Description
본 고안은 스케일제거용 노즐에 관한 것으로, 특히 스프레이파이프에 스프레이가이더를 연결시켜 분사되는 고압수에 회전력을 줌으로써 빌렛트의 표면에 형성된 스케일을 제거하는데 최대 효과를 줄 수 있는 스케일제거용 노즐에 관한 것이다.The present invention relates to a descaling nozzle, and more particularly, to a descaling nozzle that can give a maximum effect to remove the scale formed on the surface of the billet by giving a rotational force to the high-pressure water sprayed by connecting the spray guider to the spray pipe will be.
일반적으로, 선재공정은 강편 및 연주공정에서 생산된 빌렛트를 가열, 압연, 냉각, 정정(검사 및 시험)공정을 거쳐 그 직경이 5.5~42mm에 이르는 와이어로드(Wire rod)로 생산하게 되고, 그 용도에 있어 바늘로부터 로켓부품에 이르기까지 매우 다양하며, 특히 자동차용 쇽압소바(Shock Absobar)에 사용되는 선재제품은 매우 미려한 표면을 요구하게 된다.In general, the wire rod process is produced by the wire rod of the diameter of 5.5 ~ 42mm through the heating, rolling, cooling, correction (inspection and test) process of the billet produced in the steel sheet and casting process, Their applications range from needles to rocket parts and, in particular, wire rods used in automotive shock absorbers require very beautiful surfaces.
한편, 선재의 소재인 빌렛트(Billet)에서 압연되어 나온 제품에는 그 표면에 여러형태의 흠이 발생되는데, 특히 스캡(Scap)의 경우 제품표면에 딱지처럼 발생되는 흠으로서, 가열된 빌렛트의 표면에 철의 산화물인 스케일에 의하여 생성된다.On the other hand, the products rolled out from the billet (Billet), a material of the wire rod, have various types of flaws on the surface thereof. Especially, in the case of Scap, the flaw is generated as a scab on the surface of the product. It is produced by the scale, which is an oxide of iron on the surface.
그리고, 추출된 빌렛트의 표면에 형성되는 스케일이 제거되지 않은 상태에서 압연될 때에는 소재와 스케일이 압착되어 최종제품에 그대로 남아있게 되어 후공정에서 신선작업시 소재가 절단되는 등의 불량품이 발생된다.In addition, when the scale formed on the surface of the extracted billet is rolled without being removed, the material and scale are compressed and remain in the final product, resulting in defective products such as cutting of the material during the fresh work in a later process. .
따라서, 종래에는 가열로의 추출설비에 디스케일러장치를 설치하여 가열로에서 추출되는 빌렛트의 표면에 200bar의 고압수를 분사하여 스케일을 제거하는 작업을 실시하였다.Therefore, in the related art, a descaler was installed in an extraction facility of a heating furnace, and 200 bar high-pressure water was sprayed onto the surface of the billet extracted from the heating furnace to remove scale.
그러나, 제1도에 도시한 바와같이 디스케일러장치의 디스케일러노즐(1)은 고압수가 스프레이파이프(10)에서 노즐가이드(11)를 통하여 빌렛트의 표면에 단순히 일직선으로 분사되어 벨렛트의 표면에 부착되어 있는 스케일을 완전히 제거할 수 없을 뿐만 아니라 오히려 가열상태인 빌렛트의 표면온도를 냉각시켜 압연작업이 불가능하게 된다.However, as shown in FIG. 1, the descaler nozzle 1 of the descaler device is simply sprayed with a high pressure water on the surface of the billet through the nozzle guide 11 in the spray pipe 10 so that the surface of the belt Not only does the scale attached to the filter not be completely removed, but also the rolling operation is impossible by cooling the surface temperature of the heated billet.
본 고안은 스프레이파이프에 스프레이가이더를 연결시켜 분사되는 고압수에 회전력을 줌으로써 빌렛트의 표면에 형성된 스케일을 완벽하게 제거할 수 있는 스케일제거용 노즐을 제공함에 그 목적이 있다.The object of the present invention is to provide a descaling nozzle that can completely remove the scale formed on the surface of the billet by applying a rotational force to the spray pipe connected to the spray guider to the spray pipe.

상기한 목적을 달성하기 위하여 본 고안은 고압수공급배관과 연결되는 스프레이파이프로부터 고압수를 공급받아 빌렛트의 표면에 분사함으로써 빌렛트의 표면에 형성된 스케일을 제거하는 스케일제거용 노즐에 있어서, 그 대경부가 상기 스프레이파이프의 수나사부와 나사결합되고, 그 소경부를 통해 고압수를 분사하도록 설치되는 고정어댑터와; 방사상의 블레이드가 나선형으로 비틀어지도록 형성되고, 상기 블레이드의 고정턱이 상기 지지력에 밀착 지지되도록 상기 고정어댑터에 내장되는 스프레이가이더로 구성되는 것을 스케일제거용 노즐을 제공한다.In order to achieve the above object, the present invention provides a descaling nozzle for removing the scale formed on the surface of the billet by receiving the high pressure water from the spray pipe connected to the high pressure water supply pipe and spraying the surface of the billet, A fixed adapter having a large diameter screwed to the male screw portion of the spray pipe and installed to spray high pressure water through the small diameter portion; The radial blade is formed to be twisted in a spiral, it is provided with a nozzle for removing the scale consists of a spray guider embedded in the fixed adapter such that the fixing jaw of the blade is closely supported by the supporting force.
도면을 참조하여 본 고안의 구성을 설명한다.The configuration of the present invention will be described with reference to the drawings.

고압수공급배관(도시안됨)과 연결되는 스프레이파이프(10)의 선단부에는 수나사부(10-1)가 형성되어 있고, 이 스프레이파이프의 수나사부에는 고정어댑터(31)의 대경부(14)가 나사결합되어 있다.A male screw portion 10-1 is formed at the tip of the spray pipe 10 connected to the high-pressure water supply pipe (not shown), and the large diameter portion 14 of the fixed adapter 31 is formed at the male screw portion of the spray pipe. Screwed in.
이때, 그 외주면 일측이 육각형상을 이루어 고정어댑터(31)에는 그 내주면에 암나사를 형성하는 대경부(14)와 소경부(16)가 연이어 형성되어 있고, 이 대경부(14)와 소경부(16)의 경계에 지지턱(12)이 형성되어 있다.At this time, one side of the outer circumferential surface is formed in a hexagonal shape, and the fixed adapter 31 has a large diameter portion 14 and a small diameter portion 16 successively formed on the inner circumferential surface thereof, and the large diameter portion 14 and the small diameter portion ( The support jaw 12 is formed in the boundary of 16).
그리고, 고정어댑터(31)에 내장되는 스프레이가이더(25)는 방사상으로 형성되는 6개의 블레이드(15)가 나선형으로 비틀어지도록 형성되어 있다.The spray guider 25 embedded in the fixed adapter 31 is formed such that six blades 15 radially twisted in a spiral manner.
다시말하면, 스프레이가이더(25)의 블레이드(15)를 한 방향으로 90°이상 비틀리도록 형성하는 이유는 블레이드의 축방향길이와 관계없이 고정어댑터(31)의 소경부(16)로부터 분사되는 고압수에 충분한 회전력을 주기 위함이다.In other words, the reason why the blade 15 of the spray guider 25 is formed to be twisted by 90 ° or more in one direction is that the high pressure water sprayed from the small diameter part 16 of the fixed adapter 31 irrespective of the axial length of the blade. This is to give enough torque to
여기서, 스프레이가이더(25)의 블레이드(15)에는 그 외측면 전방측에 고정턱(13)이 형성되어 있고, 이 고정턱은 고정어댑터(31)에 내장시 지지턱(12)에 밀착되도록 설치된다.Here, the fixing guide 13 is formed in the blade 15 of the spray guider 25 on the front side of the spray guide 25, and the fixing jaw is installed to be in close contact with the supporting jaw 12 when built in the fixing adapter 31. do.
한편, 스프레이가이더(25)를 고정어댑터(31)에 내장한 상태에서 대경부(14)를 스프레이파이프(10)의 수나사부(10-1)에 나사결합시키면 스프레이가이더(25)의 전단면이 수나사부(10-1)의 선단면에 밀착되는 동시에 고정턱(13)이 지지턱(12)에 밀착되면서 고정 설치된다.On the other hand, when the large diameter portion 14 is screwed into the male screw portion 10-1 of the spray pipe 10 while the spray guider 25 is embedded in the fixed adapter 31, the front end surface of the spray guider 25 The fixing jaw 13 is closely attached to the supporting jaw 12 while being fixed to the front end face of the male screw portion 10-1.
이하, 본 고안의 작용을 설명한다.Hereinafter, the operation of the present invention.
디스케일러펌프의 펌핑작동으로 공급배관(도시안됨)을 통해 공급되는 고압수는 스프레이파이프(10)로부터 배출되는 순간 스프레이가이더(25)의 블레이드(15)에 의해 6개로 분할되어 고정어댑터(31)에 유입된다.The high-pressure water supplied through the supply pipe (not shown) by the pumping operation of the descaler pump is divided into six by the blade 15 of the spray guider 25 at the moment of being discharged from the spray pipe 10 and fixed adapter 31. Flows into.
이때, 고정어댑터(31)를 통과하는 고압수는 블레이드(15) 사이에 형성되는 곡선의 유로를 따라 흐르면서 회전력을 갖게 되고, 직진력과 회전력을 동시에 가진 상태로 고정어댑터(31)의 소경부(16)로부터 배출된다.At this time, the high-pressure water passing through the fixed adapter 31 has a rotational force flowing along the flow path of the curve formed between the blades 15, the small diameter portion of the fixed adapter 31 in the state having both a straight and a rotational force ( 16).
여기서, 고정어댑터(31)의 소경부(16)로부터 배출되는 고압수는 빌렛트의 표면에 회전상태로 부딪히면서 스케일을 효과적으로 완벽하게 제거하게 된다.Here, the high-pressure water discharged from the small diameter portion 16 of the fixed adapter 31 effectively hits the surface of the billet in a rotational state to effectively remove the scale.
본 고안은 스프레이파이프에 스프레이가이더를 연결시켜 분사되는 고압수에 회전력을 줌으로써 빌렛트의 표면에 형성된 스케일을 완벽하게 제거할 수 있고, 이로부터 작업의 생산성향상을 구현할 수 있는 효과를 제공하게 된다.The present invention connects the spray guider to the spray pipe and gives a rotational force to the high-pressure water to be sprayed to completely remove the scale formed on the surface of the billet, thereby providing the effect of improving the productivity of the work.
