中国工程院院士胡正寰教授,国家级有突出贡献的中青年专家,1934年7月生,1957年毕业于北京钢铁学院冶金机械专业并留校任教至今。现为北京科技大学零件轧制研究中心主任,博士生寻师,兼任国家科委《高效零件轧制研究与推广中心》主任,全国锻压学会常务理事、副理事长,北京市政协第5、6、7、8届委员,北京市政府专业技术顾问。胡正寰教授长期从事轴类零件轧制(斜轧与楔横轧)这一高新领域的研究,经过近40年的不懈工作,以新型的轧制工艺替代了传统的锻造与切削工艺生产机器零件,并在长期研究与实践应用的基础上建立起零件轧制技术的学术体系,既是冶金轧制又是机械制造的新发展,届交叉学科,使我国成为世界上三 Chinese Academy of Engineering Professor Hu Zhenghuan, a national outstanding contribution of young and middle-aged expert, born in July 1934, 1957 graduated from the Beijing Institute of Iron and Steel Metallurgy Machinery and teaching so far. Beijing University of Science and Technology is now rolling research center director, doctoral student search, as the State Science and Technology Commission, “efficient parts rolling Research and Extension Center,” director of the National Forging Society executive director, vice chairman of the CPPCC Beijing Municipal Committee 5,6 , 7, 8 members, Beijing municipal government professional and technical consultants. Professor Hu Zhenghuan has long been engaged in the research of high-tech fields of shaft parts rolling (cross-rolling and cross-wedge rolling). After nearly 40 years of unremitting work, the new rolling technology has replaced the traditional forging and cutting production machinery parts, Based on long-term research and practical application, the academic system of part rolling technology is established. It is not only a new development of metallurgy and rolling but also a new interdisciplinary discipline, making our country the world’s third
