摘要：
Inclusions cannot be sufficiently stretched to adapt extremely strict requirement of saw wire with only conventional inclusion softening art. In order to explore a potential new method to further enhance the deformability of inclusions, Na2CO3 addition should be comprehensively investigated due to the extremely low melting temperature of inclusions containing Na2O. In the present study, an effective method of Na2CO3 addition was put forward and a presumable reaction mechanism between Na2CO3/steel/inclusion/slag was deduced by studying the effect of Fe/Na2CO3 (weight ratio), Na2CO3 addition amount and reaction time on inclusions using a graphite tube resistance furnace. The relations between Na2O content, melting temperature, deformability and crystallization of inclusions were also briefly discussed. Through these studies, the deformability of inclusions was significantly improved on the whole.
