Abstract Inclusions in SPHE continuous casting slab were tested and analyzed by dendrite corrosion, cold acid etching, hot acid etching, OM(optical microscope), SEM(scanning electron microscope), EDS(energy dispersive spectrometer) and so on. The inclusions aggregation zone was found in 1/4 of inner arc in thickness of continuous casting slab, the composition of inclusions was main Al2O3, whose size was small. Some measures of reducing inclusions defect in continuous casting slab were proposed.
