-4. (canceled)
A process for reversing vulcanization in autoclave with the use of electromagnetic induction to heat straight into an inner metal components of tire;
- the process comprising the following steps:
- (1) loading a tire in the autoclave with no need for any type of assembly;
- (2) choosing predetermined suitable inductors to be used;
- (3) fixing the inductors inside the autoclave which is provided with a motor rotated center axle;
- (4) pitching the suitable frequency and intensity of the inductors according to the materials applied and the kind of tires;
- (5) Autoclave set up:
- time, pressure and temperature are adjusted to begin vulcanization process, which is controlled by a power module that delivers the amount of electromagnetic induction necessary to reversing vulcanization of different kinds of tires.
- (6) the frequency and intensity of induction causing metal molecules to vibrate thus generating heat on the metal inner ply of the tire increasing its temperature;
- and
- (7) the heat generated dissipates through the tire rubber components that reaching the predetermined temperature cause the reversing vulcanization of the tire.
