Claims (4)

  1. 원통형상의 히이터 및 이히이터의 주위에 원통형상의 단열재를 가진 고온로에 있어서, 이 단열재는 열전도성에 관해서 이방성을 지니고, 또한 열전도율이 작은 방향과 온도구배가 큰 방향을 일치시킨 것을 특징으로 하는 고온로의 단열방법.
  2. 제1항에 있어서, 상기 단열재는, 카아본 또는 석영, 알루미나등의 세라믹섬유의 배열을 맞춤으로써 상기 이방성을 부여하게 되는 것을 특징으로 하는 고온로의 단열방법.
  3. 제2항에 있어서, 상기 단열재는, 섬유를 일방향으로 배열시킨 복수의 부분으로 구성되고, 각 부분의 조합에 의하여 상기 섬유의 배열방향을 달라지게 한 것을 특징으로 하는 고온로의 단열방법.
  4. 제1항에 있어서, 상기 단열재는 두께방향으로 열전도율이 작은 적외선반사시이트를 층형상으로 포개어 형성되는 것을 특징으로 하는 고온로의 단열방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
