摘要

分析了中温模料组分的氧化特性。在模料反复使用过程中

高温脱蜡、高温搅拌除水是模料氧化变质的主要原因。随着模料的逐渐氧化

除水变得越来越难

灰分、收缩率、粘度越来越高

严重影响铸件的质量。合理的处理工艺可以减缓模料的氧化。

Abstract

The oxidation characteristics of medium-temperature pattern material for investment casting was summarized.In the process of repeated use of pattern material

the oxidation deterioration was resulted from the high temperature in the process of dewaxing and water removal.With the gradually oxidation of the pattern material

its water removal is more and more difficult

and its ash content

shrinkage and viscosity is higher and higher

thus the cast quality is deteriorated greatly.The rational process for dewaxing and water removal can be helpful for the oxidation slowdown.
