0.040Als) at both side distance 500 mm from broad face center of 300 mm X 1950 mm slab mold. Analysis results show that the yield of RE is more than 95%
the distribution of RE in steel is uniform
the inclusions in steel is modified and most inclusions are spheroidal; as compared with quenched-tempered non-adding RE steel 30CrMnMo
the impact energy ( KV2) at -40℃ of quenched-tempered 60mm plate steel 30CrMnMo containing 0.017% RE increases from 50.9~56.6 J to 77.6~81.6 J.
