硅溶胶壳型工艺的研究

Study on the Process for Preparing Silicasol Shell Mould

对用于制造定向凝固空心无余量叶片的高温壳型，即８１１Ａ氧化铝壳型，在生产中出现的问题进行了分析，提出了涂料配制、壳型干燥等方面的改进措施。

This paper studies the influence of processing parameters on properties of the shell mould in producing a hollow turbine blade by directional solidification, and optimizes the parameters. The strength of shell mould is greatly improved.
