四川多用爐使用的氣體滲碳是在富碳介質中使碳滲入低碳(cD(C)一0．1～0．3)或低碳合金鋼的表面，使其在保持心部強韌性的條件下獲得高硬度的表層，從而提高工件的耐磨性和疲勞強度，是車輛傳動件常采用的熱處理方法之一。但傳統的低壓真空滲碳爐使用的氣體滲碳方法突出的弊端是工藝時間長，能源消耗大，已成為廣大熱處理工作者長期以來不斷探索解決的問題。感應加熱內熱式真空滲碳是將氣體滲碳、真空熱處理、感應加熱技術在新的平臺上進行集成創新，多用爐廠家建立(li)一種全新的金屬表面強化工藝，即通(tong)過(guo)(guo)采(cai)用高(gao)效的感應加熱(re)方式實現(xian)快(kuai)速(su)(su)加熱(re)；通(tong)過(guo)(guo)將感應線圈(quan)放置在(zai)爐(lu)內實現(xian)僅對工件(jian)(jian)加熱(re)，而爐(lu)內其他部分及爐(lu)體(ti)(ti)溫度較(jiao)低，達到能(neng)(neng)源的較(jiao)大利用和爐(lu)體(ti)(ti)結(jie)構的簡化；通(tong)過(guo)(guo)在(zai)真空環境下的加熱(re)和通(tong)人滲碳氣體(ti)(ti)，實現(xian)工件(jian)(jian)表面的凈化和活(huo)化，達到碳原子的快(kuai)速(su)(su)吸收和較(jiao)小的變形(xing)，實現(xian)優(you)質、高(gao)效、節能(neng)(neng)、降耗、減污的先進化學(xue)熱(re)處理生產。
