摘要

本文对硅酸乙酯、硅溶胶和水玻璃型壳以及以水玻璃涂料为加固层的复合型壳的线量变化规律进行了试验研究。结果认为

型壳线量变化取决于粘结剂、耐火材料和制过工艺。

Abstract

In this paper

the studies are made on the law of dimensional change of ceramic shell mould in investment casting These ceramic shells are as follows : ethyl silicate shell

colloidal silicate shell

sodium silicate shell and its compound ceramic shell

in which the reinfocement. made of sodium silicate coatiag The results have proved that the dimensional change of ceramic shell are decided by binder

refractory are techaique
