Abstract：According to the defect detection problem of HE46 cutting tool steel plate,the mechanism of crack defects was analyzed through billet cold acid corrosion test,metallographical observation and composition variation measurement in cross-section.It was determined that serious center segregation led to the formation of martensitic structure,and cracks formed in martensitic,leading to the failure detection of steel plate.By adjusting the electromagnetic stirring parameters,adjusting the hot charge production mode,and assisting vacuum treatment and temperature cutting and stacking technology,the problem of unqualified steel plate inspection caused by steel plate segregation is solved.
