3 : 전열선 4 : 콘크리트층3: heating wire 4: concrete layer

본 고안은 비철금속을 용해시 단열선에서 발열되는 열을 세라크울층과 암면층으로 차단시켜서 열이 외부로 유출되는 것을 방지하고 라이너의 비철금속을 빠르게 용해 시킬 수 있는 전기로의 보온 장치에 관한 것이다. 종래의 전기로의 보온장치는 단순히 라이너 주위에 열선을 노출시키고 외부 케이스와 식면으로 보온을 했었기 때문에 외부로 방출되는 열의 양이 많아 열손실이 컸으며, 연료비가 많이 소요되는 결점이 있었고, 라이너 내부의 비철 금속을 용해시키는데 필요 이상의 시간이 소요되는 폐단이 있었다.The present invention relates to an electric furnace thermal insulation device capable of preventing heat from flowing out to the outside by blocking the heat generated from the insulation line when dissolving the nonferrous metal into the cerac wool layer and the rock wool layer, and quickly dissolving the nonferrous metal of the liner. The conventional electric furnace thermostat simply exposed the heating wire around the liner and insulated the outer case and the surface, so the amount of heat released to the outside was large, resulting in a high heat loss, a high cost of fuel, and the inside of the liner. There was a closure that took more time than needed to dissolve the nonferrous metals.
또한 용탕의 온도와 전열선의 온도를 측정치 못하여 눈짐작으로 용탕의 온도를 측정하는 원시성을 벗어나지 못하고 있는 실정이다.In addition, since the temperature of the molten metal and the temperature of the heating wire cannot be measured, the primitiveness of measuring the temperature of the molten metal by eye can not be escaped.
그리고 전열선이 라이너 주위로 노출이 되어있어 라이너의 균일시에 용해된 비철금속이 유출되어 전열선에 합치되므로 열선뿐만 아니라 전기로 전체를 교환해야 하는 결점이 있었다.In addition, since the heating wire is exposed around the liner, the non-ferrous metal dissolved in the uniformity of the liner flows out and conforms to the heating wire.
이러한 종래의 결점을 해결하기 위하여 본 고안은 세라크울층과 암면층을 형성시켜 완벽한 보온을 유지시킬 수 있으며, 전열선이 발열되는 온도와 라이너 내부의 온도를 센서로 첵크하여 자동 온도 조절을 할 수가 있어 균일한 온도를 유지할 수 있으며 라이너의 균일에 대비하여 전열선을 콘크리트층에 매몰시켜서 된 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.In order to solve the above-mentioned drawbacks, the present invention can maintain the perfect insulation by forming the cerac wool layer and the rock wool layer, and can check the temperature of the heating wire and the temperature inside the liner with a sensor to perform automatic temperature control. A uniform temperature can be maintained and the heating wire is buried in the concrete layer in preparation for the uniformity of the liner, which will be described in detail with reference to the accompanying drawings.
전기로(1) 내부에 라이너(2)를 장착하고, 전열선(3)을 매몰하고 있는 콘크리트층(4)을 라이너(2)와 간격을 두어 발열부(5)를 형성하며, 콘크리트층(4)의 외주연부로는 세라크울층(6)과 암면층(7)을 형성한 다음 저면의 내화재(8) 중간부에는 세라크울층(9)을 설치하고 라이너(2)의 내부 일측과 발열부 일측에는 온도를 감지하는 센서(10)(11)를 장착하여서 된 것이다.The liner 2 is mounted inside the electric furnace 1, and the heat generating part 5 is formed at a distance from the liner 2 by the concrete layer 4 buried with the heating wire 3, and the concrete layer 4 In the outer periphery of the c), the cerak wool layer 6 and the rock wool layer 7 are formed, and then, in the middle of the refractory material 8 at the bottom, the cerak wool layer 9 is installed, and the inner side of the liner 2 and the heat generating part On one side is to be equipped with sensors 10, 11 to detect the temperature.
도면중 미설명 부호 12는 뚜껑, 13은 컨트롤 박스이다. 이와같이 된 본 고안의 작용 효과는 전기로(1) 뚜껑(12)을 열은뒤 라이너(2) 내부에 비철금속을 넣은 후 컨트롤 박스(13)의 보턴을 누르게 되면 콘크리트층(4)에 매몰되어 있는 전열선(3)이 가열됨에 따라 콘크리트층(4)도 가열이 되어 발열을 하게 되는 것이며, 발열된 열은 발열부(5)에서 라이너(2) 주위를 선회하며 라이너(2)를 가열하여 라이너(2) 내부의 비철금속을 용해 시킬 수 있는 것이다.In the figure, reference numeral 12 denotes a lid, and 13 denotes a control box. The effect of the present invention as described above is to open the lid 12 of the electric furnace (1) and then put the non-ferrous metal in the liner (2) and press the button of the control box 13 is buried in the concrete layer (4) As the heating wire 3 is heated, the concrete layer 4 is also heated to generate heat, and the generated heat turns around the liner 2 at the heat generating part 5 and heats the liner 2 to heat the liner ( 2) It can dissolve nonferrous metal inside.
또한 콘크리트층(4)의 외주연부로 세라크울층(6)과 암면층(7)으로 둘러 쌓여 보온을 하므로 외부로 방출되는 열은 극소량에 달하며, 도한 저면의 내화재(8) 중간에 세라크울층(9)이 형성되어 있어 열이 외부로 방출되지 못하고 내부의 라이너(2)로 열을 집중시킬수 있는 것이다.In addition, the outer periphery of the concrete layer (4) is surrounded by the cerakwool layer (6) and rock wool layer (7) to insulate, so the heat released to the outside reaches a very small amount, and the cerakwool layer in the middle of the fireproof material (8) (9) is formed so that heat can not be released to the outside can concentrate the heat to the inner liner (2).
그리고 라이너(2) 내부에 장착된 센서(10)가 용탕의 온도를 감지하며 발열부(5)에 당착된 센서(11)는 전열선(3)의 온도를 감지하여 콘트롤 박스(13)로 전달하며, 콘트롤 박스의 리미트 스위치에 의하여 전원을 자동적으로 개방 또는 차단을 시켜 주면서 용탕의 온도와 전열선(3)의 온도를 자동으로 조절하여 주는 것이고, 또한 전열선(3)이 콘크리트층(4)에 매몰되어 있어 라이너(2)의 균열이 발생해도 전열선(3)에는 아무런 손상을 가져오지 않는 것이다.The sensor 10 mounted inside the liner 2 detects the temperature of the molten metal, and the sensor 11 attached to the heating unit 5 senses the temperature of the heating wire 3 and transmits the temperature to the control box 13. By automatically opening or shutting off the power by the limit switch of the control box, it automatically controls the temperature of the melt and the temperature of the heating wire 3, and the heating wire 3 is buried in the concrete layer 4 Therefore, even if a crack of the liner 2 occurs, no damage is caused to the heating wire 3.
이와 같이 된 본 고안은 세라크울층과 암면층으로 둘러 쌓여 보온을 하므로 방출되는 열을 막아 이용하므로 열손실이 없고 용탕과 전열선의 온도를 감지하는 센서가 부착되어 있어 자동으로 온도를 조절하여 주므로 일정한 온도를 유지하며 용해시킬 수 있어 능률적이며, 콘크리트층에 전열선이 매몰되어 일체가 되므로 전열선의 손상을 막을 수 있고 전열선과 콘크리트층이 함께 가열이 되어 발열은 하므로 열의 양이 많아지며 적은양의 연료로 많은 양의 비철금속을 빠른 시간내에 용해 시킬수가 있어 유지비가 저렴하고 경제적인 효과를 갖는다.The present invention has a thermal insulation surrounded by the cerakwool layer and rock wool layer to prevent the heat emitted, so there is no heat loss, and a sensor that senses the temperature of the molten metal and heating wire is attached to automatically adjust the temperature It is efficient because it can melt and maintain the temperature, and the heating wire is buried in the concrete layer to prevent the damage of the heating wire, and the heating wire and the concrete layer are heated together to generate heat, so that the amount of heat increases and with a small amount of fuel It can dissolve a large amount of nonferrous metals in a short time, so it is inexpensive to maintain and economical.
