| Abstract: | As compared with no-adding Te( 0Te ) steel, in contening 0.005 9% Te(Te/S = 0.098 )Φ38 mm bar of 46MnVS steel rolled from 0480 mm cast bloom the average equivalent diameter and average area of MnS inclusions are increased by 27% and 72% , respectively ， the number of spherical or ellipsoidal inclusions with length-width ratio of 1～3 is increased by 21% ,and the fine sulfide rating decreases from 3.0 to 2.0. Te will be dissolved in MnS to form ( Mn,Te )S, which coarsens and spheroidizes sulfides in steel, to increase ellipsoidal and spindle sulfides in rolled products. The HV10 microhardness value of MnS inclusions increased from 142. 2 to 152.1 by Te modification, to improve the ability of MnS to resist rolling deformation. |
