본 발명은 전기장과 자기장을 유도하여 발생되는 힘에 의해 노즐로 유입되는 유량을 제어할 수 있는 전자기장을 이용한 노즐의 유량 제어장치에 관한 것이다.The present invention relates to a flow rate control apparatus for a nozzle using an electromagnetic field that can control the flow rate flowing into the nozzle by a force generated by inducing an electric field and a magnetic field.
연속 주조시 턴디쉬에 공급된 용융금속을 주형으로 유입시키는 과정에서 용 융금속의 유입량을 조절하는 과정은 매우 중요하며, 정확한 유입량을 조절하기 위하여 많은 방법이 제시되어 왔다.In the process of introducing molten metal supplied to the tundish into the mold during continuous casting, the process of controlling the inflow of molten metal is very important, and many methods have been proposed to control the accurate inflow.
일반적으로, 용강의 유입량을 조절하는 방법으로는 스토퍼를 이용하여 유입량을 제어하는 방법이 있으며, 스토퍼를 이용하는 제어 방법은 유입되는 용강의 량을 정확히 조절할 수 있다는 장점이 있으나, 스토퍼가 턴디쉬의 내부에 잠겨 있기 때문에 시간이 경과 할수록 스토퍼가 침식되어 관리하기가 힘들다는 문제점이 발생하였다.In general, a method of controlling the inflow of molten steel includes a method of controlling inflow using a stopper, and a control method using a stopper has an advantage of precisely adjusting the amount of inflowing molten steel, but the stopper is internal to the tundish. The problem is that it is difficult to manage because the stopper is eroded over time because it is locked in.
또한, 상기와 같은 문제점을 해결하기 위하여 대한민국 특허공보 제10-1995-7172호 "용강의 주입노즐과 이를 이용한 유량제어방법"에서는 별도의 스토퍼가 형성되지 않고, 슬라이딩 게이트를 이용한 용강의 유입량을 제어하는 방법을 제시하고 있으나, 이 방법은 슬라이딩 게이트의 주변으로 열이 방출되면서 게이트의 주변이 응고하기 쉽고 미세한 변화에도 제어량이 바뀔 수 있는 문제점이 있었다.In addition, in order to solve the above problems, Korean Patent Publication No. 10-1995-7172 "Injection nozzle of molten steel and a flow control method using the same" does not have a separate stopper, and controls the inflow of molten steel using a sliding gate. However, this method has a problem in that the heat is released to the periphery of the sliding gate, so that the periphery of the gate is easily solidified and the control amount can be changed even in the minute change.
본 발명은 상술한 문제점을 해결하기 위한 것으로서, 노즐의 내부에 전기장과 자기장을 유도하여 발생되는 힘에 의하여 용융금속의 이송량을 제어하는 전자기장을 이용한 노즐의 유입량 제어장치를 제공하는 것을 본 발명의 기술적 과제로 한다.The present invention is to solve the above-mentioned problems, to provide an apparatus for controlling the flow rate of the nozzle using an electromagnetic field for controlling the transfer amount of the molten metal by the force generated by inducing an electric and magnetic field inside the nozzle It is a task.
본 발명의 전자기장을 이용한 노즐의 유입량 제어장치는 사각기둥 형상으로 형성된 노즐과 상기 노즐의 내부 벽면에 긴밀하게 부착되며, 서로 마주보게 형성되 는 한 쌍의 동판과 상기 벽면을 관통하여 강판에 전원을 공급하는 전원공급장치 및 상기 동판이 형성된 벽면과 직교하는 벽면의 외부로 일정거리 이격되게 위치하며, 서로 마주보는 한 쌍의 직류자석으로 이루어지는 것을 특징으로 한다.An apparatus for controlling the flow rate of a nozzle using an electromagnetic field of the present invention is closely attached to a nozzle formed in a square pillar shape and an inner wall surface of the nozzle, and supplies power to a steel plate through a pair of copper plates formed to face each other and the wall surface. The power supply and the copper plate is located at a predetermined distance apart from the wall surface orthogonal to the wall surface is formed, characterized in that consisting of a pair of DC magnets facing each other.
이하, 본 발명에 따른 실시예를 첨부도면을 참조하여 상세히 설명한다.Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명의 전자기장을 이용한 노즐의 유입량 제어장치의 개요도이고, 도 2는 전자기장이 형성되는 노즐의 일부분을 절단한 사시도로서, 용융금속(3)이 채워진 턴디쉬(1)와 상기 용융금속(3)을 주형틀(7)에 유입하는 노즐(5)로 이루어지며, 상기 노즐(5)은 사각기둥 형상으로 형성되는 것을 특징으로 한다.1 is a schematic view of a flow rate control device for a nozzle using an electromagnetic field of the present invention, Figure 2 is a perspective view of a portion of the nozzle is formed of the electromagnetic field, the tundish (1) filled with molten metal (3) and the molten metal (3) is made of a nozzle (5) flowing into the mold 7, the nozzle (5) is characterized in that it is formed in a square pillar shape.

또한, 상기 동판(11)이 형성된 벽면과 직교하는 벽면의 외부로는 마주보는 한 쌍의 직류자석(9)이 형성되고, 상기 직류자석(9)은 마주보는 면이 서로 다른 극(N, S)을 갖도록 위치하는 것이 바람직하다.In addition, a pair of direct-
이하, 본 발명에 따른 전자기장을 이용한 노즐의 유입량 제어장치의 작동을 첨부도면을 참조하여 상세히 설명한다.Hereinafter, the operation of the apparatus for controlling the flow rate of the nozzle using the electromagnetic field according to the present invention will be described in detail with reference to the accompanying drawings.
도 3은 전자기장이 형성되는 상태를 보인 흐름도이고, 도 4는 본 발명에 응용되는 플레밍의 왼손 법칙을 나타내는 도면이다.3 is a flowchart showing a state in which an electromagnetic field is formed, and FIG. 4 is a diagram showing a left hand rule of Fleming applied to the present invention.
먼저, 전원공급장치(13)에서 동판(11)에 전원을 공급하게 되면, 직류자석에 의해 노즐(5)의 내부로 N극에서 S극으로 자장의 방향(17)이 인가되고, 전류는 동판 (11)을 통하여 전류의 방향(15)로 흐르게 된다.First, when power is supplied to the
이때, 도 4에 도시된 바와 같이, 플레밍의 왼손법칙에 의해 용융금속이 흘러가는 반대 방향으로 힘이 발생하며, 전자기력의 강도에 따라 용융금속의 흐름을 제어할 수 있게 되는 것이다.At this time, as shown in Figure 4, by the left-hand law of Fleming the force is generated in the opposite direction through which the molten metal flows, it is possible to control the flow of the molten metal according to the strength of the electromagnetic force.
상기와 같은 구성을 갖는 본 발명의 유량 제어장치는 노즐에 통해 유입되는 용융금속의 유입량을 별도의 스토퍼나 슬라이딩 게이트를 이용하지 않고 노즐 내부로 발생하는 전자기장에 의해 비접촉 상태에서 용융금속의 유입량을 제어할 수 있는 것이다.Flow control apparatus of the present invention having the configuration as described above controls the inflow of molten metal in the non-contact state by the electromagnetic field generated in the nozzle without the use of a separate stopper or sliding gate flow rate of the molten metal flowing through the nozzle You can do it.
