Abstrak

The φ110 mm bar products of steel 3Cr2W8V were forged from 740 kg ingot melted by 15 t EAF and re- fined by 25 t LF. At end of refining period,the oxygen content in steel was 29×10<sup>-6</sup>and the liquid steel was treated by rare earth treatment with adding 0.048% RE alloy(21~24RE,44Si,3Mn,5Ca,3Ti,bal Fe). The yield of rare earth elements was 30.78%.The examination results showed that the rare earth treatment could be effciently to improve segregation of eutectic carbides in die steel 3Cr2W8V and obviously to decrease segregation of deleterious elements such as P,Pb, Sn,As,Sb at grain boundary.
