研究减少凝固末期缺陷方法的目的,主要是为了制作各种铸造凝固模型进行模拟实验,找出产生铸造缺陷的机理和减少这种缺陷的方法。至今对此尚有许多不明了之处。本文作者一方面用铸造凝固模型研究减少凝固末期缺
The purpose of studying the methods to reduce the defects in the end of solidification is to make all kinds of casting solidification models and carry out simulation experiments to find out the mechanism of casting defects and ways to reduce such defects. To this still there are many ambiguities. On the one hand, the authors use the cast solidification model to study the reduction of end-stage coagulation
