چکیده    The main objective of this project was to investigate the behavior and the damaging effects of hot tear segregationsin the continuously cast steel blooms on the final product quality. to achieve this aim, plant data from three differenttypes of steels were used. investigations using the scanning electron microscope (sem) equipped with energydispersive x-ray spectroscopy (eds) probe and metallographic techniques showed that during the subsequentstages of the cast products, the hot tear segregations were transformed into spherical shapes, joined to each otherand moved toward the surface. also, it was observed that hot tear segregations affected the final product qualityin two ways: (1) they could cause uneven surfaces in the final products, and (2) if they reached the surface in aline oriented pattern, they could make a surface crack. the hot tear segregations located near the surface couldbe crushed to the smaller ones during the rolling. this phenomenon made hot tear segregations less destructive.
