真空爐石墨加熱棒詳介 列舉真空爐石墨加熱棒的優勢在爐腔這一特定空間內利用真空系統將爐腔內部分物質排出,使爐腔內壓強小于一個標準大氣壓,爐腔內空間從而實現真空狀態,這就是真空爐石墨加熱棒。它具有五大特點:
1、完全消除了加熱過程中工件表面的氧化、脫碳,可獲得無變質層的清潔表面。這對于那些在刃磨時僅磨一面的刀具,如麻花鉆磨削后使溝槽表面的脫碳層直接暴露于刃口,切削性能的改善關系真空爐石墨加熱棒極大。
2、對環境無污染,不需進行三廢處理。
3、爐溫測定、監控精度明顯提高。熱電偶的指示值與爐溫溫度達到±1.5°c。但爐內大批工件不同部位的溫差較大,若采用稀薄氣體強制循環,仍可控制在±5°c溫差范圍內。
4、機電一體化程度高。在溫度測控精度提高的基礎上,工件移動、氣壓調節、功率調節等均可預先編程設定,按步驟實施淬火和回火。
5、能耗顯(xian)著低于(yu)鹽浴爐(lu)。現代先進的(de)真空爐(lu)石墨加(jia)熱(re)棒加(jia)熱(re)室采用優質隔熱(re)材(cai)料制(zhi)成的(de)隔熱(re)墻和(he)屏障(zhang),可將電熱(re)能量高(gao)度集中(zhong)于(yu)加(jia)熱(re)室內,節能效果顯(xian)著。
