본 발명은 회전식 고주파 유도 용해로에 관한 것으로, 더욱 상세하게는 투입호퍼로 투입된 원자재가 이송스크류에 의해 이송관을 통과하여 고주파유도가열장치가 설치되고 회동가능하게 설치된 용해각관으로 자동 공급되고, 공급된 원자재는 용해각관의 내부에서 가열 용해된 후 용해각관의 유출구로 자동 배출되는 구조를 제공함에 따라, 원자재의 용해작업을 연속적이면서 보다 효과적으로 행할 수 있게 됨으로써 작업효율을 극대화시킬 수 있는 회전식 고주파 유도 용해로에 관한 것이다. The present invention relates to a rotary high frequency induction melting furnace, and more particularly, the raw materials introduced into the input hopper pass through a transfer tube by a transfer screw, and a high frequency induction heating device is installed and automatically supplied to a melt angle tube installed rotatably. As raw materials are heated and melted inside the melting tube and automatically discharged to the outlet of the melting tube, the raw materials can be continuously and more effectively dissolved. It is about.

금속코일이나 금속판재 등의 금속제품을 제조하기 위해서 원자재를 용해시킬 때에는 용해로를 사용하는데, 상기의 용해로는 가열방식에 따라 코크스·석탄가스·천연가스·중유·석탄 등을 연료로 하는 방식과 전열식으로 행하는 방식과, 아크열을 이용하는 방식과, 고주파 유도전류를 흘려서 저항발열을 이용하여 가열하는 방식이 있다. Melting furnaces are used to dissolve raw materials in order to manufacture metal products such as metal coils and sheet metals. The above-mentioned melting furnaces use coke, coal gas, natural gas, heavy oil, coal, etc. according to the heating method and heat transfer. There is a method of performing the method, a method of using arc heat, and a method of heating using resistance heat by flowing a high frequency induction current.

상기의 방식 중에서 고주파 유도전류를 흘려서 저항발열을 이용하여 가열하는 구주파 유도 가열방식은 가열효율이 우수한 반면에 쾌적한 작업환경을 제공하고 환경오염을 유발하지 않아 환경오염에 대한 관심을 높은 오늘날 가장 많이 사용되고 있다. Among the above methods, the dominant wave induction heating method, which uses high-frequency induction current and heats resistance heating, has a high heating efficiency but provides a comfortable working environment and does not cause environmental pollution. It is used.

이러한 고주파 유도 가열 방식을 적용시킨 종래의 고주파 유도 용해로는 용해물과 반응하지 않는 재료로 구성되고 지지대에 의해 경주식(傾注式) 또는 고정 식(固定式)으로 지지 설치된 본체가 환형 또는 각형으로 이루어져 있고, 상기 본체의 상부에 용해물이 되는 고체재료가 투입되는 투입구와 이를 개폐하기 위한 덮개가 설치되며, 상기 덮개의 일측으로 용해물을 배출하기 위한 출탕구가 구비되고, 상기 본체의 외주면에 고주파유도장치를 통해 고주파 유도전류가 발생하는 유도코일이 설치되어 있다. The conventional high frequency induction melting furnace using the high frequency induction heating method is composed of a material which does not react with the melt, and a main body installed in a race or fixed manner by a support is formed in a ring or a square. And an inlet through which a solid material to be a melt is introduced and a cover for opening and closing the melt, and a tap opening for discharging the melt to one side of the cover, and a high frequency on an outer circumferential surface of the body. An induction coil is installed to generate a high frequency induction current through an induction device.

따라서 투입구를 통해 적정량의 고체소재를 본체의 용량에 맞게 적정량 투입하게 되면, 상기 고체소재는 유도코일의 작용을 통해 고온으로 가열된 본체의 내부에서 용해되어 용해물이 된다. 그런 다음 본체를 일측으로 기울리게 되면 본체의 용해물은 출탕구를 통해 본체의 외부로 배출되어 여러가지 금속제품을 제조하는데 사용되는 것이다. Therefore, when the appropriate amount of the solid material is added to the capacity of the body through the inlet, the solid material is dissolved in the interior of the body heated to a high temperature through the action of the induction coil becomes a melt. Then, when the main body is inclined to one side, the melt of the main body is discharged to the outside of the main body through the tap and used to manufacture various metal products.

그러나 이러한 종래의 고주파 유도 용해로는 상기와 같이 고체소재를 본체의 용량에 맞게 적정량만 투입해야 하고, 고체소재가 용해된 용해물을 본체로부터 배출할 때는 고체소재를 투입할 수 없게 된다. 따라서 고체소재의 용해작업을 연속적으로 행할 수 없게 됨으로써 작업효율이 떨어지는 문제점이 있었다. However, such a conventional high frequency induction melting furnace is required to inject only a suitable amount of the solid material in accordance with the capacity of the main body as described above, and when discharging the melted material dissolved in the solid material from the main body it is not possible to input the solid material. Therefore, there is a problem that the work efficiency is lowered because it is not possible to continuously dissolve the solid material.

본 발명은 상기와 같은 문제점을 해결하기 위하여 발명된 것으로, 고체소재의 연속적인 용해작업을 가능하게 하여 작업효율을 극대화시킬 수 있도록 하기 위하여, 외주면에 고주파유도코일이 환설되고, 후단부에 출탕구가 형성되며, 가이드롤러에 의해 양단이 지지된 상태에서 회전모터에 의해 회전되는 체인에 의해 길이 방향과 수직으로 회전가능하게 설치된 장방형의 용해각관과; 상기 용해각관의 전단부에 연통되게 설치되어 이송모터에 의해 회동되는 이송스크류가 내설된 이송관과; 상기 이송관의 전단부에 연통되게 일체로 설치된 투입호퍼로; 구성된 회전식 고주파 유도 용해로를 제공함에 그 목적이 있다. The present invention has been invented to solve the above problems, in order to enable continuous dissolving operation of the solid material to maximize the working efficiency, the high frequency induction coil is rounded on the outer peripheral surface, the tapping hole at the rear end A rectangular melting angle tube which is formed and is rotatably installed in the longitudinal direction and vertically by a chain rotated by a rotary motor in a state where both ends are supported by the guide rollers; A transfer tube installed in communication with a front end of the dissolution angle tube and installed with a transfer screw rotated by a transfer motor; An input hopper integrally installed in communication with the front end of the transfer pipe; The purpose is to provide a rotary high frequency induction melting furnace configured.

In the rotary high frequency induction melting furnace 100 of the present invention, in dissolving a solid material of a metal using high temperature heat generated by a high frequency induction heating method, the high frequency induction coil 1 is replaced on the outer circumferential surface, A plurality of tapping holes (2) are rounded at regular intervals, and the rotation support portion (3), each of which is spoken at the front end and the rear end, is supported by the guide roller (4), and the rotation support portion (3) is spoken at the rear end. A rectangular dissolution angle tube 8 fixed to the rotary shaft 7 of the rotary motor 6 by a coupling 5 and rotatably installed; A transfer pipe 11 installed in communication with a front end of the melting tube 8 and having a transfer screw 10 installed therein and rotated by a transfer motor 9; Into the hopper 12 is integrally installed to communicate with the front end of the transfer pipe (11); Characterized in that configured.

상기 용해각관(8)은 내화벽체(13)로 둘러 쌓여진 구조이며, 상기 내화벽 체(13)에는 용해각관(8)의 출탕구(2)를 통해 배출되는 용해물의 통로가 되는 출탕로(14)가 구비되어 있다. The dissolution angle tube 8 is a structure surrounded by a fire-resistant wall 13, the tapping furnace 13 which is a passage of the melt that is discharged through the tapping hole 2 of the dissolution angle tube (8) ( 14).

상기 용해각관(8)을 다수개로 구성하고, 이를 길이방향 또는 다층으로 연설하여 고체소재의 용해시간을 연장시킬 수 있는 구조로 구성하는 것도 가능하다. It is also possible to configure a plurality of the dissolution angle tube (8), and to extend the dissolution time of the solid material by extending it in the longitudinal direction or multi-layer.

도면 중 미설명 부호 15는 용해각관(8)의 회전에 상관없이 미도시한 고주파유도장치와 고주파유도코일(1)를 상시 전기적으로 연결되게 하는 환형단자이다. In the drawings, reference numeral 15 denotes an annular terminal for electrically connecting the high frequency induction device and the high frequency induction coil 1, which are not shown, regardless of the rotation of the melting tube 8.

이와 같이 구성된 본 발명의 회전식 고주파 유도 용해로(100)는 철판이나 철근 등의 금속제품을 제조하기 위해 고체소재를 용해시킬 때에 사용하는 것으로, 고주파 유도 가열 방식으로 발생하는 고온의 열을 이용하여 고체소재를 용해하는 장치이다. The rotary high frequency induction melting furnace 100 of the present invention configured as described above is used to dissolve a solid material in order to manufacture a metal product such as an iron plate or reinforcing bar, and uses a high temperature heat generated by a high frequency induction heating method. It is a device for dissolving.

특히, 본 발명은 회전식 고주파 유도 용해로(100)는 용해코자 하는 고체소재를 연속적으로 투입하여 용해작업을 회전하면서 행할 수 있도록 함으로써, 고체소재의 용해작업의 효율성을 극대화시킨 것이 큰 특징이다. In particular, the present invention is a rotary high-frequency induction melting furnace 100 is characterized by maximizing the efficiency of the melting work of the solid material by allowing the solid material to be continuously added to rotate to dissolve the work to be dissolved.

이는 도 1에 도시된 바와 같이, 고체소재가 투입되는 투입호퍼(12), 투입호퍼(12)로 투입된 고체소재를 이송스크류(10)의 회전으로 이송시켜 공급하는 이송관(11), 이송관(11)을 통해 이송 공급되는 고체소재를 회전하면서 내부에서 서서히 용해시켜 출탕구(2)로 자동 배출하는 용해각관(8)으로 구성됨에 의해 가능하게 되는 것인데, 이의 작용을 상세하게 설명하면 다음과 같다. As shown in Figure 1, the input hopper 12, the solid material is introduced into the feed hopper 12, the conveying pipe 11 for transporting and supplying the solid material introduced into the feed hopper 12 by the rotation of the feed screw 10, the feed pipe (11) is made possible by being composed of a dissolution angle tube (8) which rotates the solid material transported and supplied through the inside slowly and automatically discharged to the tap opening (2), which will be described in detail as follows. same.

먼저, 컨베이어 등을 통해 고체소재를 투입호퍼(12)로 일정량 만큼씩 연속적으로 공급하게 되면, 상기 고체소재는 투입호퍼(12)와 연통된 이송관(11)의 전단부 로 유입됨과 동시에 이송관(11)에 내설된 이송스크류(10)가 이송모터(9)에 의해 회동되어 이송관(11)으로 유입된 고체소재가 이송관(11)의 후단부까지 자동으로 이송되면서 상기 이송관(11)과 연통된 용해각관(8)의 전단부로 공급되게 된다. First, when the solid material is continuously supplied to the input hopper 12 by a predetermined amount through a conveyor or the like, the solid material is introduced into the front end of the transfer pipe 11 in communication with the input hopper 12 and at the same time the transfer pipe The conveying screw 10 installed in the 11 is rotated by the conveying motor 9 and the solid material introduced into the conveying tube 11 is automatically conveyed to the rear end of the conveying tube 11 while the conveying tube 11 ) Is supplied to the front end of the dissolution angle tube (8) in communication with.

그리고 이송관(11)을 통해 공급된 고체소재는 고주파유도코일(1)의 작용을 통해 고온으로 가열된 용해각관(8)의 내부에서 용해되는데, 여기서 상기 용해각관(8)은 6m정도로 긴 길이를 가지므로 고체소재가 투입호퍼(12)를 통해 다른 고체소재의 연속 공급으로 인해 용해각관(8)의 후단부까지 서서히 이동하면서 완전히 용해되게 된다. And the solid material supplied through the transfer pipe 11 is dissolved in the inside of the melt angle tube 8 heated to a high temperature through the action of the high frequency induction coil (1), wherein the melt angle tube (8) is about 6m long length Since the solid material is completely dissolved while gradually moving to the rear end of the dissolution angle tube (8) due to the continuous supply of other solid material through the input hopper (12).

그런 다음 고체소재의 용해물은 용해각관(8)의 출탕구(2)로 배출된 후 내화벽체(13)에 구비된 출탕로(14)를 통해 필요한 곳으로 공급되게 된다. Then, the melt of the solid material is discharged to the tapping hole 2 of the melting angle tube 8 and then supplied to the required place through the tapping path 14 provided in the refractory wall (13).

이때 용해각관(8)은 양단부의 회동지지부(3)가 가이드롤러(4)로 지지되고 후단부의 회동지지부(3)는 커플링(5)을 매개로 회전모터(6)의 회전축(7)에 일체로 고정되어, 고주파유도코일(1)에 의해 고온으로 가열된 상태에서 회전모터(6)에 의해 회전하게 된다. At this time, the dissolution angle tube 8 is supported by the rotation support portion (3) of the both ends of the guide roller (4) and the rotation support portion (3) of the rear end to the rotary shaft (7) of the rotary motor (6) via the coupling (5). It is fixed integrally and rotated by the rotary motor 6 in a state heated to high temperature by the high frequency induction coil (1).

상기와 같이 용해각관(8)의 내부에서 서서히 이동하면서 용해되는 고체소재는 회전되는 용해각관(8)의 내면 전체와 접촉됨으로써, 고주파유도코일(1)로부터 발생하는 용해각관(8)의 고온의 열이 고체소재로 보다 효과적으로 전달되어 용해될 수 있게 되고, 뿐만 아니라 고체소재는 용해각관(8)의 회전에 의해 보다 원활하게 후단부까지 이동할 수 있게 된다. As described above, the solid material dissolved while gradually moving in the inside of the melting angle tube 8 is in contact with the entire inner surface of the rotating angle tube 8, thereby increasing the high temperature of the melting angle tube 8 generated from the high frequency induction coil 1. Heat can be more effectively transferred to the solid material to be dissolved, as well as the solid material can be smoothly moved to the rear end by the rotation of the dissolution tube 8.

그리고 용해각관(8)의 출탕구(2)는 복수로 구성되어 외주면에 일정간격으로 환설됨에 따라 용해각관(8)이 회전되더라도 고체소재의 용해물은 원활하게 외부로 배출된다. And as the tapping hole 2 of the melting angle tube 8 is composed of a plurality of turns on the outer circumferential surface at regular intervals, even if the melting angle tube 8 is rotated, the melt of the solid material is smoothly discharged to the outside.

따라서 본 발명은 고체소재를 연속적으로 공급하기만 하면 고체소재를 용해하는 작업을, 용해된 고체소재의 용해물을 배출하는 작업에 상관없이 행할 수 있게 된다. Therefore, the present invention can perform the operation of dissolving the solid material, regardless of the operation of discharging the dissolved material of the dissolved solid material only by continuously supplying the solid material.

이에 따라 구조상의 제약으로 인해 고체소재를 용해로에 투입하여 용해하는 작업과 용해로로부터 고체소재의 용해물을 외부로 배출하는 작업을 동시에 행할 수 없었던 종래의 종래의 고주파 유도 용해로의 문제점을 해결하여, 고체소재의 용해작업과 배출작업이 동시에 가능하게 됨으로써 고체소재의 용해작업을 휴지기간 없이 연속적으로 행할 수 있게 된다. This solves the problems of the conventional high frequency induction melting furnace, which was unable to simultaneously perform the operation of dissolving the solid material into the melting furnace and discharging the melt of the solid material from the melting furnace due to structural constraints. By dissolving and discharging the material at the same time, it is possible to continuously dissolve the solid material without any downtime.

그리고 본 발명은 용해각관(8)이 회전되는 구조이므로 고체소재의 용해작업을 보다 효과적으로 할 수 있게 되고, 그 용해물도 원활하게 이동할 수 있게 된다. In addition, since the present invention is a structure in which the dissolving angle tube 8 is rotated, the dissolving operation of the solid material can be more effectively performed, and the melt can be smoothly moved.

여기서 본 발명은 도 2에 도시된 바와 같이, 동일한 구조를 갖는 용해각관(8)을 두 개 이상 다층으로 연설하거나 또는 길이방향으로 길게 연설한 구조로도 구성 가능한데, 이때는 일측의 용해각관(8)의 후단부 측에 구비된 용해로(14)를 타측의 용해각관(8)의 전단부에 내설하여 연설하는 것이 바람직하다. Here, as shown in FIG. 2, the present invention can also be configured in a structure in which two or more dissolving angle tubes 8 having the same structure are addressed in two or more layers or in a longitudinal direction, in which case the dissolving angle tube 8 of one side is used. It is preferable that the melting furnace 14 provided on the rear end side of the inner side of the melting furnace 14 be installed at the front end of the melting angle tube 8 on the other side.

상기 구조는 고체소재를 용해하는 시간을 연장시켜 고체소재의 용해작업의 효율성을 보다 더 향상시킬 수 있는 구조이다. The structure is a structure that can further improve the efficiency of the solid material dissolution operation by extending the time to dissolve the solid material.

또한, 상기 구조는 공간이 협소한 작업장소에서 용해각관(8)의 길이를 짧게 형성시켜 다층으로 연설하여 협소한 작업장소에서도 설치가 가능하여 고체소재의 용해작업을 원활하게 할 수 있는 구조이다. In addition, the structure is a structure capable of smoothly dissolving the solid material can be installed in a narrow work place by forming a short length of the melt angle tube (8) in a narrow working place in a narrow space.

이에 따라 용해작업의 효율성과 작업장소의 여건에 따라 적절한 구조를 선택하여 설치하면 된다. Accordingly, the proper structure may be selected and installed according to the efficiency of melting operation and the conditions of the work place.

이와 같이 본 발명은 종래에 비하여 단위시간 동안 많은 양의 고체소재를 용해할 수 있게 되어 용해작업의 효율성 향상을 통해 철근이나 철판 등의 제조효율도 향상시킬 수 있게 된다.
