Description

전기로 노벽 점검 장치{CHECKING DEVICE OF THE FURNACE WALL}Furnace furnace wall check device {CHECKING DEVICE OF THE FURNACE WALL}

본 고안은 전기로 노벽 점검장치에 관한 것으로, 상세하게는 전기로 출탕작업이 완료된 후 노벽의 파손유무를 용이하고 안전하게 관찰할 수 있도록 관찰자를 보호하여 주는 전기로 노벽 점검장치에 관한 것이다.The present invention relates to an electric furnace furnace wall inspection apparatus, and more particularly, to an electric furnace furnace wall inspection apparatus that protects the observer to easily and safely observe the presence or absence of damage to the furnace wall after the electric furnace tapping work is completed.

전기로는 몸체와 주변의 다수 보조기기로 조합된 장치로서 용탕을 용해하는 로를 관리하는데 있어 용탕을 출탕한 후에는 전기로의 천정을 열고 작업자가 로벽의 상태를 파악한다.종래, 전기로 로벽상태를 점검하는 방법은 전기로 측부에 설치된 관측계단(80)에 작업자가 올라가 간단한 방열보조기구(110)를 휴대하여 전기로 노벽침식, 용손유무를 육안관찰하는 방법이 사용되어 왔다.An electric furnace is a device that is a combination of a body and a number of auxiliary equipments. In order to manage a furnace that melts molten metal, after the molten metal is tapped, the ceiling of the electric furnace is opened and an operator grasps the state of the furnace wall. The inspection method has been used to visually observe the furnace furnace erosion, the presence or absence of damage by carrying a simple heat dissipation aid 110 to the observation stairway 80 installed on the side of the furnace.

그러나, 종래의 방법은 고온의 로벽에 접근하여 고열에 노출된 상태에서 장시간 지체하며 육안으로 관찰하기에는 어려움이 있어 정확한 노벽상태를 점검하지 못하는 상황이 발생하였다.이로인해, 로벽의 침식용손에 적시대처하지 못하여 설비안정적인 관리측면에서 조기에 설비를 휴지하여 노벽연와 교체나 수리작업을 행하게 되어 생산성을 저하시키는 문제가 있었으며 로벽점검시 고열에 노출된 작업자는 안전사고의 위험을 내포하는 문제가 있었다.However, the conventional method has a situation in which it is difficult to observe the exact furnace wall condition because it is difficult to observe the naked eye for a long time in the state of being exposed to high temperature by approaching the furnace wall of high temperature. There was a problem of reducing productivity by stopping the equipment early and performing the replacement or repair work of the furnace wall in terms of equipment stable management.In addition, the workers exposed to high temperature during the furnace wall inspection had a problem of safety accidents.

따라서, 본 고안이 이루고자 하는 기술적 과제는 상술한 문제점을 해소하여 작업자가 고열로부터 보호됨과 동시에 정확하게 로벽침식상태를 점검할 수 있는 노벽점검장치를 제공함에 있다.Therefore, the technical problem to be achieved by the present invention is to solve the above problems to provide a furnace wall inspection apparatus that can accurately check the furnace wall erosion condition while being protected from high heat.

이하, 본 고안에 따른 작용을 첨부된 예시도면을 참고로하여 상세하게 설명하면 다음과 같다.Hereinafter, described in detail with reference to the accompanying drawings illustrating the operation according to the present invention.

본 고안이 구비된 전기로 노벽 점검장치를 이용하여 노벽을 점검하는 경우 관찰자는 계단상부로 이동하여 삼면이 방열플레이트로 둘러싸인 점검장치내에서 방열창(52)을 이용하여 노벽의 파손상태를 관찰하게 된다.따라서, 고열로부터 보호되며 장시간 정확하게 노벽을 관찰할 수 있다.또한, 노벽의 다른 부분의 관찰을 요하는 경우에는 실린더(70)를 가동하여 피스톤로드를 작동시키게 되면, 실린더(70)에 일측이 연결되고 타측은 제2고정도르레(12-1)를 통해 제1가로대(21)에 결합된 실린더로우프(71)는 풀리는 형상을 유지하게 된다.이때 제3가로대(23)에 일측이 결합되며 제1도르레(11-1)를 통한 하단에는 무게추(60)가 결합된 무게추로우프(61)는 무게추의 중량에 의해 제3가로대(23)를 당겨주게 되어 제3가로대(23)가 제1메인기둥(11)을 중심으로 회동되게 된다.따라서, 제3가로대(23)의 회동에 따라 제3가로대(23)에 결합된 제1보조기둥(40-1)도 이동되게 되어 결과적으로 제1메인기둥(11)과 제1보조기둥(40-1)간에 결합된 제1방열플레이트(51)가 회동가능하게 됨으로써 방향을 변경하게 되어 노벽의 다른부분도 관찰할 수 있게 되는 것이다.When the furnace wall is inspected using the furnace furnace wall inspection device equipped with the present invention, the observer moves to the upper part of the stairs to observe the damage state of the furnace wall using the heat radiation window 52 in the inspection device surrounded by the heat radiation plate on three sides. Therefore, it is possible to observe the furnace wall accurately for a long time and protect it from high heat. In addition, when it is necessary to observe another part of the furnace wall, by operating the cylinder 70 to operate the piston rod, one side of the cylinder 70 The connected and the other side of the cylinder rope 71 coupled to the first rail 21 through the second high precision lever 12-1 is to maintain the release shape. At this time one side is coupled to the third rail 23 At the bottom through the first pulley 11-1, the weight rope 61 coupled with the weight 60 is pulled by the third rail 23 by the weight of the weight so that the third rail 23 is It is rotated about the first main pillar 11. Therefore, according to the rotation of the third side stand 23, the first auxiliary pillar 40-1 coupled to the third side stand 23 is also moved, resulting in the first main column 11 and the first auxiliary column 40. The first heat dissipation plate 51 coupled between -1) is rotatable so that the direction can be changed so that other parts of the furnace wall can be observed.

또한, 반대로 방열창(52)을 회동시킬 경우에는 실린더(70)를 가동하여 피스톤로드를 작동시킴으로써 제1가로대(21)에 결합된 실린더로우프(71)를 당겨주게 되면 제1가로대(21)가 제2메인기둥(12)을 중심으로 회동가능하게 된다.상기의 이유로, 제1가로대(21)에 회동되게 결합된 제2보조기둥(40-2)에 회동되게 결합된 제1회동대(31)도 이동되어 제1회동대(31)에 결합된 제1보조기둥(40-1)과 제1메인기둥(11)사이에 결합된 제3가로대(23)도 회동되게 된다.On the contrary, when the heat dissipation window 52 is rotated, when the cylinder rod 71 coupled to the first rail 21 is pulled by operating the cylinder 70 to operate the piston rod, the first rail 21 is moved. The second main pillar 12 is pivotable about the center. For the above reason, the first pivot 31 pivotally coupled to the second auxiliary pillar 40-2 pivotally coupled to the first rail 21 is provided. ) Is also moved so that the third side pole 23 coupled between the first auxiliary pillar (40-1) and the first main pole (11) coupled to the first pivot (31) is also rotated.

따라서, 제3가로대(23)에 결합된 제1방열플레이트(51)와 방열창(52)도 회동되며 방향을 전환하게 되어 노벽의 다른 부분을 관찰할 수 있게 되는 것이다.Therefore, the first heat dissipation plate 51 and the heat dissipation window 52 coupled to the third side stand 23 are also rotated to change directions so that other parts of the furnace wall can be observed.

본 고안의 효과로는 관찰을 요하는 로벽을 방향을 전환하면서 정확히 관찰할 수 있게 되어 적시에 로벽 침식용손에 대처하여 로벽의 수명을 연장하며 조기에 설비를 휴지하거나 노벽연와 교체를 행하여 발생되는 생산성 저하를 방지함은 물론 관찰자를 고열로부터 보호하여 안전사고를 방지하는 효과가 있다.The effect of the present invention is to be able to observe the furnace wall that needs to be observed accurately by changing the direction, to prolong the life of the furnace wall by dealing with the erosion loss in a timely manner, and to increase productivity by prematurely stopping the equipment or replacing it with the furnace wall smoke. In addition to preventing degradation, there is an effect of preventing the safety accident by protecting the observer from high temperature.
