고로의 출선구 개공장치{APPARATUS FOR BORING TAP HOLE IN A BLAST FURNACE}Opening device for opening of blast furnace {APPARATUS FOR BORING TAP HOLE IN A BLAST FURNACE}

본 발명은 고로의 출선구 개공장치에 관한 것으로, 보다 상세하게는 고로 내부의 용융물을 배출시키기 위해 개공기로 출선구를 개공작업 하는데 있어서, 이 출선구 관통시 용융물과 동시에 출선구에서 다량으로 분출되는 분진을 고로 외부로 유출시키지 않고 고로의 출선구 개공장치에 의해 유출시키 수 있도록 한 고로의 출선구 개공장치이다.The present invention relates to an opening device for opening the blast furnace, and more particularly, in the opening of the exit opening with the opening to discharge the melt inside the blast furnace, when the penetration through the exit and ejected in large quantities at the same time with the melt It is a blast furnace opening device that allows dust to be discharged by the blast furnace opening device without releasing dust to the outside of the blast furnace.

일반적으로 고로(1) 조업은 철광석과 코크스를 일정한 비율로 고로(1) 상부로 장입하고 열풍로(미도시) 에서 생산된 고온의 열풍(1200℃)을 상기 고로(1) 환상관을 통해 고로(1)의 하부로 송풍함에 의해 상기 고로(1)에 장입된 철광석 및 코크스를 고온의 열풍(1200℃)과 용융, 환원 반응을 일으키게 하여 용선을 생산하게 된다.In general, the operation of the blast furnace (1) loads iron ore and coke at a predetermined ratio into the upper part of the blast furnace (1) and the hot blast (1200 ° C.) produced in a hot blast furnace (not shown) through the blast furnace (1) annular tube. By blowing to the lower part of (1), the iron ore and coke charged into the blast furnace 1 are caused to melt and reduce with hot hot air (1200 ° C.) to produce molten iron.

상기와 같이 생산된 용선을 고로(1) 외부로 배출시키는 작업을 출선 작업이라 하는데 이 출선작업은 다음과 같다.The operation of discharging the molten iron produced as described above to the outside of the blast furnace (1) is called a starting work, the drawing work is as follows.

먼저, 대탕도유동덮개(3)를 이 대탕도(8)로부터 취외하고 고로(1) 외부로 유출되는 분진을 포집하는 유출분진집진후드(4)를 후퇴시킨다.First, the large-scale water flow cover 3 is removed from this large-scale waterway 8, and the outflow dust collection hood 4 which collects the dust which flows out of the blast furnace 1 is retracted.

개공기(11)에 굴착비트(30)가 선단부에 부착된 굴착로드(13)를 장착하고, 개공기(11)를 선회하여 출선구(6)에 근접하게 위치시킨 후 상기 개공기(11)에 장착된 굴착로드(13)의 선단부 굴착비트(30)를 출선구(6)에 밀착시켜 굴착로드(13)를 정방향으로 회전시킨다.Mounting the excavating rod 13 attached to the distal end of the drilling bit 30 to the opening machine 11, and turning the opening machine 11 to be located close to the outlet 6, the opening machine 11 The tip end drilling bit 30 of the drilling rod 13 mounted in close contact with the exit port 6 to rotate the drilling rod 13 in the forward direction.

이후, 전진해머(미도시)를 이용하여 개공기몸체(12)를 서서히 전진시켜 출선구(6)를 굴착하며, 출선구(6)가 관통이 되면 상기 개공기몸체(12)를 후퇴 시키고 후진해머(미도시)를 기동하여 상기 개공기몸체(12)를 완전히 후퇴시킨다.Then, using the forward hammer (not shown) to slowly advance the opening body 12 to excavate the exit opening 6, when the opening 6 is penetrated retreat the opening body 12 and back A hammer (not shown) is activated to fully retract the opening body 12.

이후, 굴착로드(13)의 선단부 굴착비트(30)가 출선구(6)에서 빠져 나오면서 출선구(6)는 관통이 되며 이와 동시에 용융물(2)이 배출이 된다.Thereafter, the tip end drilling bit 30 of the excavation rod 13 exits from the outlet 6 and the outlet 6 is penetrated and at the same time the melt 2 is discharged.

상기 개공기(11)를 대기위치까지 이동시키고 이 개공기(11)가 일정한 지점 즉, 대탕도유동덮개(3)와 간섭이 되지않는 지점에서 대탕도유동덮개(3)를 머니퓰레이터(MANIPULATOR)(10)로 출선구댐퍼(7) 측으로 이동시키고 유출분진집진후드(4)를 전진시켜 출선구(6)에서 용융물(2)과 함께 발생되는 다량의 분진(9)을 분진흡입장치(미도시)로 유도한 후 상기 개공기(11)는 대기 위치로 이동되며 출선구(6)의 개공작업이 완료된다.The opener 11 is moved to a standby position, and the opener 11 is manipulator (MANIPULATOR) at a point where the opener 11 does not interfere with the opener cover 3. 10) by moving to the outlet damper (7) side and advancing the dust collector dust hood (4) to collect a large amount of dust (9) generated with the melt (2) at the outlet (6) dust suction device (not shown) After guided to the opening machine 11 is moved to the standby position and the opening work of the exit port (6) is completed.

상기와 같은 작업은 익일 10 ~ 15회 이상 반복적으로 출선구(6)에 개공작업을 실시한다.The work as described above is carried out to the opening port 6 repeatedly 10 to 15 times the next day or more.

그러나 상기 출선구(6) 개공작업 즉, 개공기(11)에 장착된 굴착로드(13)로 출선구(6)를 개공하여 용융물(2)이 배출되면 상기 개공기(11)를 일정지점까지 대피후 대탕도유동덮개(3)를 덮어 출선구(6) 개공이 완료되는 과정에서 다음과 같은 문제점이 있다.However, when opening the exit opening 6 with the excavation rod 13 mounted on the opening opening 11, that is, the molten material 2 is discharged, the opening opening 11 is opened to a predetermined point. There is the following problem in the process of opening the exit opening 6 by covering the Daetangdo flow cover 3 after evacuation.

첫째, 출선구(6)가 관통되어 용융물(2)이 배출되면서 다량의 분진이 동시 다발적으로 분출되는데 이분진은 대탕도유동덮개(3)를 덮기 전까지는 출선구(6) 측면의 분진흡입장치로 유도되지 않고 외부로 유출이되어 환경오염을 발생시킨다.First, a large amount of dust is ejected at the same time as the outlet 6 penetrates and the melt 2 is discharged. The dust is sucked into the dust on the side of the outlet 6 until the dust cover is covered. It does not lead to the equipment but leaks to the outside, causing environmental pollution.

둘째, 출선구(6) 개공작업시 대탕도유동덮개(3)를 개방하고 굴착하여용융물(2)을 배출시키는 관계로 비산된 용융물(2)에 의해 개공기(11)가 용손되며 개공작업자가 용융물(2)에 노출되어 고온의 용융비산물에 안전사고가 발생된다.Second, the opening machine 11 is melted by the melt 2 scattered due to the opening and excavation of the large water flow cover 3 and the excavation of the molten metal 2 during the opening of the exit opening 6, and the opening worker Exposure to the melt 2 causes safety accidents in the hot melt fly-bys.

본 발명은 상기와 같은 문제점을 해결하고자 창출한 것으로, 개공기에 장착된 굴착로드의 굴착비트를 분리시켜 개공기를 대기위치에 이동시킨 다음 대탕도유동덮개를 대탕도 상부에 위치시키고, 유출분진 집진후드를 유출분진집진댐퍼로 이동시킨 후 출선구를 관통하여 용융물을 배출할 수 있도록 한 고로의 출선구 개공장치를 제공함에 그 목적이 있다.The present invention has been created to solve the above problems, by separating the excavation bit of the excavation rod mounted in the open hole to move the open hole to the standby position and then placed the countertop flow cover at the top of the counter, dust spill The purpose of the present invention is to provide a factory for opening the outlet of the blast furnace for discharging the melt through the outlet after moving the dust collection hood to the outflow dust collector damper.

The stopper 36 stands in a single shape by the force of the stopper spring 31 which pushes the front end of the stopper 15 while being in contact with the starting hole, which is installed in the inner diameter square hole 35 of the drilling bit 30. Four stoppers (36) are operated simultaneously and the stopper spring (31) is designed to be larger than the elastic spring (19) embedded in the fixed ball (14-1) to operate when the opening body (12) retracted The detachable rod 14 and the drilling bit 30 are easily separated by BACK HAMMERING operation. The opening machine 11 is equipped with only the separate rod 14 and moves to the standby position (FIG. 7), and moves the manipulator 10, which is a device for collecting the large flowway cover 3 to the upper side of the large flowway 8, and outflow. When the dust collecting hood 4 is moved forward and the operation is completed, the hot air supply automatic valve 52 and the hot air discharge automatic valve 53 are opened in the control unit 100 so that high temperature hot air is introduced through the hot air supply pipe 42 and discharged. When the lead cylindrical set kit 39 is heated and the kite and thermometer 55 embedded in the outlet cylindrical set kit 39 become 800 ° C., it is in contact with the starting cylindrical set kit 39 and is in the outlet port 6. The fixed drilling bit 30 (iron transformation point 768 ° C.) is melted at the same time as heating and is melted by the internal melt 2 and at the same time the melt 2 is discharged by the pressure in the furnace, and the tapping-shaped cylindrical set smoke 39 is used. ) And the thermometer (55) built in the (800) when the 800 ℃ detection detects the hot air supply automatically from the control unit (100) The valve 52 and the hot air discharge automatic valve 53 are closed and the nitrogen automatic valves 57 and 59 are opened to purge the cooling water supply pipe 40 to purge the molten material through the outlet 6. ) When discharging, it protects the tap-hole cylindrical set lead 39 and the opening of the tap-hole 6 is finished.

이상에서 상세히 설명한 바와 같이, 본 발명은 출선구 개공작업시 출선구로부터 배출되는 고온의 용융물에 의해 작업자의 안전재해 발생을 방지하고 출선구로부터 배출되는 다량의 분진을 포집하여 유출분진집진댐퍼에서 전량 흡입하여 환경오염을 방지하고 고온의 용융물로부터 개공기의 용손을 방지하여 설비수명을 연장시켜 고로 안정조업할 수 있는 효과를 제공한다.As described in detail above, the present invention prevents the occurrence of safety accidents of workers by the high temperature melt discharged from the outlet at the time of opening of the outlet, and collects a large amount of dust discharged from the outlet, so that the total amount of the dust in the dust collector damper It prevents environmental pollution by inhalation and prevents melting of open air from high temperature melt, thus extending the life of equipment and providing stable operation of blast furnace.
