建所三十年来,我们在压力加工的理论和生产实践上做了不少工作,许多研究成果已在国内外的学术刊物上发表,不少还在生产上推广应用。现在把这些研究工作的概况介绍如下: 一、球墨铸铁的研究在五十年代初期,球墨铸铁是一种新型的机械制造材料。由于有优良的机械性能,可以用来代替可锻铸铁和一部分铸钢、锻钢,所以当时我国和世界各国都展开了研究工作。由于球墨铸铁的性能和铸钢很相似,便引起了能否进行压力加工的问题。我们首先在不同温度下
Since its establishment 30 years ago, we have done a lot of work in the theory and practice of pressure processing. Many of the research results have been published in academic journals at home and abroad. Many of them have been popularized and applied in production. Now the overview of these research work is as follows: First, the study of ductile iron In the early 1950s, ductile iron is a new type of mechanical manufacturing materials. Because of its excellent mechanical properties, it can be used to replace malleable iron and a part of cast steel and forged steel, so at that time, China and other countries in the world started their research. Due to the very similar properties of ductile cast iron to cast steel, the problem of being able to carry out press working has been raised. We are first at different temperatures
