본 고안은 새도우마스크를 흑화처리하기 위하여 흑화로의 측벽으로 부착사용되는 히터에 관한 것으로, 보다 상세하게는 히터와 이를 고정하는 흑화로 측벽간에 온도에 따라 적절하게 수축팽창이 이루어지는 수단을 구비함으로서, 히터의 열팽창에 의한 파열손상을 미연에 예방하게 되는 새도우마스크 흑화용 히터에 관한 것이다.The present invention relates to a heater attached to the side wall of the blackening furnace for blackening the shadow mask, and more particularly, by having a means for appropriately expanding and contracting according to the temperature between the heater and the blackening furnace side wall fixing it, The present invention relates to a shadow mask blackening heater which prevents the rupture damage due to thermal expansion of the heater.

일반적으로 새도우마스크는 브라운관에 내설되어 전자총으로부터 발산되는 전자빔을 브라운관 패널 내면에 각기 다른 배열로 도포되어진 형광체에 정확하게 랜딩시켜주기 위한 것이며, 이러한 새도우마스크의 제조에 있어 우선 흑화로에 넣어 소정의 흑화행정을 거치면서 새도우마스크의 강성을 높임과 동시에 부식발생을 억제하게 되는 것으로, 이와 같이 새도우마스크를 흑화처리하기 위한 흑화로의 구성을 제1도를 토대로 간략히 설명하면 이하와 같다.In general, the shadow mask is intended to accurately land the electron beam emitted from the electron gun, which is built into the CRT, onto phosphors coated in different arrangements on the inside of the CRT panel, and is first put in a blackening furnace in the manufacture of the shadow mask. The stiffness of the shadow mask is increased while suppressing the occurrence of corrosion. The configuration of the blackening furnace for blackening the shadow mask as described above is briefly described based on FIG.

즉, 전면이 내화단열벽돌로 구성되어 폐쇄된 공간부(1)를 형성하고, 내부에는 새도우마스크(2)가 다단계로 적충되어지는 선반(3)이 부설되며, 공간부(1) 소정위치에는 스팀장치(미도시) 및 온도계(미도시) 그리고 발열히터(4)등이 내설되는 한편, 측면으로 방사상의 끼움공(la)을 수개 형성한 후 그 내부에 스테인레스재로 구성된 원통형의 부호부재(5)를 압입하며, 상기 부호부재(5)에는 발열히터(4)의 몸체를 끼우게 된다.That is, the front surface is formed of a fire-resistant insulation brick to form a closed space (1), and the shelf (3) in which the shadow mask (2) is stacked in multiple stages is placed therein, and the space (1) in a predetermined position A steam device (not shown), a thermometer (not shown), and a heating heater (4) are installed, and after forming several radial fitting holes (la) on the side, a cylindrical sign member made of stainless steel is formed therein ( 5) is pressed in, and the sign member 5 is fitted to the body of the heating heater (4).

이와 같은 구성을 토대로 부연설명하자면 흑화로(A)에 다수개의 새도우마스크(2)를 공간부(1) 내의 선반에 적층한 후 발열히터(4)에 전원을 인가하여 주면 상기 발열히터가 소정의 온도를 갖는 고열을 발산하여 이를 통하여 새도우마스크의 표면을 까맣게 흑화시켜주는 것이다.Based on the configuration described above, a plurality of shadow masks 2 are stacked on the shelves in the space part 1 in the black fire furnace A, and then the power is applied to the heating heater 4 so that the heating heater is predetermined. By dissipating high temperature with temperature, the surface of the shadow mask is blackened.

그러나, 상기와 같이 흑화로를 통하여 새도우마스크를 흑화처리함에 있어 실질적으로 새도우마스크에 고열을 공급하게 되는 발열히터는 흑화로의 공간부에 노출되어 고열을 발산하는 부위 뿐만 아니라 내화단열벽돌의 끼움공에 끼워진 몸체부위 또한 고열이 발생되는즉, 이는 상기한 발열히터의 몸체부가 고열을 발생함과 동시에 팽창하면서 외주면에 압입되어진 부호부재와 내화단열벽돌로 이루어진 흑화로의 끼움공간과 상호 열팽창계수 차로 인하여 상기한 발열히터의 몸체부위가 흑화로의 측벽에서 파열되었던즉, 이는 원가상승을 초래하는 문제점이 있었다.However, in the blackening process of the shadow mask through the blackening furnace as described above, the exothermic heater, which substantially supplies high heat to the shadow mask, is exposed to the space portion of the blackening furnace and emits high heat as well as the insertion of the refractory insulating brick. The body part inserted into the body also generates high heat, which is due to the difference in the coefficient of thermal expansion and the mutual expansion coefficient between the body of the heating heater, which generates a high temperature and expands at the same time as the body of the blackening furnace made of the sign member and the refractory insulating brick pressed into the outer circumferential surface. The body portion of the heat generating heater was ruptured at the side wall of the blackening furnace, which has a problem of causing a cost increase.

따라서, 본 고안은 상기한 종래의 문제점으로 효과적으로 해결하기 위하여 안출되어진 것으로, 그 목적은 내화단열벽돌로 구성된 흑화로의 끼움공과 이의 내부로 압설되는 발열히터 몸체 사이에 온도에 따라 적절하게 신축 및 팽창되어지는 세라믹 애자관을 삽입함으로 발열히터 몸체의 열팽창계수에 따라 적절하게 신축팽창되어 비교적 열팽창이 적은 흑화로의 측벽에서 팽창압에 의한 발열히터의 파열을 미연에 예방하게 되는 새도우마스크의 흑화용 히터를 제공함에 있다.Therefore, the present invention has been devised to effectively solve the above-described problems, and its purpose is to expand and expand appropriately according to the temperature between the fitting hole of the black fire furnace consisting of fireproof insulation brick and the heating heater body that is pressed into the interior thereof. The blackening heater of the shadow mask which prevents the rupture of the exothermic heater due to the expansion pressure on the sidewall of the blackening furnace which is relatively expanded and expanded according to the thermal expansion coefficient of the exothermic heater body by inserting a ceramic insulator tube. In providing.

상기의 목적을 달성하기 위한 본 고안은 전면이 내화단열벽돌로 구성되어 폐쇄된 공간부를 형성하고, 내부에는 새도우마스크가 다단계로 적층되어지는 선반이 부설되며, 측면 내화단열벽돌에는 방사상의 끼움공을 수개 천공하고, 상기 끼움공으로는 대응되는 개수를 갖는 발열히터가 압설되어진 흑화로에 있어서, 상기 끼움공과 발열히터 사이에 온도에 따라 자유로운 신축,팽창이 이루어지는 원통형의 세라믹애자관이 설치되어진 특징이 있다.The present invention for achieving the above object is composed of a refractory insulating brick in the front is formed a closed space, inside the shelf is laid a stack of shadow masks in multiple stages, the side of the refractory insulating brick radial fitting holes In the black fired furnace in which a plurality of perforations and a corresponding number of exothermic heaters are pressed into the fitting holes, a cylindrical ceramic insulator tube is provided between the fitting hole and the exothermic heater, which is freely stretched and expanded according to temperature. .
