일반적으로 도1에 도시한 바와같이 턴디쉬(22)내의 용강(28-1)은 침지노즐(25)을 통해 몰드(19)로 배출되는데, 이때 튜브(27)내의 용강(28-2)과 공기의 접촉을 방지하기 위하여 용강(28-2)의 상면에는 몰드플럭스(26)가 투입된다.In general, as shown in FIG. 1, the molten steel 28-1 in the tundish 22 is discharged to the mold 19 through the immersion nozzle 25, wherein the molten steel 28-2 in the tube 27 and the molten steel 28-2 are discharged. In order to prevent contact of air, a mold flux 26 is injected into the upper surface of the molten steel 28-2.

그러나 몰드플럭스(26)는 몰드튜브(27)의 내측면과 풋롤(21)의 외주면에 스케일 및 이물질 등과 함께 융착되어 주편의 품질을 저하시키고, 몰드튜브(27)의 내측면과 풋롤(21)의 외주면에 마모를 발생시킨다.However, the mold flux 26 is fused to the inner surface of the mold tube 27 and the outer circumferential surface of the foot roll 21 together with scales and foreign matters, thereby degrading the quality of the cast steel, and the inner surface of the mold tube 27 and the foot roll 21. Wear occurs on the outer circumferential surface of the

한편 이러한 몰드튜브(27)의 내측면과 풋롤(21)의 외주면에 융착된 몰드플럭스(26), 스케일 및 이물질 등을 제거하기 위하여 종래에는 고압의 냉각수를 분사하였으나, 그 분사압이 충분하지 못하여 만족할만한 효과를 얻을 수 없었다.Meanwhile, in order to remove the mold flux 26, the scale, and the foreign matter fused to the inner surface of the mold tube 27 and the outer circumferential surface of the foot roll 21, a high pressure cooling water was conventionally injected, but the injection pressure was not sufficient. A satisfactory effect could not be obtained.

또한 몰드튜브(27)의 내측면과 풋롤(21)의 외주면에 분사된 냉각수는 주위로 비산되어 전기 또는 계장 설비에 트러블을 발생시키고, 주조작업중 에러발생의 원인을 제공하게 된다.In addition, the cooling water sprayed on the inner surface of the mold tube 27 and the outer peripheral surface of the foot roll 21 is scattered to the surroundings, causing trouble in the electrical or instrumentation equipment, and provides a cause of error during the casting operation.

본 고안은 몰드의 상부를 커버로 덮은 상태에서 몰드튜브내를 상하이동하는 공급라인의 노즐을 통해 고압의 냉각수를 분사시켜 몰드튜브의 내주면과 풋롤의 외주면에 부착되어 있는 몰드플럭스, 이물질, 스케일 등을 제거하는 몰드튜브(Mold Tube) 및 풋롤(Foot) 세척장치를 제공함에 그 목적이 있다.The present invention is a mold flux, foreign matter, scale, etc. attached to the inner circumferential surface of the mold tube and the outer circumferential surface of the foot roll by spraying a high-pressure cooling water through the nozzle of the supply line moving up and down the mold tube while covering the upper part of the mold with a cover The purpose is to provide a mold tube (foot mold) and foot roll (Foot) cleaning device for removing the.

대략 ㄱ자형의 메인공급관(5)은 선단에 암커플링(6-1)이 결합되어 있고, 이 암커플링(6-1)에 냉각수호스(7)의 수커플링(6-2)이 결합된다.The approximately A-shaped main supply pipe (5) has a female coupling (6-1) coupled to the tip, and the female coupling (6-1) has a male coupling (6-2) of the cooling water hose (7). Combined.

또한 메인공급관(5)은 상단부에 메인밸브(5-1)가 설치되어 있고, 중단부에 원통의 실린더관(12)이 상하이동이 가능하도록 외장되어 있으며, 이 실린더관(12)의 하단면에는 사각판의 커버(14)가 부착되어 있다.In addition, the main supply pipe (5) is provided with a main valve (5-1) at the upper end, and the cylinder tube (12) of the cylinder in the middle of the interruption is external to enable the shandong, and the lower surface of the cylinder tube (12) The cover 14 of the square plate is attached.

이때 실린더관(12)에 내장되는 메인공급관(5)에는 스토퍼판(11)의 외주면이 실린더관의 내주면에 밀착되도록 스토퍼판이 외장되어 있고, 하강되는 스토퍼판(11)에 의해 압축되도록 스프링(13)이 결합되어 있다.At this time, the main supply pipe (5) embedded in the cylinder tube 12 has a stopper plate is provided so that the outer circumferential surface of the stopper plate 11 is in close contact with the inner circumferential surface of the cylinder tube, the spring 13 so as to be compressed by the stopper plate 11 is lowered ) Is combined.

여기서 실린더관(12)의 상부에 위치하는 메인공급관(5)의 외주면에 감져지는 공급라인(9)은 상단이 수평되게 메인공급관(5)의 상단부에 내장되면서 냉각수호스(7)로 부터 공급되는 냉각수를 흡수하게 된다.Here, the supply line 9 wound around the outer circumferential surface of the main supply pipe 5 positioned above the cylinder pipe 12 is embedded in the upper end of the main supply pipe 5 so that the upper end is horizontally supplied from the cooling water hose 7. Absorbs the cooling water.

또한 공급라인(9)의 하단은 실린더관(12)의 상면에 니플(9-2)에 의해 관통 결합되어 있고, 이로써 공급라인(9)에 공급되는 세척수는 실린더관내로 유입되어 스토퍼판(11)을 하부로 밀게 되고, 동시에 메인공급관(5)도 하강하게 된다.In addition, the lower end of the supply line 9 is coupled to the upper surface of the cylinder tube 12 by a nipple 9-2, whereby the washing water supplied to the supply line 9 flows into the cylinder tube and stopper plate 11 ) Is pushed downward, and at the same time the main supply pipe (5) is also lowered.

그리고 밸브(8-1)에 의해 개폐되는 드레인라인(8)은 상단이 메인공급관(5)의 상부에 연결되어 있고, 하단이 실린더관(12)의 상면에 니플(8-2)에 의해 관통 결합되어 있다.The upper and lower ends of the drain line 8 opened and closed by the valve 8-1 are connected to the upper part of the main supply pipe 5, and the lower end penetrates the upper surface of the cylinder pipe 12 by the nipple 8-2. Are combined.

따라서 공급라인(9)을 통해 더 이상 세척수가 공급되지 않을 경우 압축되었던 스프링(13)의 압축탄성력에 의해 스토퍼판(11)이 상향이동되면서 실린더관(12)내의 냉각수가 개방되어 있는 드레인라인(8)을 통해 공급라인(9)으로 배출된다.Therefore, when the wash water is no longer supplied through the supply line 9, the stopper plate 11 is moved upward by the compressive elastic force of the spring 13 that has been compressed, and the drain line in which the coolant in the cylinder tube 12 is opened ( 8) is discharged to the supply line (9).

한편 몰드튜브(27)내로 장입되는 메인공급관(5)의 하단부 외주면에는 몰드튜브의 내주면에 밀착되는 가이드관(15)이 부착되어 있고, 특히 공급라인의 하단에는 회전커플링(4)에 의해 스크루블레이드관(20)이 결합되어 있다.On the other hand, a guide tube 15 closely attached to the inner circumferential surface of the mold tube is attached to the outer circumferential surface of the lower end portion of the main supply pipe 5 inserted into the mold tube 27, and in particular, the lower end of the supply line is screwed by a rotary coupling 4. Blade tube 20 is coupled.

그리고 스크루블레이드(Screw Blade)가 내장되는 스크루블레이드관(20)은 외주면 하단에 대략 ￢자형의 노즐(16)이 동서남북 4방향으로 결합되어 있다.And the screw blade (Screw Blade) is built in the screw blade tube 20 has a substantially U-shaped nozzle 16 is coupled to the four directions east, south, north and the bottom of the outer peripheral surface.

따라서 메인공급관(5)을 통해 고압의 세척수가 공급되면 스크루블레이드관(20)은 세척수의 통과로 회전하게 되고, 회전 상태에서 세척수가 분사되는 노즐(16)은 작용과 반작용의 운동법칙에 의해 더욱 빠른 속도로 스크루블레이드관을 회전시키게 된다.Therefore, when the high-pressure washing water is supplied through the main supply pipe 5, the screw blade blade 20 is rotated by the passage of the washing water, and the nozzle 16, in which the washing water is sprayed in the rotating state, is further acted on by the laws of motion and reaction. The screw blades rotate at a high speed.

이하 본 고안의 작용을 설명한다.Hereinafter will be described the operation of the present invention.

먼저 커버(14)를 몰드(19)의 상부에 안착시킨 후, 커플링(6-1,6-2) 결합을 이용하여 메인공급관(5)에 냉각수호스(7)를 결합시키고, 메인밸브(5-1)를 개방하면 메인공급관내로 세척수가 공급된다.First, the cover 14 is seated on the upper portion of the mold 19, and then the cooling water hose 7 is coupled to the main supply pipe 5 by using couplings 6-1 and 6-2. When 5-1) is opened, the washing water is supplied into the main supply pipe.

이때 밸브(9-1)를 개방하는 동시에 밸브(8-1)를 닫으면 공급라인(9)을 통해 세척수가 실린더관(12)에 유입되어 스토퍼판(11)을 아래로 밀게되고, 동시에 메인공급관(5)이 스프링(13)의 탄성력을 이기고 하강하기 시작한다.At this time, when the valve 9-1 is opened and the valve 8-1 is closed, the washing water flows into the cylinder tube 12 through the supply line 9 to push the stopper plate 11 downward, and at the same time, the main supply tube. (5) overcomes the elastic force of the spring 13 and begins to descend.

여기서 몰드튜브(27)의 내주면 상단부에 위치하던 노즐(16)은 메인공급관(5)에 의해 하강되는 동시에 스크루블레이드관(20)에 의해 회전되면서 몰드튜브의 내주면과 풋롤(21)에 부착되어 있는 이물질을 향해 세척수를 분사하게 된다.Here, the nozzle 16 located at the upper end of the inner circumferential surface of the mold tube 27 is lowered by the main supply pipe 5 and rotated by the screw blade tube 20 and attached to the inner circumferential surface of the mold tube and the foot roll 21. The washing water is sprayed toward the foreign matter.

한편 몰드튜브(27)와 풋롤(21)의 세척작업이 완료되면 먼저 메인밸브(5-1)와 밸브(9-1)를 차례로 닫은 후, 밸브(8-1)를 개방하면 실린더관(12)내의 세척수가 드레인라인(8)을 통해 메인공급관(5)으로 배출된다.On the other hand, when the cleaning operation of the mold tube 27 and the foot roll 21 is completed, the main valve 5-1 and the valve 9-1 are sequentially closed, and then the valve 8-1 is opened to open the cylinder tube 12. The washing water in) is discharged to the main supply pipe (5) through the drain line (8).

또한 압축상태의 스프링(13)이 원상태로 복귀되면서 스토퍼판(11)을 위로 밀어 올리게 되고, 상향이동되는 메인공급관(5)을 따라 노즐(16)로 상승되어 원상태로 복귀된다.In addition, as the spring 13 in the compressed state is returned to its original state, the stopper plate 11 is pushed upward, and is lifted up to the nozzle 16 along the main supply pipe 5 which is moved upward to return to the original state.

이때 스크루블레이드관(20)은 메인공급관(5)으로부터 잔류 냉각수가 공급되어 상승중에도 계속 회전하게 되고, 이로써 노즐(16)은 몰드튜브(27)의 내주면에 지속적으로 냉각수를 분사하게 된다.At this time, the screw blade blade 20 is supplied to the remaining cooling water from the main supply pipe 5 to continue to rotate during the rise, thereby the nozzle 16 is to continuously spray the cooling water to the inner peripheral surface of the mold tube (27).

본 고안은 몰드의 상부를 커버로 덮은 상태에서 몰드튜브내를 상하이동하는 공급라인의 노즐을 통해 고압의 냉각수를 분사시켜 몰드튜브의 내주면과 풋롤의 외주면에 부착되어 있는 몰드플럭스, 이물질, 스케일 등을 제거함으로써 작업의 생산성 및 주편의 표면 품질을 향상시킬 수 있고, 설비트러블을 방지할 수 있는 효과를 제공한다.The present invention is a mold flux, foreign matter, scale, etc. attached to the inner circumferential surface of the mold tube and the outer circumferential surface of the foot roll by spraying a high-pressure cooling water through the nozzle of the supply line moving up and down the mold tube while covering the upper part of the mold with a cover By eliminating this, the productivity of the work and the surface quality of the cast can be improved, and the effect of preventing equipment troubles can be provided.
