| 1 | USING HIGH Mg-CONTENT CORED-WIRE TO SPHEROIDIZE AND DESULPHURIZE DUCTILE IRON MELT IN INDUSTRIAL EXPERIMENTS显示文摘Mg-content cored-wire was used to desulphurize and spheroidize ductile iron melt in industrial experiments. The optimal feeding speed and suitable treatment temperature were determined in the experiments. And cored-wire method and pouring method were compared. Conclusions have been drawn that, under these conditions in the experiments, the optimal feeding speed is 15m/min, treatment temperature should be as low as possible, 1400-1450℃ generally; and cored-wire method can act more effective in ductile iron melt desulphurization and spheroid than pouring method. | R.Z.Wu B.D.Sun H.J.Ni Y.B.Wu H.S.Wu J.G.Ge | 2004 | Acta Metallurgica Sinica(English Letters)2004，17，6： | 2 |
