Claims (2)

텅스텐선을 코일로 감는 코일링공정과, 상기 코일을 알루미나 전해액에 투입하여 통전시킨 뒤 건조시키는 전착공정과, 전착된 코일을 텅스텐 분말이 분산된 침지액에 침지시킨 뒤 건조시키는 침지공정과, 침지된 코일의 불순물을 연소제거시키는 침지공정과, 순차적으로 이루어지는 히이터의 제조방법에 있어서, 상기 전착공정과 침지공정중의 적어도 어느 한 공정에 있어서의 상기 건조가 상온의 공기를 상기 코일에 고속으로 분사함으로써 이뤄지는 것을 특징으로 하는 음극선관 히이터의 제조방법.A coiling process of winding a tungsten wire into a coil, an electrodeposition process in which the coil is put into an alumina electrolyte, and then energized, and an immersion process in which the electrodeposited coil is immersed in an immersion liquid in which tungsten powder is dispersed and dried, In the immersion step of burning and removing the impurities of the used coil and the method of manufacturing a heater sequentially, the drying air in at least one of the electrodeposition step and the immersion step blows air at room temperature to the coil at high speed. Method for producing a cathode ray tube heater, characterized in that is made by. 제1항에 있어서, 상기 공기를 고속으로 분사하는 방법이 5 내지 7kg/㎠ 압력의 공기를 1 내지 5mm 직경의 노즐을 통해 분사함으로써 이뤄지는 것을 특징으로 하는 음극선관 히이터의 제조방법.The method of manufacturing a cathode ray tube heater according to claim 1, wherein the method of injecting the air at high speed is performed by injecting air having a pressure of 5 to 7 kg / cm 2 through a nozzle having a diameter of 1 to 5 mm. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
