摘要
研究了ＢＮｉ－２钎焊条真空吸铸原理，并由试验得出：当ＢＮｉ－２合金加热到１５００℃，真空控制阀门开口为Φ６ｍｍ以上，真空度５０ＫＰａ，铸型预热温度５００℃，并用Φ内２ｍｍ×５００ｍｍ石英管进行真空吸铸时，吸铸高度可达到４０ｃｍ以上。
Technological principle of the suction casting for BNi-2 filler rod has been studied The experimental results show that the suction casting process of BNi-2 filler rod is that when BNi-2 alloy is heated to 1500℃, the calibre size of vacuum value is more than Φ6mm, the vacuum is 50kPaand the preheat temperature of mould is 500℃, more than 400mm in height of suction casting can be reached with quartz glass tube of Φ2mm×500mm
