摘　　要：在Fe-C-S系合金与CaO-MgO-Al2O3溶渣体系间施加电压为2 V的脉冲电场,研究了改变脉冲电场的处理时间对S在渣金两相间分布和迁移特性的影响。试验结果表明,随着脉冲处理时间加长,渣中的硫含量逐渐升高,S在Fe-C-S金属基体上下表面分布趋于均匀,当电场处理时间为60 s时,渣中的硫含量为0.891%,△wS=0.001%,并且金属表面夹杂物明显细化。Pulsed electric field has been imposed on interface between Fe-C-S alloy and CaO-MgO-A1203 slag for different durations to study sulfur distribution and migration between metal and slag. The experi- mental result shows that with the extension of imposing time, sulfur in the slag gradually increases, and evenly distributes on the upper and lower surfaces of Fe-C-S metallic matrix; in addition, inclusions on the metal surface are obviously refined at the same time. The sulfur content in the slag is 0.891 percent and △ws is 0.001 percent when pulsed electric field imposing time is 60 seconds.
