铸造工业在我国已有数千年的历史,但由于缺乏正确理论指导和合理设计方法,至今仍比较落后,生产一个产品,往往多次浇铸还不能合格。从一九七八年开始,我院金属材料工程系的教师和科研人员同秦川机床厂、西安球墨铸铁厂的技术人员一起,把解决这个老大难问题作为主攻课题,进行了长期的系统研究,终于找到解决办法,提出了铸铁件均衡凝固理论和有限补缩原则,并且设计出压边浇冒口系统动态充填过程的数学模型和电子计算机数值摸拟程序。这一新的工艺理论和设计方法,很快受到全国许多同行专家的重视。不少生产部门积极
Foundry industry in our country for thousands of years of history, but due to the lack of correct theoretical guidance and rational design methods, is still relatively backward, producing a product, often casting can not be qualified. Since 1978, teachers and researchers of the Department of Metal Materials Engineering in our hospital, together with the technicians of Qinchuan Machine Tool Plant and Xi’an Ductile Iron Casting Factory, have made systematic and long-term systematic studies on the solution to this persistent problem , The solution was finally found, the theory of equilibrium solidification of cast iron and the principle of finite shrinkage were put forward, and the mathematic model and numerical simulation program of the dynamic filling process of the ramming system were designed. This new process theory and design methodology quickly gained the attention of many peer experts across the country. Many production departments are active
