Description

강관냉각이송장치{ALLOY PIPE COOLING AND TRANSPORTING APPARATUS}Steel pipe cooling transfer device {ALLOY PIPE COOLING AND TRANSPORTING APPARATUS}

본 발명은 강관냉각이송장치에 관한 것으로서, 보다 자세히는 강관의 이송방향에 나란하게 냉각가스를 공급하여 강관의 전 영역을 균일하게 냉각할 수 있는 강관냉각이송장치에 관한 것이다. The present invention relates to a steel pipe cooling transport device, and more particularly, to a steel pipe cooling transport device capable of uniformly cooling the entire area of a steel pipe by supplying cooling gas in parallel to the transport direction of the steel pipe.

강관의 제조를 위해서는 강판을 튜브 형태로 가공하는 방법이 사용되거나, 환봉을 천공하여 형성되는 심리스 방법이 사용된다.In order to manufacture a steel pipe, a method of processing a steel sheet into a tube shape is used, or a seamless method formed by perforating a round bar is used.

강관의 제조과정에서는 강관의 내구성을 향상시키기 위해 열처리 과정이 요구된다. 열처리가 진행된 강관들은 강관냉각장치에서 냉각과정을 거치게 된다.In the manufacturing process of a steel pipe, a heat treatment process is required to improve the durability of the steel pipe. The heat-treated steel pipes are cooled in a steel pipe cooling device.

종래 강관냉각장치들은 냉각수를 이용해 강관을 냉각하는 방법과 냉각가스를 사용하는 방법이 사용된다. 그러나, 냉각수를 이용해 강관을 냉각하는 경우 냉각수가 강관의 전 영역에 고르게 도포되지 않아 냉각수가 접촉되지 않은 부분과 접촉된 부분의 내구성에 차이가 발생되는 문제가 있었다.Conventional steel pipe cooling apparatuses use a method of cooling a steel pipe using cooling water and a method of using a cooling gas. However, when cooling a steel pipe using cooling water, there is a problem in that the cooling water is not evenly applied to the entire area of the steel pipe, so that there is a difference in durability between the part that is not in contact with the cooling water and the part that is in contact with the cooling water.

이에 본 출원인은 등록특허 제10-1979019호 "강관냉각이송장치"를 출원한 바 있다. 도 1은 개시된 "강관냉각이송장치"의 강관 냉각과정을 도시한 도면이다. Accordingly, the present applicant has applied for Registration Patent No. 10-1979019 "Steel pipe cooling transfer device". 1 is a view showing a steel pipe cooling process of the disclosed "steel pipe cooling transfer device".

도시된 바와 같이 종래 강관냉각이송장치(10)는 이송롤러(13)를 통해 직선방향으로 이송되는 복수개의 강관(A)의 하부와 상부에서 냉각가스(B1)를 공급하여 강관(A)을 냉각한다. As shown, the conventional steel pipe cooling transfer device 10 supplies cooling gas B1 from the lower and upper portions of a plurality of steel pipes A that are transferred in a linear direction through a transfer roller 13 to cool the steel pipe A. do.

종래 강관냉각이송장치(10)는 강관(A)의 상부와 하부에서 수직한 방향으로 냉각가스(B1)가 공급된 후 이송롤러(13)의 양단을 향해 이동된 후 상부의 회수챔버(15)로 회수되는 경로를 따라 순환되며 강관(A)을 냉각한다. In the conventional steel pipe cooling transfer device 10, after cooling gas B1 is supplied in the vertical direction from the upper and lower portions of the steel pipe A, it is moved toward both ends of the transfer roller 13, and then the upper recovery chamber 15 It circulates along the path returned to the furnace and cools the steel pipe (A).

그런데, 도 2에 도시된 바와 같이 냉각가스(B1)가 강관(A)의 상부와 하부로 공급된 후 양측면에서 인가되는 흡입압력에 의해 냉각가스(B1)가 강관(A)의 이송방향에 수직한 방향으로 이동되기 때문에 강관(A)에 냉각가스(B1)가 닿지 않는 사각지대가 발생되는 문제가 있었다. However, as shown in FIG. 2 , after the cooling gas B1 is supplied to the upper and lower portions of the steel pipe A, the cooling gas B1 is perpendicular to the transport direction of the steel pipe A by the suction pressure applied from both sides. Since it is moved in one direction, there is a problem in that a blind spot is generated in which the cooling gas B1 does not touch the steel pipe A.

즉, 냉각가스(B1)가 복수개의 강관(A)의 양측면으로 이동되므로 냉각가스(B1)가 강관(A)의 상부와 하부(a)는 닿으나, 강관(A)의 양측면(b)은 제대로 닿지 않게된다. 이에 따라 강관냉각이송장치(10)를 통과한 강관(A)의 상하영역(a)과 양측면영역(b)의 온도를 측정한 결과 큰 온도편차가 발생되었다. 이렇게 강관(A)의 영역별 온도에 차이가 발생되는 경우 상대적으로 빨리 냉각된 상하영역은 수축되어 강관(A) 표면이 휘어지는 변형이 발생될 수 있다. That is, since the cooling gas B1 moves to both sides of the plurality of steel pipes A, the cooling gas B1 contacts the upper and lower portions a of the steel pipe A, but both side surfaces b of the steel pipe A does not reach properly. Accordingly, as a result of measuring the temperatures of the upper and lower regions (a) and both side regions (b) of the steel pipe (A) passing through the steel pipe cooling transfer device (10), a large temperature deviation occurred. In this way, when there is a difference in the temperature for each area of the steel pipe A, the upper and lower areas cooled relatively quickly are contracted, so that the surface of the steel pipe A is bent.

이러한 구성을 갖는 본 발명에 따른 강관냉각이송장치(100)를 통한 강관 냉각과정을 도 3 내지 도 7을 참조하여 설명한다. A steel pipe cooling process through the steel pipe cooling transfer device 100 according to the present invention having such a configuration will be described with reference to FIGS. 3 to 7 .

복수개의 강관(A)은 하우징(110)의 강관유입구(111)로 나란하게 유입되고, 복수개의 강관이송롤러(121)와 접촉되며 강관배출구(113)로 배출된다. The plurality of steel pipes A are introduced into the steel pipe inlet 111 of the housing 110 in parallel, come into contact with the plurality of steel pipe transfer rollers 121 , and are discharged through the steel pipe outlet 113 .

이 과정에서 도 6에 도시된 바와 같이 강관유입구(111)로 유입된 강관(A)의 상부와 하부로 입구상부가스노즐(141a)과 입구하부가스노즐(143a)로부터 냉각가스(B1)가 공급된다. 입구상부가스노즐(141a)로부터 하부방향으로 분사된 냉각가스(B1)와 입구하부가스노즐(143a)로부터 상부방향으로 분사된 냉각가스(B1)에는 흡입팬(162)의 흡입압력이 가해진다. In this process, the cooling gas B1 is supplied from the upper inlet gas nozzle 141a and the lower inlet gas nozzle 143a to the upper and lower portions of the steel pipe A introduced into the steel pipe inlet 111 as shown in FIG. do. The suction pressure of the suction fan 162 is applied to the cooling gas B1 injected in the lower direction from the upper inlet gas nozzle 141a and the cooling gas B1 injected in the upper direction from the lower inlet gas nozzle 143a.

하우징(110)의 가운데 영역에 배치된 흡입팬(162)의 회전에 의해 하우징(110)의 내부에는 흡입압력이 작용되고, 도 6과 도 7에 도시된 바와 같이 냉각가스(B1)는 하우징(110)의 중심방향을 향해 복수개의 강관(A)의 이동방향에 나란하게 이동된다. Suction pressure is applied to the inside of the housing 110 by the rotation of the suction fan 162 disposed in the central region of the housing 110, and as shown in FIGS. 6 and 7, the cooling gas B1 is supplied to the housing ( 110) is moved parallel to the moving direction of the plurality of steel pipes (A) toward the center direction.

한편, 하우징(110)의 강관배출구(113) 측에 배치된 출구상부가스노즐(151a)과 출구하부가스노즐(153a)로부터 분사된 냉각가스(B1)도 동일하게 흡입압력이 작용되어 하우징(110)의 가운데 영역으로 강관(A)의 이동방향에 나란하게 이동된다. On the other hand, the cooling gas B1 injected from the upper outlet gas nozzle 151a and the lower outlet gas nozzle 153a disposed on the steel pipe outlet 113 side of the housing 110 also has the same suction pressure, so that the housing 110 ) in the middle region and moves parallel to the moving direction of the steel pipe (A).

이렇게 하우징(110)의 입구와 출구 양측에서 냉각가스가 서로 중심방향을 향해 이동되며 이동되는 강관(A)과 접촉된다. 강관(A)이 복수개의 강관이송롤러(121)에 의해 강관유입구(111)로부터 강관배출구(113)로 이동될 때 입구가스공급부(140)와 출구가스공급부(150)로부터 각각 배출된 냉각가스(B1)들이 하우징(110)의 외측에서 내측을 향해 이동되며 강관(A)의 외부표면을 균일하게 냉각하게 된다. 즉, 함께 이동되는 복수개의 강관(A)의 표면은 물론이고 이웃하는 강관(A) 사이의 측면, 강관(A)의 내부까지도 냉각가스(B1)가 접촉하며 균일하게 냉각하게 된다. 이에 따라 종래 강관(A)의 상하만 냉각되고 양측면은 냉각되지 않던 문제를 해소할 수 있다.In this way, at both the inlet and outlet sides of the housing 110, the cooling gas is moved toward the center of each other and is in contact with the moving steel pipe (A).

On the other hand, the heat exchange cooling gas (B2), which is cooled with the steel pipe (A) and whose temperature is increased, moves to the central region of the housing (110) and then rises toward the recovery chamber (161). The heat exchange cooling gas B2 recovered to the recovery chamber 161 is mixed with the cooling gas B1 supplied from the cooling gas replenisher 170 and then moved to the inlet blower pipe 165 and the outlet blower pipe 168 . Then, the temperature is lowered by a cooling means (not shown) provided in the inlet blower pipe 165 and the outlet blower pipe 168 , and the inlet gas connection pipe is rotated by the inlet blower fan 167 and the outlet blower fan 169 . 145 and the outlet gas connection pipe 155 are supplied.

The cooling gas B1 supplied to the inlet gas connection pipe 145 is branched into the inlet upper connecting pipe 145a and the inlet lower connecting pipe 145b, and then the inlet upper gas supply chamber 141 and the inlet lower gas supply chamber, respectively. It is supplied to (143), and is injected into the steel pipe (A) through the upper inlet gas nozzle (141a) and the lower inlet gas nozzle (143a).

이러한 방식으로 냉각가스(B1)가 분사된 후 강관(A)의 이송방향에 나란하게 냉각가스(B1)가 흡입팬(162)의 흡입압력에 의해 이동되며 강관(A)의 전영역을 균일하게 냉각하게 된다. After the cooling gas (B1) is injected in this way, the cooling gas (B1) is moved by the suction pressure of the suction fan (162) in parallel to the transport direction of the steel pipe (A), uniformly covering the entire area of the steel pipe (A). will cool
