In the process of high temperature eutectic point development, the common pouring methods include direct eutectic method and pre eutectic method. In this paper, two kinds of filling accessories are designed, one is direct eutectic crucible with long graphite liner, and the other is pre eutectic crucible with special structure. The experimental results show that the former can significantly improve the perfusion efficiency of direct eutectic method, and the latter can effectively avoid the eutectic bonding problem of pre eutectic method. Both of them have achieved the design purpose, and have played a promoting role in the development of high temperature eutectic point technology.
