在连铸过程中,钢液由盛钢桶经中间包连续不断地注入一个或一组水冷铜制结晶器。注入结晶器的钢液受到强烈冷却后,迅速形成一定形状和坯壳厚度的铸坯。同时结晶器振动引起弯月面钢水周期性流动,使坯壳发生折叠,形成振痕。横裂一般产生于结晶器内,与振痕共生。振痕能产生缺口效应,造成应力集中。振痕深时,振痕波谷
In the continuous casting process, molten steel from the ladle through the tundish continuous injection of a group or a group of water-cooled copper mold. After the molten steel poured into the mold is strongly cooled, the cast slab with a certain shape and thickness of the blank shell is rapidly formed. At the same time mold oscillation caused by the periodic flow of meniscus molten steel, the shell folded, the formation of vibration marks. The transverse cracks usually occur in the mold, which is symbiotic with the vibration marks. Vibration marks can have a notch effect, resulting in stress concentration. Vibration marks deep, vibration marks trough
