| Abstract: |
| The effect of the wire distribution modes and coil winding group intervals of the
electromagnetic induction heating coils on the electromagnetic induction heating uniformity of the direct
pressure vulcanization inner mold of tire was studied. The results showed that the wire distribution modes of
the electromagnetic induction heating coils could affect the temperature field on the surface of the drum pad，
and the electromagnetic induction heating coils with the 2-section winding groups provided the best heating
uniformity. In addition，the change of the intervals between coil winding groups would have a huge impact on
the temperature field on the surface of the drum pad. It was found that，when the coil winding group interval
was 50 mm，the electromagnetic induction heating coils had the best heating uniformity. |
