Description

칸탈을 이용한 유리 제조용 전기용해로 및 이 전기용해로를 이용한 유리제조방법{ELECTRIC FURNACE FOR MANUFACTURING GLASS AND METHOD FOR MANUFACTURING GLASS USING THE ELECTRIC FURMACE}ELECTRIC FURNACE FOR MANUFACTURING GLASS AND METHOD FOR MANUFACTURING GLASS USING THE ELECTRIC FURMACE}

본 발명은 칸탈을 이용한 유리 제조용 전기용해로 및 이 전기용해로를 이용한 유리제조방법에 관한 것으로서, 보다 상세하게는 일정간격으로 칸탈을 설치하여 투입구로부터 투입되는 유리원료가 용융되면서 배출구로 배출되도록 하는 원리를 이용하여 연속적으로 유리제조가 이루어지도록 한 칸탈을 이용한 유리 제조용 전기용해로 및 이 전기용해로를 이용한 유리제조방법에 관한 것이다.The present invention relates to an electric melting furnace for glass production using cantal and a glass manufacturing method using the electric melting furnace. More specifically, the principle of discharging the glass raw material introduced from the inlet by discharging the inlet is installed at a predetermined interval to discharge into the outlet. The present invention relates to an electric melting furnace for glass production using a cantal, and to a glass manufacturing method using the electric melting furnace.

일반적으로, 유리는 유리원료를 고온에서 용융시킨 후, 청정구역으로 이송시켜 양질의 유리를 제조하게 된다.In general, glass melts the glass raw material at a high temperature, and then transfers the glass to a clean zone to produce high quality glass.

이와 같이, 유리를 제조하기 위하여 유리원료를 용융시키는 로(盧)는 그 가열방식에 따라 여러 종류가 있으나, 최근에는 일정온도를 유지하기가 용이하고, 또한 그 열원이 저렴한 전기를 이용한 로의 보급이 확산되고 있는 추세에 있다.As described above, there are various kinds of furnaces for melting glass raw materials to manufacture glass, depending on the heating method. However, in recent years, it is easy to maintain a constant temperature, and the diffusion of furnaces using electricity with low heat sources is easy. The trend is spreading.

본 발명의 출원인은 상기와 같이 전기를 열원으로 이용한 유리제조용 전기 용해로 및 이 유리 제조용 전기용해로를 이용한 유리제조방법(특허출원 제 2001-11505-5호)를 기출원한 바 있다.The applicant of the present invention has previously filed an electric melting furnace for glass manufacturing using electricity as a heat source and a glass manufacturing method (patent application No. 2001-11505-5) using the electric melting furnace for producing glass as described above.

상기한 유리 제조용 전기용해로는 전원공급장치로부터 전원이 통전되는 전극봉을 직접 유리원료에 접촉되도록 함으로써, 상기 유리원료가 용융되도록 하는 원리를 취하고 있는 것이 특징이다.The electric melting furnace for glass production is characterized by taking the principle that the glass raw material is melted by bringing an electrode rod through which power is supplied from a power supply device to directly contact the glass raw material.

한편, 종래에는 전원의 공급에 따라 고온(대략 1700℃)으로 가열되어 적은 전기의 공급으로도 그 온도를 유지하는 특징을 갖는 칸탈(MoSi2계 초고온용 발열체)을 이용한 전기용해로가 제공되고 있는데, 도 1은 상기의 칸탈을 이용한 유리제조용 도가니형 전기용해로의 내부구조를 개략적으로 도시한 부분사시도이다.On the other hand, there has been conventionally provided an electric melting furnace using a cantal (MoSi 2- based ultra-high temperature heating element) which has a characteristic of being heated to a high temperature (approximately 1700 ° C.) according to a power supply and maintaining the temperature even with a small supply of electricity. 1 is a partial perspective view schematically showing the internal structure of the crucible-type melting furnace for glass manufacturing using the above-mentioned kanthal.

도시된 바와 같이, 내화물(14)의 내측에 도가니(12)가 설치되고, 이 도가니(12)의 주연에 일정간격으로 복수개의 칸탈(16)이 설치되어 있다.As shown in the figure, a crucible 12 is provided inside the refractory 14, and a plurality of cantals 16 are provided at regular intervals on the periphery of the crucible 12. As shown in FIG.

따라서, 상기 도가니(12)에 유리원료를 넣고, 입구를 밀봉한 상태에서 상기 칸탈(16)에 전류가 공급되도록 함으로써, 상기 칸탈(16)에서 발열되는 고온을 이용하여 도가니(12) 내의 유리원료를 용융시키게 된다.Therefore, the glass raw material in the crucible 12 by using a high temperature generated by putting the glass raw material into the crucible 12 and supplying a current to the canal 16 while the inlet is sealed. To melt.

그러나, 상기와 같은 도가니형 전기용해로(10)의 경우, 도가니에 일정량의 유리원료를 넣고 용융시킨 상태에서 별도의 도구를 이용하여 용융된 유리를 꺼낸 후, 다시 유리원료를 넣고 용융시킨 다음 꺼내는 과정을 반복하여야 하는 바, 작업자가 번거로운 문제가 있었고, 또한 많은 양의 유리제조에 한계가 있는 문제점이 있었다.However, in the case of the crucible-type electric melting furnace 10 as described above, the molten glass is taken out using a separate tool in a state in which a predetermined amount of glass raw material is put into the crucible, and then the glass raw material is put in again, melted, and then taken out. To be repeated, there was a problem that the worker has a cumbersome problem, and also had a problem that there is a limit to the production of a large amount of glass.

또한, 상기 도가니에 유리원료 및 용융된 유리의 수납시 칸탈의 온도를 높이거나 낮추어야 함으로써, 전기가 많이 소요되는 바, 궁극적으로 경제적으로도 손실이 초래되는 문제점이 있었다.In addition, when storing the raw material and the molten glass in the crucible to increase or decrease the temperature of the cantal, it takes a lot of electricity, there is a problem that ultimately causes economic losses.

이에, 본 발명은 상기와 같은 제반 문제점들을 해소하기 위하여 안출된 것으로서, 일정간격으로 칸탈을 설치하여 투입구로부터 투입되는 유리원료가 용융되면서 배출구로 배출되도록 하는 원리를 이용하여 연속적으로 유리제조가 이루어지도록 한 칸탈을 이용한 유리 제조용 전기용해로 및 이 전기용해로를 이용한 유리제조방법을 제공하는데 그 목적이 있다.Thus, the present invention was devised in order to solve the above problems, by installing a cantal at a predetermined interval so that the glass material is discharged to the outlet while melting the glass raw material introduced from the inlet so that the glass is made continuously. An object of the present invention is to provide an electric melting furnace for glass production using a cantal and a glass manufacturing method using the electric melting furnace.

이하, 본 발명의 바람직한 일 실시예를 첨부된 예시도면에 의거하여 상세히 설명한다.Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 칸탈을 이용한 유리 제조용 전기용해로의 내부구조를 보인 부분사시도이고, 도 3은 본 발명에 따른 칸탈을 이용한 유리 제조용 전기용해로의 횡단면도이며, 도 4는 본 발명에 따른 칸탈을 이용한 유리 제조용 전기용해로의 종단면도이다.Figure 2 is a partial perspective view showing the internal structure of the electric melting furnace for glass manufacturing using the cantal according to the present invention, Figure 3 is a cross-sectional view of the electric melting furnace for glass manufacturing using the cantal according to the present invention, Figure 4 is a cantal according to the present invention It is a longitudinal cross-sectional view of the electric melting furnace for glass manufacture used.

도시된 바와 같이, 본 발명에 따른 칸탈을 이용한 유리 제조용 전기용해로(20)는 내화벽돌(22)이 대략 직사각형상으로 적재되어 외형을 이루고, 일측에는 유리원료의 투입구(24)가 형성되어 있으며, 이 투입구(24)와 대향되는 위치에는 배출구(28)가 형성되어 있다.As shown, the electric melting furnace 20 for glass manufacturing using the cantal according to the present invention is a refractory brick 22 is stacked in a substantially rectangular shape to form an outer shape, on one side there is formed an inlet 24 of the glass raw material, A discharge port 28 is formed at a position opposite to the injection port 24.

상기 유리 제조용 전기용해로(20)의 하부에는 상기 투입구(24)를 통해 유입된 유리원료가 용융되는 용융실(26)이 형성되어 있는데, 상기 배출구(28)는 이 용융실(26)의 일측에 형성되며, 이 용융실(26)의 상부측에는 양측으로 나란하게 일정간격을 두고 칸탈(32)이 설치되어 있다.A melting chamber 26 is formed in the lower portion of the electric melting furnace 20 for manufacturing glass to melt the glass raw material introduced through the inlet 24, and the outlet 28 is located at one side of the melting chamber 26. On the upper side of the melting chamber 26, the canal 32 is provided at regular intervals in parallel to both sides.

한편, 도 2 또는 도 4에 도시된 바와 같이, 배출구(28)측에는 용융되어 나오는 유리의 양을 조절하기 위한 댐퍼(30)가 슬라이드 가능하게 설치되어 있다.On the other hand, as shown in Fig. 2 or 4, the damper 30 for adjusting the amount of the molten glass is provided on the discharge port 28 side slidably.

따라서, 본 발명에 따른 칸탈을 이용한 유리 제조용 전기용해로(30)를 이용하여 유리를 제조하기 위해서는 먼저, 상기 칸탈(32)에 전류를 통전시켜 고온(대략 1700℃)으로 가온시킨다.Therefore, in order to manufacture glass using the electric melting furnace 30 for glass production using the cantal according to the present invention, first, an electric current is supplied to the cantal 32 to be heated to a high temperature (approximately 1700 ° C.).
