class="khcont">過程1 <div id="icyesas" class="para"> 真空淬火真空淬火爐按冷卻方法分為油淬和氣淬兩類，按工位數(shù)分為單室式和雙室式，904山\畏嘲均屬周期式作業(yè)爐。真空油淬爐都是雙室的，后室置電加熱元件，前室的下方置油槽。工件完成加熱、保溫后移入前室，關(guān)閉中門后向前室充入惰性氣至大約2．66%26times;lO ～1．01%26times;10 Pa(200～760mm汞柱)，入油。油淬易引起工件表面變質(zhì)。由于表面活性大，在短暫的高溫油膜作用下即可發(fā)生顯著薄層滲碳，此外，碳黑和油在表面的粘附對(duì)簡(jiǎn)化熱處理流程很不利。真空淬火技術(shù)的發(fā)展主要在于研制性能優(yōu)良、工位單一的氣冷淬火爐。前述雙室式爐亦可用于氣淬(在前室噴氣冷卻)，但雙工位式的操作使大批量裝爐的生產(chǎn)發(fā)生困難，也易在高溫移動(dòng)中引起工件變形或改變工件方位增加淬火變形。
