摘　　要：基于“智慧芽”平台专利数据预判铸造领域的前沿热点技术,分析其全球分布情况及发展态势;采用可视化方法展示细分领域的重点研发团队与技术创新状况,分析其技术实力和核心技术竞争力,发现与之核心技术相关联的机构。结果表明:日本、美国、德国高价值专利遥遥领先,中国铸造技术专利数量较多,但质量有待提升;铸造前沿热点技术主要集中在高温合金及轻合金精密铸造成形、铸件质量检测和铸模制造等技术方向;其高温合金与钛合金铸件的应用主要集中在航空航天领域,大型复杂铝、镁、钛轻合金铸件的应用主要集中在汽车、轨道交通及医疗器械等领域。The developing hotspots of advanced foundry technology and its global distribution and development trend are analyzed based on the patent data of Patsnap platform. Besides, the visualization method has been used to show the key research teams and technology innovation status in the subdivision, to measure the technical strength and core competitiveness, and find out the institutions related to the core technology. The research results indicate that: Japan, the United States and Germany are far ahead in terms of high-value patents;China has a large number of foundry technology patents, but the quality remains to be improved. The cutting-edge hot technologies in foundry industry mainly focus on the precision casting of superalloys and light alloys, casting quality inspection and mold manufacturing and so on. The application of the superalloy and titanium alloy castings is mainly concentrated in the aerospace field, large complex aluminum, magnesium and titanium light alloy castings in automobile, rail transit and medical equipment fields.
