关键技术

Key Technology

基于PODFA法原理引进日本介载物分析仪，自行开发了一套夹杂物定量分析软件，并

通过金相显微镜、台式电镜观察夹杂物的形貌进行定性分析。

Based on the principle of PODFA method, a set of quantitative analysis software for

inclusions was developed by introducing Japanese medium carrier analyzer, and the

morphology of inclusions was observed by metallographic microscope and desktop electron

microscope for qualitative analysis.

经过夹杂物分析，可准确快速地对铝合金产品内部有害杂质含量进行定量定性分析，

得到影响铝合金流动性的因素，并依据分级标准，判定夹杂物级别，为改进内部产品

品质提供准确的技术工艺改进路线。

Through inclusion analysis, the content of harmful impurities in aluminum alloy products can

be quantitatively and qualitatively analyzed accurately and quickly, and the factors affecting

the fluidity of aluminum alloy can be obtained. According to the classification standard, the

inclusion level can be determined, which provides an accurate technical process improvement

route for improving the quality of internal products.
