以前,森-美和野村等人曾作为基础研究,在铸锭条件下研究了CO气泡的生成,对于铁在单向凝固时CO气泡的生成作了一系列的研究,考察了CO宏观气泡的生成机理,决定了气泡生成的临界成分。此外,橋浦和森氏等人在铁的凝固速度为5毫米/分的定速单向凝固条件下,研究了CO气泡的生成和消失,研究并比较了CO气泡生成与消灭的机理。因为这些试验都是在定速凝固、且凝固速度很小的条件下进行的,所以,有必要在近似铸锭或连铸的凝固条件下进行研究。本研究就是在这样的凝固条件下,求铁凝固时生成CO气泡的C、O临界成分。为了研究CO气泡的生成机理,把所定的C、O浓
Previously, Mori-Mei and Nomura et al. Used to study the generation of CO bubbles under ingot conditions. A series of studies were conducted on the generation of CO bubbles in the unidirectional solidification of iron. The generation of CO macro bubbles The mechanism determines the critical component of bubble generation. In addition, Bridge and Mori et al. Studied the formation and disappearance of CO bubbles under constant-speed unidirectional solidification conditions at an iron solidification rate of 5 mm / min. The mechanism of generation and elimination of CO bubbles was studied and compared. Because these tests are carried out at a constant rate of solidification and a very low solidification rate, it is necessary to conduct research on the conditions of solidification in the vicinity of ingots or continuous casting. This study is in such a solidification conditions, seeking to iron CO solidification of C, O critical component. In order to study the formation mechanism of CO bubbles, the set C, O concentration
