Abstract:The surface cracks in microalloyed steel plates were observed and analysized through metallographic microscope, SEM and energy spectrometer. The results show that there are oxide and decarburization near cracks, and some casting powder lies in the cracks, which proves that the microcracks and slag inclusion on slab are the cause of surface cracks. Some suggestions were proposed to reduce these cracks.
