铸造时金属未能占满蜡模型腔以致完成的铸件出现部分缺损称为铸造不全。 铸造不全虽非高熔合金铸造的常见缺陷,但这种缺陷的发生原因多数只是出于一些微小的差错,因而常常使人倍感沮丧。 我们开展高熔合金铸造工艺五,六年以来,曾发生过一些铸造不全的症例,本文的目的在于分析其发生原因并提出防止其发生的注意点,供同道参考。 实例分析 例1 铸件原设计金属基板,65联卡,3|4隙卡。浇铸失败,基板大部失 Cast metal failure to fill the wax cavity so that the finished part of the casting defects known as incomplete casting. Casting incomplete Although not common defects in high-fusion alloy casting, but most of these defects occur only because of some minor errors, which often make people feel frustrated. We carry out high-fusion alloy casting process five or six years, there have been some cases of incomplete casting, the purpose of this paper is to analyze its causes and put forward to prevent its occurrence of points for fellow reference. Example Analysis Example 1 cast original design metal substrate, 65-card, 3 | 4-slot card. Casting failure, most of the substrate loss
