Description
본 고안은 용융아연도금조의 싱크 롤 회전장치에 관한 것으로서, 더욱 상세하게는 용융아연도금조에 담겨져 용융아연도금을 하고자 하는 강판을 안내하는 싱크 롤의 회전을 원활하게 함은 물론, 싱크 롤의 축수부에 설치되는 베어링의 마모를 예방함으로서 싱크 롤의 진동을 방지하고 그에 따른 싱크 롤이 정적인 회전을 유도할 수 있도록 한 용융아연도금조의 싱크 롤 회전장치에 관한 것이다.The present invention relates to a sink roll rotating apparatus of a hot dip galvanizing bath, and more particularly, to smoothly rotate the sink roll for guiding a steel plate to be hot dip galvanized in a hot dip galvanizing bath, as well as the bearing part of the sink roll. The present invention relates to a sink roll rotating apparatus of a hot dip galvanized bath, which prevents the wear of a bearing installed in the bearing to prevent vibration of the sink roll and thus induces static rotation of the sink roll.
제철소의 용융아연도금공정은 도 1에 나타낸 바와 같이 풀림(annealing)처리된 강판(S)을 용융아연도금조(1)의 용융아연 속으로 통과시켜 강판(S)의 양면에 아연도금을 하는 것으로, 이는 상기 강판(S)이 스나우트(3)를 통과하여 용융아연도금조(1)로 들어와 싱크 롤(10)의 안내를 받으면서 강판(S)의 양면에 용융아연도금액(2)이 코팅 된 후 에어나이프(4) 사이를 통과하여 빠져나가게 된다.The hot dip galvanizing process of the steel mill is to pass the annealed steel sheet (S) into the molten zinc of the molten zinc plating tank (1) as shown in Figure 1 to zinc-plated on both sides of the steel sheet (S) , The steel sheet (S) is passed through the snout (3) to enter the hot dip galvanizing tank (1) is guided by the sink roll 10 while the hot dip galvanizing solution (2) is coated on both sides of the steel sheet (S) After being passed through the air knife (4).
이때 상기 용융아연도금조(1)에 잠겨져 있는 싱크 롤(10)은 도 2에 나타낸 바와 같이 양측 축수부(11)에 회전축(12)이 설치되고 그 회전축(12)은 메탈 씰 형태의 베어링(13)으로 지지되어 연속 진행되는 강판(S)과의 밀착력과 그 강판의 진행방향에 따라 회전하는 구조로 되어 있다.In this case, as shown in FIG. 2, the sink roll 10 locked to the hot dip galvanizing tank 1 is provided with a rotating shaft 12 at both bearing parts 11, and the rotating shaft 12 has a metal seal-type bearing ( 13) it is a structure which rotates according to the adhering force with the steel plate S which continues and advances, and the advancing direction of the steel plate.
이와 같이 상기 강판(S)과의 밀착력과 그 강판(S)의 진행방향에 따라 회전하는 구조로 이루어진 싱크 롤(10)은 설치초기 상태는 회전축(12)과 메탈 씰 형태의 베어링(13)간에 유격(t)이 발생하지 않지만 일정기간 사용하게 되면 베어링(13)이 마모되어 도 3에 나타낸 바와 같이 베어링(13)과 회전축(12)간의 유격(t)이 발생하게 된다.As such, the sink roll 10 having a structure that rotates according to the adhesion force with the steel plate S and the advancing direction of the steel plate S is initially installed between the rotating shaft 12 and the bearing of the metal seal type. The clearance t does not occur, but when used for a certain period of time, the bearing 13 is worn and thus the clearance t between the bearing 13 and the rotating shaft 12 is generated as shown in FIG. 3.
따라서, 상기 베어링(13)과 회전축(12)간의 유격(t)이 발생한 상태에서 사용하게되면 상기 유격으로 용융아연 및 산화아연, 그리고, 드로스 등 이물질이 들어가 마모를 더욱 가속시키고 그에 따른 싱크 롤(10)의 진동이 발생함으로 싱크 (10)롤을 취외 후 새로운 베어링으로 교체해야 한다.Therefore, when it is used in a state where the clearance t between the bearing 13 and the rotating shaft 12 is generated, foreign materials such as molten zinc, zinc oxide, and dross enter the clearance to further accelerate wear and thereby sink roll. As the vibration of (10) occurs, the sink (10) roll must be removed and replaced with a new bearing.
단 상기 베어링의 교체시기는 1내지 2주일이고 이와 같은 베어링의 잦은 교체는 생산성의 저하는 물론, 원가상승의 요인이 된다.However, the replacement time of the bearing is one to two weeks, and frequent replacement of the bearing is a factor of lowering productivity and cost.
본 고안은 상기와 같은 문제점을 감안하여 이를 해소하고자 고안한 것으로서, 그 목적은 싱크 롤의 회전을 원활하게 함은 물론, 싱크 롤의 축수부에 용융아연도금액이 침투되지 못하고, 또, 싱크 롤이 정적인 회전을 할 수 있도록 싱크 롤의 양 축수부에 설치된 회전축의 외주 면에 베어링하우징이 설치되고 상기 회전축의 외주 면과 베어링하우징의 내주면 사이에는 회전보조수단을 설치하며 상기 회전보조수단의 양측으로 에어를 공급하는 에어공급수단을 설치하여 된 용융아연도금조의 싱크 롤 회전장치를 제공함에 있다.The present invention has been devised to solve the above problems, and its purpose is to facilitate the rotation of the sink roll, as well as to prevent the molten zinc plating solution from penetrating into the bearing part of the sink roll. Bearing housings are installed on the outer circumferential surfaces of the rotating shafts installed at both bearing parts of the sink roll so as to perform this static rotation, and rotation auxiliary means are installed between the outer circumferential surfaces of the rotating shaft and the inner circumferential surfaces of the bearing housings, and both sides of the rotating auxiliary means. It is to provide a sink roll rotating apparatus of the hot-dip galvanized bath provided by the air supply means for supplying air to the air.

It is preferable to combine through.
이상과 같은 구성을 갖는 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention having the configuration as described above are as follows.
용융아연도금조(1)에 잠겨진 상태에서 연속 진행되는 강판(S)과의 밀착 력과 그 강판(S)의 진행방향에 따라 싱크 롤(10)이 회전하게 되면 회전 축(12)도 같이 회전하게 되고 에어공급수단(30)의 에어공급로(31)를 통하여 에어를 공급하게 되면에어토출공(32)을 통하여 에어가 토출 되면서 기체챔버(23)에 에어가 공급된다.When the sink roll 10 is rotated according to the adhesion force with the steel sheet S continuously progressed in the state locked in the molten zinc plating tank 1 and the advancing direction of the steel sheet S, the rotation shaft 12 also rotates as well. When the air is supplied through the air supply path 31 of the air supply means 30, the air is discharged through the air discharge hole 32 and air is supplied to the gas chamber 23.
상기와 같이 기체챔버(23)에 공급되는 에어는 소정의 압을 유지하게 되고 그 압을 유지하는 에어는 회전축(12)과 덮개 판(26)의 사이 미세 공극으로 배출되면서 용융아연도금액(2)이 베어링(22)으로 침투하는 것을 방지해준다. 따라서, 종래 문제시되던 용융아연도금액(2)의 침투로 인하여 발생하던 베어링의 마모를 방지할 수 있는 것이다.As described above, the air supplied to the gas chamber 23 maintains a predetermined pressure, and the air maintaining the pressure is discharged into the fine pores between the rotating shaft 12 and the cover plate 26, and the molten zinc plating solution 2 ) Prevents penetration into the bearing 22. Therefore, it is possible to prevent the wear of the bearing caused by the penetration of the molten zinc plating solution (2), which has been a conventional problem.
단, 상기 기체챔버(23)로 공급되는 에어는 예열된 불활성가스를 사용함이 바람직하다. 그 이유는 예열되지 않은 불활성가스를 사용하지 않게 되면 용융아연도금조(1)의 용융아연도금액이 적정온도 이하로 떨어지는 문제점이 발생하고, 불활성가스를 사용하지 않게 되면 상기 용융아연도금조(1)의 용융아연도금액이 산화되는 문제점이 발생하기 때문이다.However, the air supplied to the gas chamber 23 preferably uses a preheated inert gas. The reason is that when the inert gas that is not preheated is not used, the molten zinc plating solution of the molten zinc plating tank 1 falls below an appropriate temperature, and when the inert gas is not used, the molten zinc plating tank 1 This is because a problem of oxidizing the molten zinc plating solution of s) occurs.
또한 상기 베어링(22)은 회전축(12)을 감싸며 안전하게 지지함과 동시에 에어가 소정의 압으로 충입되어 있기 때문에 정적인 회전이 이루어져 종래 문제시되던 싱크 롤의 진동을 방지함은 물론, 안전하고 원활한 회전이 이루지는 것이다.In addition, the bearing 22 surrounds the rotating shaft 12 and supports it safely, and at the same time, since the air is filled with a predetermined pressure, static rotation is performed to prevent vibration of the sink roll, which is a conventional problem, as well as safe and smooth rotation. This is done.
이상과 같은 본 고안은 싱크 롤의 양 축수부에 싱크 롤과 함께 회전하는 회전축이 설치되고 그 회전축의 외주 면에는 베어링하우징이 설치되며 상기 회전축의 외주 면과 베어링하우징의 내주면 사이에는 회전보조수단이 설치되고 상기 회전보조수단의 양측으로는 에어를 공급하는 에어공급수단이 설치되며 상기 베어링하우징의 양단에는 회전축이 관통 수용되는 덮개 판 설치함으로서, 싱크 롤의 회전을 원활하게 함은 물론, 싱크 롤의 축수부에 용융아연도금액이 침투되는 것을 예방하여 베어링을 마모를 방지함으로서 싱크 롤의 진동이 발생하지 않음은 물론, 싱크 롤이 정적인 회전을 할 수 있도록 하는 효과가 있다.The present invention as described above is provided with a rotating shaft that rotates together with the sink roll in both bearing parts of the sink roll, the bearing housing is installed on the outer peripheral surface of the rotating shaft and the rotational auxiliary means between the outer peripheral surface of the rotating shaft and the inner peripheral surface of the bearing housing Air supply means for supplying air to both sides of the rotational auxiliary means is installed, and both ends of the bearing housing are installed with a cover plate through which a rotating shaft penetrates to smoothly rotate the sink roll, as well as the sink roll. By preventing the molten zinc plating solution from penetrating into the bearing part to prevent the wear of the bearing, vibration of the sink roll does not occur, and the sink roll can have a static rotation.
