class="khcont8">　　比如。對于中小精密管，淬火硬度不足往往是中高溫階段冷速不足所致，而模數(shù)大精密管要求較深淬硬層時，提高低溫冷卻速度就非常必要了。對于淬火，一般說，蒸氣膜階段短、中溫冷速快、且低溫冷卻速度快，往往能獲得高而且均勻淬火硬度和足夠淬硬深度。　　精密管裝掛方式對淬火冷卻效果也有明顯影響。要使淬火流動通暢，并備和使好攪拌裝置，才能得到更好效果。提高所淬火介質低溫冷卻速度，往往可以增大淬硬層深度。在滲層碳濃度分布相同情況下，采低溫冷卻速度更高淬火，往往獲得更深淬火硬化層，因此，采冷卻速度快淬火后，可以相縮短精密管滲碳時間，也能獲得要求淬火硬化層深度。　　要求滲碳淬硬層深度越大，這種方法縮短滲碳時間效果越明顯。2．淬火后心部硬度過高這類問題可能與所選介質冷速過快或介質低溫冷卻速度過高有關。解決法之一是改換淬火來滿足要求。法之二是與淬火介質生產廠家聯(lián)系，有針對地加入適當添加劑來降低淬火中低溫冷卻速度。　　法之三是改淬透性更低鋼種。3．淬火變形問題淬火變形使不少工廠傷透了腦筋。按習慣，變形問題解決通常要牽涉多個部門，解決法往往是綜合措施。近發(fā)表了關于淬火變形，精密管把引起變形因主要歸結為冷卻速度不足和冷卻不均，并在此基礎上提了提高冷卻速度并設法實現(xiàn)均勻冷卻解決則方法，可供參考。

class="khcont">　　鋼管性能更優(yōu)越，金屬比較密。冷拔成品精度高，表面質量好。鋼管橫面積更復雜。鋼管性能更優(yōu)越，金屬比較密。精密鋼管計算公式::[(外-壁厚)*壁厚]*0.02466=kg/米(每米重量)熱處理工藝折疊編輯本段前奏折疊真空退火優(yōu)質彈簧鋼、工具鋼、精密鋼管絲材，不銹鋼制品及鈦合金材，作光亮退火均可采真空處理。　　退火溫度愈低，則要求真空度愈高。為防止鉻蒸發(fā)及加速熱傳導，一般采載氣加熱(保溫)法，并注意對不銹鋼和鈦合金不宜氮而采氬氣。過程折疊真空淬火真空淬火爐按冷卻方法分為淬和氣淬兩類，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。　　真空淬爐都是雙室，后室置電加熱元件，前室下方置槽。工件完成加熱、保溫后移入前室，關閉中門后向前室充入惰性氣至大約66%26times;lO~01%26times;10Pa(200~760mm柱)，入。淬易引起工件表面變質。由于表面活性大，在短暫高溫膜作下即可發(fā)生顯著薄層滲碳，此外，碳黑和在表面粘附對簡化熱處理流程很不利。　　真空淬火技術發(fā)展主要在于研制性能優(yōu)良、工位單一氣冷淬火爐。前述雙室式爐亦可于氣淬(在前室噴氣冷卻)，但雙工位式操作使大批量裝爐生產發(fā)生困難，也易在高溫移動中引起工件變形或改變工件方位增加淬火變形。
