  [2] 1)爐內的氧化皮經常用毛刷、掃帚或壓縮空氣清除幹凈,以防落在合金元件上而發生短路,一般每月清掃不應少於一次。
  2)底板、柑竭、爐罐等耐熱鋼構件每經使用一段時間,好吊起敲擊,清除其氧化鐵皮,以免崩及或埋沒元件。尤其是鉻錳氮鋼,用到後期時剝落更為嚴重。
  3)箱式爐滬門的下齒和並式爐爐蓋的環刀嚴密插入砂封槽內,砂封內的砂子不能裝得過滿,並要平正。如掉入爐內砂子,則應及時清理。對低溫爐,則可墊上一層完好的石棉繩襯墊。
  4)外熱式鹽浴爐應定期吊出柑渦,清除熔鹽。元件表面的凝鹽可用熱水清洗;擱磚上的凝鹽則可採用刮除的方法清除。
  5)黃銅保溫爐的爐蓋對接嚴密,防止“銅霜”掉入爐膛而侵蝕元件。
  6)避免銅、鋁、鋅、錫、鉛等有色金屬與電熱元件接觸,無論是細粉、熔液或蒸汽,在高溫時對元件的侵蝕都是十分有害的。這是因為被侵蝕的部位形成“麻坑”,截面變小,後由於過熱而燒斷。
  7)升降式電退火爐用小車蓋板應壓蓋嚴密,以防.鑄件退火時掉入砂子將元件埋沒而發生過熱熔化。因此,經常檢查,並及時清除積砂。
  8)由於升溫停爐時的熱脹冷縮以及蠕變伸長等,引出棒接線夾子的螺栓容易發生氧化松動,應該定期檢查並擰緊。
  9)引出棒孔要堵塞嚴密,以免漏出保護氣體在此燃燒,引起棒體氧化掉皮,以致引出棒與夾子接觸不良。
  10)在無罐滲碳爐或採用含CO的可控氣氛時,會發生碳的遊離而導致短路。故應經常開啟爐門或定期用壓縮空氣進行吹洗,使碳的燃燒物及時燒掉。
