일반적으로 연속주조시 생산량이 많은 낙하공법을 이용하여 물이 내부로 공급되는 롤라에 의해 쇳물이 미끄러져 이동되는데, 이때 롤라가 회전하면서 냉각수가 공급될 수 있도록 로타리조인트가 롤라단에 설치된다.In general, during continuous casting, water is slid and moved by a roller supplied with water by using a large drop production method. At this time, a rotary joint is installed at the roller end so that the cooling water can be supplied while the roller rotates.

종래 제철설비의 연속주조용 로타리조인트의 일예로서 도 4에 도시된 것과 같이, 롤라(31)의 축방향 일단에 커버(32)가 오링(32a,32b)을 매개로 안착되고, 상기 오링(32b)에 밀착되도록 부시(33)가 오링(33a)을 매개로 끼워지며, 상기 부시(33)에 메카니칼실(34a)이 일면에 열박음된 플로팅시트(34)가 오링(34b)을 매개로 끼워져 스냅링(34c)으로 축방향의 이동이 제한되도록 설치되는 한편, 상기 부시(33)의 내측으로 오링부시(35)가 오링(35a)과 레디얼부시(35b)를 매개로 설치되고, 상기 오링부시(35)의 일측으로 끼워진 스프링(36a)의 탄발력에 대향하는 위치에 오링(36b)이 가압됨과 더불어 타측으로는 상기 메카니칼실(34a)과 마주하여 밀착되는 메카니칼실(36c)이 일면에 열박음된 실링(36)이 설치되며, 상기 실링(36)은 핀(37)에 의해 상기 오링부시(35)와 같은 시기에 같은 각을 갖도록 회전되게 설치된다.As an example of a rotary casting for continuous casting of a conventional steelmaking facility, as shown in Figure 4, the cover 32 is seated on the axial end of the roller 31 via the O-ring (32a, 32b), the O-ring (32b) ), The bush 33 is inserted through the O-ring 33a so as to be in close contact with the shell, and the floating sheet 34 in which the mechanical seal 34a is snapped on one surface is inserted through the O-ring 34b. While the axial movement is limited to the snap ring 34c, the O-ring bush 35 is installed inside the bush 33 via the O-ring 35a and the radial bush 35b, and the O-ring bush ( The O-ring 36b is pressed at a position opposite to the elasticity of the spring 36a fitted to one side of the 35, and the mechanical seal 36c close to the mechanical seal 34a on the other side is shrinked on one surface. Seal 36 is installed, and the seal 36 is pinned by the pin 37 at the same time as the O-ring bush 35. It is installed to rotate to have.

또한 상기 스프링(36a)과 오링(36b)의 사이에는 압축링(38)이 설치되고, 상기 오링부시(35)에 끼워진 플랜지(39)가 보울트(39a)를 매개로 부시(33)의 이탈을 방지하도록 롤라(31)에 체결되며, 40은 냉각수가 들어간 쪽으로 빠져 나오도록 하기 위해 설치된 회수관이다. 한편 상기 실링(36)과 메카니칼실(36c)은 일체로 형성 되어 제1메카니칼실부를 형성할 수 있고, 또 상기 플로팅시트(34)와 메카니칼실(34a)는 일체로 형성되어 제2메카니칼실부를 형성할 수 있다.In addition, a compression ring 38 is installed between the spring 36a and the o-ring 36b, and the flange 39 fitted to the o-ring bush 35 prevents the detachment of the bush 33 through the bolt 39a.

본 발명의 제철설비의 연속주조용 로타리조인트는 도 1 및 도 2에 도시된 것과 같이, 롤라(100)와 결합되는 플랜지(111)와, 이 플랜지에 끼워지는 오링부시(112)와, 이 오링부시의 외주면에 끼워져 상기 롤라 및 플랜지와 함께 회전하도록 설치된 부시(113)와, 상기 오링부시의 일단부에 냉각수가 공급 및 배출되도록 설치된 엘보우(114)와, 상기 오링부시의 타단부에 상기 엘보우와 멀어지는 쪽으로 가압되도록 설치된 제1메카니칼실부(115)와, 상기 제1메카니칼실부와 밀착되도록 설치되면서 상기 롤라와 같은 시기에 같은 각을 갖도록 회전되게 설치되는 제2메카니칼실부(116)를 포함하는 제철설비의 연속주조용 로타리조인트에 있어서, 상기 오링부재(112)의 축방향으로 삽입되어 상기 제1메카니칼실부(115)를 제2메카니칼실부(116) 쪽으로 가압시키고, 상기 제1메카니칼실부와 오링부재의 끼워맞춰지는 곳으로 누수되는 것을 방지하도록 원통형 관형상의 러버부재(200)가 설치된 것을 특징으로 한다.As shown in FIGS. 1 and 2, the rotary joint for continuous casting of the steelmaking facility of the present invention includes a flange 111 coupled to the roller 100, an O-ring bush 112 fitted to the flange, and the O-ring. A bush 113 fitted to the outer circumferential surface of the bush to rotate together with the roller and the flange, an elbow 114 installed to supply and discharge cooling water to one end of the o-ring bush, and an elbow at the other end of the o-ring bush. Steelmaking equipment comprising a first mechanical seal portion 115 installed to be pressed toward the far side, and a second mechanical seal portion 116 installed to be in close contact with the first mechanical seal portion and rotated to have the same angle at the same time as the roll. The rotary joint of the present invention, the rotary ring is inserted in the axial direction of the O-ring member 112 to press the first mechanical seal portion 115 toward the second mechanical seal portion 116, the first mechanical To prevent leakage where the O-ring fitted in nikal facing seal member characterized in that the rubber member 200 of the cylindrical tubular installed.

여기서 상기 플랜지(111)와 오일부시(112)의 사이에는 상기 부시(113)로 이물질이 유입되는 것을 방지하기 위하여 더스트실(116)과 트러스트부시(117)가 끼워져 있다. 또 상기 트러스트부시(117)중의 엘보우(114)쪽에 설치된 것은 스냅링(118)으로 축방향의 이동을 제한하도록 설치되어 있다.Here, the dust chamber 116 and the thrust bush 117 are inserted between the flange 111 and the oil bush 112 to prevent foreign matter from flowing into the bush 113. Further, the elbow 114 in the thrust bush 117 is provided to limit the movement in the axial direction by the snap ring 118.

그리고 상기 러버부재(200)는 상기 오일부시(112)에 끼워져 안착된 상태로 오일부시(112)에 끼워진 제1메카니칼실부(115)인 메카니칼실을 축방향으로 가압하는 형태로 되어 있다. 이때 상기 메카니칼실과 러버부재의 내측경은 동일한 형태를 갖추어 냉각수의 유동에 방해를 주지 않도록 한다.In addition, the rubber member 200 is configured to press the mechanical seal, which is the first mechanical seal 115, fitted to the oil bush 112 in the axial direction while being fitted to the oil bush 112. At this time, the inner diameter of the mechanical seal and the rubber member have the same shape so as not to disturb the flow of the cooling water.

또한 상기 제2메카니칼실부(116)는 상기 플랜지(111)와 롤라(100)의 사이에 설치된 실링(119)에 수용되는 러버부재(200)에 의해 상기 제2메카니칼실부도 제1메카니칼실부로 가압되도록 구성되어, 상기 제1메카니칼실부(115)와 제2메카니칼실부(116)의 면접촉이 보다 확실하게 이루어지도록 한다.The second mechanical seal 116 is also pressurized by the rubber member 200 accommodated in the seal 119 provided between the flange 111 and the roller 100 to the first mechanical seal. It is configured so that the surface contact between the first mechanical seal portion 115 and the second mechanical seal portion 116 is more reliably made.

본 실시예에서는 상기 실링(119)이 플랜지(111)에 오링(120)과 스냅링(121)으로 고정된 상태를 도시하고 있다. 또 오링(122)은 롤라(100)의 측면과 실링을 위해 설치하는 것이고, 오링(123)은 롤라(100)의 내주면과 실링을 위해 설치하는 것이다.In the present embodiment, the seal 119 is shown in the flange 111 is fixed to the O-ring 120 and the snap ring 121. In addition, the O-ring 122 is to be installed for the side and the sealing of the roller 100, the O-ring 123 is to be installed for sealing with the inner peripheral surface of the roller (100).

한편 도 3에 도시된 것과 같이 상기 러버부재(200)의 단면이 Z자 형상으로 되어 일단은 오일부시(112)에 계단진홈에 밀착되고 타단은 오일부시의 내주면과 제1메카니칼실부(115)의 후면에 밀착되도록 구성된다. 이때 내외주면에 형성된 오목한 홈부(201,202)는 탄성력을 배가시키고 실링이 우수하도록 형성한 것이다.Meanwhile, as shown in FIG. 3, the cross section of the rubber member 200 has a Z shape, one end of which is in close contact with the stepped groove in the oil bush 112, and the other end of the inner peripheral surface of the oil bush and the first mechanical seal part 115. It is configured to be in close contact with the rear surface. At this time, the concave grooves 201 and 202 formed on the inner and outer circumferential surfaces are formed to double the elastic force and to provide excellent sealing.

따라서 상기 러버부재(200)의 단면이 Z자 형상으로 되어 탄발력이 우수하여 스프링의 역할을 수행할 수 있고 또 패킹의 역할도 수행하기 용이하게 된다.Therefore, the cross section of the rubber member 200 has a Z-shape and excellent elasticity can perform the role of the spring and also facilitates the role of the packing.

또 상기 러버부재는 쇼크웰경도(Hs) 30 ~ 60 정도의 것으로 제작된다. 이때 경도가 60이 넘게되면 스프링의 역할을 못하게 되고, 얼라이먼트의 역할도 못하며, 실의 접촉면에 이상마모의 현상이 발생하게 된다. 반면 30이하가 되면 스프링의 역할을 할 수 없고, 압력을 이기지 못하게 된다. 본 실시예의 단면이 Z자 형상인 러버부재(200)는 경도가 40인 상태가 가장 좋은 스프링력과 패킹력을 갖음이 실험적으로 증명되었다.In addition, the rubber member is made of a shockwell hardness (Hs) of about 30 to 60. At this time, when the hardness exceeds 60, the role of the spring, the alignment does not play, and the phenomenon of abnormal wear on the contact surface of the thread occurs. On the other hand, if it is less than 30, it cannot play the role of spring and cannot overcome the pressure. The rubber member 200 having a Z-shaped cross section of this embodiment has been experimentally proved to have the best spring force and packing force in a state of hardness 40.

상기와 같이 설명한 본 발명에 의하면, 오링부시의 내측에 메카니칼실부를 밀어줄 수 있도록 된 러버부재를 설치하여 스프링의 역할과 실링의 역할을 동시에 할 수 있으면서도 구조가 매우 간단 할 뿐만 아니라, 수명도 길어 생산성이 향상되는 효과가 있다.According to the present invention as described above, by installing a rubber member that can push the mechanical seal portion in the inner side of the O-ring bush, at the same time can play the role of the spring and the sealing, the structure is not only very simple, but also long life Productivity is improved.

또한 본 발명에 의하면, 플랜지와 롤라의 사이에 결합되는 실링에 러버부재를 설치하여 지지함으로써 제1,2메카니칼실부의 상호 밀착이 용이하게 되는 효과가 있다.In addition, according to the present invention, the rubber member is provided and supported on a seal coupled between the flange and the roller to facilitate the mutual close contact with the first and second mechanical seals.

또 본 발명에 의하면, 러버부재의 단면이 Z자 형상으로 되어 패킹과 스프링의 역할을 용이하게 되는 효과가 있다.
한편 본 발명의 바람직한 실시예에 의거 설명하였으나, 당해 기술분야의 업자라면 본 발명의 사상과 기술적수단으로 부터 벗어나지 않는 범위 내에서 본 발명을 다양하게 수정 및 변경시킬 수 있음은 물론이다. In addition, according to the present invention, the cross section of the rubber member is Z-shaped to facilitate the role of the packing and the spring.
