【摘要】 研究导磁体长度和截面尺寸对直压硫化金属内模电磁感应加热均匀性的影响。结果表明：减小导磁体的长度可使得鼓瓦两端磁力线密度下降，使电磁感应加热更均匀，但会导致鼓瓦的加热功率下降，当导磁体长度为170 mm时，直压硫化金属内模电磁感应加热的均匀性最好；增大导磁体的截面尺寸虽然会使得电磁感应加热均匀性有所降低，但可以减小导磁体的涡流损耗和功率损耗，有效解决了导磁体铁损的问题，当导磁体的截面尺寸为20 mm×15 mm时，直压硫化金属内模电磁感应加热效果最好。更多还原

【Abstract】 The influence of the length and section size of the magnetic conductor on the electromagnetic induction heating uniformity of the inner metal mold in direct compression vulcanization was studied. The results showed that reducing the length of the magnetic conductor could reduce the magnetic line density at both ends of the drum pad,making the electromagnetic induction heating more uniform,but it would lead to the decrease of the heating power of the drum pad.When the length of the magnetic conductor was 170 mm,the electromagnetic induction heating uniformity of inner metal mold was the best. Although increasing the section size of the magnetic conductor would reduce the uniformity of electromagnetic induction heating,it could reduce the eddy loss and power loss of the magnetic conductor,effectively solving the problem of iron loss of the magnetic conductor.When the section size of the magnetic conductor was 20 mm×15 mm,the effect of electromagnetic induction heating of inner metal mold in direct compression vulcanization was the best.更多还原
