三项埋入式电极盐浴炉采用盐类作加热剂，根据不同的工作温度，可选用不同成份的盐或混合盐，盐在熔化前是不导电的，因此盐浴炉使用时必须使用起动电极溶化，由于电流通过导电的溶盐不断产生热量，故可保持溶化状态，因电极在电磁力的作用下，通过自然对流和电磁搅拌而使熔盐不断循环，故可迅速和均匀的加热工件。

The main results were obtained as follows:(1) The calculation results of temperature field indicate that, 6139T radiator was brazed using the stage-by-stage heating process, while 6204T radiator with a larger size was brazed using the temperature difference heating process. The uniform temperature distributions in faying faces were all obtained. And the temperatures were in the range of brazing temperature. It is proved that the finite element models established are reasonable.

取得的主要结果和结论为：(1)温度场计算结果表明，对于6139T散热器，采用分阶段加热钎焊工艺，而对于具有较大尺寸的6204T散热器，采用温差法加热钎焊工艺时，均获得了均匀的钎焊面温度分布，且在钎焊温度范围之内，证明所建立的有限元分析模型是合理的。

Using high frequency induction brazing and TiZrNiCu filler metal, the shear strengths of the joints were low. The maximum shear strengh was only 102.1MPa, which was lower than the maximum strength of vacuum brazing. The reasons may be that excessive intermetallics, holes and oxidation existed in the joint. So TiZrNiCu filler metal isn't fit for non-vacuum brazing.The stress variation, stress distribution and crack-sensitive regions during the cooling process of brazing have been studied by Marc non-linear software.

采用气体保护高频感应加热、TiZrNiCu钎料钎焊时，接头的强度普遍偏低，最高的剪切强度只有102.1MPa，远远低于辐射加热真空钎焊的强度，其原因是接头中局部生成了过量的金属间化合物，且产生氧化，接头中含有较多的气孔等影响了接头强度，因此可以认为TiZrNiCu钎料不适合在非真空条件下的钎焊。
