본 발명은 고온로내에서 플레이트의 처짐을 방지하는 고온로용 브러쉬 롤(BRUSH ROLL)에 관한 것이다.The present invention relates to a brush roll for a high temperature furnace (BRUSH ROLL) to prevent the plate from sagging in the high temperature furnace.
일반적으로 압연등을 한 철판, 동판 또는 알루미늄판등의 플레이트는 그 조직이 불균일하고 거칠므로 고온(섭씨 300도 이상)의 노내에서 일정한 시간을 유지시켜 조직을 미세화하여 노냉 또는 기타의 방법으로 냉각시키는 열처리를 하게 되는데, 열처리중에 상기 플레이트를 고온의 노내부에서 이동시키게 되면, 그 자체의 중량과 고온에 의한 강성의 저하로 인하여 처지게 된다.Generally, the plate such as rolled iron plate, copper plate or aluminum plate is uneven and rough in structure, so that the structure is kept in a furnace at a high temperature (over 300 degrees Celsius) to refine the structure to cool by furnace cooling or other methods. The heat treatment is performed. If the plate is moved in the furnace at a high temperature during heat treatment, the plate is sag due to its own weight and stiffness due to high temperature.
상기 플레이트가 일정량이상 처지게 되면, 그 형상변경등으로 인하여 플레이트의 품질이 저하한다. 특히, 플레이트가 쳐져서 노의 바닥에 닿게 되면 플레이트의 품질결함은 물론 조업상의 안전을 해치게 되므로, 일정한 간격으로 롤을 회전가능케 배설하여 상기 플레이트를 받쳐주게 된다.If the plate sags over a certain amount, the plate quality is degraded due to its shape change. In particular, when the plate hits the bottom of the furnace, as well as the quality defects of the plate as well as the safety of the operation, the rolls are rotatably arranged at regular intervals to support the plate.
이러한 종류의 롤로서 스틸 롤(STEEL ROLL)이 개발되었으나, 상기 스틸 롤은 그 강도로 인하여 플레이트에 긁힘 또는 자국을 내게 되어 플레이트의 품질을 저하시키는 문제점이 있으므로, 열처리 되는 플레이트의 품질을 높이는 브러쉬 롤(BRUSH ROLL)이 개발되어 있다.STEEL ROLL has been developed as this kind of roll, but since the steel roll has a problem of deteriorating the plate quality due to its scratches or marks on the plate, the brush roll to improve the quality of the heat-treated plate. (BRUSH ROLL) is developed.
종래 고온로용 브러쉬 롤(BRUSH ROLL)은 제1도에 도시한 바와 같이, 축부재(1)의 중간외주면에는 띠로 된 브러쉬(3)가 나선식으로 감겨진 구조로 되어 있다. 상기 축부재(1)의 양측에는 상기 브러쉬(3)가 이탈하지 않도록 걸림단(1a, 1a')이 형성되어 있다.As shown in FIG. 1, a brush roll for a high temperature furnace has a structure in which a banded brush 3 is wound in a spiral manner on the middle outer circumferential surface of the shaft member 1. Engaging ends 1a and 1a 'are formed on both sides of the shaft member 1 to prevent the brush 3 from being separated.
상기 브러쉬(3)는 제2도에 도시한 바와 같은 일정한 폭을 가진 스트립판(5)의 폭방향이 U형단면으로 구부려진 후, 상기 U형의 내부공간에는 와이어 코어(6)가 삽입되고, 상기 와이어코어(6)를 돌아 구부려진 일정한 길이로 된 다수의 와이어(7)가 돌출되게 상기 스트립판(5)의 길이방향을 따라 삽입된 다음, 상기 U형의 가장자리부를 압착하여 상기 와이어(7)를 고정하는 방법으로 제조된 구조로 되어 있다.After the brush 3 is bent in a U-shaped cross section in the width direction of the strip plate 5 having a constant width as shown in FIG. 2, a wire core 6 is inserted into the U-shaped inner space. The wire core 6 is inserted along the longitudinal direction of the strip plate 5 such that a plurality of wires 7 having a constant length bent are protruded, and then the edge portion of the U-shaped is pressed to the wire ( 7) It is a structure manufactured by the method of fixing.

In addition, the middle portion 11a has a polygonal cross-sectional shape such that the brush disk 15 does not rotate in the circumferential direction of the shaft member 11, and both sides of the middle portion 11a have the fixing ring ( The circumferential strip grooves 11c and 11c 'are formed so that 19 and 19' may be fitted, and the flow path hole which is not shown in the shaft member 11 is formed so that water may flow for cooling.
상기 브러쉬 디스크(15)는 스틸재로 된 베이스 디스크(21)의 가장자리를 따라 와이어(23)가 상기 베이스 디스크(21)의 반경방향으로 돌출되게 배설된 구조로 되어 있다.The brush disk 15 has a structure in which wires 23 are arranged to protrude radially of the base disk 21 along the edge of the base disk 21 made of steel.
상기 베이스 디스크(21)는 그 두께가 0.5㎜ 내지 1.5㎜로 되어 있고, 그 가장자리에는 다수의 관통구멍(21a)이 원주방향으로 따라 인접되게 형성되어 있고, 그 중심부에는 상기 축부재(11)에 외삽되어 회전하지 않도록 다각형의 구멍이 형성되어 있다.The base disk 21 has a thickness of 0.5 mm to 1.5 mm, and a plurality of through holes 21a are formed adjacent to each other in the circumferential direction at the edge thereof, and the shaft member 11 is formed at the center thereof. Polygonal holes are formed to prevent extrapolation and rotation.
그리고 상기 관통구멍(21a)에는 다수개의 상기 와이어(23)가 그 단부가 외측으로 향하게 U형으로 삽입되어 이탈방지끈(25)에 의해 묶여져 있다.In the through hole 21a, a plurality of the wires 23 are inserted in a U-shape with their ends facing outwards and are tied by the separation preventing strap 25.
상기 와이어(23)는 그 재질이 스테인레스 강으로서, 그 직경이 0.3㎜ 내지 1.0㎜로 되어 있다.The wire 23 is made of stainless steel and has a diameter of 0.3 mm to 1.0 mm.
상기 밀착 디스크(17, 17')는 일정한 강도를 가진 금속재로 되어 있고, 상기 축부재(11)의 중간부(11a)에 외삽되도록 그 중간에 관통구멍이 형성된 디스크형상으로 되어 있다.The contact disks 17 and 17 'are made of a metal material having a certain strength, and have a disk shape in which a through hole is formed in the middle so as to be extrapolated to the middle portion 11a of the shaft member 11.
이와 같이 구성된 본 발명의 일실시예에 의한 고온로용 브러쉬 롤은 열처리를 하는 고온의 노내부에 회전가능케 배설되어 열처리하고자 하는 플레이트를 받쳐주어 플레이트의 처짐을 방지함과 동시에 이송하게 된다.The brush roll for a high-temperature furnace according to an embodiment of the present invention configured as described above is rotatably disposed in a high-temperature furnace to heat-treat to support a plate to be heat-treated, thereby preventing sagging of the plate and simultaneously transferring it.
이때, 상기 브러쉬 디스크(15)의 와이어(23)는 그 직경이 작아서 유연하게 구부려지므로 이송되는 강판의 표면에 흠집 또는 자국을 내지 않는다.At this time, the wire 23 of the brush disk 15 is small in diameter and is flexibly flexed so that it does not scratch or mark the surface of the conveyed steel sheet.
그리고, 상기 축부재(11)에는 디스크형으로 된 다수의 브러쉬 디스크(15)가 축방향으로 적층되게 배설되어 있으므로, 브러쉬 롤이 회전하더라도 종래의 브러쉬 롤과 같은 플레이트의 쏠림현상이 생기지 않는다.In addition, since the plurality of brush disks 15 having a disk shape are disposed to be stacked in the axial direction, the shaft member 11 does not cause tilting of a plate like a conventional brush roll even when the brush roll is rotated.
따라서, 열처리되는 플레이트가 안정하게 지지되며, 종래예에서와 같은 플레이트의 원위치 작업을 수행하지 않아도 되므로, 운전위험이 감소하고 플레이트의 생산성이 상승하게 된다.Therefore, the plate to be heat treated is stably supported, and since it is not necessary to perform the in-situ operation of the plate as in the conventional example, the operation risk is reduced and the productivity of the plate is increased.
앞에서 설명한 바와 같이, 본 발명에 의한 고온로용 브러쉬 롤은 축부재의 외주면에 일정한 강도를 가진 브러쉬 디스크 축방향으로 적층배설함에 의해, 열처리되는 플레이트를 안정하게 지지하여 작업안전도를 높이고 플레이트의 생산성을 높인다는 매우 뛰어난 효과가 있다.As described above, the brush roll for the high temperature furnace according to the present invention is laminated on the outer circumferential surface of the shaft member in the axial direction of the brush disk, thereby stably supporting the plate to be heat-treated to increase work safety and improve the productivity of the plate. Increasing has a very good effect.
