陶瓷型的尺寸精度直接影响铸件的尺寸精度。陶瓷型的尺寸精度受铸件结构、浆料体系、模型的尺寸精度、模型保持时间、喷烧及焙烧方法等因素影响。本文着重从浆料体系的角度探讨起模硬度对陶瓷型尺寸精度的影响。 陶瓷型的浆料体系由耐火材料、硅酸乙酯水解液、催化剂和附加物组成。浆料体系的硬化过程是一个动态过程,该过程进行到一定时候,达到动态平衡,在这之后起模, Ceramic-type dimensional accuracy directly affects the dimensional accuracy of the casting. The dimensional accuracy of the ceramic type is influenced by factors such as the structure of the casting, the size of the slurry system, the dimensional accuracy of the model, the holding time of the model, the burning and burning methods, and the like. This article focuses on the slurry system from the perspective of the impact of die hardness on the dimensional accuracy of the ceramic. The ceramic slurry system consists of refractory material, ethyl silicate hydrolyzate, catalyst and additives. Slurry system hardening process is a dynamic process, the process to a certain time, to achieve dynamic balance, after which the mold,
