Description

싱크롤의 양단 지지장치Support device for both ends of sink roll

본 고안은 싱크롤의 양단 지지장치에 관한 것으로, 특히 싱크롤의 양단축을 베어링에 의해 회전 가능하도록 지지하면서 베어링의 용융아연침적을 차단함으로써 싱크롤의 수명을 연장할 수 있는 싱크롤의 양단 지지장치에 관한 것이다.The present invention relates to a support device for both ends of the sink roll, and in particular, to support both ends of the sink roll so as to be rotatable by the bearing, and to support both ends of the sink roll which can extend the life of the sink roll by blocking the molten zinc deposition of the bearing. Relates to a device.

일반적으로, 도1에 도시한 바와같이 용융아연포트(1)내에는 480℃의 용융아연(6)이 담겨져 있고, 이 용융아연에 싱크롤(2)이 도2에 도시한 바와같이 일체형 지지구조물에 의해 지지된 상태로 침적되어 있다.In general, as shown in FIG. 1, the molten zinc port 1 contains molten zinc 6 at 480 DEG C. The molten zinc has a sink roll 2 having an integral support structure as shown in FIG. It is deposited in a state supported by.

이때, 텐션을 지닌 스트립(3)은 싱크롤(2)에 감긴 상태로 방향전환되어 진행되면서 표면에 아연도금이 이루어 진다.At this time, the strip (3) having a tension is made of zinc plating on the surface of the sink roll (2) while the direction is changed to proceed.

한편, 스트립(3)과의 접촉에 의해 회전되는 싱크롤(2)의 양단축(2-1)은 각각 부시(8)와 슬리브(7)에 의해 지지되고, 큰 면압으로 면접촉된 상태로 회전되는 싱크롤축(2-1)과 부시(8), 슬리브(7)에는 아연침식이 급격히 진행된다.On the other hand, both end shafts 2-1 of the sink roll 2 rotated by the contact with the strip 3 are supported by the bush 8 and the sleeve 7, respectively, and are in surface contact with a large surface pressure. Zinc erosion rapidly progresses on the rotating sink roll shaft 2-1, the bush 8, and the sleeve 7.

따라서, 싱크롤축(2-1)의 부시(8)와 슬리브(7)에 아연침식이 심화되면 싱크롤(2)자체의 진동이 과대해지고, 결국 싱크롤 전체를 교환하여야 하는 문제가 발생된다.Therefore, when zinc erosion is intensified in the bush 8 and the sleeve 7 of the sink roll shaft 2-1, the vibration of the sink roll 2 itself becomes excessive, resulting in a problem that the entire sink roll must be replaced.

또한, 싱크롤축(2-1)의 부시(8)와 슬리브(7)에 발생되는 아연침식과 마모과정에서 슬리브와 부시의 미세한 철분입자가 용융아연에 혼재되어 스트립(3)의 도금불량을 유발하게 된다.In addition, during the zinc erosion and abrasion occurring in the bush 8 and the sleeve 7 of the sink roll shaft 2-1, fine iron particles of the sleeve and the bush are mixed in the molten zinc, causing plating failure of the strip 3. Done.

본 고안은 싱크롤의 양단축을 베어링에 의해 회전 가능하도록 지지하면서 베어링의 용융아연침적을 차단함으로써 싱크롤의 수명을 연장할 수 있는 싱크롤의 양단 지지장치를 제공함에 그 목적이 있다.The object of the present invention is to provide a support device for both ends of the sink roll which can extend the life of the sink roll by blocking the molten zinc deposition of the bearing while supporting both ends of the sink roll to be rotatable by the bearing.

도면을 참조하여 본 고안의 구성을 설명한다.The configuration of the present invention will be described with reference to the drawings.

도4는 본 고안에 따른 싱크롤의 양단 지지장치가 장착된 지지구조물을 나타내는 사시도이고, 도5는 본 고안에 따른 싱크롤의 양단 지지장치를 나타내는 도4의 Y-Y단면도이며, 도6은 본 고안에 따른 싱크롤의 양단 지지장치중 밸브부를 나타내는 단면도이다.Figure 4 is a perspective view showing a support structure equipped with both ends of the sink roll support device according to the present invention, Figure 5 is a YY cross-sectional view of Figure 4 showing the support device for both ends of the sink roll according to the present invention, Figure 6 is the present invention It is sectional drawing which shows the valve part of the both ends support apparatus of the sink roll.

싱크롤(3)의 양측에 설치되는 사각박스형의 베어링본체(9)에는 중앙에 각각 2차보호격실(11)이 형성되어 있고, 안쪽면에 1차보호격실(10)이 형성되어 있으며, 싱크롤축(3-1)의 양단이 각각 1차보호격실(10)을 관통하여 2차보호격실(11)에 베어링(25)에 의해 지지되도록 내장되어 있다.The secondary protective compartment 11 is formed in the center, and the primary protective compartment 10 is formed in the center, respectively, in the square box-shaped bearing body 9 installed on both sides of the sink roll 3, and the sink Both ends of the roll shaft 3-1 penetrate the primary protective compartment 10, respectively, and are embedded in the secondary protective compartment 11 so as to be supported by the bearing 25.

이때, 본체(9)와 싱크롤축(3-1) 사이를 통해 유입되는 용융아연(6)을 최소화하기 위하여 질소가스가 충전되는 1차보호격실(10)에는 상부측에 가스공급관(12-1)이 연결되면서 측면 하부측에 가스배출관(12-2)이 연결되어 있다.At this time, in order to minimize the molten zinc (6) flowing through the main body 9 and the sink roll shaft (3-1) in the primary protective compartment (10) filled with nitrogen gas gas supply pipe (12-1) ) And the gas discharge pipe 12-2 is connected to the lower side of the side.

또한, 1차보호격실(10)의 하부에는 아연배출구(10-1)가 형성되어 1차보호격실(10)내에 충전된 아연을 본체(9)의 하부측으로 배출하게 된다.In addition, a zinc discharge port 10-1 is formed in the lower portion of the primary protective compartment 10 to discharge zinc charged in the primary protective compartment 10 to the lower side of the main body 9.

여기서, 가스공급관(12-1)과 가스배출관(12-1)에 연결되는 가스라인(12)은 외부에서 질소가스를 공급받아 본체(9)내의 온도에 의해 충분히 예열될 수 있도록 입구측이 코일형으로 감겨져 있다.Here, the gas line 12 connected to the gas supply pipe 12-1 and the gas discharge pipe 12-1 is coiled at the inlet side so that nitrogen gas is supplied from the outside to be sufficiently preheated by the temperature in the main body 9. It is wound in a mold.

그리고, 가스공급관(12-1)을 통해 1차보호격실(10)내로 충전되는 질소가스는 용융아연(6)의 온도보다 낮게 유지되면서 1차보호격실내의 압력을 용융아연의 유입압력보다 높도록 유지시킴으로써 본체(9)와 싱크롤축(3-1) 사이를 통한 용융아연(6)의 유입을 최소화하게 된다.In addition, the nitrogen gas charged into the primary protective compartment 10 through the gas supply pipe 12-1 is kept lower than the temperature of the molten zinc 6 while the pressure in the primary protective compartment is higher than the inlet pressure of the molten zinc. In order to minimize the inflow of the molten zinc 6 between the main body 9 and the sink roll shaft 3-1, it is minimized.

또한, 2차보호격실(11)의 후방측면에는 상하측에 각각 냉각가스인입관(18)과 냉각가스회수관(19)이 연결되어 있고, 냉각가스회수관보다 작은 직경의 냉각가스인입관은 입구측이 냉각가스회수관에 내장되어 있어 본체(9)내의 고열과 질소냉각가스의 접촉을 차단하게 된다.In addition, the cooling gas inlet pipe 18 and the cooling gas recovery pipe 19 are connected to the rear side of the secondary protective compartment 11 at the upper and lower sides, respectively. The inlet side is embedded in the cooling gas recovery tube to block the contact between the high heat and the nitrogen cooling gas in the main body 9.

한편, 본체(9)는 하부 바닥이 원추형으로 경사지게 형성되어 있어 1차보호격실(10)의 아연배출구(10-1)를 통해 배출되는 아연이 중앙에 모이게 되고, 본체의 하부 중앙에는 밸브가이드관(9-1)이 형성되어 있다.On the other hand, the main body 9 is formed in the bottom of the inclined inclined conical so that the zinc discharged through the zinc outlet (10-1) of the primary protective compartment 10 is collected in the center, the valve guide pipe in the lower center of the main body (9-1) is formed.

그리고, 밸브가이드관(9-1)의 내주면 상부에는 밸브시트관(28)이 부착되어 있고, 아연포트(1)내의 용융아연(6)의 부력에 의해 뜨도록 설계된 첵볼(16)은 밸브가이드관(9-1)내를 상하이동되면서 밸브시트관(28)의 하부를 개폐하게 된다.In addition, a valve seat tube 28 is attached to an upper portion of the inner circumferential surface of the valve guide tube 9-1, and the ear ball 16, which is designed to float by buoyancy of the molten zinc 6 in the zinc port 1, has a valve guide. The lower portion of the valve seat tube 28 is opened and closed while moving inside the tube 9-1.

이때, 밸브가이드관(9-1)의 외주면 하단부에 부착되는 밸브본체(15)는 내부에 용융아연(6)이 항상 충전되어 있도록 개방되어 있고, 본체(9)의 내부압력에 의해 밸브가이드관을 따라 하강되는 첵볼(16)이 이탈되는 현상을 방지하게 된다.At this time, the valve body 15 attached to the lower end of the outer circumferential surface of the valve guide pipe 9-1 is opened so that the molten zinc 6 is always filled therein, and the valve guide pipe is driven by the internal pressure of the main body 9. It is to prevent the phenomenon that the ear ball 16 that is lowered along the separation.

또한, 수위검출스위치(17)는 2차보호격실(11)의 하부에 설치되면서 본체(9)의 하부에 모이는 용융아연(6)의 최고 또는 최저수위를 측정하여 제어기(20)에 신호 송출을 하게 된다.In addition, the water level detection switch 17 is installed in the lower portion of the secondary protective compartment 11 and measures the highest or lowest water level of the molten zinc 6 collected in the lower portion of the main body 9 to send a signal to the controller 20. Done.

여기서, 수위검출스위치(17)와 제어기(20) 사이를 연결하는 케이블(17-1)은 냉각가스인입관(18)내를 통하여 연결됨으로써 고열에 의한 통전방해를 방지하게 된다.Here, the cable 17-1 connecting between the water level detection switch 17 and the controller 20 is connected through the cooling gas inlet pipe 18 to prevent the energization of the high heat.

이하, 본 고안의 작용을 설명한다.Hereinafter, the operation of the present invention.

초기단계에서 가스공급관(12-1)을 통해 공급되는 질소가스를 이용하여 1차보호격실(10)의 내압을 아연포트(1)의 용융아연(6)의 압력 이상으로 유지하고, 본체(9)의 전체내압을 아연포트(1)의 용융아연(6)의 압력 이하로 유지한다.In the initial stage, the internal pressure of the primary protective compartment 10 is maintained above the pressure of the molten zinc 6 of the zinc pot 1 by using nitrogen gas supplied through the gas supply pipe 12-1, and the main body 9 ), The total internal pressure is maintained below the pressure of the molten zinc (6) of the zinc pot (1).

이때, 압력검출센서(22)에서 1차보호격실(10)의 내압을 측정하여 증폭기(23)를 통해 제어기(20)에 송출하면 제어기에서 압력조정기(24)를 통해 계속적으로 1차보호격실의 내압을 제어하게 된다.At this time, when the pressure detection sensor 22 measures the internal pressure of the primary protective compartment 10 and sends it to the controller 20 through the amplifier 23, the controller continuously controls the primary protective compartment through the pressure regulator 24. To control the internal pressure.

여기서, 1차보호격실(10)의 질소가스압력에도 불구하고 용융아연(6)이 본체(9)와 싱크롤축(2-1) 사이를 통해 유입되면 아연배출구(10-1)를 통해 본체의 바닥에 집수된다.Here, in spite of the nitrogen gas pressure of the primary protective compartment 10, when the molten zinc 6 flows in between the main body 9 and the sink roll shaft 2-1, the main body of the main body is discharged through the zinc outlet 10-1. Is collected on the floor.

그리고, 본체(9)의 바닥에 누적되는 용융아연(6)의 최대누적량이 수위검출스위치(17)에 의해 검출되면 검출신호가 제어기(20)에 전송되고, 제어기에서는 압력검출센서(22)로 부터 압력치를 전송받으면서 압력조정기(24)를 제어하여 질소가스의 공급압력을 높이게 된다.Then, when the maximum accumulated amount of molten zinc 6 accumulated at the bottom of the main body 9 is detected by the water level detection switch 17, a detection signal is transmitted to the controller 20, and the controller to the pressure detection sensor 22. While receiving the pressure value from the pressure regulator 24 to control the supply pressure of the nitrogen gas to increase.

이때, 1차보호격실(10)과 본체(9)의 내압이 아연포트(1)의 용융아연(6)의 압력보다 높게 되고, 이로써 첵볼(16)이 밸브가이드관(9-1)를 따라 하강되면서 밸브시트관(28)의 하단과 이격된다.At this time, the internal pressures of the primary protective compartment 10 and the main body 9 are higher than the pressure of the molten zinc 6 of the zinc pot 1, whereby the ear ball 16 follows the valve guide tube 9-1. While descending, the valve seat tube 28 is spaced apart from the lower end.

따라서, 본체(9)의 바닥에 누적되어 있던 용융아연(6)이 밸브시트관(28)을 통해 밸브본체(15)의 용융아연에 혼입되어 재활용된다.Therefore, the molten zinc 6 accumulated at the bottom of the main body 9 is mixed with the molten zinc of the valve body 15 through the valve seat tube 28 and recycled.

또한, 본체(9)의 바닥에 누적되어 있던 용융아연(6)의 누적량이 외부로의 배출로 최소치에 도달하면 이를 수위검출스위치(17)에서 검출하여 제어기(20)에 송출하게 되고, 제어기에서는 압력검출센서(22)의 전송압력치가 일정수준에 도달할 때까지 압력조정기(24)를 통해 1차보호격실(10)과 본체(9)의 내압을 낮추게 되면 다시, 첵볼(16)이 밸브본체(15)의 용융아연의 부력에 의해 상승되면서 밸브시트관(28)을 폐쇄하게 된다.In addition, when the accumulated amount of molten zinc 6 accumulated at the bottom of the main body 9 reaches a minimum value to discharge to the outside, it is detected by the water level detection switch 17 and sent to the controller 20. When the internal pressure of the primary protective compartment 10 and the main body 9 is lowered through the pressure regulator 24 until the transmission pressure value of the pressure detection sensor 22 reaches a predetermined level, the ear ball 16 returns to the valve body. The valve seat tube 28 is closed while being lifted by the buoyancy of the molten zinc of (15).

한편, 냉각가스인입관(18)을 통해 2차보호격실(11)에 공급되는 질소냉각가스는 베어링(25)을 냉각하게 되고, 다시 냉각가스회수관(19)을 통해 회수되어 냉각기(21)에서 재냉각된 후, 냉각가스인입관을 통해 2차보호격실을 순환하게 된다.On the other hand, the nitrogen cooling gas supplied to the secondary protective compartment 11 through the cooling gas inlet pipe 18 cools the bearing 25, and is recovered through the cooling gas recovery pipe 19 again to cool the 21. After re-cooling in, the secondary protective compartment is circulated through the cooling gas inlet pipe.

본 고안은 싱크롤의 양단축을 베어링에 의해 회전 가능하도록 지지하면서 베어링의 용융아연침적을 차단함으로써 싱크롤의 수명을 연장할 수 있고, 작업의 생산성을 향상시킬 수 있는 효과를 제공한다.The present invention can extend the life of the sink roll by blocking the molten zinc deposition of the bearing while supporting both ends of the sink roll to be rotatable by the bearing, and provides an effect of improving the productivity of the work.
