Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.
본 고안은 열변형 방지용 턴디쉬 커버에 관한 것으로서, 특히 턴디쉬에 용강가열장치인 프라즈마히터를 사용함에 따라 발생되는 고열과 턴디쉬내의 보온재 미투입 주조법에 따른 턴디쉬내의 용강표면에 집중되는 복사열에 의해 턴디쉬커버의 잦은 훼손을 방지하기 위한 열변형방지용 턴디쉬커버에 관한 것이다.The present invention relates to a tundish cover for preventing heat deformation, and particularly to high heat generated by using a plasma heater, a molten steel heating device, in a tundish and to radiant heat concentrated on a molten steel surface in a tundish according to a method of casting without a thermal insulation material in the tundish. It relates to a heat distortion prevention tundish cover to prevent frequent damage of the tundish cover.
일반적으로 제1도에 도시한 바와 같이 턴디쉬커버(1)는 철판(6) 내측에 평앙카(Plate Achor)(7)가 부착되고, 이 평앙카를 매체로 하여 주위에 캐스타블(Castable) 내화물(16)이 시공되어 있다.Generally, as shown in FIG. 1, the tundish cover 1 has a plate achor 7 attached to the inner side of the iron plate 6, and the castable cover is castable around the plate. The refractory 16 is constructed.
이때 턴디쉬용강(2) 위에 보온재가 투입되지 않는 신주조법의 경우 용강의 복사열과 프라즈마토오치(3)의 프라즈마고온에 의해 철판(6)이 뒤틀리고, 캐스타블 내화물(16)이 균열된다.At this time, in the case of the new casting method in which the insulating material is not put on the tundish molten steel 2, the iron plate 6 is warped by the radiant heat of the molten steel and the plasma high temperature of the plasma torch 3, and the castable refractory 16 is cracked.
또한 철판(6)의 열에 의한 변형으로 실링튜브삽입구(20)의 주위가 뒤틀리고, 이 때문에 실링튜브 및 래들스커트(5)의 취부가 불량하게 되면서 주입용강(2)의 실링이 완전치 않아 결국 턴디쉬커버(1)의 조기 교체가 불가피하게 된다.In addition, the periphery of the sealing tube insertion opening 20 is distorted due to the deformation of the iron plate 6, which causes the sealing tube and the ladle skirt 5 to be poorly mounted, and thus the sealing of the injection steel 2 is not completely completed. Early replacement of the dish cover 1 is inevitable.
본 고안은 프리즈마의 고열에 의해 철판이 뒤틀리는 것을 방지하여 캐스타블 내화물의 균열을 예방하고, 실링튜브 및 래들스커트의 실링 효과를 극대화하여 주입용강의 품질을 향상시키고, 턴디쉬커버의 수명을 연장할 수 있는 열변형방지 턴디쉬커버를 제공함에 그 목적이 있다.The present invention prevents the iron plate from twisting due to the high temperature of the prism and prevents cracking of the castable refractory, and maximizes the sealing effect of the sealing tube and ladle skirt to improve the quality of the injection steel and extend the life of the tundish cover. The purpose is to provide a thermal strain resistant tundish cover.

상기한 목적을 달성하기 위하여 본 고안은 테두리에 형상이 고정되면서 파형앙카가 부착되어 있는 다수의 형상이 캐스타블내화물에 내재되고, 원구철판의 내측면에 다수의 평앙카가 설치되며, 상기 원구철판의 외주면에 냉각수파이프 및 보호 커버가 형성되는 열변형방지 턴디쉬커버를 제공한다.In order to achieve the above object, the present invention has a plurality of shapes in which a corrugated anchor is attached while the shape is fixed to the rim is embedded in the castable refractory, and a plurality of flat anchors are installed on the inner surface of the round steel plate. It provides a heat distortion prevention tundish cover in which a coolant pipe and a protective cover are formed on an outer circumferential surface of the iron plate.
도면을 참조하여 본 고안의 구성을 설명한다.The configuration of the present invention will be described with reference to the drawings.
먼저 턴디쉬커버(1)의 전후좌우 외측면에 대형 ㄷ형상의 형강(15)이 직사각형 용접구조로 설치되어 있고, 이 형강(15)의 내측면에 원형의 파형앙카(9)가 부착되어 있으며, 이 파형앙카(9)를 매체로 하여 주변에 캐스타블 내화물(16)이 충만되어 있다.First, a large c-shaped section steel 15 is installed in a rectangular welding structure on the front, rear, left and right outer surfaces of the tundish cover 1, and a circular corrugated anchor 9 is attached to the inner surface of the tungsten cover 15. Using the corrugated anchor 9 as a medium, the castable refractory 16 is filled around.
그리고 소형 ㄷ형상의 형강(7)이 턴디쉬커버(1) 내측에 충만되어 있는 캐스타블내화물(16)의 내부에 고착되면서 상하로 걸림턱이 되어 캐스타블 내화물의 밀림을 방지하게 된다.And the small c-shaped steel (7) is fixed to the inside of the castable refractory (16) is filled inside the tundish cover (1) to be locked up and down to prevent the push of the castable refractory.
여기서 턴디쉬커버(1)의 테두리에 용접되는 대형 형강(15)의 전후외측면에 각각 다수의 고정고리가 이격되게 고정되어 있고, 이 고정고리와 턴디시 상단을 U볼트를 이용하여 밀착시킨다.Here, a plurality of fixing rings are fixed to the front and rear and outer sides of the large shaped steel 15 welded to the edge of the tundish cover 1, and the fixing rings and the top of the tundish are brought into close contact with each other using U bolts.
또한 턴디쉬커버(1)의 내측중심부 여러곳에 캐스타블 내화물(16)에 의해 고착되어 있는 소형 ㄷ형상의 형강(7)에는 전면(全面)에 파형앙카(9)가 길이 및 폭방향으로 용접되면서 캐스타블 내화물 시공시 부착이 용이하도록 되어 있고, 열전도시 신축작용이 원만하여 캐스타블 내화물과 평형앙카와의 떨어짐이 없도록 하는 특징이 있는 것이다.The corrugated anchor 9 is welded in the length and width directions to the entire surface of the small C-shaped steel 7 fixed to the inner center of the tundish cover 1 by the castable refractory 16. While the castable refractory construction is easy to attach, and the heat transfer stretching action is smooth and there is a feature that does not fall between the castable refractory and the balance anchor.
이때 리브(Rib)형태의 소형ㄷ 형강(7)은 캐스타블 내화물(16)이 충만되어 있는 턴디쉬커버(1)의 내측중심부 여러곳에 내장되어 있기 때문에 복사열에 변형이 되지 않으며, 내장된 ㄷ형강의 요철구조에 의해 캐스타블 내화물이 탈락되지 않도록 견고히 지지한다.At this time, since the rib-shaped small U-shaped steel 7 is embedded in various inner centers of the tundish cover 1 filled with the castable refractory 16, it is not deformed to radiant heat. The uneven structure of the section steel firmly supports the castable refractory.
그리고 원구철판(10)의 삽입구(18)를 통해 삽입되는 프라즈마 토오치(3)가 프라즈마 가동시 원구철판을 가열시키기 때문에 이를 냉각시키기 위해 원구철판 외주면에 냉각수파이프(8)가 조임판과 조임볼트, 너트에 의해 나선형의 달팽이 모양으로 감아 밀착되어 있다.In addition, since the plasma torch 3 inserted through the insertion hole 18 of the circular iron plate 10 heats the circular iron plate when the plasma is operated, the cooling water pipe 8 is tightened on the outer circumferential surface of the circular iron plate to tighten the tightening plate and the tightening bolt. It is wound up in a spiral snail shape by a nut and is in close contact.
여기서 냉각수파이프(8)는 입구축에 커플링이 부착되어 호스 분리가 쉽도록 하였으며, 내주면에 공급되는 냉각수가 복사열로 승열되는 원구철판(10)의 온도를 신속히 전달 냉각시켜 철피의 열변형을 방지토록 하였고, 냉각수 파이프의 외부에는 돔형상의 냉각수 파이프보호커버(13)가 설치되어 있다.Here, the cooling water pipe (8) is attached to the inlet shaft to facilitate the separation of the hose, and the cooling water supplied to the inner circumferential surface quickly transfers and cools the temperature of the spherical steel plate 10 is radiated heat radiant heat to prevent heat deformation The dome-shaped cooling water pipe protection cover 13 is installed outside the cooling water pipe.
한편 원구철판(10)의 내측면에는 대략 Y자 형상으로 형성되는 평앙카(12)가 용접고정되어 있고, 이 평앙카(12)를 매체로 하여 그 주변에 캐스타블 내화물(16)이 상, 하 분리되지 않도록 견고히 부착되도록 하고 평앙카의 수명이 반영구적으로 사용되도록 하였다.On the other hand, the inner surface of the spherical steel plate 10 is welded and fixed to the flat car 12, which is formed in a substantially Y shape, and the castable refractory 16 is formed around the flat car 12 as a medium. In addition, it was attached firmly so that it could not be separated and the life of the flat car was used semi-permanently.
이하 본 고안의 작용을 설명한다.Hereinafter will be described the operation of the present invention.
턴디쉬 커버(1)는 열변형이 작은 ㄷ형상의 형강(12)으로 요철된 굴곡부를 내면으로 하여 직사각형의 용접구조 테두리를 하고 내측에 파형앙카(9)를 횡으로 부착하고 같은 형상의 보다 적은 파형앙카를 종으로 일정간격으로 연속부착하여 캐스타블 시공시 부착이 쉽도록 하고 주조작업중 고열에 의한 팽창과 주조후 냉각 과정중 수축작용에 잘 적응하도록 부착된 캐스타블 내화물(16)이 탈락되지 않는다.The tundish cover (1) is a c-shaped steel (12) with a small thermal deformation, and has an inner surface with a bent portion to form a rectangular welded structure, and the corrugated anchor (9) is horizontally attached to the inside, and the smaller shape is used. The castable refractory (16) attached to the bellows anchor is attached to the bellows at a certain interval to make it easy to attach during castable construction, and to adapt well to expansion by high heat during casting and shrinkage during cooling after casting. It doesn't work.
그리고 원구철판(10)의 중심부에 ㄷ형상의 형강(12)을 토오치 삽입구(18)와 예열버너구멍(19), 씰링튜브삽입구(20)의 위치주변에 가로질러 용접부착하고 상하좌우 각변에 열응력이 신축작용이 잘되는 파형앙카(9)를 종횡으로 부착하고 양면공간에 캐스타블 내화물(16)로 시공하여 복사열에 의한 변형을 방지한다.The C-shaped section steel 12 is welded to the center of the spherical steel plate 10 across the position of the torch insertion hole 18, the preheat burner hole 19, and the sealing tube insertion hole 20, and is opened on the upper, lower, left and right sides. Corrugated anchor 9, which is well stretched and stressed, is attached longitudinally and horizontally, and is constructed as a castable refractory 16 in both sides to prevent deformation due to radiant heat.
또한 원구철판(10)의 내외측면에 각각 취부되는 평앙카(12)및 냉각수 파이프(8)는 고열에 의한 원구철판의 변형을 방지하여 원래 형상을 지속적으로 유지토록 하였으며, 프라즈마 토오치(3)의 삽입, 취외작업이 원할토록 한다.In addition, the flat car 12 and the coolant pipe 8 mounted on the inner and outer sides of the round iron plate 10 prevent the deformation of the round iron plate due to high heat to maintain the original shape, and the plasma torch (3). Insertion and extraction work should be desired.
본 고안은 프라즈마의 고열에 의해 철판이 뒤틀리는 것을 방지하여 캐스타블 내화물의 균열을 예방하고, 씰링튜브 및 래들스커트의 실링 효과를 극대화하여 주입용강의 품질을 향상시키고, 턴디쉬커버의 수명을 연장할 수 있는 효과를 제공한다.The present invention prevents the iron plate from twisting due to the high temperature of the plasma to prevent cracking of the castable refractory, and maximizes the sealing effect of the sealing tube and ladle skirt to improve the quality of the injection steel and extend the life of the tundish cover. It provides an effect that can be done.
