METHOD FOR MANUFACTURING STICK-TYPE CERAMIC FIBER ELECTRIC HEATING ELEMENT AND STICK-TYPE CERAMIC FIBER ELECTRIC HEATING ELEMENT
Provided are a method of manufacturing a stick-type ceramic fiber electric heating element and a stick-type ceramic fiber electric heating element. To manufacture a stick-type ceramic fiber electric heating element which is able to rapidly increase temperature to no less than 1,000 degrees within dozens of seconds through the inter-fiber binding induction and uniform orientation of SiC fibers stably used at no less than 1000°C, a bundle of green fibers is prepared and cut in a specific size, the fiber bundle is oriented in a mold having both open sides and an open upper part in one direction, the open upper part of the mold is closed with an upper cover with constantly controlled weight, thermal oxidation stabilization is performed in the mold filled with the fibers, the fibers are thermally treated in an inert gas atmosphere after the completion of the stabilization, and the fibers are cooled at a room temperature after thermal treatment. The stick-type ceramic fiber electric heating element, in which ceramic fibers are oriented in one direction, includes: one end and the other end which can come into contact with electrodes from both sides; and ceramic fibers extended from one end to the other end of the electric heating element.
1000 ℃ 이상 고온에서 안정하게 사용할 수 있는 SiC 섬유를 균일한 배향 및 섬유간 결합유도를 통해서 수십초 이내에 순간 1000도 이상까지 급승온이 가능한 스틱형 세라믹 섬유 전기발열체를 위해, 그린 파이버 다발을 준비하여 특정 사이즈로 자르고, 얻어진 섬유 다발을 양쪽이 오픈되고 상부가 오픈된 몰드에 일방향으로 배향하고, 몰드의 오픈된 상부를 무게가 일정하게 제어된 상부 덮개로 덮고, 섬유가 장입된 몰드에 대해 열산화안정화를 진행하고, 안정화가 완료된 후 불활성가스 분위기에서 열처리를 진행하고, 열처리 후에 상온으로 냉각하는 스틱형 세라믹 섬유 전기발열체의 제조방법과, 세라믹 섬유가 일방향으로 배향된 스틱형 세라믹 섬유 전기발열체로, 전기발열체는, 양쪽에서 전극에 접촉할 수 있는 일단 및 타단을 갖고, 전기발열체의 일단으로부터 타단까지 연장된 세라믹 섬유를 포함하는 스틱형 세라믹 섬유 전기발열체를 제공한다
