Based on the underground of high efficient CC in Ma 'steel, the longitudinal surface crack and centerline crack, the uppermost defects of beam blank CC production are studied.
针对马钢异型坯高效连铸的背景,分析了异型坯生产中铸坯质量的主要缺陷类型:表面纵裂和中心裂纹。
When applied high frequency pulse current on CC. billet, the centerline pipe and centerline crack in billet are eliminated, and the central segregation and middle crack are improved.
用高频电场处理连铸小方坯,可以消除铸坯中心缩孔和中心裂纹。改善中心偏析和中间裂纹。
When high frequency pulse current is applied to CC billet, the centerline pipe and centerline crack in the billet are eliminated, and the central segregation and central crack are reduced.
进行了连铸工业试验,效果明显:铸坯中心缩孔和中心裂纹被消除,中心偏析和中间裂纹也得到降低。
This is formed by the cracks oscillating about the centerline in the direction of crack propagation.
这是由于在裂纹的传播过程中,裂纹尖端沿着传播方向的中线上下振荡所形成的。
