管式炉在使用过程中减压阀的规格操作通气的过程
点击次数:1794 发布时间:2018-08-22
  • 炉管内压力维持在1个标准大气压 , 不可以小于1个标准大气压, 也不可以大于02MPa。可采用此法保证炉管内压力在这个范围内。
  • 气瓶必须安装减压阀、建议选购减压阀量程为01-0.6MPa范围内的减压阀。不可以选过大量程的减压阀(例如0-2.5MPa的),这种减压阀不、容易冲炸石英管。

 

  • 减压阀的压力开到02-0.05MPa比较合适,不可以超过0.05MPa.
  • 当炉温超过1000度时,炉管内不可以真空烧结,维持一个微正压状态气氛保护烧结比较好。
  • 石英管的长时间使用温度建议不要超过1100度。
  • 如果担心气压过大或所烧材料有气体放出,可选用本公司的管式炉防爆系统。
  • 在通气体时、出气口阀门调到大,通过调节进气口阀门或流量计来调节气体流量。
