軋輥低溫強化處理?大型冷軋輥超低溫強化處理裝置、軋輥低溫強化處理


? ? 軋輥深冷處理是對軋棍進行的深冷處理。冷軋輥淬火后一部分母相會以殘余奧氏體形式保留下來,只有繼續降溫以增加相變的驅動力,才能繼續獲得馬氏體,降低 殘余奧氏體含量。深冷處理通過致冷設備進行。將軋輥放在一個四壁襯有保溫材料的容器即冷凍槽內,通過制冷方法可把槽內軋輥的溫度降至-190℃以下的溫度。

????本設備采用國際優越的溫控技術,預先設定的工藝時間,處理時間有控制系統計時。處理效果可用金相實測判定,殘余奧氏體含量低于規定值即可,一般允許8%一 10%,嚴格場合則要求5%以下。殘余奧氏體并非越低越好,有恰當數量時對韌性和抗事故性都是有利的。

? ? 通常的應用目的是通過深冷處理/冷處理以增強金屬工件的耐磨性和尺寸穩定性,使軋輥、刀具、刃具、模具、精密機械零件、油嘴、齒輪、軸承等的使用壽命得到若干倍地提高。????-196℃液氮深冷處理可使組織發生明顯變化,有效促使殘留奧氏體向馬氏體轉變及超細碳化物的析出,使產品獲得較佳的綜合力學性能,深冷處理后產品的使用壽命較常規熱處理提高四倍以上,具有十分重要的使用價值。

軋輥低溫強化處理介紹:?
????深冷處理技術是近年來興起的一種改善金屬工件性能的新工藝。所謂深冷處理,就是用液氮(-196℃)作為冷卻介質將淬火后的金屬材料的冷卻過程繼續下去,達到遠低于室溫的某一溫度,促使常規熱處理后所存在的殘余奧氏體得到進一步轉化成能使鋼變硬、增強的馬氏體,從而改善金屬材料性能。深冷處理后能明顯的提高金屬工具的耐磨性、韌性和尺寸穩定性,使工件的使用壽命成倍的提高。?
???軋輥低溫強化處理的改進效果是滲入處理件的內部(整體效應),不限于表面,所以對刃具進行重磨再用時,不會使工件的改性效果失效;對工件的形狀和尺寸不但不會引起變化,而且有增強尺寸穩定性和減小淬火應力的作用;工藝系統簡便,耗電量少,不受工件的形狀和尺寸限制,操作簡便;無任何環境污染,是完全的環保型技術。?
????深冷處理技術一出現,就引起了科學研究界和工業界的高度重視,在國外已應用于刃具、量具、模具以及精密零件,如油泵的油嘴、發動機的渦輪軸、軋輥、閥門、齒輪、彈簧等工件的改性。深冷改性技術的應用正逐步得到企業界的重視和發展.?
????在美國、前蘇聯、日本等國,不但把深冷技術用于高速鋼、軸承鋼、模具鋼,以提高材料的耐磨性和強韌性,進而提高工件的整體使用壽命,同時還利用深冷技術對鋁合金、銅合金、硬質合金、塑料、橡膠、瀝青、玻璃等進行深冷改性。改善均勻性、穩定尺寸、減小變形、提高使用壽命。?
