the furnace. It is used as a control technology to induce dropout or prevent erosion of Roger refractory.
그러나, 도1에 도시한 바와같이 종래의 열풍유량제어변(60)은 고로조업 특성상 120。경사로 설치된 송풍지관(50,55,65,70)과 다단계 플랜지결합(50-1,55-1,60-1,65-1)되어 점검 및 정비시 분해와 조립에 과다한 시간이 소요되어 작업의 생산성을 떨어뜨리게 된다.However, as shown in FIG. 1, the conventional hot air flow control valve 60 has a blower tube 50, 55, 65, 70 installed at an inclination of 120 ° due to the blast furnace operation characteristics, and a multi-stage flange coupling 50-1, 55-1, 60-1,65-1), it takes too much time to disassemble and assemble during inspection and maintenance, which reduces the productivity of work.
본 고안은 변체 및 축수부가 탈부착이 용이한 조립식으로 제작되어 분해정비 및 점검시 다단계의 플랜지결합구조를 가지는 송풍지관을 해체하지 않고서 수리작업이 가능한 고로의 열풍유량제어변을 제공함에 그 목적이 있다.The object of the present invention is to provide a hot air flow control valve of a blast furnace that can be repaired without disassembling the blower pipe having a multi-stage flange coupling structure during disassembly, maintenance, and inspection. .
