Description
본 발명은 용광로 스키머의 용선 차단장치에 관한 것으로서, 더욱 상세하게는 용광로의 출선구 폐쇄 후 대탕도에 고인 용선이 용선탕도로 흘러가는 것을 원격으로 차단함으로서, 작업자를 비산되는 용선으로부터 보호할 수 있도록 한 것이다.The present invention relates to a molten iron blocking device of the furnace skimmer, and more particularly, by remotely blocking the flow of the deceased molten iron to the molten iron after closing the outlet of the blast furnace, so as to protect the worker from flying molten iron. It is.
일반적으로, 용광로 내부에서 환원 용융된 용융물은 출선구를 통해 대탕도(60)에서 용선탕도(70)로 흘러 간다. 또한, 상기 대탕도(70)에는 용융물을 슬라그와 용선으로 분리하는 스키머(5)가 구비되어 있으며, 용융물이 대탕도(70)를 흘러가면서 오물질의 투입을 방지하는 후드(25)가 안착된다. 배출된 용융물은 스키머(5)에 의해 슬라그와 용선으로 분리되는데 이때, 슬라그는 배재구(50)를 통해 수재로, 용선은 2블럭(80)을 타고 용선탕도(70)를 거쳐 용선차(TLC)로 수선된다.In general, the melt melt reduced in the furnace flows from the large bath 60 to the molten metal 70 through the tap. In addition, the large bathway 70 is provided with a skimmer 5 for separating the melt into slag and molten iron, and the hood 25 for preventing the inflow of dirt while the melt flows through the large bath 70 is seated. do. The discharged melt is separated into slag and molten iron by the skimmer (5), in which slag is the water through the outlet 50, the molten iron rides the two blocks (80) and the molten iron through the molten iron (70) Repaired by (TLC).
그리고, 출선작업을 마친 후에는 대탕도(60)에 잔류하는 용선의 흐름을 차단하여 다음번 출선 조업의 준비를 하게된다.Then, after finishing the drawing work, the flow of the molten iron remaining in the large bathway 60 is cut off to prepare for the next drawing operation.
따라서, 도 1에 나타난 바와같이, 작업자가 직접 대탕도와 용선탕도의 경계지점인 2블럭(80)주위에서 용선차단 모래(15)를 삽으로 적치하여 용선의 흐름을 차단하게 된다.Therefore, as shown in FIG. 1, the worker directly blocks the molten iron blocking sand 15 with a shovel around the second block 80 which is the boundary point between the large hot water and the molten iron.
그러나, 상기와 같은 수작업에 의한 조업은 용선의 흐름을 제 때에 차단하기 어렵고, 이에따라, 탕도 낙구나, 경주통의 용선응고로 다음 출선작업시 용선 유출사고와 설비 작동 불능등 제반설비 사고 발생을 초래하였다.However, it is difficult to shut off the flow of molten iron in a timely manner as described above, and therefore, it is difficult to shut down the flow of molten iron in a timely manner. Caused.
또한, 조업시 비산되는 용선으로 부근에서 조업중이던 작업자들의 재해로 이어져 막대한 인적,물질적 손실을 유발하였다.In addition, the chartered planes were scattered during operation, leading to disasters of workers operating nearby, causing huge human and material loss.
본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 대탕도와 용선탕도의 경계지점인 2블럭에 원격으로 용선차단 모래를 적치할수 있도록 하여, 출선작업 후의 대탕도에 잔류하는 용선 흐름을 차단할때 발생되는 탕도 낙구나, 경주통의 용선응고로 인한 사고발생을 미연에 방지하며, 또한, 조업시 비산되는 용선으로부터 작업자들을 안전하게 보호할 수 있는 용광로 스키머의 용선 차단장치를 제공함에 그 목적이 있다.The present invention is to solve the above problems, it is possible to remotely accumulate the molten iron blocking sand in the two blocks which is the boundary point between the large hot water and the molten iron, also occurs when blocking the flow of the molten iron remaining in the large water after the embarking work The object of the present invention is to provide a molten metal blocker for a furnace skimmer that can prevent accidents due to molten iron falling down and molten iron in the raceway, and to protect workers from molten iron scattered during operation.

상기와 같은 목적을 달성하기 위한 본 발명의 기술적 사상은, 대탕도와 용선탕도의 경계지점의 상방에 위치하는 스키머 후드에 용선차단 모래를 구비할 수 있는 호퍼를 형성하고, 상기 호퍼의 배출구를 원격으로 개폐할 수 있도록 공압실린더로 작동되는 댐퍼를 호퍼에 설치함을 특징으로 한다.The technical idea of the present invention for achieving the above object is to form a hopper that can be provided with the molten iron blocking sand in the skimmer hood located above the boundary point between the large hot water and molten iron, and the outlet of the hopper is remote A damper operated by a pneumatic cylinder so as to be opened and closed by the hopper is characterized in that it is installed.
이하, 본 발명에 따른 바람직한 실시예를 첨부된 도면에 따라 보다 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.
도 2는 본 발명에 따른 차단장치가 스키머 후드에 설치된 상태를 나타내는 도면이다.2 is a view showing a state in which the blocking device according to the invention is installed in the skimmer hood.
도면에 도시된 바와 같이, 대탕도(60)와 용선탕도(70)의 경계지점 즉, 2블록(80)의 상방에 안착된 후드(25)의 일측에 용선차단 모래(15)를 구비한 호퍼(10)가 부설된다.As shown in the figure, the molten iron blocking sand 15 is provided at a boundary point between the large bathway 60 and the molten iron bath 70, that is, one side of the hood 25 seated above the two blocks 80. Hopper 10 is placed.
상기 호퍼(10)의 양측에는 공압으로 제어되는 실린더(20)가 설치되고, 상기 실린더(20)의 일단은 회동가능하도록 힌지로 고정되며, 타단은 힌지체결 가능한 체결구로 형성된다.Pneumatically controlled cylinders 20 are installed at both sides of the hopper 10, one end of the cylinder 20 is fixed to the hinge to be rotatable, and the other end is formed as a hinge fastener.
그리고, 호퍼(10)의 배출구를 개폐하는 댐퍼(40)가 공압실린더(20)의 하방 일정영역에서 회동가능하도록 고정되는 댐퍼아암(30)과 연설된다.Then, the damper 40 for opening and closing the outlet of the hopper 10 is spoken with the damper arm 30 fixed to be rotatable in a predetermined region below the pneumatic cylinder 20.
상기 댐퍼아암(40)은 상기 공압실린더(20) 타단의 체결구와 체결된다.The damper arm 40 is engaged with a fastener at the other end of the pneumatic cylinder 20.
도 3는 본 발명에 따른 차단장치의 단면을 나타내는 도면이다.3 is a view showing a cross section of the blocking device according to the present invention.
상기 호퍼는 도면에 도시된 바와 같이 상방은 개구되어 있어, 필요시마다 용선차단 모래(15)를 재공급할 수 있다.As shown in the figure, the hopper is open upward, and can re-supply the molten iron-blocking sand 15 as needed.
본 발명에 따른 작동상태를 도면에 의거 설명한다.The operation state according to the present invention will be described with reference to the drawings.
도 4는 공압실린더(20)의 작동에 따른 용선차단 모래(15)가 호퍼(10)에서 배출되는 것을 나타내는 도면이다.4 is a view illustrating that the molten iron blocking sand 15 is discharged from the hopper 10 according to the operation of the pneumatic cylinder 20.
도면에 도시된 바와같이, 출선작업후 절환변(미도시)에서 제어된 공압실린더(20)의 타단은 댐퍼아암(30)을 당기게 되어 댐퍼아암(30)의 타단에 부설된 댐퍼(40)를 댐퍼아암(30)의 일단을 중심으로 회동하여 호퍼(10)의 배출구에서용선차단 모래(15)를 2블록(80)에 적치하게 되어 용선의 흐름을 차단할 수 있다.As shown in the figure, the other end of the pneumatic cylinder 20 controlled in the switching valve (not shown) after the unloading operation pulls the damper arm 30 to the damper 40 attached to the other end of the damper arm 30 By rotating about one end of the damper arm 30, the molten iron blocking sand 15 is deposited in the two blocks 80 at the outlet of the hopper 10 to block the flow of the molten iron.
이상에서 설명한 바와 같이, 본 발명에 따른 용광로 스키머의 용선 차단장치는 원격으로 용선차단 모래를 2블록에 적치할 수 있게 됨으로써, 적시에 용선의 흐름을 차단할 수 있으며, 작업자가 차단작업을 현장에서 직접하지 않으므로 용선차단 모래적치시 비산되는 용선으로부터 작업자를 보호할 수 있어 재해의 발생을 사전에 방지할 수 있는 것이다.As described above, the molten iron blocker of the furnace skimmer according to the present invention can remotely accumulate molten iron in two blocks, it can block the flow of molten iron in a timely manner, the operator directly cut off the work on the site As it does not, it is possible to protect workers from the molten iron that is scattered when the molten iron is blocked, so that the occurrence of a disaster can be prevented in advance.
또한, 본 고안은 기재된 실시예에 한정하는 것이 아니고, 본 고안의 기술적 사상 및 범위를 벗어나지 않고 다양하게 수정 및 변형을 할수 있음은 이 기술 분야에서 통상의 지식을 가진 자에게는 자명하다.In addition, the present invention is not limited to the embodiments described, it is apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention.
