In order to identify the reason forwrinkling defects at Q195 cold rolled galvanized steel strip,the large size and micro-size inclusions of samples taken from the various process steps of steelmaking had been characterized by utilizing large sample electrolysis,metallographic microscope,scanning electron microscope （SEM）. The results showed that the cold rolling defects are mainly due to the volume of ladle slag and ladle refractories caused by spalling was confirmed. By improving the process parameters and modify the ladle liner,wrinkling defects of cold rolled products were eliminated.
