真空定向凝固爐
設備用途及原理
本系列真空定向凝固爐是在真空條件下利用中頻感應加熱對其金屬或合金進行熔化，利用特殊設計的保溫爐和冷卻系統形成熱梯度，通過下拉機構來制備定向凝固和單晶零件的現代化設備。它能夠嚴格地控制材料的溫度和合金成份。
其熔化爐部分具有快速熔化的功能,使元素的燒損降到最低。為獲得最高的溫度梯度和平整的凝固界面，采用了特殊設計的結構來滿足其溫度梯度的要求。主要用于生產銀基，鎳基、鐵基、鈷基超高溫合金，這些合金制造的高質量的產品被廣泛應用于航空渦輪發動機產業、汽車、生物醫學、化學和休閑娛樂等行業。保溫爐可以設計成二段或三段的結構，冷卻段可以設計成水冷套或低熔點的液體金屬。
Application and Principles
This series of vacuum directional solidifying furnace is a modern equipment working for melting metal or alloy with medium-frequency induction heating under vacuum, forming thermal gradient with specialized-designing holding furnace and cooling system, and preparation for directional solidified and single-crystal parts by pulling down mechanism. It can strictly control the temperature and alloy content of materials.
Its furnace possesses the function of fast melting, minimizing the melting loss of elements.
To obtain highest temperature gradient and smooth solidifying interface, it is adopted with special designing to its requirement for temperature gradient.
This equipment is primarily applied to the production of silver-based, nickel-based, iron-based, and cobalt-based high-temperature alloys, and the high-quality products made of these alloys are commonly practiced into aerospace turbine engine industry, vehicle, bio-medical field, chemistry field and entertaining fields. Holding furnace can be designed as two-stage or three-stage structure. And its cooling stage can be designed as water jacket or liquefied metal with low melting point.
