Tire vulcanizing method, and tire vulcanizer

摘要

The present invention relates to a tire vulcanizing method and tire vulcanizer in which an inert gas is circulated, the method for reducing consumption energy and increasing productivity of a tire vulcanization. This tire vulcanizing method includes a supply step of supplying the inert gas to an internal space of the tire via a supply pipe, a discharge step of discharging the gas from the internal space of the tire via a return pipe (31), a circulation step of supplying the gas flowing through the return pipe to the supply pipe (21) by a rotation type circulation device, a heating step of heating the gas circulated via the circulation device (60) by a heating device, an outlet gas temperature detection step of detecting a temperature of the gas flowing through the return pipe by an internal outlet gas temperature sensor (TC31), and a rotating speed decrease step.
