A new die steel W4Mo3Cr4VRE(0.78～0.88C

3.50～4.50W

2.50～3.50Mo

3.80～4.40Cr

1. 10~1.60V

0.15～0.25RE)was    smelted   by   using   high    speed    steel    filings    of   grinding   DRI(sponge    iron    0.44C-  4.62W-3.27Mo-2.20Cr-0.98V)with   definite   amount   scrap   of   high   speed   steel   turnings(0.87C-3.50W- 1.30Mo- 1.50Cr- 0.60V)in  a  250  kg  induction  furnace  and refined by  ESR.  Examination  results  showed  that with  1180℃ quenched  +  250 ℃  double  tempered  the  HRC  hardness  value  of ESR  steel  was  ≥60

toughness  impact  ≥49  J/cm²

and  with  1150  ℃  or  1180℃ quenched +  560℃ double tempered

the HRC hardness value of ESR  steel was up to  66.The  study results confirm  that it is available to recover and reuse the filings of grinding by magnetic  separation

direct reduction and electric furnace  melting

and the produced new die steel can meet the requirement of application performance of refractory products die.
