目的:探讨高熔铸件浇铸不全的可能原因。方法:通过对临床85件可摘铸件缺损的初浅分析,总结出浇铸不全的可能原因。结果:高熔铸件浇铸不全的原因有以下7个方面:①铸金量不足;②熔金温度过低;③离心力不够;④铸道布局不当;⑤铸件过薄;⑥高温包埋料透气性差;⑦铸圈温度下降。结论:通过查找原因,总结出预防的方法,对提高高熔铸件修复体的质量有一定的作用。
Objective: To investigate the possible causes of incomplete casting of high-melting castings. Methods: Based on the initial analysis of 85 cases of removable castings, the possible causes of incomplete casting were summarized. Results: The reasons for incomplete casting of high-melting castings include the following seven aspects: (1) the amount of castings is insufficient; (2) the melt temperature is too low; (3) the centrifugal force is insufficient; (4) the castings are improperly arranged; (5) the castings are too thin; (6) ; ⑦ casting temperature drop. Conclusion: By finding out the reasons, summed up the prevention methods, to improve the quality of high-melting castings repair a certain role.
