摘要
自行研究和设计了交替变向电磁场装置。将采用稀土镁球化处理后的铁水,经不同保温时间后,分别在重力场和电磁场中凝固,利用对比试验的方法考察电磁场对球墨铸铁球化衰退的影响规律。结果表明:交替变向电磁场可加速球化元素镁和稀土的脱S脱O作用,使电磁场中凝固的球墨铸铁S,O含量相对较低,从而抑制了球墨铸铁的球化衰退。
The rare earth magnesium spheroidized liquid iron was held for 0, 10, 30 min and solidified in gravity field and alternative electromagnetic field by means of self-designed alternative electromagnetic device, respectively, to investigate the effect of alternative electromagnetic field on nodulizing degradation. The results show that alternative electromagnetic field plays a positive role on reinforcing desulphurization and deoxidation, and reducing the S and O content in the solidified spheroidal cast iron by alternative electromagnetic field. The results also indicate that the alternative electromagnetic field could restrain nodulizing degradation.
