Abstract
본 발명은 음극선관의 전자총용 슬리브의 제조방법에 관한 것으로서, 제조시간과 공간을 대폭적으로 감소시키고 신뢰성을 향상시킨 것이다. 본 발명의 슬리이브는 몰리브덴 분말을 압축, 성형 및 소결하여 소정의 외경과 두께를 갖는 몰리브덴관을 제조하는 단계와, 이를 강산으로 처리하여 부식시키는 단계와, 인발방식을 통해 소정의 외경과 두께를 갖는 몰리브덴관을 제조한후 절단하는 단계를 통해 제조되는 것을 특징으로 한다.The present invention relates to a method for manufacturing a sleeve for an electron gun of a cathode ray tube, which significantly reduces manufacturing time and space and improves reliability. The sleeve of the present invention is the compression, molding and sintering of the molybdenum powder to produce a molybdenum tube having a predetermined outer diameter and thickness, the step of treating it with a strong acid to corrode, and the drawing method to the predetermined outer diameter and thickness It is characterized in that it is produced through the step of cutting the molybdenum tube having.
