熔模铸造用石英粉粒度分布的研究

The study of Silica Flour Used in Investment Casting Tsinghua University

本文介绍了粉粒度对涂料、型壳性能的影响,可用粗、细粉配成性能好的混合粉,它所做铸件表面粗糙度较小。

The influence of particle size of silica flour on the properties of coating and shell has been introduced in this paper. In order to improve surface finishment of casting,one can use the mixture of coares and fine flour ,because the mixfure has better properties .
