style="text-indent:25px">在工程設計中，通常都是通過增大強冷系統(tǒng)的功率和換熱器的面積來提高真空爐的冷卻速率，這樣也就導致了換熱器結構和風機結構體積過大。另外，強冷系統(tǒng)工作時，被冷工件的表面降溫均勻性對工件的組織結構有重要影響，一般解決此類問題的方法是在爐膽上增加環(huán)向噴嘴，但是由于風阻的增加，使降溫效率大打折扣。調研國外真空爐強冷系統(tǒng)的結構時發(fā)現(xiàn)，國外普遍使用的氣流換向結構比以上提及的兩種結構在冷卻效率、工件降溫均勻性方面有較大提升。真空爐在爐腔這一特定空間內利用真空系統(tǒng)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。</p><div

style="text-indent:25px">臥式真空回火爐加熱過程中的注意事項：在測試爐溫均勻性時，應注意溫度測量觸點的位置和捆綁以及與加熱元件的距離。在箱式電阻爐中，經常使用刷子、掃帚、壓縮空氣和真空吸塵器清潔爐缸和貨架磚。應避爐內氧化皮等雜質落在電熱元件上，使架磚短路致燃燒。底板、坩堝、爐子和其他耐熱鋼構件使用段時間，以便敲擊以去氧化皮。如果不及時清理氧化鐵垢等雜質，它們會熔化并與耐火磚反應，熔化爐絲。回火爐加熱后長時間不能開門。當溫度高于400℃時，不應快速冷卻。河南大型真空爐價格</p></p><br
