Study of Factors for the Decline in Reduction of Area of 60Si2Mn
Author(s): 
Pages: 16-18
Year: Issue:  2
Journal: WIDE AND HEAVY PLATE

Keyword:  弹簧钢连铸面缩率;
Abstract: 基于对弹簧钢面缩率不合格炉次的工艺条件和低倍试样数据统计,对连铸弹簧钢面缩率降低的影响因素进行了分析,认为其主要原因是铸坯中心碳偏析、夹杂等低倍缺陷所致,而且注意到钢中的氢亦是影响面缩率的重要原因,并根据目前装备情况提出了整改措施,使大规格弹簧面缩合格率达到85%以上.
